CD4 Co-Receptor Regulates Sex-Specific NK Cell Responses to Acute Infection.

Immunity to ( ) is sexually dimorphic in humans and mice, with females having higher morbidity and mortality during immune dysfunction and HIV-AIDS. The mechanisms underlying these sex differences are unclear. We investigated how a lack of CD4+ T cells (CD4 co-receptor KO) impacted survival in mice.

Robust inducible gene expression in intracellular .

Attenuated strains of the intracellular pathogen can deliver genetically encoded payloads inside tumor cells. preferentially accumulates and propagates inside immune-suppressed tumor microenvironments. To maximize the payload impact in tumors and minimize damage to healthy tissues, it is desirable to induce payload synthesis when bacteria are eliminated from the healthy tissues but are grown to high numbers intratumorally.

Intrinsic role of bacterial secretion systems in phylogenetic niche conservation of Bradyrhizobium spp.

Bradyrhizobium is a biologically important bacterial genus. Different Bradyrhizobium strains exhibit distinct niche selection like free living, root nodular and stem nodular. The present in-silico study was undertaken to identify the role of bacterial secretome in the phylogenetic niche conservation (PNC) of Bradyrhizobium sp.

Complete Comparison Display (CCD) evaluation of ethanol extracts of Centella asiatica and Withania somnifera shows that they can non-synergistically ameliorate biochemical and behavioural damages in MPTP induced Parkinson's model of mice.

Parkinson's disease remains as one of the most common debilitating neurodegenerative disorders. With the hopes of finding agents that can cure or reduce the pace of progression of the disease, we studied two traditional medicinal plants: Centella asiatica and Withania somnifera that have been explored in some recent studies. In agreement with the previous work on ethanol extracts of these two plants in mice model, we saw an improvement in oxidative stress profile as well as behavioral performance in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) induced Parkinson-like symptoms in Balb/c mice.
