The effect of such immunomodulators as glucoaminylmuramyldipeptide, gamma-interferon and polyoxydonium on the functional activity of phagocytic cells of peripheral blood taken from 33 healthy donors was studied. The adhesion of these cells on the plastic surface, their spontaneous and induced luminol-dependent chemiluminescence, the activity of myeloperoxidase and acidic phosphatase and changes in the activity of enzymes after the in vitro stimulation of the cells, the results of the spontaneous and induced nitro blue tetrazolium test, chemotaxis of neutrophils and the content of nonenzymatic cation proteins in neutrophils were determined. The study revealed considerable differences in the effect produced by the above-mentioned immunomodulating preparations on some manifestations of the phagocyte reactiveness in the examined subjects. Only in 30.0% of cases similar in vitro sensitivity of cells to two or all three preparations was registered, and in 15.2% of cases no stimulating effect was noted. Peripheral blood neutrophils are supposed to have individual sensitivity to certain immunostimulators.
Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
