OBJECTIVE Th17 cells (interleukin-17 [IL-17]-secreting T helper cells) have been implicated in the pathogenesis of rheumatoid arthritis and other autoimmune diseases, but the soluble factors that influence human Th17 differentiation have yet to be fully elucidated. This study was undertaken to investigate the hypothesis that the cytokines secreted by human peripheral blood mononuclear cells (PB...

background and aims: infectious diseases are disorders caused by organisms such as bacteria, viruses, fungi or parasites .the th9 subset develops in response to combined signals from tgf-b and il-4 among a cacophony of other cytokines in the extracellular milieu.t helper 9 (th9) cells,a novel cd4 t cell subset, seem to play a complex role in the outcome of specific immune responses. in this art...

T helper 17 (Th17) cells belong to a recently identified T helper subset, in addition to the traditional Th1 and Th2 subsets. These cells are characterized as preferential producers of interleukin-17A (IL-17A), IL-17F, IL-21, and IL-22. Th17 cells and their effector cytokines mediate host defensive mechanisms to various infections, especially extracellular bacteria infections, and are involved ...

INTRODUCTION In type 2 diabetes mellitus, the adaptive immune system drives systemic inflammation, promoting insulin resistance and related complications, such as diabetic nephropathy. Increased infiltration of activated T lymphocytes has been found in patients with diabetic nephropathy. T-cell influx and accumulation are the factors that aggravate diabetic nephropathy and link with glomerular ...

SM934 is an artemisinin analogue with immunosuppressive properties and potent therapeutic activity against lupus-like diseases in autoimmune mice. In this report, the therapeutic efficacy and underlying mechanisms of SM934 on rheumatoid arthritis (RA) was investigated using collagen-induced arthritis (CIA) in DBA/1J mice. We demonstrated that SM934 treatment alleviate the severity of arthritis ...
