In blood donors, if very weak expression of A or B antigens on the RBCs is not detected, the major risk is that they may be transfused to a patient whose antibodies may cause accelerated destruction of the transfused cells. Rare Bombay (Oh) phenotype RBCs, first reported in Bombay (...

1. Understand Blood Group Basics: Blood groups are determined by the presence of specific antigens on the surface of red blood cells and corresponding antibodies in the plasma. The main blood groups are A, B, AB, and O. 2. Identify Antigens and Antibodies: - Antigen A is present on ...
Tolerogenic hepatic APCs characteristically resist functional maturation in response to pathogen- or danger-associated molecular patterns (PAMPs; DAMPs), which are present physiologically in portal venous blood, through the development of hyporesponsiveness towards these stimuli or through non-responsiveness du...
Immunoperoxidase methods were used to study ABO(H) blood group antigens and carcinoembryonic antigens in patients with transitional cell carcinoma of the bladder. In our study absence of blood group antigens in cancer tissues was not found to be correlated with histologic grade, stage and survival...
