The mutant carrying a deletion in the ortholog of the Bacillus subtilis response regulator gene degU showed a clearly reduced virulence in mice, indicating that DegU is involved in the regulation of virulence-associated genes.

An overview on the currently available data and calls for a German Chagas surveillance are given and there is a large variation in the estimated numbers on the incidence of ChagAs.
The cell envelope stress response mediated by the LiaFSRLm three-component system of Listeria monocytogenes is controlled via the phosphatase activity of the bifunctional histidine kinase LiaSLm.

Analysis of the LiaSR orthologue of Listeria monocytogenes shows that activation of LiaSR(Lm) results in a remodelling of the cell envelope via the massive upregulation of membrane-associated and extracytoplasmic proteins in the presence of inducing stimuli.
Conditional Overexpression of Neuronal Nitric Oxide Synthase Is Cardioprotective in Ischemia/Reperfusion

It is proposed that conditional transgenic overexpression of nNOS resulted in myocardial protection after ischemia/reperfusion injury because of inhibition of mitochondrial function and a reduction in reactive oxygen species generation.
