Remodeling of Phenotype CD16 + CD11b + Neutrophilic Granulocytes in Acute Viral and Acute Bacterial Infections
Neutrophilic granulocytes (NGs) are very important cells of innate immunity that can very quickly realize antibacterial and antiviral defense. Until the present time, the phenomenon of different levels of presentations of membrane receptors CD16 and CD11b NG in normal and pathological conditions wasn’t studied. We had studied the population of CD16+CD11b+NG in two groups of patients with acute viral and acute bacterial infections in the models of acute bacterial tonsillitis (ABT) and acute viral tonsillitis-EBV infection (AEBVI), having the same clinical symptoms in early stages of the disease. Comparative analysis of the redistribution of equipment intensity of CD16 and CD11b has detected three subpopulations of CD16+CD11b+NG population—CD16brightCD11bbright, CD16brightCD11bdim, and CD16dimCD11bbright—in normal and pathological conditions. It was found that subpopulation CD16brightCD11bdimNG dominates in healthy individuals; subpopulation CD16brightCD11bbrightNG dominates in patients with acute viral infection; subpopulation CD16dimCD11bbrightNG dominates in patients with acute bacterial infections. We had demonstrated that the study of CD16+CD11b+NG subpopulations allows in early stage of diseases to diagnose acute viral and acute bacterial infections. Our studies have demonstrated the positive effects of eukaryotic DNA sodium salt on the negatively altered phenotype subpopulation CD16+CD11b+NG, in particular, through the remodeling of the expression of CD11b on NG membrane.
