thymus - Answer site of t-cell development bone marrow - Answer site of b-cell development and selection secondary lymphoid organs - Answer spleen, lymph nodes, adenoids, tonsil, thoracic duct, appendix, peyer's patch cytokines - Answer molecules secreted by one cell acting on another "hormones" of the immune system effects of cytokines - Answer fever, swelling, recruitment of cells, amplification of immune response chemokines - Answer cytokines that st...

first checkpoint of B cell development - Answer selects for functional heavy chain using the pre-BCR checks for structural integrity of heavy chain second checkpoint of B cell development - Answer selects for functional light chain using the BCR BTK (bruton's tyrosine kinase) - Answer enzyme required for growth and differentiation of pre-B cells important for both checkpoints receptor editing - Answer negative selection process by which the immature B cell continues to ...

primary vs secondary immunodeficiency diseases - Answer primary: inherited defects in components of the immune system secondary: caused by environmental factors such as suppressive drugs or infections Types of primary immunodeficiency - Answer 1. dominant: patents inherit one defective and one normal allele 2. recessive: only manifest in patients who inherit the defective allele from both parents 3. X-linked: caused by recessive defects in genes on the X chromosome defects of IL-2...
