Failures of Host Defense Mechanisms: Pathogens have evolved various means of evading or subverting normal host defenses, inherited immunodeficiency diseases, acquired immune deficiency syndrome.

Unit 5

(10 Lectures)

Allergy and Hypersensitivity: The production of IgE, effector mechanisms in allergic reactions, hypersensitivity diseases. Autoimmunity and Transplantation: Autoimmune responses are directed against self antigens, responses to alloantigens and transplant rejection, self-tolerance and its loss. Manipulation of the Immune Response: Extrinsic regulation of unwanted immune responses, using the immune response to attack tumors, manipulating the immune response to fight infection. Currently available vaccines.

Pre-requisites: Basic understanding of cell biology

Total number of classes: 45

Preamble:

The candidates undertaking this course will gain knowledge about fundamentals of microbiology and immunology with special reference to bacterial, viral and fungal diseases; and host responses against infections. The students will learn about components of immune system and their functions. Gain knowledge on development of immune system and mechanisms of innate, adaptive, allergic, hypersensitivity, autoimmune responses and organ transplantation. The scientific understanding developed through the course will motivate the student to take up advanced immunology courses that has extensive application in medicine.
