Master Plant Biotechnologist interested in imparting knowledge on biology and medicine.


Aishwarya G Iyer

This course deals with a branch of biology that covers the study of immune systems in all organisms. It has numerous applications in disciplines of medicine , particularly in the fields of organ transplantation , oncology , rheumatology , virology bacteriology , parasitology , psychiatry and dermatology.

English

Immunology - GATE (Biotechnology)

This video gives an overview of the course immunology and lists out the topics which will be covered in this course.

Immunology ( Overview )

This video briefly describes about the innate immune system and the three barriers - physical , chemical and phagocytic and it also explains about the cells in innate immune system - macrophages , dendritic cells , natural killer cells , polymorphonuclear leukocytes.
PS : It is phagocytic* barrier not phagocytotic , the process however is known as phagocytosis.

Immunity ( Part 1 )

This lesson describes about the organs of the immune system - lymphoid organs viz Primary lymphoid organs and secondary lymphoid organs in detail , it also explains about distribution of lymph nodes , GALT ( Gut-associated lymphoid tissue ) , MALT ( Mucosa-associated lymphoid tissue ) & SALT ( Skin-associated lymphoid tissue ).

Organs of the Immune System

This lesson describes about the innate immune response and acquired immune system in detail - characteristics of acquired immune system , cells involved in acquired immunity - B cells and T cells.

Immunity ( Part 2 )

This video talks about the four types of Hypersensitivity reactions in detail.
Type 1 - Anaphylactic reactions
Type 2 - Cytotoxic reactions
Type 3 - Immuno complex reactions
Type 4 - Cell mediated reactions

Hypersensitivity reactions

This video describes about antigen-antibody reactions in detail . It includes three distinct phases of antigen/antibody reactions- primary , secondary and tertiary , Strength of Ag-Ab Interactions- Affinity and avidity.

Antigen - Antibody reaction

This video explains about the structure  of antibodies in detail. It also gives information on the overall function of antibodies.

Antibodies - Structure and function

This video describes about autoimmunity in detail. 
1) General principles
2)Genetic basis of autoimmunity
3) Infections and autoimmunity
4) Mechanisms by which infection may promote autoimmunity
5) Infection and autoimmunity
6) Examples of autoimmune diseases

Autoimmunity

This video briefly describes about antibody diversity - Somatic recombination , somatic mutation , somatic hypermutation , genetic basis for Antibody diversity, organisation and rearrangement of light chain genes , organisation and rearrangement of heavy chain genes & Diversity in antibody specificity.

Antibody Diversity

This video briefly describes about the major histocompatibility complex ( MHC ) - MHC I and MHC II in detail . It also explains about its diversity, processing of exogenous and endogenous antigens , Other genes within MHC region - MHC III.
