  title = {Th17 cytokines expression in leprosy skin lesions.},
  abstract = {<p>Until recently, it was believed that Th1 and Th2 lymphocytes are the only effector cells of the immune response; however, another group of T cells producing cytokines that differ from those observed in the Th1-Th2 model has been identified recently. These cells comprise a third subtype of CD4+ effector T helper called type 17 T helper cells, or Th17(1) . Th17 lymphocytes produce IL-17, IL-17F, IL-6, IL-21, IL-22, and TNF-α, which play a role in both tissue inflammation and neutrophil activation(2) . IL-17 is a potent proinflammatory cytokine that exerts effects on a variety of cells(2) . In leprosy, the cytokine profile of the tuberculoid and lepromatous forms (stable forms) has been extensively investigated and is characterized by a Th1 and Th2 response, respectively(3) . However, the dimorphic forms are highly unstable and complex and Th17 lymphocytes may play an important role in the immunopathology of these lesions. This article is protected by copyright.
