FAF2 is a bifunctional regulator of peroxisomal homeostasis and saturated lipid responses.

Exposure to saturated fatty acids (SFAs), such as palmitic acid, can lead to cellular metabolic dysfunction known as lipotoxicity. Although canonical adaptive metabolic processes like lipid storage or desaturation are known cellular responses to saturated fat exposure, the link between SFA metabolism and organellar biology remains an area of active inquiry. We performed a genome-wide CRISPR knockout screen in human epithelial cells to identify modulators of SFA toxicity.

Trehalose dimycolate inhibits phagosome maturation and promotes intracellular growth via noncanonical SNARE interaction.

Unlabelled: Mycobacterial cell envelopes are rich in unusual lipids and glycans that play key roles during infection and vaccination. The most abundant envelope glycolipid is trehalose dimycolate (TDM). TDM compromises the host response to mycobacterial species via multiple mechanisms, including inhibition of phagosome maturation.

Proinflammatory and cytotoxic CD38 HLA-DR effector memory CD8 T cells are peripherally expanded in human cardiac allograft vasculopathy.

Background: T cell mediated immunity is reported to play a pathogenic role in cardiac allograft vasculopathy (CAV) in heart transplant (HTx) patients. However, peripheral blood CD8 T cells have not been previously characterized in CAV. This study aimed to identify potentially pathogenic circulating CD8 T cell populations in high grade CAV patients using cellular indexing of transcriptomes and epitopes by sequencing (CITE-seq).

Effect of Antimicrobial Wipes on Hospital-Associated Bacterial and Fungal Strains.

Background: Healthcare-associated infections (HAI) caused by multidrug-resistant organisms have emerged as a significant global issue, posing substantial challenges to healthcare systems. Low- and intermediate-level disinfectants are extensively utilized for cleaning and disinfecting surfaces in hospitals to mitigate environmental transmission of HAI. Therefore, the need for more effective and environmentally safe disinfectants is increasing.

Trichostatin A promotes de novo shoot regeneration from Arabidopsis root explants via a cytokinin related pathway.

De novo shoot regeneration, characterized by the emergence of adventitious shoots from excised or damaged tissues or organs in vitro, is regulated by the complex interplay between genetic and epigenetic regulatory mechanisms. However, the specific effect of histone deacetylation on shoot regeneration remains poorly understood. This study investigated the effects of trichostatin A (TSA), a histone deacetylase inhibitor, on shoot regeneration in callus derived from root explants.
