Parts of Cellular Immune Response
Requires MHC atigens
Requires antigen-presenting cell (Macrophages)
B Cell activation
B cells combine with antigen or macrophage that displays a digested antigen on its surface, helper T cells contact the displayed antigen
T Cell activation
T cell combines with B cell combined with the antignen, Helper T cell releases cytokines.
B Cell Differentiation
During differentiation, some B cells become plasma cells and release many antibodies, some B cells go dormant until a reinfection.
Strength of secondary immune response
Stronger than primary immune response, due to memory B cells and memory T Cells
Antibody production, localized changes after antibody action, and where antibodies are found
Antibody production: B Cells (Plasma Cells
Localized changes: inflammation, edema, antibody production, vasodilation
Antibodies found- plasma, tissue fluids, exocrine secretions, surfaces of B cells
