Helper T cells are the central regulatory cells of the adaptive immune response, among which Th1 cells play a key role in combating intracellular pathogen infections and anti-tumor immunity.

Th1 cell polarization is a core process in adaptive immune responses, precisely driven by key cytokines such as IL-12 and IFN-γ. This process shapes type 1 immunity characterized by macrophage activation and cytotoxic T cell responses, serving as a cornerstone for eliminating intracellular pathogens.
