The bark of Ulmus davidiana var. japonica Nakai (Ulmaceae) has been used in traditional Korean medicine for chronic inflammation in the gastrointestinal tract. Here we investigated the frequency and cytokine profile of the major immune cells in the small intestinal lamina propria (SI LP), spleen, and mesenteric lymph nodes (MLNs) of mice treated orally with Ulmus davidiana var. japonica Nakai b...

IL-37, a new member of the IL-1 cytokine family, is a natural inhibitor of innate immunity associated with autoimmune diseases. This study was undertaken to evaluate whether IL-37 has antiarthritic effects in patients with rheumatoid arthritis (RA) and in mice with collagen-induced arthritis (CIA). In this study, we analyzed the expression of IL-37 in PBMCs, serum, and lymphocytes from RA patie...

BACKGROUND Trophoblast expressing paternal HLA-C antigens resemble a semiallograft, and could be rejected by maternal CD4+ T lymphocytes. We examined the possible role in human pregnancy of Th17 cells, known to be involved in allograft rejection and reported for this reason to be responsible for miscarriages. We also studied Th17/Th1 and Th17/Th2 cells never investigated before. We defined for ...

Intestinal dysbiosis, characterized by a reduced Firmicutes/Bacteroidetes ratio, has been reported in systemic lupus erythematosus (SLE) patients. In this study, in vitro cultures revealed that microbiota isolated from SLE patient stool samples (SLE-M) promoted lymphocyte activation and Th17 differentiation from naïve CD4(+) lymphocytes to a greater extent than healthy control-microbiota. Enric...

Recent work has identified a new subset of effector T cells that produces interleukin (IL)-17 known as T helper 17 (Th17) cells, which is involved in the pathophysiology of inflammatory diseases and is thought to be developmentally related to regulatory T (Treg) cells. Because of its importance for Treg cells, we examined the role of IL-2 in Th17 generation and demonstrate that a previously unr...

Plasmacytoid dendritic cells (pDCs) are not only potent inflammatory cytokine producers but also function as antigen-presenting cells (APCs). We have shown that vaccination using CpG-B activated tumor antigen (Ag) presenting pDCs induce Th17 cells that promote intratumoral immune cell recruitment, including antitumor cytotoxic T lymphocytes CTLs. Therefore, strategies targeting both innate and ...

Psoriasis is a common inflammatory disease affecting 1% of the Brazilian population. Th17 and Th1cells are involved with the immunopathogenisis of psoriasis. In this article it is discussed the interaction between the innate immunity (especially dendritic cells and keratinocytes) and adaptive immunity (T lymphocytes) in the pathogenesis of psoriasis.

Within the immune system there is an exquisite ability to discriminate between "self" and "non-self" that is orchestrated by T lymphocytes. Discriminatory pathways guide differentiation of these lymphocytes into either regulatory (Treg) or effector (Teff) T cells, influenced by cues from the naïve T cell's immediate micro-environment as it responds to cognate antigen. Reciprocal pathways may le...

Interleukin (IL)-35 is the latest member of IL-12 family, which plays an important role in other autoimmune diseases. Bone marrow mononuclear cells Coombs test‑positive hemocytopenia, also termed immunorelated hemocytopenia (IRH) is a type of autoimmune-associated diseases. The present study investigated the relationship of IL‑35 in patients with IRH. A total of 43 patients with IRH and 19 norm...
