About

The study of proinflammatory and anti-inflammatory cytokines and chemokines expression profiles in human monocytes to identify new effective biomarkers that have the best diagnostic potential in asymptomatic atherosclerosis.

Full description

This project is the first step in creating a method for assessing an individual activity of macrophages. The problems addressed in the project are socially significant because of the high incidence of life-threatening diseases and their effects in the population. The method of evaluation of monocyte-macrophages activity in human blood will be based on the analysis of expression of cytokines and chemokines - markers of inflammatory and anti-inflammatory activity of macrophages. The most informative panel of cytokines and chemokines obtained during the project can be further used to create effective diagnostic tests.
