Question

The rejection of a transplanted organ is an example of a(n)_____ condition.
A) autoimmune
B) isoimmune
C) T cell-mediated
D) B cell-mediated

Accepted Answer

The rejection of a transplanted organ is an example of an isoimmune condition, meaning it occurs due to an immune response against tissue from a genetically distinct individual of the same species. It is not considered an autoimmune condition, as the immune response is targeted against foreign tissue rather than the body's own tissues. While T cells and B cells can both play a role in transplant rejection, the key factor in isoimmune rejection is the recognition of foreign antigens by the recipient's immune system.
