Document Summary
The interaction among behavioural, neuroendocrine, and immunological processes of adaptation. The study of the interaction between psychological processes and the nervous and immune systems of the human body. This includes neutrophils and macrophages, which are phagocytes. Neutrophils and macrophages congregate at the site of injury or infection. Macrophages release cytokines which lead to inflammation, fever, and promote wound healing. Natural killer cells recognize viral infections or cancer cells, lyse cells by releasing toxic factors, important in signaling potential malignancies, limits early phases of viral infections. Lymphocytes have very specific receptors for one antigen. Once activated they divide to create a proliferative response. Humoral immunity is mediated by b lymphocytes: Involves t lymphocytes from the thymus gland. Helper t cells enhance functioning of cytotoxic cells, b cells, and macrophages. Studying distribution of immune cells in blood samples. Assess the amount of circulating lymphokines or antibody level. Assessing the functioning of cells includes examining: Common assessments include: lymphocyte toxicity, phagocytic activity.
