- 17Beta-estradiol increases Leishmania mexicana killing in macrophages from DBA/2 mice by enhancing production of nitric oxide but not pro-inflammatory cytokinesC M Lezama-Davila
Department of Microbiology, The Ohio State University, Columbus, Ohio 43210, USA
Am J Trop Med Hyg 76:1125-7. 2007..mexicana-infected male and female DBA/2 macrophages without increasing production of pro-inflammatory cytokines. These data indicate that E(2) may enhance leishmanicidal activity in macrophages by directly regulating production of NO...

- Role of phosphatidylinositol-3-kinase-gamma (PI3Kgamma)-mediated pathway in 17beta-estradiol-induced killing of L. mexicana in macrophages from C57BL/6 miceClaudio M Lezama-Davila
Department of Microbiology, The Ohio State University, Columbus, OH 43210, USA
Immunol Cell Biol 86:539-43. 2008..In addition, they suggest that PI3Kgamma is not required for E2-induced cytokine and NO production in L. mexicana-infected macrophages from female C57BL/6 mice but it may be involved in parasite clearance from these cells...
