The first selective inhibitor of protein kinase R- (PKR)-like endoplasmic reticulum kinase (PERK), GSK-2606414, has been shown to attenuate vascular remodeling in pulmonary arterial hypertension (PAH) in mice, according to a study reported in the January 26, 2021, edition of Science Signaling.
The Human Skin Cell Atlas, comprising transcriptomes of 528,253 single cells, shows that cellular processes involved in skin development in embryos are reactivated in inflammatory skin diseases. In addition to suggesting potential new drug targets for atopic dermatitis and psoriasis, the transcriptomes provide a new route to understanding other inflammatory diseases, and provide a template for culturing skin for wound repair, according to the authors of a paper published in the Jan. 22, 2021, issue of Science.
