BIO 202 Immune System

BIO 202 

Here is the picture offered in class about the essay that will be on our immunology exam.

            a. Neutralization

                        i. Blocks viral attachment sites

                        ii. Coats bacterial toxin

            b. Opsonization—bound antibodies enhance macrophage attachment to and phagocytosis of microbes

            c. Agglutination—neutralizes and opsonizes microbes

                        i. Cross linking of antibodies between adjacent antigens

                        ii. Creates a complex that is easier for phagocytes to engulf

            d. Precipitation—similar to agglutination

                        i. Cross-link soluble antigen molecules instead of cells

            e. Complement fixation—antibodies combine with complement system

                        i. Activates complement proteins

                        ii. Complement proteins lesion, then cause cell lysis
