Th1 cell responses
WebTh1 responses. Th1 cells preferentially produce IFN-α and IL-2 and are the principal regulators of type 1 immunity, which eradicates intracellular pathogens and tumors. The major effector cytokine produced by Th1 cells is IFN-α. Macrophages are stimulated by IFN-α to phagocytose and generate oxidative bursts that aid intracellular killing of ... WebThe mechanisms that determine whether an L. major–specific T-cell response will be predominately Th1 or Th2 are complex. 35 In some mouse strains, Th2 responses occur because of T-cell responses to one dominant antigen called LACK (Leishmania analogue of the receptors of activated C kinase). 36 In the absence of a T-cell response to this ...

WebT helper 17 cells (T h 17) are a subset of pro-inflammatory T helper cells defined by their production of interleukin 17 (IL-17). They are related to T regulatory cells and the signals that cause T h 17s to differentiate actually inhibit T reg differentiation. However, T h 17s are developmentally distinct from T h 1 and T h 2 lineages. T h 17 cells play an important role … Web12 Aug 2000 · Th1-type cytokines tend to produce the proinflammatory responses responsible for killing intracellular parasites and for perpetuating autoimmune responses.

T cells are particularly important, as they not only control a multitude of immune responses directly, but also control B cell immune responses in many cases as well. Thus, many of the decisions about how to attack a pathogen are made at …
Web11 Apr 2024 · The initiation of Th1 and Th17 responses requires only signals from the activated DC in the lymph node (polarizing signal), whereas Th2 initiation might require two signals. First, the naive T cells require priming by DCs in the lymph nodes; second, they require an additional tissue-derived signal to fully differentiate into effector Th2 cells.
