Antiglobulin Test

Background. Rhesus phenotype has been determined in 404 persons which have problems with blood groups identification. Genetic typing of antigen RhD variants was performed in 73 individuals. Objective of the work was to give molecular and serological characteristics of the antigen RhD weak types.Materials and methods. Method of rhesus phenotype determination in direct agglutination test on plane by using of anti-D, anti-C, anti-c, anti-Cw, anti-E and anti-e monoclonal antibodies; gel method of rhesus phenotype determination; methods of genetic typing of RhD; methods of antigen RhD determination in the classic indirect antiglobulin test and in the gel indirect antiglobulin test; method of antigen RhD determination in the saline agglutination test.Results. Serological methods identified 73 red blood samples with the weakened expression of RhD antigen. Molecular methods showed the reasons of weakness of antigen expression. Three RHD*D weak types which are common in Russians (RHD*D weak type 1–3) were identified and for the first time 3 types were found – RHD*D weak type 67, RHD(G255R) and RHD(JVS5-38del4). Serological characteristic of RhD weak types was given. It was shown that combined using of monoclonal antibodies in direct agglutination test and in gel is the most effective serological method of the antigen variants detection. Red blood cells with weak RhD antigens can be recognized by weakness or absence of agglutination with monoclonal antibodies on plane if agglutination in gel was 3+4+.Conclusion. Concrete weak RhD variants can be determined only by genetic typing. Serologically weak antigen variants can be detected by using of at least two series of monoclonal antibodies or by using of two different methods (it is preferable).

Cell Surface Glycoconjugates

Cell surface glycoconjugates are considered to play important roles in cell-cell interactions in the developing central nervous system. We have previously described a group of monoclonal antibodies that recognize defined carbohydrate epitopes and reveal unique temporal and spatial patterns of immunoreactivity in the developing main and accessory olfactory systems in rats. Antibody CC2 reacts with complex α-galactosyl and α-fucosyl glycoproteins and glycolipids. Antibody CC1 reacts with terminal N-acetyl galactosamine residues of globoside-like glycolipids. Antibody 1B2 reacts with β-galactosyl glycolipids and glycoproteins. Our light microscopic data suggest that these antigens may be located on the surfaces of axons of the vomeronasal and olfactory nerves as well as on some of their target neurons in the main and accessory olfactory bulbs.

The major structural lesions of the human brain during aging and in Alzheimer disease (AD) are the neurofibrillary tangles (NFT) and the senile (neuritic) plaque. Although these fibrous alterations have been recognized by light microscopists for almost a century, detailed biochemical and morphological analysis of the lesions has been undertaken only recently. Because the intraneuronal deposits in the NFT and the plaque neurites and the extraneuronal amyloid cores of the plaques have a filamentous ultrastructure, the neuronal cytoskeleton has played a prominent role in most pathogenetic hypotheses.The approach of our laboratory toward elucidating the origin of plaques and tangles in AD has been two-fold: the use of analytical protein chemistry to purify and then characterize the pathological fibers comprising the tangles and plaques, and the use of certain monoclonal antibodies to neuronal cytoskeletal proteins that, despite high specificity, cross-react with NFT and thus implicate epitopes of these proteins as constituents of the tangles.
