We earlier demonstrated that nitric oxide (NO) is a fungicidal molecule against Sporothrix schenckii in vitro. In the present study we used mice deficient in inducible nitric oxide synthase (iNOS-/-) and C57BL/6 wild-type (WT) mice treated with Nomega-nitro-arginine (Nitro-Arg-treated mice), an NOS inhibitor, both defective in the production of reactive(More)
Lipoxins (LX) and 15-epi-LX are lipids with a potent inhibitory effect on angiogenesis, in different models in vivo and in vitro. ATL-1, a synthetic analog of 15-epi-LXA4, inhibits various actions stimulated by vascular endothelial growth factor (VEGF). However, LX actions on endothelial cells (EC) in tumor-related contexts are still unknown. Here, we(More)
Adhesive interactions play important roles in coordinating T cell migration and activation, which are mediated by binding of integrins to RGD motif found on extracellular matrix proteins. Disintegrins, isolated from snake venoms, contain the RGD sequence that confers selectivity to integrin interaction. We have investigated the ability of three(More)
