The eosinophil and its role in pathology
With the attraction of domestic and foreign literature data, the modern ideas about the role of eosinophilic granulocytes in the pathogenesis of diseases of infectious and noninfectious nature are emphasized in the review. The appearance of the new fundamental knowledge about the structural and functional potential of eosinophils orients the researches towards the possible involvement of these unique cells in the mechanisms of implementation of many pathological processes. Eosinophils are multifunctional leukocytes possessing a wide array of cytotoxic and immunoregulatory factors the action of which, on the one hand, is aimed to fighting the pathogen and on the other hand, can be implemented with regard to «healthy» body tissues causing their damage and dysfunction.
