Abstract Aim: Researchers have made considerable efforts to determine the significance of particular ABO antigens to diseases susceptibility such as cancer and infections. O blood group people have a higher risk than other blood groups for catching cholera. Thus relationship between ABO blood groups and catching disease is unknown remained. The aim of this study is to determine the lymphocyte phenotypic profile in ABO blood groups.
Material and Methods: Peripheral blood samples collected from forty health male people with different ABO blood groups (each group=10). All of studied people were in 18-25 years old ranges and had a closely similar genetic background. The samples were studied using a FACSort flow cytometr for determination of CD3+T-lymphocytes phenotype and their subsets CD4+, CD8+ and Treg cells (CD4+/CD25+/Foxp3+), CD19+ B-lymphocytes and their subsets CD5+ and CD5‾ B cells.
Results: There were no significant differences in the frequency of examined lymphocyte subpopulations (CD8+ and Treg lymphocytes, and B- lymphocyte subsets) between the ABO blood groups. But, the CD4+ T lymphocytes percentage in B blood group was higher than other groups (p < /em>=0.05).
Conclusion: High frequency of CD4+T lymphocytes in B blood group may be reduced catching some disease such as bacterial and parasitic infections.
