abstract：:Lipoxins (LX) are proresolving mediators that augment host defense against bacterial infection. Here, we investigated roles for LX in lung clearance of the fungal pathogen Cryptococcus neoformans (Cne). After intranasal inoculation of 5,000 CFU Cne, C57BL/6 and C.B-17 mice exhibited strain-dependent differences in Cne...
