| Abstract: | The data on the state of cell-mediated immunity in patients with AIDS-related complex are presented. The synthetic peptide of membrane protein gp120 of HIV-1 was shown to inhibit leukocyte adhesion in persons under examination, as well as to have the tendency towards inhibiting the chemotaxis of migratory cells. The maximum effect was achieved at a peptide concentration of 10(-6) M. The data obtained in this investigation suggest the presence of specific cell-mediated sensitization to the fragment of protein gp120, detected by the adhesion inhibition test with the use of spectrophotometric techniques and the capillary evaluation of the chemotaxis of migrating cells, in patients with AIDS-related complex. |
