Evaluating Recombinant Human IL-2's Impact on T Cell Proliferation
To investigate the effects of recombinant human interleukin-2 (IL-2) in T cell proliferation, an in vitro analysis was conducted. Human peripheral blood mononuclear cells (PBMCs) were triggered with a variety of mitogens, such as phytohemagglutinin (PHA) and concanavalin A (ConA), in the presence or absence of recombinant human IL-2. Cell proliferation was measured by[a|the|their] uptake of tritiated thymidine (3H-TdR). The results demonstrated that IL-2 substantially enhanced T cell proliferation in a dose-dependent manner. These findings emphasize the crucial role of IL-2 in T cell expansion.
