Precarious balance: Th17 cells in host defense.
Lineage-specific responses from the effector T-cell repertoire form a critical component of adaptive immunity. The recent identification of Th17 cells-a third, distinct lineage of helper T cells-collapses the long-accepted paradigm in which Th1 and Th2 cells distinctly mediate cellular and humoral immunity, respectively. In this minireview, we discuss the involvement of the Th17 lineage during ...
متن کاملTh17 cells and IL-17 receptor signaling are essential for mucosal host defense against oral candidiasis
The commensal fungus Candida albicans causes oropharyngeal candidiasis (OPC; thrush) in settings of immunodeficiency. Although disseminated, vaginal, and oral candidiasis are all caused by C. albicans species, host defense against C. albicans varies by anatomical location. T helper 1 (Th1) cells have long been implicated in defense against candidiasis, whereas the role of Th17 cells remains con...
متن کاملHost defense effector molecules in mucosal secretions.
Mucosal secretions contain a range of defense effector molecules including antimicrobial peptides and proteinase inhibitors. These molecules play a central role in host defense against infection, and in a variety of immune and inflammatory reactions. The aim of this study was to analyze the levels of neutrophil defensins, the cathelicidin hCAP-18/LL-37, and the proteinase inhibitors secretory l...
متن کاملTh17 responses and host defense against microorganisms: an overview.
T helper (Th) 17 cells have recently been described as a third subset of T helper cells, and have provided new insights into the mechanisms that are important in the development of autoimmune diseases and the immune responses that are essential for effective antimicrobial host defense. Both protective and harmful effects of Th17 responses during infection have been described. In general, Th17 r...
متن کاملNOD1-Mediated Mucosal Host Defense against Helicobacter pylori
Infection of the stomach with Helicobacter pylori is an important risk factor for gastritis, peptic ulcer, and gastric carcinoma. Although it has been well established that persistent colonization by H. pylori is associated with adaptive Th1 responses, the innate immune responses leading to these Th1 responses are poorly defined. Recent studies have shown that the activation of nucleotide-bindi...
