Atopic diseases are complex entities influenced by an array of risk factors, including genetic predisposition, environmental allergens, antenatal exposures, infections and psychosocial factors. One proposed mechanism by which these risk factors contribute to the development of atopic disease is through changes in the production of T helper cell type 1 (Th1) and T helper cell type 2 (Th2) cytoki...
The cytidine deaminases APOBEC3G and APOBEC3F exert anti-HIV-1 activity that is countered by the HIV-1 vif protein. Based on potential transcription factor binding sites in their putative promoters, we hypothesized that expression of APOBEC3G and APOBEC3F would vary with T helper lymphocyte differentiation. Naive CD4+ T lymphocytes were differentiated to T helper type 1 (Th1) and 2 (Th2) effect...
BACKGROUND We aimed to study T-helper 1 (Th1) and Th2 intracellular cytokine expression in peripheral blood lymphocytes of women with recurrent spontaneous abortions (RSA) or infertility with multiple implantation failures after IVF cycles. METHODS Twenty-six women with three or more RSA and 23 with two or more IVF failures (14 with no history of spontaneous abortion (SAB) and nine with more ...
T helper (Th)-2 cells are the major players in allergic asthma; however, the mechanisms that control Th2-mediated inflammation are poorly understood. Here we find that enhanced expression of Grail, an E3 ubiquitin ligase, in Th2 cells depends on interleukin (IL)-4-signalling components, signal transducer and activator of transcription 6 (Stat6) and Gata3, that bind to and transactivate the Grai...
ABSTRACT: Canine atopic dermatitis (cAD) is a multifactorial allergic disease associated with immune dysfunction and abnormal skin barrier. Several immunological mediators play role in its pathogenesis. Such molecules are produced by the activation of T helper lymphocytes (Th) through polarization to Th1 and/or Th2, which contributes different lesion patterns. Acute lesions mediated an Th2 cyto...
Abstract Non-alcoholic fatty liver disease (NAFLD) is an increasing global epidemic associated with chronic inflammation, metabolic disorders, immunosuppression and importantly, increased incidence of primary metastatic cancers. We have recently demonstrated that the immunosuppressive nature NAFLD livers represented by myeloid-derived suppressor cells dysregulated natural-killer T cells, result...
Pregnancy is a unique immunological state in which a balance of immune tolerance and suppression is needed to protect the fetus without compromising the mother. It has long been established that a bias from the T helper 1 cytokine profile towards the T helper 2 profile contributes towards successful pregnancy maintenance. The majority of publications that report on aberrant Th1:Th2 balance focu...
Cytokine signaling/transcription factor cross-talk in T cell activation and Th1-Th2 differentiation.
The secretion of interleukin 2 (IL-2) is a key event in T cell activation. IL-2 allows T cells to enter into the S phase of the cell cycle and divide. After the activation phase takes place, T lymphocytes proliferate and differentiate to generate effector T cells. Thereby, T helper (Th) precursor cells, which are functionally immature, may become Th1 or Th2 effector cells. These subsets are res...
Various molecules participate in different phases of allergic reactions. This means that many genes are encoding molecules related to allergic reactions, such as cytokines, chemokines, and their receptors as effect or molecules. The transcriptional repressor BCL6 has emerged as a multifunctional regulator of lymphocyte differentiation and immune responses. BCL6-deficient (BCL6) mice display T h...
