Verified step by step guidance

Understand the role of B cells in the immune system: B cells are a type of white blood cell that play a crucial role in the adaptive immune response by producing antibodies.

Learn about interleukins: Interleukins are a group of cytokines (signaling molecules) that are secreted by certain cells of the immune system and have an effect on other cells.

Identify the function of IL-4: Interleukin-4 (IL-4) is known to stimulate the proliferation and differentiation of B cells. It is crucial for the production of antibodies and the regulation of immune responses.

Compare the roles of other interleukins: IL-2 is primarily involved in T cell proliferation, IL-6 is involved in inflammation and the acute phase response, and IL-1 is involved in the inflammatory response.

Conclude that IL-4 is the interleukin responsible for stimulating the production and proliferation of B cells, as it directly influences B cell activity and antibody production.
