Document Summary
Immune system was one of poorly understood systems. Psychoneuroimmunoligy: the interactions b. w. behavioural neuroendrocine and immunological processes of adaptation. Immune system: surveillance system of body, distinguishes b. w. self and invaders. Profile of the immune system: natural/specific, 1. Defence against pathogens (cells not specific but overall) Include netrohils and macrophages; both phagocystic engulf target pathogens. Neutrops/macs-congregate at site of injury and release toxins. Natural killers also fight(signal for potential malignancies: 2. Lymphocytes involved-receptor sites-fit with antigens respond to specific invaders. Proliferative response: antigens specific cells divide: both work together. Humeral and cell mediated immunity: humeral: Tc(cytotoxic) respond to specifics and kill by producing toxic. Helper t c ells enhance tc(cytotoxic) functions/b cells by producing lympokines which serve a counter regulatory immune function that suppresses immune activity. Cells in immune system by looking at blood. Counting t/b/nk and assessing amounts of circulating lymphokines/antibody levels: 2. Mitogen- assessing ability to reproduce when stimulated by chemical. Phagocytotic- ability of white cells to ingest.
