The article demonstrates that in conditions of absence of antigen stimulation in venous blood percentage of promocytes made up 26% (20.0; 36.0), monocytes proper--40% (29.5; 47.0), polymorphic nuclear monocytes--31.0% (24.5; 43.0). The molecule of L-selectin was expressed by 42.2% of monocytes; of LFA-1--99.72%; of ICAM-1--88.88%; of LFA-3--94.11%; of PECAM-1--97.50% of monocytes. The positive correlation is established between content of polymorphic nuclear monocytes and level of expression of molecules of LFA-1, ICAM-1, LFA-3, and PECAM-1. This occurrence can testify readiness to implementation of phase of sliding, solid adhesion and transmigration immediately by polymorphic nuclear monocytes primarily.
