Answer #1

When a B cell is activated by antigenic interaction, there are two possible outcomes. The activated B cell divides and proliferates into two lineage of cells. Some cells mature as plasma cells which begins to secrete antibodies for the antigen and the other cells becomes long living memory cells which helps improve the immunity against future antigenic invasion. These memory cells upon antigenic invasion(secondary response) readily matures into plasma cells and secretes the specific antibodies.

    Immune system (select the BEST CORRECT statement) When activated by an antigen, B lymphocytes undergo clonal expansion and give rise to both memory cells and plasma cells. Secreted antibody molecules are derived from B cell receptors through an alternative splicing mechanism that removes the receptor’s transmembrane domain. Although B cell receptors are expressed on the surface of B lymphocytes, they function in the tethering and trapping of foreign antigens and are not linked to intracellular signaling cascades. All of the...
