SpletCD4+ T cells (mouse) Mouse CD4 + T helper cells 1 Introduction T helper cells (T H cells) play a pivotal role in adaptive immunity. Following antigen recognition, naive T H cells are activated, undergo further differentiation, and secrete cytokines to promote ('help') and steer the immune response. SpletA plethora of cytokines is not only released by CD4 + T helper cells but also by CD8 + T cells or innate immune cells. 25 CD4 + T cells are also heterogeneous and display differential proliferative capacities and effector functions by producing characteristic cytokines. 26 It is necessary to consider the imbalance of distinct CD4 + T lymphocyte ...
