Step 1
Promotion of B-cell and T-cell activity
Answer
The primary function of T-helper cells (also known as CD4+ T cells) is to promote the activity of other immune cells, particularly B-cells and T-cells. They play a crucial role in the adaptive immune response by releasing cytokines that stimulate B-cells to produce antibodies and enhance the cytotoxic activity of T-cells. This interaction is vital for effective immune defense against pathogens.
