Ms. Jane Coyle-Morris
Role of Antibodies
Antibody interaction with Complement Proteins
Central Role of Helper T-Cells
Large, irregularly-shaped phagocytic cells that act as the body’s scavengers. Macrophages engulf and consume foreign material such as bacteria and viruses.
Arise from stem cells in the bone marrow then migrate to the thymus gland where they develop the ability to recognize foreign antigens in a specific manner.
Detect infection and initiate both humoral and cell-mediated responses (CD4 cells)
Recruited by TH to lyse infected body cells (CD8 cells)
