Esterases are ubiquitous in nature and encompass a series of different enzymes acting upon select substrates. With the 91C kit, Naphthol AS-D Chloroacetate is enzymatically hydrolyzed by "specific esterase, " liberating a free naphthol compound. This then couples with a diazonium compound, forming highly colored deposits at sites of enzyme activity. This enzyme is usually considered specific for cells of granulocytic lineage. May be used to detect neutrophils in peripheral blood, bone marrow or tissue sections which have been paraffin embedded.

The neurotrophic cytokines ciliary neurotrophic factor and leukemia inhibitory factor (LIF) play a key role in neuronal and oligodendrocyte survival and as protective factors in neuroinflammation. To further elucidate the potential of endogenous LIF in modulating neuroinflammation, we studied myelin

Meprins are zinc-dependent metalloproteinases that are highly expressed in the brush-border membranes of both the kidney and the intestines. Meprins are capable of proteolytically degrading extracellular matrix proteins, proteolytically processing bioactive proteins, and play a role in inflammatory processes. In

Salicylate was recently shown to provide protection against cisplatin nephrotoxicity in rats. We have demonstrated that enhanced tumor necrosis factor-alpha (TNF-alpha) production mediates, in part, cisplatin nephrotoxicity. The purpose of this study was to determine if the protective effects of
