Verified step by step guidance1
Understand the role of Helper T cells in the immune response. Helper T cells, also known as CD4+ T cells, play a crucial role in the adaptive immune system by assisting other cells in the immune response.
Learn about class switching in B cells. Class switching is a process that changes a B cell's production of immunoglobulin (antibody) from one type to another, such as from IgM to IgG, IgA, or IgE.
Recognize the interaction between Helper T cells and B cells. Helper T cells provide necessary signals to B cells through direct contact and the release of cytokines, which are essential for class switching.
Identify the specific cytokines involved. Helper T cells secrete cytokines like IL-4, IL-5, and IL-6, which are critical for inducing class switching in B cells.
Conclude that Helper T cells are responsible for inducing class switching in B cells, as they provide the necessary signals and cytokines to facilitate this process.
