Detailed explanation-1: -Vertebrates inevitably die of infection if they are unable to make antibodies. Antibodies defend us against infection by binding to viruses and microbial toxins, thereby inactivating them (see Figure 24-2).
Detailed explanation-2: -Follicular helper T Cells (Tfh). There, they induce the formation of germinal centers, the transformation of B Cells into plasma cells, the production of antibodies with different isotypes, and the production of memory B Cells (35).
Detailed explanation-3: -This means that before B cells can be induced to make antibody to an infecting pathogen, a CD4 T cell specific for peptides from this pathogen must first be activated to produce the appropriate armed helper T cells. This presumably occurs by interaction with an antigen-presenting dendritic cell (see Section 8-1).
