HLAMatchmaker is a computer algorithm that determines HLA compatibility at the structural level. Donor-recipient histocompatibility is assessed with polymorphic amino acid configurations that represent structurally defined elements of HLA epitopes originally assigned as triplets and more recently as eplets. For many patients, HLAMatchmaker can identify mismatched HLA antigens that can be considered compatible at the structural level. Structurally based HLA matching reduces humoral allosensitization and correlates with good transplant outcome. Moreover, HLAMatchmaker is useful in the analysis of serum antibody reactivity and benefits the strategy of identifying acceptable mismatches for highly sensitized patients.

Tissue Transplantation01:24

Tissue Transplantation

Tissue transplantation is a significant medical procedure involving the transfer of cells, tissues, or organs from a donor to a recipient, with the primary aim of restoring lost functions. This procedure is crucial in treating a broad spectrum of diseases, including kidney diseases, liver failure, heart disease, and certain types of cancers.

Bone Marrow Sampling and Transplants

Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy the...
