Additional Info:
- T cells: - Cells that mature in thymus gland - Responsible for cell mediated immunity - They divide into specific cells when activated by a pathogen - Cytotoxic T cells: attack foreign or infected cells or both - Helper T cells: Stimulate T and B cells - Suppressor T cells: inhibit T and B cells - Memory Cells: Remain in reserve in case of return of pathogen - B Cells: - Cells mature in bone marrow - Responsible for antibody-mediated immunity (humoral response) - When activated they divide into... - Plasma cells: produce and secrete antibodies - Memory cells: Remain in reserve in case pathogen reappears. |
