Many studies have been trying to identify genetic markers for ophthalmological diseases, including, among others, the HLA (Human Leukocyte Antigens). Localized on the short arm of chromosome 6, the human leukocyte antigen system is well known for its capacity to confer susceptibility or resistance to different diseases. In view of its accentuated polymorphism, the strength and type of associati...

introduction: as monoclonal antibodies are potential tools for characterization of soluble or cellular surface antigens, use of these proteins has always been considered in infertility and reproduction research. therefore, in this study, monoclonal antibodies against human sperm surface antigens were produced. material and methods: to produce specific clones against human sperm surface antigens...

Human leukocyte antigen (HLA), a system involved in immune response to foreign antigens and autoimmunity, has been strongly implicated multiple sclerosis (MS). Prior research shown that HLA DRB1*15:01 exerts the strongest susceptibility effect, although other alleles have both to, protection against, MS. Here we utilized an immunogenetic epidemiological approach evaluate correlations between po...

The reactivity of lymphoid cells from germfree and conventional CDF rats were compared in mixed leukocyte culture (MLC) with both allogeneic rat leukocytes and with human leukocytes as stimulating cells, and in a graft-versus-host (GVH) assay. There was no difference between germfree and conventional rats in any of these systems. Furthermore, the increase in GVH activity after specific immuniza...

Platelet transfusions are commonly used for prophylaxis and treatment of bleeding. After a transfusion, an increment or "boost" is expected to occur. While a number of factors can contribute to a poor posttransfusion increment, refractoriness is typically defined as failure to achieve an appropriate increment after receiving 2 consecutive transfusions with fresh ABO-compatible platelets. The mo...

background: different studies have demonstrated that a small proportion of healthy individuals receiving the hepatitis b (hb) vaccine do not produce protective levels of anti-hb antibody, a phenomenon which could be linked to certain human leukocyte an-tigen (hla) class-ii alleles or haplotypes. objectives: the present study was under-taken to determine the frequency of hla class-ii alleles in ...

increase leukocyte capture, various experimental conditions, such as the antibody fixing time, incubation time, and leukocyte concentration, were optimized. The results for the CD45 immobilization experiments showed that various experimental conditions, such as antibody fixing time, incubation time, and leukocyte concentration, affected the leukocyte capture efficiencies. We identified the foll...

PURPOSE To investigate the presence of Human Leukocyte Antigens (HLA) in organ cultured corneas, in lyophilised epikeratophakia lenticules prepared by dry state lathing, and in lenticules subjected to prolonged rehydration in Balanced Salt Solution (BSS). METHODS Twelve lenticules and 3 organ cultured corneas were studied for the presence of HLA-ABC (class I), and HLA-DR, -DQ, and -DP (class ...
