Explanation:
Detailed explanation-1: -TH2 cells initiate the humoral immune response by activating naive antigen-specific B cells to produce IgM antibodies. These TH2 cells can subsequently stimulate the production of different isotypes, including IgA and IgE, as well as neutralizing and/or weakly opsonizing subtypes of IgG.
Detailed explanation-2: -B cell activation is initiated by the binding of antigen to the B cell receptor (BCR) that triggers a number of signaling cascades that ultimately lead to B cell activation.
