Objective: 

Course objectives:

This course will enable the students to –

  1. Appraise the detailed knowledge of our immune system to defend against invading pathogens in a logical fashion.
  2. Differentiate and evaluate between innate and acquired immunity; Humoral and cell mediated immunity and the consequences of its failure like autoimmunity, hypersensitivity and immunodeficiencies.
  3. Develop an understanding about the role of effector cells and molecules of the immune system as complements and antibodies.

Cell And Molecular Biology II

Students will :

CO136: Conceptualize how the innate and adaptive immune responses coordinate to fight invading pathogens.

CO137: Demonstrate how  immunomodulatory strategies can be used to enhance immune responses or to suppress unwanted immune responses

CO138: Develop an understanding about hypersensitivity reactions, transplantations or autoimmune diseases.

CO139:Appraise the structure of antigen and antibody and their specific interactions.

CO140: Design strategies to improve existing vaccines and how to approach these.
