We studied the level of the cytotoxic anti-HLA antibodies (CTA) in 90 hemodialyzed chronic uraemic patients who were on waiting list of transplantation. An association between alleles of HLA A1, B8, DR3 haplotype and the level of CTA was studied. The ratio of the reduced CTA producing subjects was significantly higher in the HLA B8 and DR3 carriers. We could observe the highest ratio in the joint appearance of these alleles. In the presence of HLA A1 allele the ratio was decreased beside B8 or DR3 even as joined attendance of these alleles. Our data suggest a different role of these linked antigens in the regulation of cytotoxic antibody production.

Hybridoma Technology01:31

Hybridoma Technology

Hybridoma technology is used for the large-scale production of monoclonal antibodies. Monoclonal antibodies bind to only a single antigenic determinant or epitope. Such antibodies are used in research, diagnostics, and disease therapy. The hybridoma technology established in 1975 by Georges Köhler and Cesar Milstein was awarded the Nobel Prize in Medicine in 1984 for revolutionizing research and therapy.

Hypersensitivity Reactions: Cytolytic Reactions

Type II hypersensitivity involves IgG and IgM antibodies targeting cell surface antigens, leading to cell destruction. This can occur through complement activation, antibody-dependent cell-mediated cytotoxicity (ADCC), or acting as opsonins for phagocytosis. When excessive, these reactions cause significant tissue damage.Drug-induced hemolytic anemia is a common example, where drugs like penicillin or cephalosporins bind to red blood cells, forming drug-protein complexes. These complexes...
