Final answer:
The question asks whether IL-4 leads to plasma cells secreting. The answer is True. IL-4 is a cytokine that contributes to the maturation of B cells into plasma cells, which secrete antibodies as part of the immune response. This transition is crucial for an effective defense against infections.
Step-by-step explanation:
IL-4 is a type of cytokine secreted by T cells that plays a crucial role in the immune response. Specifically, IL-4 helps B cells to multiply and differentiate into plasma cells that produce antibodies. When B cells are stimulated by an antigen, IL-4 along with other cytokines released by T cells support the transition of these B cells into plasma cells.
Plasma cells are specialized white blood cells that produce and secrete large volumes of antibodies, which are proteins that can specifically recognize and bind to antigens, such as pathogens, to target them for destruction by the immune system. The process of a naïve B cell maturing into a plasma cell is essential for the body's ability to fight infections efficiently.
