Are HLA antigens
a risk factor for acute GVHD in thalassemic patients receiving HLA-identical stem cell transplantation?
PRA represents the percent of the anti-HLA antibodies in recipient serum against a set panel of HLA antigens
(6,7,8) and it can identify the risk of hyperacute or vascular rejection.
A1, Cw7, B8, DR3 HLA antigen
combination associated with rapid decline of T-helper lymphocytes in HIV-1 infection.
Fearing GVHD, physicians generally refuse to attempt bone marrow transplants that involve more than a single HLA antigen
The other advantage is, if you need a transplant and cannot find an exact HLA antigen
match (say, instead of having all six HLA antigens
match, you only have five, four, or three match), because cord blood has less immunological reactivity (which appears to be the case), you might be able to go to a two-antigen mismatch rather than a complete match and not have a lot of graft-versus-host disease.
In the era of modern molecular pathology, patients can have their entire HLA antigen
genome sequenced from a single swipe of buccal mucosa or an individual hair root.
The codogenic HLA antigen
determines the reject reaction of organism, and is related to immune response and immunological regulation.
sensitization can cause kidney rejection and make patients incompatible with donors who share their tissue type.
At the time of transplantation, a virtual crossmatch is conducted to determine if the patients anti-HLA antibodies are directed against the donors specific HLA antigen
if yes, they are called donor specific anti-HLA antibody (DSA).
Solid organ transplantation requires that recipients are regularly screened for the presence of antibodies directed against the HLA antigen
