Comprehensive genomic insights into isolated from the faecal sample of a tuberculosis patient in India.

, formerly known as , is a motile Gram-negative, facultatively anaerobic bacterium with coccoid rod morphology. Although previously considered non-pathogenic, emerging case studies indicate its potential role in causing serious infections, including bacteraemia, meningitis, sepsis, and implant-associated infections. This study presents the first whole-genome sequence of of Indian origin, isolated from the stool sample of a tuberculosis patient undergoing treatment.

Vitamin D receptor signalling regulates the diet-driven metabolic shift during weaning.

Objective: Weaning in mammals is associated with a shift in the metabolism, driven by the differences in the macronutrient composition of milk and post-weaning diet. Milk has a higher fat content compared with the carbohydrate-enriched solid food. Malnutrition during this stage could affect this transition with long-term adverse effects.

The SET29 and SET7 proteins of Leishmania donovani exercise non-redundant convergent as well as collaborative functions in moderating the parasite's response to oxidative stress.

SET proteins are lysine methyltransferases. In investigating Leishmania donovani SET29, we found depletion of LdSET29 by two-thirds did not affect promastigote growth, nor alter the parasite's response to UV-induced or HU-induced stress, but made it more tolerant to HO-induced oxidizing environment. The deviant response to oxidative stress was coupled to lowered accumulation of reactive oxygen species, which was linked to enhanced scavenging activity.

Inherent metabolic preferences differentially regulate the sensitivity of Th1 and Th2 cells to ribosome-inhibiting antibiotics.

Mitochondrial translation is essential to maintain mitochondrial function and energy production. Mutations in genes associated with mitochondrial translation cause several developmental disorders, and immune dysfunction is observed in many such patients. Besides genetic mutations, several antibiotics targeting bacterial ribosomes are well-established to inhibit mitochondrial translation.

Single-cell transcriptomic and T cell antigen receptor analysis of human cytomegalovirus (hCMV)-specific memory T cells reveals effectors and pre-effectors of CD8- and CD4-cytotoxic T cells.

Latent human cytomegalovirus (hCMV) infection can pose a serious threat of reactivation and disease occurrence in immune-compromised individuals. Although T cells are at the core of the protective immune response to hCMV infection, a detailed characterization of different T cell subsets involved in hCMV immunity is lacking. Here, in an unbiased manner, we characterized over 8000 hCMV-reactive peripheral memory T cells isolated from seropositive human donors, at a single-cell resolution by analysing their single-cell transcriptomes paired with the T cell antigen receptor (TCR) repertoires.
