Display the epitope on the surface of the APC.
Activate macrophages for fever and inflammation.
Cause the release of interleukin-1 in cellular immunity.

In the realm of immunology, T helper cells (also known as CD4+ T cells) play a pivotal role in orchestrating the immune response. They activate B cells to secrete antibodies and help killer T cells to respond to infected cells. Notably, they also enhance the activity of macrophages, which are crucial for engulfing and digesting pathogens. These cells are like the conductors of an orchestra, making sure that every part of the immune system plays its role in harmony!

In addition to increasing the production of antibodies, T helper cells release cytokines, particularly interleukins, which are key communication molecules. Interleukin-2, for instance, is critical for the growth and proliferation of T cells, while interleukin-1 plays a pivotal role in promoting inflammation. Understanding these processes not only highlights the complexity of immune responses but also sets the stage for potential therapeutic strategies in treat immune-related diseases.
