organ transplantation , the body will nearly always reject the new organ(s) due to differences inhuman leukocyte antigen haplotype s between the donor and recipient. As a result, the immune system detects the new tissue as "hostile", and attempts to remove it by attacking it with recipientleukocytes , resulting in the death of the tissue.Immunosuppressants are applied as a countermeasure; the side effect is that the body becomes extremely vulnerable to infections and malignancy, much like in an advanced
HIV infection.References
