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 (Theory)

 

The student will

CO163. Conceptualize how                                                the innate and adaptive

immune responses coordinate                                                  to fight invading pathogens and cell and organs of immune system CO164. Develop an

understanding                                    about immunoglobulin    structure                              and functions and antibody diversity CO165. Appraise the

antigen and

antibody specific            interactions, MHC and mechanism of humoral and cell mediated immunity CO166. List antigen processing and            presentation               pathways, cytokines and complement system and

hypersensitivity reactions.

CO167. Develop the concept of vaccines, immunodeficiency and autoimmune diseases.

CO168. Contribute effectively in course-specific interaction
