Immunology & Medical Microbiology

UNIT – I : History of Immunology and Immune System 22 Hrs
Development of immunology. Types of immunity – innate and acquired; active and passive; humoral and cell-mediated immunity. Primary and secondary organs of immune system – thymus, bursa fabricus, bone marrow, spleen and lymph nodes. Cells of immune system. Identiification and function of B and T lymphocytes, null cells, monocytes, macrophages, neutrophils, basophils and eosinophils.

UNIT – II :  Basics of Immunology 22 Hrs
Antigens – types, chemical nature, antigenic determinants, haptens. Factors affecting antigenicity. Antibodies – basic structure, types, properties and functions of immunoglobulins. Components of complement and activation of complement. Types of antigen-antibody reactions – agglutination, blood groups, precipitation, neutralization, complement fixation. Labeled antibody based techniques – ELISA and Immunofluroscence. Polyclonal and monoclonal antibodies – production and applications. Types of hypersensitivity – immediate and delayed. Autoimmunity and its significance.
