Leishmania donovani promastigotes evade the antimicrobial activity of neutrophil extracellular traps
Upon their recruitment to a site of infection and their subsequent activation, neutrophils release DNA and a subset of their granule content to form filamentous structures, known as neutrophil extracellular traps, which capture and kill microorganisms. In this study, we show that Leishmania promastigotes induced the rapid release of neutrophil extracellular traps from human neutrophils and were...
Research background. Lactic acid bacteria (LAB) are known to produce folate. However, this ability is highly strain-dependent. Folate synthesis in specific LAB strains affected by the availability of folate, which can be consumed other under certain conditions. Moreover, differences folate capabilities related presence biosynthesis-related genes and regulation pathway. Experimental approach. As...
BACKGROUND African trypanosomes are capable of both pyrimidine biosynthesis and salvage of preformed pyrimidines from the host, but it is unknown whether either process is essential to the parasite. METHODOLOGY/PRINCIPAL FINDINGS Pyrimidine requirements for growth were investigated using strictly pyrimidine-free media, with or without single added pyrimidine sources. Growth rates of wild-type...
Antimicrobial compounds have critical roles in plant immunity; for example, Arabidopsis thaliana and other crucifers deploy phytoalexins and glucosinolate derivatives in defense against pathogens. The pathogen-responsive MITOGEN-ACTIVATED PROTEIN KINASE3 (MPK3) and MPK6 have essential functions in the induction of camalexin, the major phytoalexin in Arabidopsis. In search of cyanide, a coproduc...
