S-D-lactoylglutathione in resting and activated human neutrophils.

Zymosan particles opsonised with human serum factors functionally activate human neutrophils and induce a substantial modification of the human neutrophil cytosolic glyoxalase system. The activity of glyoxalase I increases and the activity of glyoxalase II decreases by 20-40% of their resting cell activities during the initial 10 min of activation. The cellular concentration of the glyoxalase intermediate S-D-lactoylglutathione increases by ca. 100% of resting cell levels during this period. This modification may be related to the ability of S-D-lactoylglutathione to stimulate the assembly of microtubules.
