Adaptive Immunity and Lymphocytes

What this unit covers

The resources follow adaptive immunity from the big picture to the detail. Overview maps such as THIRD LINE IMMUNE RESPONSE and Hallmarks of the Adaptive Immune Responses set out the basics: the response is specific, it starts after infection, and it is stronger on a second encounter because of memory.

T cells and MHC

A large share of the page is about T cells. The slide set Antigen presentation and MHC explains how MHC I is present on all nucleated cells and how its alpha chains bind beta 2 microglobulin. The mind map T cells +MHC covers antigen recognition, TCR structure, MHC class 1 and 2, superantigens and MHC polymorphism. The deck T cells and immunity asks which MHC CD4 and CD8 cells screen for and what the immunological synapse is.

B cells and antibodies

For the humoral side, the mind map Lymphocyte Maturation & Receptor Diversity walks through maturation stages. The quiz Immunology Block 2 tests antibody structure, including the Fab and Fc regions and how the variable and constant domains relate to idiotype and isotype. Further decks and quizzes look at B cell development, activation, class switching and affinity maturation.

A sensible order

1. Start with an overview map to get the vocabulary.
2. Read Antigen presentation and MHC, then the T cell maps.
3. Move to the B cell and antibody material.
4. Finish with tolerance topics, including the maps on oral tolerance and regulatory T cells.

Use maps to see how ideas connect, then take a quiz straight afterwards. Any question you miss tells you which map or deck to reopen. Flashcards are handy for short recall such as which cell screens for which MHC.
