#7 Immunogenetics

Question 1

Autografts (autologous)

Answer 1

Grafts where tissue is moved from one place to another in the same individual

i.e. skin grafts (you won’t get rejection)

Question 2

Isografts (syngeneic)

Answer 2

Transplants between genetically identical individuals

Question 3

Allogenic grafts

Answer 3

Grafts between genetically different members of the same species

i.e. Kidney transplants

Question 4

Xenogeneic grafts

Answer 4

Grafts between members of different species

i.e. pig heart valves to humans

Question 5

Light chains of B cells

Answer 5

Contains 2 identical light chains (isotypes):

Either 2 identical κ (kappa) chains (encoded on chromosome 2)

Or 2 identical λ (lambda) chains (encoded on chromosome 22)

*Can’t have 1 of each- can’t mix them
