New protective antigen of group A streptococci.
It is widely believed that the surface M protein of group A streptococci is the predominant surface protein of these organisms containing opsonic epitopes. In the present study, we identified a new surface protein, distinct from M protein, that evokes protective antibodies. A type 18 M-negative mutant was found to be both resistant to phagocytosis in human blood and virulent in mice. The wild-t...
متن کاملSuppressed expression of blood group B antigen and blood group galactosyltransferase in a preleukemic subject.
The B antigen activity was severely diminished in a patient's RBCs at the preleukemic stage prior to chemo- or radiotherapy. The amount of H sites of the patient's RBC membranes was found to be comparable to that of O RBC membranes. The activity of alpha (1----2) fucosyltransferase (H enzyme) was not severely decreased in the patient's plasma and bone marrow. However, the activity of alpha (1--...
متن کاملCarcinoembryonic Antigen and Blood Group Substances1
Immunochemical studies support the view that carcinoembryonic antigens from entodermally derived adenocarcinomata are incomplete blood group substances of the ABO system. The deficient antigens have a tumor-specific activity, due to unmasking of a structural sequence that is cryptic in the normal situation. Two other serological activities of the tumor antigens are determined by ./V-acetylgalac...
متن کاملINRA, a new high-frequency antigen in the INDIAN (IN023) blood group system
BACKGROUND The INDIAN blood group system comprises 4 antigens sensitive to enzymes and 2-aminoethyl isothiouronium bromide (AET). AIM The patient's antibody was investigated for its specificity to the high-frequency antigens (HFA) of this system. MATERIAL AND METHODS Low ionic strength solution (LISS)-tube/LISS-indirect antiglobulin test (IAT) methods were used. The patient's red blood cell...
متن کاملThe Tall Tale of the Helicobacter pylori Blood Group Antigen Binding Proteins
The features of Helicobacter pylori adhesins, their interactions with their host counterparts, regulated and selective gene expressions are amongst the many clever strategies this microorganism undertakes to survive the otherwise sterile gastric milieu. The ingenious crafting of these interactions and the respective host reactions govern, in part, an array of consequences ranging from asympto...
