In order to clarify the beneficial effect of donor-specific blood transfusions (DST) on kidney allograft survival, sera from 16 patients treated with DST were studied using the mixed lymphocyte culture (MLC) serum inhibition test. The results demonstrate that MLC inhibitory factors could be induced in the serum of the recipients after the completion of DST, and that these factors are directed against cells of the recipient but not against cell from the donor. Regarding the correlation with rejection episodes and clinical outcome, a significant improvement in renal transplant survival and reduction in rejection episodes was observed when MLC inhibitory factors were present in post-DST sera. These data suggest that such factors may contain antibodies directed against recognition sites on T lymphocytes, e.g., anti-idiotypic antibodies, and be associated with prolonged graft survival of living-related, high MLC-reactive one-haplotype-mismatched kidney.

UI MeSH Term Description Entries
D007130 Immunoglobulin Idiotypes Unique genetically-controlled determinants present on ANTIBODIES whose specificity is limited to a single group of proteins (e.g., another antibody molecule or an individual myeloma protein). The idiotype appears to represent the antigenicity of the antigen-binding site of the antibody and to be genetically codetermined with it. The idiotypic determinants have been precisely located to the IMMUNOGLOBULIN VARIABLE REGION of both immunoglobin polypeptide chains.

D007668 Kidney Body organ that filters blood for the secretion of URINE and that regulates ion concentrations. Kidneys
D007959 Lymphocyte Culture Test, Mixed Measure of histocompatibility at the HL-A locus. Peripheral blood lymphocytes from two individuals are mixed together in tissue culture for several days. Lymphocytes from incompatible individuals will stimulate each other to proliferate significantly (measured by tritiated thymidine uptake) whereas those from compatible individuals will not. In the one-way MLC test, the lymphocytes from one of the individuals are inactivated (usually by treatment with MITOMYCIN or radiation) thereby allowing only the untreated remaining population of cells to proliferate in response to foreign histocompatibility antigens.
