Background: Diabetic patients (DPs) with foot ulcers can receive autologous cell therapy (ACT) as a last therapeutic option. Even DPs who have undergone organ transplantation and are using immunosuppressive (IS) drugs be treated by ACT. The aim of our study was to analyze the effects IS on characteristics bone marrow-derived stem cells (BM-MSCs). Methods: were isolated from marrow DPs, cultivat...

OBJECTIVE This study investigated the immunoregulatory and protective roles of Yinchenhao decoction, a compound of Chinese herbal medicine, in a mouse model of concanavalin A (ConA)-induced chronic liver injury. METHODS Female BalB/c mice were randomly divided into 4 groups: normal control, ConA model, ConA model treated with Yinchenhao decoction (400 mg/kg, orally), and ConA model treated wi...

The purposes of the present study were to determine the distribution of cells producing cytokines: tumor necrosis factor α (TNF-α) and interleukin 6 (IL-6) in different morphological sections of tonsils in patients with tonsillar hypertrophy (TH) and recurrent tonsillitis (RT), to analyze the level of production of these cytokines in TH and RT and evaluate the potential of peripheral blood lymp...

SUMMARY CD200 and its receptor were recognized as having the multiple immunoregulatory functions. Their immunoregulatory, suppressive, and tolerogenic potentials could be very effectively exploited in the treatment of many diseases, e.g. Alzheimer disease, rheumatoid arthritis, and allergy to name only some. Many research projects are aimed to develop clinically valuable methods being based on ...

Toll-like receptors (TLRs) are a potent trigger for inflammatory immune responses. Without tight regulation their activation could lead to pathology, so it is imperative to extend our understanding of the regulatory mechanisms that govern TLR expression and function. One family of immunoregulatory proteins which can provide a balancing effect on TLR activity are the Leukocyte Ig-like receptors ...

Bifidobacterium breve MCC-117 is able to significantly reduce the expression of inflammatory cytokines in porcine intestinal epithelial (PIE) cells and to improve IL-10 levels in CD4(+)CD25(high) Foxp3(+) lymphocytes in response to heat-stable enterotoxigenic Escherichia coli (ETEC) pathogen-associated molecular patterns (PAMPs), while the immunoregulatory effect of B. adolescentis ATCC15705 wa...

Escherichia coli heat-labile enterotoxin (LT) is an extensively studied adjuvant of mucosal responses. Nevertheless, its mode of action as an adjuvant remains incompletely understood. In this study, we describe a simplified in vitro model with which to look at some aspects of immunoregulation by LT. The interaction of LT with the apical surface of a monolayer of CaCo-2 epithelial cells induces ...
