Streptococcus pneumoniae is a common human pathogen and a major causal agent of life-threatening infections that can either be respiratory or non-respiratory. It is well known that the Helix pomatia (edible snail) agglutinin (HPA) lectin shows specificity for terminal αGalNAc residues present, among other locations, in the Forssman pentasaccharide (αGalNAc1→3βGalNAc1→3αGal1→4βGal1→4βGlc). Based...

We studied the lymphomatous cells of 39 children presenting with the classical features of malignant lymphoma. Twenty-two had T lymphoblasts. We could classify these patients into three subsets: The T lymphoblasts from children group 1 displayed antigen(s) shared by a thymocyte subpopulation, had terminal deoxynucleotidyl transferase (TDT), but no affinity for peanut agglutinin (PNA). The T lym...

The sulfated glycosaminoglycans, such as keratan sulfate and chitin sulfate having 3-hydroxy free N-acetyl-beta-D-glucosaminyl residues as constituents, reacted with wheat germ agglutinin and Solanum tuberosum agglutinin by sugar-specific interaction. The glycosaminoglycans showed different inhibitory activities to the hemagglutination reaction of these lectins and keratan sulfate and its modif...

Cold agglutinin disease is a rare autoimmune hemolytic anemia characterized by hemolysis that caused activation of the classic complement pathway. Sutimlimab, humanized monoclonal antibody, selectively targets C1s protein, C1 complex serine protease responsible for activating this

introduction autoimmune haemolytic anemia (aiha) is a complex process characterized by an immune reaction against red blood cell self-antigens. the analysis of specimens, drawn from patients with cold auto-immune hemolytic anemia is a difficult problem for automated hematology analyzer. this paper was written to alert technologists and pathologists to the presence of cold agglutinins and its ef...

brucellosis is an endemic disease in our country. neurobrucellosis occurs in 5 to 10% of cases, and can present at any stage of of the disease. this study was undertaken to evaluate clinical, epidemiological and paraclinical aspects of brucellosis with and without neurological manifestations. data of 30 patients, 15 cases with nervous system involvement (neurobrucellosis) and 15 cases without n...

Soybean agglutinin (SBA) represents the anti-nutritional molecule in soybean. This agglutinates erythrocytes of several animal species. The specific binding SBA to glycoprotein c...

A bacterial agglutinin specific for strains of Streptococcus mutans was isolated from human saliva. Physiochemical analyses showed the agglutinin to be a glycoprotein with a molecular weight of 60,000. The agglutinin aggregated four of the eight strains of Streptococcus mutans tested but did not aggregate the strains of Streptococcus salivarius, Streptococcus sanguis, and Streptococcus mitis te...

BACKGROUND Gc protein has been reported to be a precursor of Gc protein-derived macrophage activation factor (GcMAF) in the inflammation-primed macrophage activation cascade. An inducible beta-galactosidase of B cells and neuraminidase of T cells convert Gc protein to GcMAF. MATERIALS AND METHODS Gc protein from human serum was purified using 25(OH)D3 affinity column chromatography and modifi...
