ACAAI Review for the Allergy & Immunology Boards Flash Cards ALL CHAPTERS Questions and Answers 100% Solved What is the hapten-carrier effect? Small-molecule antigen requires covalent linkage to a larger carrier to stimulate adaptive immune response. The process is achieved in collaboration between hapten-specific B cells and carrier-specific T cells. This is the basis of developing conjugated vaccines. What are the common superantigens and related diseases? SEB and SEC from Staphyl...

Why do we need immunological tolerance? ~~> This allows us to get random generation of the repertoire of BCR and TCR This means self-reactive specificities will be made Without tolerance, we will get self destruction How do lymphocytes become tolerant? ~~> Central tolerance - they encounter antigens in the central lymphoid organs when they are immature Peripheral tolerance - they encounter antigens in the peripheral tissues in the absence of other necessary signals What is t...

What is the specific/adaptive immunity? ~~> induced by exposure to an infection, very specific and has memory Describe the receptors in the specific immune response ~~> clonaly distributed, a large repitoire at a low frequency What is clonal selection? ~~> during development, cells recognising self material are destroyed leaving only those recognising non-self Whats the role of clonal selection? ~~> reduces the repertoire leaving a pool of mature naive lymphocytes which ca...
