Host defenses in murine malaria: analysis of plasmodial infection-caused defects in macrophage microbicidal capacities.

abstract：:Macrophages are among the most sensitive targets of bacterial endotoxin (LPS), responding to minute amounts of LPS by releasing a battery of inflammatory mediators. Transfection of macrophages with secretory leukocyte protease inhibitor (SLPI) renders these cells refractory to LPS stimulation. Here we show that uptake...
