[The comparative characteristics of antibacterial properties of the peptides of the active site of GM-CSF, and substances delivered from supernatants of hematopoietic progenitor CD34+45- cells].

The antibacterial activity of synthetic peptides of the active site of GM-CSF and supernatants of CD34+45- hematopoietic progenitor cells has been investigated GM-CSF peptides and cell supernatants were found to possess pronounced antibacterial activity, at that a combination of these substances has a more pronounced activity in comparison with the single substances. Possible mechanisms of the identified effects of synthetic peptides and substances from the supernatants of CD34+5- cells are discussed.
