Background & Objective: Coronavirus disease 2019 (COVID-19) is the most recent emerging viral disease. Defining the epidemiological aspects and factors influencing the susceptibility of the patients to COVID-19 has been an ongoing struggle. In the present study, we have investigated the connection between ABO histo-blood group phenotypes and the COVID-19. Methods:...
ABO histo-blood group antigens have been postulated to modify pathogen spread through the action of natural antibodies and complement. The antigens are generated by a polymorphic glycosyltransferase encoded by 2 dominant active and a recessive inactive allele. In this study we investigated whether ABO sugars are incorporated into the envelope of HIV-1 virions. HIV vectors derived from cells exp...
BACKGROUND AND AIMS ABO encodes a glycosyltranferase which determines the major human histo-blood group. The FUT2 fucosyltransferase allows expression of ABO antigens on the gastrointestinal mucosa and in bodily secretions (secretor phenotype). A nonsense allele in FUT2 represents a susceptibility variant for Crohn's disease, and both the secretor and ABO blood group status affect the compositi...

The ABO histo-blood group, first discovered over a century ago, is found not only in humans but also in many other primate species, with the same genetic variants maintained for at least 20 million years. Polymorphisms in ABO have been associated with susceptibility to a large number of human diseases, from gastric cancers to immune or artery diseases, but the adaptive phenotypes to which the p...
The ABO histo-blood group system is the most important antigen system in transplantation medicine, yet no small animal model of the ABO system exists. To determine the feasibility of developing a murine model, we previously subcloned the human alpha-1,2-fucosyltransferase (H-transferase, EC 2.4.1.69) cDNA and the human alpha-1,3-N-acetylgalactosaminyltransferase (A-transferase, EC 2.4.1.40) cDN...
Tumor progression is often associated with altered glycosylation of the cell-surface proteins and lipids. The peripheral part of these cell-surface glycoconjugates often carries carbohydrate structures related to the ABO and Lewis blood-group antigens. The expression of histo-blood-group antigens in normal human tissues is dependent on the type of differentiation of the epithelium. In most huma...
Background and objectives: Coronary heart disease (CHD) is a major cause of death and disability worldwide. This study designed to determine the correlation of ABO histo-blood groups with baldness and susceptibility to cardiac diseases in Baqubah city, Diyala province in Iraq .Patients and methods: In this cross sectional, hospital based case control study, 68 male were enrolled .Group (A) incl...
