Distinct roles of interleukin-17 and T helper 17 cells among autoimmune diseases

T Helper 17 Cells in Autoimmune Liver Diseases

Many autoimmune diseases are driven by self-reactive T helper (Th) cells. A new population of effector CD4(+) T cells characterized by the secretion of interleukin (IL)-17, referred to as Th17 cells, has been demonstrated to be phenotypically, functionally, and developmentally distinct from Th1 and Th2 cells. Because the liver is known to be an important source of transforming growth factor- β ...

The Roles of Interleukin-17 and T Helper 17 Cells in Intestinal Barrier Function

Modulation of autoimmune diseases by interleukin (IL)-17 producing regulatory T helper (Th17) cells

Following the discovery of interleukin (IL)-17 producing T helper (Th17) cells as a distinct lineage of CD4+ T helper cells it became clear that these cells play an important role in the host defense against extracellular fungal and bacterial pathogens and participate in the pathogenesis of multiple inflammatory and autoimmune disorders. Depending on the microenvironment, Th17 cells can alter t...

the roles of t helper 1, t helper 17 and regulatory t cells in the pathogenesis of sarcoidosis

sarcoidosis is a systemic granulomatous disorder of unidentified etiology, with a heterogeneous clinical presentation. it is characterized by a reduced delayed-type hypersensitivity to tuberculin and common antigens. the balance between th1, th17 and regulatory t(treg) cells controls t-cell proliferation and activation.the th17/treg ratio in the peripheral blood and bronchoalveolar lavage fluid...

Interleukin-17 and type 17 helper T cells in cancer management and research

Since their recent discovery, T helper 17 (Th17) cells have been frequently detected in the tumor microenvironment of many malignancies, but their clinical implications remain largely unknown. Interleukin-17 (IL-17) detection is commonly related with poor outcomes in colorectal cancers, yet its presence is associated with antitumor responses in ovarian carcinomas. Numerous experimental models i...
