Final answer:
True. Cytokines produced by APCs can be presented to CD4+ Th2 cells.
Step-by-step explanation:
True. Cytokines are small proteins that play a crucial role in cell signaling and immune responses. Antigen-presenting cells (APCs), such as macrophages and dendritic cells, present antigens to CD4+ T cells. When a CD4+ T cell binds to an MHC II-antigen complex on an APC, both the APC and the T cell release cytokines, which can activate other immune cells or stimulate B cells to secrete antibodies.
