Traveling Metabolic Waves In Oxidant Release By Living 
 	Neutrophils, PNAS
 









Excerpts: Cell metabolism
 self-organizes into two types of dissipative structures: chemical oscillations
	and traveling metabolic waves. In the present study we test the hypothesis
	that traveling NAD(P)H waves within neutrophils are associated spatially and
	temporally with the release of reactive oxygen metabolites (ROMs). (...)
 Propagating NAD(P)H waves allow neutrophils to specifically deliver substrate
 to the lamellipodium at high concentrations, thus facilitating the local and
	periodic release of ROMs in the direction of cell movement and/or a
target.
