Contact Hours:

Max. Marks:

Objective: 

The course material has been prepared to help the students-

  1.  To understand the ability of our immune system to defend against invading pathogens in a logical fashion. 
  2. This includes our innate ability to defend against microorganisms (innate immunity); should this first line of defense fail, how we can fight infections (acquired immunity); if we react excessively, what price we pay (hypersensitivity); if we misdirect our defense, what the consequences are  (autoimmunity) and very importantly, can we prevent pathogens from infecting us (vaccination).

Learning outcomes-

At the end of the course, the students should be able to:

  1. Conceptualize how the innate and adaptive immune responses coordinate to fight invading pathogens.
  2. Determine what immunomodulatory strategies can be used to enhance immune responses or to suppress unwanted immune responses such as might be required in hypersensitivity reactions, transplantations or autoimmune diseases.
  3. Critically review the sample literature to determine the strengths and weaknesses of the data published in immunology and its novelty.
  4. Explore strategies to improve existing vaccines and how to approach these.
