Question

Which interleukin responsible for producing IgE from B cells

• A. IL 1
• B. IL 3
• C. IL 4
• D. Both B & C

Answer 1

The Correct Option is C

In pharmacology and immunology, interleukins are a group of cytokines that play crucial roles in immune system regulation. The question focuses on identifying the interleukin responsible for promoting the production of Immunoglobulin E (IgE) from B cells.

In this context, IgE is a type of antibody that plays a significant role in allergic reactions and asthma. The production of IgE is regulated by specific interleukins, signaling molecules used for communication between immune cells.

Interleukin 4 (IL-4) is specifically known to induce the differentiation of naive helper T cells into Th2 cells. These Th2 cells subsequently help B cells to switch their production towards certain antibodies, including IgE.

Thus, IL-4 is directly responsible for the production of IgE by B cells.

Hence, the correct answer is IL 4.
