Staphylococcal lipase affects phagocytosis of Staphylococcus aureus by human granulocytes and monocytes.

The rate of immunological and non-immunological phagocytosis of staphylococci by lipase pre-treated human granulocytes and monocytes was compared. It was found that the effect of this enzyme on two types of cells is opposite. Lipase decreases phagocytosis by granulocytes and increases by monocytes.
