Abstract
Summary. A definitive role of tobacco smoking as a risk factor for development of chronic obstructive pulmonary diseases (COPD) is of no doubt today. We performed in vivo experimental modeling of COPD in mice of different genetic strains (С57 and Balb/c). We studied phenotypes of main cells of the innate immunity that are alveolar macrophages, and revealed genetic and age susceptibility to COPD in experimental animals. We showed that 1) there is a certain genetic susceptibility to hazardous exposition of tobacco smoke, probably, associated with proinflammatory М1 macrophage phenotype; 2) aging promotes transformation of macrophage phenotypes towards antiinflammatory М2 which is more expressed in mice macro-phages with baseline genetically determined М1 phenotype (mice strain С57), and 3) long-time exposition to tobacco smoke enhances age-dependent macrophage transformation aside М2 phenotype, that is also more expressed in mice macrophages with genetically determined М1 phenotype (С57).
