background and objectives: infection with human immunodeficiency virus (hiv) results in dysregulation of the cytokine profile. a switch from a t helper 1 (th1) to a th2 cytokine has been proposed as an important factor in progression of hiv infection to aids. the aim of the present study was to assess the level of th1 and th2 cytokines in hiv infected individuals in order to identify the switch...

Objective: In Persian medicine (PM), wet-cupping therapy (WCT) is the most utilized approach. WCT is mostly done between the shoulders, which is referred to as “hejamt-e-aam” in the Persian language. CD4+T cells also refer to T helper lymphocytes play a critical role in the immune system. Naïve CD4+ T cells differentiate into at least four subsets, T helper 1 (Th1), T helper 2 (Th2), T helper 1...

آسم بیماری التهابی مزمن با مشخصه التهاب ائوزینوفیلی و انسداد راههای هوایی است. بیش از 300 میلیون نف ر در سراسر دنیا از این بیماری رنج برده و آمار آن در حال افزایش است. شایع ترین علائم این بیماری شامل خس خس سینه ، سرفه و تنگی نفس می باشد. بسیاری از مطالعات نشان داده اند که فعالیت سلول های t ( t cell ) می تواند با شدت آسم، درجه تنگی مجاری هوایی و پاسخ ائوزینوفیلی مرتبط باشد. درافراد اتوپیک مبتلا ...

Programmed cell death-1 (PD-1) plays an important role in peripheral T cell tolerance, but whether or not it affects the differentiation of helper T cell subsets remains elusive. Here we describe the importance of PD-1 in the control of T helper type 1 (Th1) cell activation and development of forkhead box protein 3 (FoxP3(+)) regulatory T cells (Tr(egs)). PD-1-deficient T cell-specific T-bet tr...

One theory of immune regulation involves homeostasis between T-helper 1 (Th1) and T-helper 2 (Th2) activity. The Th1/Th2 hypothesis arose from 1986 research suggesting mouse T-helper cells expressed differing cytokine patterns. This hypothesis was adapted to human immunity, with Th1- and Th2-helper cells directing different immune response pathways. Th1 cells drive the type-1 pathway ("cellular...

Various evidence suggests that adoptive transfer of polyclonal, tumor-specific, IFN-gamma-producing CD4+ T cells [T helper type 1 (Th1) cells] should be highly efficient for tumor immune therapy. However, this approach could not be tested because very few MHC class II-restricted tumor peptides have been defined. Here we show that stimulation of freshly isolated T helper cells with syngeneic tum...

Two types of T helper (Th) cells have been defined on the basis of their cytokine secretion patterns. The decision of a naive T cell to differentiate into Th1 or Th2 is crucial, since to a first approximation it determines whether a cell-mediated or humoral immune response is triggered against a particular pathogen, which profoundly influences disease outcome. Here we show that the internal beh...

Efficacy of B-cell depletion therapy highlights the antibody-independent effector functions B cells in rheumatoid arthritis (RA). Given type 1 helper T (Th1) abundant synovial fluid (SF) RA, we have determined whether Th1 could generate novel cells. Microarray and qPCR analysis identified CXCL9/10 transcripts as highly expressed genes upon BCR/CD40/IFN-? stimulation. Activated promoted generati...

A large number of CD4+ human T helper type 1 (Th1) clones specific for purified protein derivative and of Th2 clones specific for the excretory/secretory antigen of Toxocara canis, derived from the same individuals, were analyzed for both cytotoxic capacity and helper function for immunoglobulin (Ig) synthesis. The great majority of Th1, but only a minority of Th2 clones exhibited cytolytic act...
