Abstract
Study the effect of Vaxigrip split, Influvac subunit and Grippol plus immune-adjuvanted vaccines on the content of myeloid (mDC) and plasmacytoid (pDC) dendritic cells (DC) in blood of vaccinated healthy women. Materials andmethods. Blood of 30 healthy women aged 18-50 years was studied at days 7 and 30 after the vaccination. pDC (CD14+CD16-/CD85k(ILT3)-PE/ CD123-PC5) and mDC (CD14+CD-16-/CD85k(ILT3)-PE/CD33 -PC5) immune phenotyping was carried out using mAbs (Beckman Coulter, France) and flow cytometer Cytomix FC-500 (Beckman Coulter, USA). Use of unadjuvanted vaccines Vaxigrip and Influvac resulted in an increase of the numbers of mDC and pDC (p<0.05) in blood of the vaccinated only at day 7 of the observation. Grippol resulted in a more significant (2.2 - 3.6 times, p<0.05) increase of DC subpopulations (compared with unadjuvanted vaccines) at both day 7 and a month after the vaccination. Influenza vaccination activated innate effectors - the first component on the way of infection penetration - dendritic cells of both myeloid and lymphoid origin. Wherein, a more pronounced and prolonged effect of such activation is observed when immune-adjuvanted vaccine is used compared with subunit and split vaccines.
