.Activation of a T-lymphocyte upon exposure to a T-dependent bacterial antigen stimulates a strong immune response, during which large quantities of bacterial-specific antibodies are produced. The T-helper does not, however, possess the ability to synthesize these antibodies. How can you explain this phenomenon

T helper cells don't synthesize antibodies

Explanation:

Helper T cells are one of the most important types of cells during adaptive (acquired) immune responses. These cells activate B lymphocytes that secrete antibodies and macrophages that kill pathogenic organisms. Moreover, helper T cells also activate cytotoxic T cells that secrete molecules in order to destroy infected cells. However, antibodies that recognize and bind to specific antigenic determinants are only produced by B lymphocytes, thereby antibody production is a function that escapes from T helper cell-mediated responses.
