recurrent aphthous stomatitis (ras) is known as the most common chronic disease of the oral cavity, which affects a range of 5-25% of the population. ras appears to be associated with some human leukocyte antigen (hla) class ii alleles and haplotypes. this study attempts to survey the distribution of hla-drb and -dqb alleles among iranian ras patients and healthy controls. in order to evaluate ...
host genetic factors play a central role in determining the clinical phenotype of human diseases. association between two polymorphic loci in human genome, human leukocyte antigen (hla) and killer cell immunoglobulin-like receptors (kirs), and genetically complex infectious disease, particularly those of viral etiology, have been historically elusive. hence, defining the influence of genetic di...
To simplify the construction of monoclonal antibody (MAb) libraries to complex biological systems, the use of a cascade procedure has been investigated. The procedure continually restricts MAb production to those antigens previously so unidentified. Murine macrophage membranes were detergent-solubilized and purified by Lens culinaris lectin affinity chromatography. Prior to immunization of rats...
CD (cluster of differentiation) Ags are cell surface molecules expressed on leukocytes and other cells relevant for the immune system. CD nomenclature has been universally adopted by the scientific community and is officially approved by the International Union of Immunological Societies and sanctioned by the World Health Organization. It provides a unified designation system for mAbs, as well ...
Background: During pregnancy, the maternal immune system is in close contact with cells and tissue from the semiallogenic fetus .The human leucocyte antigen (HLA) class Ib molecules, HLA-E, -F and -G, are expressed at the materno-fetal interface. Because of the apparent immunoregulatory functions of these proteins, they may be involved in successful acceptance of the semi-allogenic fetus during...
A panel of 377 commercially available mAbs were submitted to the animal homologue section of the 8th International Workshop on Human Leukocyte Differentiation Antigens (HLDA8, Adelaide, Australia) for cross-reactivity studies on different animal species. In this study we describe the results of testing the mAbs on cattle cells by flow cytometry and Western blot. Eight commercial suppliers parti...
Objectives: Throughout evolution high degree of polymorphism of human leukocyte antigens (HLA) has been observed which ensured accommodation and presentation of all possible antigens. Non-classical human leukocyte antigens-G (HLA-G) region shows polymorphism at 5′-upstream regulatory region (5′-URR) and in the 3′-untranslated region (3′-UTR). These polymorphisms have not been explored extensive...
Peptide-based cancer immunotherapy relies on the identification of epitopes recognized by T-lymphocytes. Because of the high degree of polymorphism of human leukocyte antigens and issues of tumor escape from the immune response, the availability of a wide choice of diverse epitopes is essential for the therapist. There are a number of different approaches for identifying new class Iand class II...
Besides their breeding value, swine are increasingly used as biomedical models. As reported in three international swine clusters of differentiation (CD) workshops and in the animal homologue section of the last workshop for the determination of human leukocyte differentiation antigens (HLDA 8), characterisation of leukocyte surface antigens by monoclonal antibodies and other molecular studies ...
objective: hla-g is a nonclassical major histocompatibility complex antigen and is expressed as seven isoforms, including four membrane bound (hla-g1 to –g4) and three soluble (hla-g5 to –g7) forms. the pattern of selective expression of hla-g transcripts in tissues shows the existence of a tight transcriptional control on the gene expression. it has been revealed that cytokines including inter...
