conclusions the changes of treg and th17 cells and their associated cytokines were related to virological and biochemical responses. results in complete and partial-responders, treg cells frequencies and il-10, tgf-β1, il-23 levels were all decreased significantly after na therapy, while th17 cells and the il-17 levels were increased slightly. treg/th17 ratio was only dramatically declined in c...

patients and methods in this cross-sectional study, peripheral mononuclear cells (pbmcs) were isolated from peripheral blood of 29 patients with newly diagnosed pulmonary tb and 19 patients with positive tuberculin skin test. the pbmcs were activated with ppd for 72 hours. activated cells were harvested, rna was extracted and cdna was synthesized. a real-time taqman method was designed and opti...

conclusions the inhibition of tregs is a novel therapeutic approach to cure chronically hbv infected patients. however, further studies are needed to investigate the safety and efficacy of this approach. results considering the increased levels of regulatory cytokines and also regulatory t cells (tregs) during chb, it seems that these cells are deeply involved in chb infection. the inhibition o...

t regulatory cells play a crucial role in immunological unresponsiveness to self- antigens and in suppressing excessive immune responses deleterious to the host. t regulatory cells are produced in the thymus as a functionally mature subpopulation of t cells. they can be induced from naive t cells in the periphery and express their marker as a forkhead/winged helix transcription factor called fo...

our previous study reported that lactobacillus acidophilus ( l.acidophilus )  key laboratory of dairy science  (klds) 1.0738 had an effective impact on inhibiting β-lactoglobulin (β-lg) allergy. this study further investigated the anti-allergic activity of peptidoglycan (pgn) isolated from klds 1.0738. this study aimed to assess whether toll-like receptor 2 (tlr2)/nf-kappab (nf-κb) signaling ac...

Since Gowans first discovered the importance of lymphocytes in the immune response [1], a gradual understanding of their biology has evolved. Initially, B lymphocytes, the effector cells of humoral immunity, were studied in great detail. Largely because of the ability to obtain huge quantities of homogeneous antibodies-the B cell's primary product-through the study of multiple myeloma, tremendo...

CD4+ regulatory (Treg) T cells play a central role in the immune system by potently controlling the responses of other immunocytes. Their activity appears to be essential not only for themaintenanceof immunological self-tolerancebut potentially also for the control of all physiological immune responses whether against normal self-proteins, microbes or cancerous cells. A fuller understanding of ...
