The chemokine receptor CCR4 mediates CCL17- and CCL22-driven chemotaxis of Th2 cells into the skin patients with atopic dermatitis (AD). RPT193 is an oral inhibitor that has been developed to treat AD other allergic inflammatory diseases. safety efficacy as monotherapy for moderate-to-severe was previously described in a placebo-controlled, double-blinded Phase 1 study. Here, we present periphe...
In Leishmania (L.) major-infected BALB/c mice Th2-type cells results in disease progression, whereas C57BL/6-infected mice mount a Th1-type response, which leads to control of the infection. Th2 response correlates with IgG1 whereas, Th1 response supports switching to IgG2a subclasses. Since IgG isotype-dominated response depends on different CD4 + T cell subsets, we studied the antigenic profi...
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 t...
Background: Psoriasis is a T cell-mediated autoimmune disease with elevated level of pro-inflammatory cytokines belonging mainly to Th1 pathway. We investigated whether treatment with micronutrients along with methotrexate (MTX) is able to modulate mRNA expression of Th1 and Th2 patterns and its correlation with disease severity. Methods: Thirty plaque type psoriasis patients with Psoriasis ...
Background and Objectives: Multiple sclerosis (MS) is an autoimmune neurodegenerative disease of the central nervous system (CNS). Although, the contribution of various cells such as B cells, CD8+ T cells, microglia/macrophages, dendritic cells, asterocytes and mast cells in the pathogenesis of MS have been demonstrated, however, it seems that autoreactive myelin specific CD4+ T cells pla...
Background: Sepsis is the leading cause of death in critically ill patients throughout the world. The incidence is increasing despite the major advances in the development of antimicrobial agents and other supportive treatments. Based on multiple studies, it has been shown that patient outcome depends on Th1 and Th2 cytokine response. Moreover, whenever the Th2 response is predominant, the seps...
Th2 cells are recruited to the lung where they mediate the asthma phenotype. Since the molecular mechanisms regulating Th2 cell trafficking remain unknown, we sought to determine whether trafficking of Th2 cells into the lung is mediated by G alpha i-coupled chemoattractant receptors. We show here that in contrast to untreated Th2 cells, pertussis toxin-treated Th2 cells were unable to traffic ...
CD4 T cells potentiate the inflammatory or humoral immune response through the action of Th1 and Th2 cells, respectively. The molecular basis of the differentiation of these cells from naive T cell precursors is, however, unclear. We found that GATA-3 was selectively expressed in Th2 cells. GATA-3 is expressed at a high level in naive, freshly activated T cells and Th2 lineage cells, but subsid...
CTLA-4 deficient mice show severe lymphoproliferative disorders with T helper sub-population skewed toward the Th2 phenotype. In the present work, we investigated the role of CTLA-4 in T helper cell subset differentiation. Naïve CD4+ cells were stimulated with anti-CD3 and anti-CD28 mAbs in the presence of either IL-12 or IL-4 to induce polarisation to Th1 or Th2 cells, respectively. Under thes...
