While autoimmune diseases have been linked with genetic polymorphisms of co-stimulatory markers [21, 22], the functional check details implications have not yet been fully deciphered. Genetic polymorphism,

of course, may compromise not only the function of these molecules but their detection by antibodies. The lack of cell surface CD28 prompted the investigation of the possible expression of alternative co-stimulatory molecules, PD-1, ICOS and 4-1BB, by CD8+CD28− Treg. The expression of all these molecules was higher on RA SF CD8+CD28− cells compared with paired PB Treg, perhaps reflecting the higher activation status of the SF cells. The SF cytokine milieu also contains high local concentrations of IL-15 and IL-12 which down-regulate CD28 but enhance 4-1BB, ICOS and PD-1 expression by CD8+ T cells and increase CD8+ cell survival [23]. CD4+CD25+ Treg display attenuated regulatory function following 4-1BB expression [24]. As 4-1BB expression was reduced in RA(TNFi), this raises the

question as to whether or not it might be a component of the improved suppressor function by CD8+CD28− Treg following therapy in RA(TNFi) patients. The ability to suppress T cell responses may therefore be a balance between the pro-proliferative drive of 4-1BB and the inhibitory effect of other Smoothened antagonist mediators, such as PD-1. Overall, a relatively low expression of PD-1 and ICOS was shown by all CD8+CD28− Treg samples. Nevertheless, PD-1 has been linked positively to CD8+CD28− Treg with suppressor function in lupus-prone mice [25]. Therefore, it was notable that PD-1 expression by RA(TNFi) was increased compared with RA(MTX), although still below healthy control levels. For further insight into the defective CD8+CD28− Treg in RA, cells were used in cross-over co-culture experiments between the RA(MTX) and HC subjects. RA(MTX) CD8+CD28− Treg remained unable to suppress allogeneic healthy or RA responder

cells, whereas HC CD8+CD28− cells suppressed allogeneic HC responder cells but not RA(MTX) responder T cells. This finding complements the fact that responder T cells had reduced sensitivity to CD4+CD25hi Tregs in active SLE [26] and type 1 diabetes patients [27], suggesting that in autoimmune diseases Treg activity is hampered by both defective IMP dehydrogenase Treg function and the relative insensitivity of the responder cells. The effect of TNF inhibitor on the ex-vivo phenotype and function of CD8+CD28− cells, such as the increase in IL-10R expression on RA(MTX) T cells, suggests strongly that these cells are only temporarily incapacitated by TNF-α and when this is removed from the environment the activity appears to return to normal. However, RA(TNFi) expression of IL-10R remained lower than normal HC expression and suggests that other mediators are involved. Continuing these studies, the role of IL-10 and TGF-β is under further investigation. Longitudinal studies will be performed to address the effect of therapy on CD8+CD28− Treg.

Dysbacteriosis of intestinal microflora induces altered immune responses and results in disease susceptibility. buy Ruxolitinib Dendritic cells (DCs), the professional antigen-presenting cells, have gained increasing attention because they connect innate and adaptive immunity. They generate both immunity in response to stimulation by pathogenic bacteria and immune tolerance in the presence of commensal bacteria. However, few studies have examined the effects of intestinal dysbacteriosis on DCs. In this study, changes of DCs in the small intestine of mice under the condition of dysbacteriosis induced by ceftriaxone sodium were investigated. It was found that intragastric

administration of ceftriaxone sodium caused severe dysteriosis in mice. Compared with controls, numbers of DCs in mice with dysbacteriosis increased significantly (P = 0.0001). However, the maturity and antigen-presenting ability of DCs were greatly reduced. In addition, there was a significant difference in secretion of IL-10 and IL-12 between DCs from mice with dysbacteriosis and controls. To conclude,

c-Met inhibitor ceftriaxone-induced intestinal dysbacteriosis strongly affected the numbers and functions of DCs. The present data suggest that intestinal microflora plays an important role in inducing and maintaining the functions of DCs and thus is essential for the connection between innate and adaptive immune responses. “
“Laboratory of Mucosal Immunology, Department of Medicine, University of California, La Jolla, CA,

USA Thymic stromal lymphopoietin (TSLP) is constitutively secreted by intestinal epithelial cells. It regulates gut DCs, therefore, contributing to the maintenance of immune tolerance. In the present report, we describe the regulation of TSLP expression in intestinal epithelial cells and characterize the role of several NF-κB binding sites present on the TSLP promoter. TSLP expression can oxyclozanide be stimulated by different compounds through activation of p38, protein kinase A, and finally the NF-κB pathway. We describe a new NF-κB binding element located at position –0.37 kb of the promoter that is crucial for the NF-κB-dependent regulation of TSLP. We showed that mutation of this proximal NF-κB site abrogates the IL-1β-mediated transcriptional activation of human TSLP in several epithelial cell lines. We also demonstrated that both p65 and p50 subunits are able to bind this new NF-κB binding site. The present work provides new insight into epithelial cell-specific TSLP regulation. A single layer of columnar intestinal epithelial cells (IECs) physically separates the intestinal lumen from the underlying mucosal immune cells and defects in their barrier function are associated with inflammatory bowel diseases [1, 2].

Most groups used columns containing sheep anti-IgG antibody and protein A agarose for the removal of autoantibodies. The effect of protein A agarose column immunoadsorption is non-specific, removing pathologic and non-pathologic antibodies [13]. Because of the concern of humoral immunodeficiency due to this non-specific removal, most groups (including ours) supplement immunoglobulin after completion of IA therapy. A Japanese

group used a tryptophan column with a high specificity for the IgG-3 subclass in 16 patients with non-ischaemic DCM and noted a significant decrease in plasma B-type natriuretic peptide [23]. The authors recommend that the selective removal of IWR-1 nmr IgG-3 does not necessitate immunoglobulin supplementation. Not all studies using the IA therapy in patients with non-ischaemic DCM yielded uniform results. Cooper and coworkers [13] pointed out that the response to IA treatment on regional LV function is not uniform, although the quality of life assessment yielded significant improvement up to 6 months after IA in patients with chronic DCM. Doesch and coworkers [14] performed IA in a series of 27 patients with chronic non-familial DCM and reported on an improvement of markers of heart failure severity (NT-pro-BNP) in a subset of

patients only, with a non-significant improvement in LV systolic function indices. Also, in the present study, we noted an improvement of systolic LV function (as defined as an increase in LV ejection fraction >5% after a 6 months observation period) in selleck chemicals llc only Meloxicam 67% of patients with iDCM, and in the remaining patients, the systolic LV function remained almost unchanged (at least during a 6-month follow-up). This obvious discrepancy between the published studies may be related to several aspects, among others the lack of standardized selection criteria for the underlying cardiac disease (chronic non-familial DCM, non-ischaemic DCM, idiopathic DCM, chronic DCM, iDCM, healed iDCM), and differences in the definition of ‘benefit of

IA therapy’. Furthermore, a randomized, prospective study is still lacking; thus, the scientific evidence for a beneficial effect of removal of IgG-3 from blood circulation (versus an adequate control group) on cardiac function is unknown. Autoantibodies belonging to IgG3 group may play a pivotal role in cardiac dysfunction of patients with iDCM. Staudt et al. [21] could show in a case–control study that Protein A agarose column immunoadsorption in conjunction with an improved treatment regimen for IgG3 elimination induces hemodynamic benefit in patients suffering from DCM. The present study focuses on Tregs in response to IA therapy and intravenous IgG substitution. There is little doubt that the cell-mediated immunity is a key player in the pathogenesis of myocarditis and post-inflammatory cardiomyopathy. In knockout mice, elimination of both CD4+ and CD8+ T cells protected the animals from coxsackie B3 viral myocarditis.

5). Taken together, these click here data suggest that astrocytes might be able to develop into antigen-presenting cells during the late phase of EAE, thereby contributing to lymphocyte-mediated disease pathogenesis and resulting in severe presentation

of disease. CNS factors have been shown to contribute equally (with immune cells) to MS disease progression [4]. Data presented in this report demonstrate that astrocytes act both as suppressors and promoters of MOG35–55-specific lymphocyte responses; these are associated closely with the disease stage and the local microenvironment. Therefore, targeting of astrocytes during the optimal time-points in the course of disease progression may be used to develop novel EAE therapeutic strategies.

“Acute graft versus host disease (aGVHD) remains a life-threatening complication of bone marrow transplantation. Here we show that IL-27, a member of the IL-12 cytokine family, plays an essential role in a parent-to-F1 murine aGVHD model, using B6 mice as parents and B6D2 mice as F1 recipients. IL-27 is transiently detectable Selleck AZD8055 in the serum

of B6D2 recipients of B6 spleen cells, with a peak at day 10. Treatment with anti-IL-27p28 mAb MM27.7B1 (αp28Ab), at the time of and six days after B6 cell transfer, Cytidine deaminase blocked GVHD. Protection was associated with host cell survival and undiminished engraftment of donor cells, lack of host B-cell depletion, increased Th2-type immunoglobulin production, a decrease in serum IFN-γ, a drop in anti-H-2Dd cytotoxic T lymphocyte activity and an increase in Foxp3+ T cells. We therefore conclude that IL-27 plays a critical role in the parent-to-F1 model of aGVHD and that blocking IL-27 could have therapeutic relevance. “
“According to the hygiene hypothesis, the increased incidence of allergic and autoimmune diseases in developed countries is mainly explained by the decreased contact between the human population and certain environmental agents as lactobacillus, mycobacteria and helminths. In this study, we evaluated the effect of multiple infections with Strongyloides venezuelensis on the development of experimental autoimmune encephalomyelitis (EAE) in Lewis rats. Multiple infections before EAE induction were not able to change the evolution of the disease. No alterations were observed in weight loss, clinical score and inflammation intensity at the central nervous system. The presence of significant levels of parasite-specific IgG1 but not IgG2b suggested a Th2 polarization.

In order to understand the mechanisms leading to impaired functionality

of chronically activated DCs we determined the kinetics and extent of the LPS induced IL-12, TNF and IL-6 gene expression in MoDCs developed from peripheral blood monocytes in a 2-day culture in the presence or absence of 5 ng/mL LPS. We used this relatively low LPS concentration as it did not induce a strong DC activation measured at the level of inflammatory cytokines or the expression of CD86 and CD83 at day 2 but it consistently induced a desensitization of developing MoDCs to further LPS-mediated activation (Fig. 1A). Thus inhibitory signals contributing to DC inactivation may not be obscured by a strong DC activation. We analyzed MoDC activation following Hedgehog antagonist a short, 2-day culture, to better represent AT9283 clinical trial an in vivo situation when monocyte precursors enter inflamed tissues and differentiate to DCs in the presence of activation

signals that readily induce effector functions. At day 2 we observed the induction of CD1a and CD209 (DC-SIGN) and the downregulation of CD14 on a high proportion of developing MoDCs underlying the hypothesis that monocytes are able to obtain DC phenotype in such short period (Supporting Information Fig. 1). As Fig. 1B shows, a 2-day LPS pre-treatment completely blocked the induction of IL-12, TNF and IL-6 genes by a second LPS stimulus whereas, without LPS pre-treatment MoDCs responded to LPS signal with Protein kinase N1 a rapid and strong induction of these genes. To study if the tolerization of developing MoDCs by an early encounter with stimulatory signals is a general phenomenon, or if it is specific for single LPS stimulus, we treated the cells with a wide variety of stimulatory factors, applied separately or in combination with LPS between day 0 and 2 of MoDC cultures. Few of these signals induced detectable TNF production when applied to

monocytes alone, namely, heat-killed Staphylococcus aureus (HKSA), an inducer of TLR2 signals and CL075 that triggers TLR7/8 (Fig. 1C). LPS synergistically increased the levels of TNF when combined with CD40L, the TLR2 ligands HKSA or Pam3Cys, with CL075 or with the combination of TNF, IL-1 and IL-6. No activation or very low cytokine levels were observed with TNF, IFN-γ and the TLR3 ligand poly(I:C). Despite the strong initial MoDC activation induced by several types of stimuli, when the cells were washed and reactivated by 100 ng/mL LPS at day 2, we observed a complete inhibition of TNF production in MoDCs that differentiated in the presence of CD40L, HKSA, Pam3Cys, CL075, TNF or the combination of TNF, IL-1 and IL-6 (Fig. 1C, right panel). The 48 h presence of LPS resulted in a persistent DC inactivation both when LPS was added alone and when it was combined with any of the other activation signals.

Preliminary data showed that ER-MP58+ cells do not express Flt3 and do not produce pDCs when cultured in the presence of Flt3 in the fetal and pre-diabetic pancreas. This suggests that our pancreas DC precursor is distinct from the MDP or CDP. We therefore assume that the local pancreatic precursor has a unique phenotype different

from peripheral blood monocytes and precursors Selleck Aloxistatin for cDCs in the BM. Our study has limitations. One could argue that the local precursors are not present in the “pancreas-anlage” itself, but in the vicinity of this tissue in specialized blood-forming tissues, like the aorta-gonad-mesonephros (AGM) and the fetal liver. In this study the preparation method excludes these organs, which strongly argues in favor of a presence of the precursors in the fetal pancreas itself. Second, the local pancreatic precursor could simply represent early seeded monocytes in the tissues. Indeed, the local pancreas DC precursor has

a similar phenotype as blood monocytes, except for the lower CD11c expression on the Ly6Clow cells and is expressing ER-MP58, which is a marker for both myeloid precursors in the BM mTOR inhibitor and peripheral blood monocytes 15. Upon GM-CSF stimulation the local ER-MP58+ cells isolated from fetal pancreas displayed a high proliferative activity. Such a proliferation was not observed in cultures of ER-MP58+ monocytes isolated from NOD peripheral blood. It is known that blood monocytes are nondividing cells 24. These data, the presence of ERMP58+ cells in the pancreas from embryonic live onwards and the observation of Ki-67+ER-MP58+ cells in the pre-diabetic pancreas support our conclusion that this ER-MP58+ cell is a myeloid precursor cell distinct from a peripheral blood monocyte. However, the possibility that migrating blood monocytes are modified by the microenvironment of Farnesyltransferase the pancreas and obtain a proliferative capacity cannot be excluded completely.

The proliferation/differentiation aberrancies of local NOD pancreatic DC precursors described here are very similar to the aberrancies previously found by us in DC precursors of the BM in the animal models of type 1 diabetes 29. DC precursors in BM of NOD mice and BB-DP rats also show proliferation/differentiation abnormalities and from these precursors abnormal “steady state” DCs arise with a spontaneous high pro-inflammatory set point 29, 30. These abnormal DCs have a high level of NF-kB and a high acid phosphatase, high IL-12 and low IL-10 expression 31–34. These DCs are incapable of sufficiently sustaining the proliferation of Treg-cell populations in the NOD mouse and BB-DP rat 35, 36. It has been shown that correction of these DC abnormalities prevents the development of autoimmune diabetes 37, 38. It is tempting to speculate that the locally generated DCs in the pancreas of NOD mice show a similar pro-inflammatory set point as their BM correlates and cannot sustain Treg cells sufficiently.

The distal end of the tibia was elevated on the pedicle of the find more tibialis anterior vessels. The vascularized tibial flap was shifted distally and inserted into the graft bed in the talus to form a bridge between the tibia and the talus. The talotibial joint was completely fused 2 months after surgery. Three months were required before the patients could walk bearing full weight.

“In the last decade surgical training

is being revolutionized by two novel concepts that have been introduced to almost all branches of surgery including and most recently to microsurgery. These two concepts are: objective assessments of surgical skills and the nurturing of surgical skills in a simulation laboratory setting. Acquiring surgical skills in the laboratory

setting can help move the microsurgical learning curve from the patient to the laboratory and this will in turn improve patient safety. In order to optimize microsurgical training through a competency based training programme, it is imperative for microsurgical educators to understand microsurgical skill acquisition. This requires accurate objective assessment tools that can define and quantify microsurgical competency. This article aims to review the current literature on the various objective assessment tools adapted for microsurgery Selleckchem Idasanutlin and attempt to identify the gaps that need to be addressed by research in microsurgical education to establish the ideal objective assessment tool. © 2013 Wiley Periodicals, Inc.

“Introduction: The superficial inferior epigastric artery (SIEA)

STK38 is a useful pedicle in supply to the lower abdominal integument, with its use sparing damage to rectus abdominis muscle or sheath. However, it is limited in usefulness due to its anatomical variability. While previous anatomical studies have been limited in number and study design, the use of preoperative imaging has enabled the analysis of this vasculature in large numbers and greater anatomical detail. Methods: A clinical anatomical study of 500 hemi-abdominal walls in 250 consecutive patients undergoing preoperative computed tomographic angiography (CTA) prior to autologous breast reconstruction was undertaken. The presence, size, location, and branching pattern of the SIEA were assessed in each case. Results: The SIEA was identified in 468 cases, an incidence of 94%. Its mean diameter was 0.6 mm, and in 24% of cases was of a diameter >1.5 mm. SIEA location was highly variable, with mean position 2-cm lateral to the linea semilunaris (range 0–8 cm lateral), and relationship to the superficial inferior epigastric vein (SIEV) was also highly variable, with the distance between them ranging from 0.3 to 8.5 cm apart.

Lymphocytes were extracted from whole blood samples of 16 young healthy donors (28 ± 7 years,

five female and 11 male). Exclusion criteria for these donors were a history of cancer, rheumatic diseases, acute and chronic selleck compound infections, cartilage injury and OA. The study protocol was approved by the ethics committee of the University of Heidelberg, Germany. Both patients and blood donors provided informed consent. The procedures followed were in accordance with the Helsinki Declaration of 1975, as revised in 2000. Mononuclear cells (MNCs) were isolated from bone marrow samples by Ficoll Paque plus (GE Healthcare, Uppsala, Sweden) gradient centrifugation. MNCs were then resuspended in culture medium at a density of 5 × 105 cells/cm2 (= 2·5 × 106 cells/ml). Culture medium contained Dulbecco’s modified Eagle’s medium low glucose (DMEM-LG; Invitrogen, Karlsruhe, Germany), supplemented with 10% fetal calf serum (FCS; Biochrom, Berlin, Germany) and 1% penicillin/streptomycin

(Invitrogen). The cells were cultured in 175 cm2 cell culture flasks (Nunc, Roskilde, Denmark) at 37°C with 6% CO2 in a humidified atmosphere. After 24 h, with the first media exchange, non-adherent cells were discarded; afterwards, medium replacement was carried out every 72 h until the cells reached an 80% confluent layer. The cells were then detached with trypsin https://www.selleckchem.com/products/napabucasin.html (Biochrom), washed with complete medium and counted (trypan blue 0·4%; Sigma-Aldrich, Steinheim, Germany). Afterwards, MSCs were replated and cultured under the conditions described above until reaching confluence at passage 2. The ability of MSC to differentiate into chondrogenic,

adipogenic and osteogenic lineages was demonstrated according to protocols described previously [32]. MSCs were allogeneic to the lymphocytes in all co-culture experiments. Peripheral blood mononuclear cells (PBMC) were collected from whole blood samples using Ficoll Paque plus (GE Healthcare, Uppsala, Sweden) gradient centrifugation. PBMC were then separated into a mixture of CD4+CD25– and CD4+CD25+CD127– cells using magnetic separation (CD4+CD25+CD127dim/– regulatory T cell Isolation Kit II, LS and LD columns, MidiMACSTM separator, all from Miltenyi Biotec, Bergisch Gladbach, Germany). The Ribonucleotide reductase isolated cells were then analysed for CD4, CD25, CD127 and forkhead box protein 3 (FoxP3) (see below). MSCs derived from bone marrow (B-MSCs) and synovium (S-MSCs) from 18 patients were co-cultured with CD4+ T cells enriched in Tregs for 5 days in DMEM-LG (Invitrogen) supplemented with 10% FCS (Biochrom) and 1% penicillin/streptomycin (Invitrogen). The cells were resuspended in 48-well plates, each well containing 1 ml of medium and cells in various concentrations: T cells/MSCs 4:3 (37 500 T cells/cm2 and 28 125 MSCs/cm2), 2:1 (37 500 T cells/cm2 and 18 750 MSCs/cm2) and 4:1 (37 500 T cells/cm2 and 9375 MSCs/cm2).

Afterwards, slides were mounted with Vectashield (Vector Laboratories). Images were obtained via confocal laser microscopy (LSM 510 META scanning; Zeiss, Göttingen, Germany). A semiquantitative analysis of dermal positive cells for CD163 and IDO in skin lesions of BT (n = 6) and LL (n = 6) patients was performed and classified as: (−) no positive cells, (+) presence of few positive cells (up selleck inhibitor to 5% of cells), (++) positive cells present in focuses on the inflammatory infiltrate, comprising 20% of cells, (+++) several positive cells, comprising 50%, and (++++) numerous positive cells, representing most of the cellular infiltrate (more than 50% of cells). The analysis of results was performed twice with no disagreement

on the issue. CD163 expression was quantified by Western blot analysis. As previously described, protein extracts were obtained [6] from 30 slices (10 μm) of frozen patient skin biopsies (BT, n = 4 and LL, n = 4) after which 30 μg of the extracts were loaded in 12% SDS-PAGE and blotted onto nitrocellulose Ku-0059436 datasheet membranes (Bio-Rad) with a semi-dry transfer cell (Bio-Rad). CD163 expression

was evaluated after incubation with monoclonal mouse anti-human CD163 clone EDHu-1 (AbD Serotec, EUA) (1: 100) and monoclonal mouse anti-human Tubulin (Sigma-Aldrich, St. Louis, Missouri, USA) (1: 10000). Results were visualized through an enhanced chemiluminescence detection system (ECL; Amersham Biosciences, Piscataway, NJ, USA). Total RNA was extracted from frozen skin fragments (LL, n = 5 and BT, n = 5), which were repaired using the Trizol reagent (Invitrogen Corporation, Carlsbad, CA, USA). The cDNA synthesis, using the

Taqman PCR, was performed as described above [6]. Glyceraldehyde-3-phosphate Avelestat (AZD9668) dehydrogenase (GAPDH) was used as an endogenous control and IDO, IL-10, and CD163 mRNA were quantified via the 2−ΔCt. Immunofluorescence was performed to verify the expression of CD68+, CD163+, and IDO+ cells. The skin macrophage cells were fixed in paraformaldehyde 4% and then incubated with the primary antibodies for 2 h at room temperature. After washing, the secondary antibody (anti-IgG1 for CD163 and CD68 and anti-IgG for IDO) was incubated and the nucleus was marked with DAPI. The images were obtained from Microscope Axio Observer Z1 (Carl Zeiss, Göttingen, Germany) via Axiovision 4.7 software. Cell isolation from skin biopsies was performed as previously described by Moura et al. [38]. Peripheral blood mononuclear cells (PBMCs) were isolated under endotoxin-free conditions from heparinized venous blood by Ficoll-Hypaque (Pharmacia Fine Chemicals, Piscataway, NJ, USA) density centrifugation. PBMC were then cultured in tissue culture plates at 37°C/5% CO2. Monocyte purification was done for 2 h adherence in 24-well plates (Costar, Cambridge, MA, USA) at 2 × 106 cells per well. Live and dead ML at an MOI (2.5; 5 and 10: 1) isolated from LL leprosy patients, E. coli (5: 1), M.

frondosa (approximately 3%) is rich in immunostimulatory substances like proteoglucan [42, 43] and β-glucans [4]. Accordingly, major effects of AndoSan™ are probably mediated by binding of sugars to TLR-2 [12, 44], but also to the dectin-1 receptor [13, 45] and the lectin-binding site of CD11b/18 [14, 46] and possibly CD11c/18 [15]. In line with our results on the reduction in faecal calprotectin in patients with UC, anti-inflammatory effects of the β-glucan pleuran, isolated from the fruiting bodies of Pleurotus ostreatus, has been reported when given orally or intraperitoneally

in rats with experimentally induced colitis [47]. Thus, β-glucans seemed to have an anti-inflammatory effect on the colonic mucosa both when Akt inhibitor administered directly to the gastrointestinal tract or indirectly to the peritoneum. Accordingly, two paths of direct and indirect anti-inflammatory effects may be operating concerning both reduction in faecal calprotectin (UC) and blood levels of cytokines in these patients with IBD. In another study in rats [48] given AbM extracts orally for 1–2 weeks, several anti-inflammatory effects were observed. Examples were reductions in rat paw oedema induced by nystatin, neutrophil migration

to the peritoneal cavity and arthritis induced by Freund’s adjuvant. As to the explanation why AndoSan™ in our study both had a local effect in patients with UC by reducing faecal calprotectin and probably a systemic one in patients with UC and CD by reducing foremost GPCR Compound Library cost levels of pro-inflammatory Fossariinae cytokines is intriguing and has recently been discussed [18]. Briefly, it is commonly believed that carbohydrates larger than monosaccharides are not absorbed from the human gut. However, in murine models [49, 50], uptake of β-1,3-glucans across the gut wall, probably by microfold cells (M cells) and gastrointestinal macrophages in Peyer’s patches for transport to the reticuloendothelial system and blood [51, 52], has been demonstrated. Presumably, a similar mechanism was operating in humans for intestinal absorption of small and

immunomodulatory bioactive β-glucan fragments into the lymphoid system and blood. In addition, AbM contains absorbable low molecular weight antioxidant substances [53], which downregulate the levels of reactive oxygen species (ROS). This may be of relevance in patients with IBD concerning reduction in IL-1β because inhibitors of ROS reduce synthesis of this cytokine in macrophages [54]. In conclusion, consumption of an AbM-based medicinal mushroom extract for 12 days by patients with IBD resulted in no side effects and a decline of especially pro-inflammatory and chemotactic cytokines as well as a reduction in faecal calprotectin in patients with UC. These promising results warrant further studies on additional biological parameters and potential improvement of clinical outcome in these patients.
