Transplantation Flashcards
What is the major barrier to transplantation?
immune response (mostly T cells)
what lymphocyte is involved in 1st and 2nd set rejection reactions?
T cells (mainly CD4+)
This test is referred to as “microcytotoxicity” test
HLA serology typing
What does HLA serology typing usually identify?
Class I HLA loci (HLA-A, B, C)
Can traditional HLA typing identify Class II HLA alleles?
no, needs other testing techniques
Why are HLA labs starting to use qPCR?
increased accuracy and speed
This testing method has resulted in discovery of large number of “micropolymorphisms” in the human genome
HLA loci sequence-based testing
How are HLA haplotypes usually inherited?
one allele from each parent. Rarely, you get one allele from one parent and a combination of both alleles from the other parent
Polymorphic self-proteins that differ in amino acid sequences between individuals give rise to ____
minor histocompatibility antigens
This immunosuppressant blocks calcineurin/calmodulin
Cyclosporin and FK506 (tacro)
