The emergence of SARS-CoV in 2002 and SARS-CoV-2 in 2019 led to increased sampling of sarbecoviruses circulating in horseshoe bats. Employing phylogenetic inference while accounting for recombination of bat sarbecoviruses, we find that the ...

In humans, the detection and ultimately the perception of sweetness begin in the oral cavity, where taste receptor cells (TRCs) dedicated to sweet-sensing interact with sugars, artificial sweeteners, and other sweet-tasting chemicals. Human...
Long-term histone lactylation connects metabolic and epigenetic rewiring in innate immune memory [0.03%]
组蛋白乳酸化修饰连接代谢和表观遗传重编程促进先天免疫记忆形成

Trained immunity, a de facto innate immune memory characterized by enhanced responsiveness to future challenges, is underpinned by epigenetic and metabolic rewiring. In individuals vaccinated with Bacille Calmette-Guérin (BCG), lactate rel...
Snake venom protection by a cocktail of varespladib and broadly neutralizing human antibodies [0.03%]

The inhibitory receptor LAG3 is the target of the FDA-approved mAb relatlimab, but its mechanism of signaling is not well understood. In this issue of Cell, Jiang et al. demonstrate that ubiquitination of its cytoplasmic domain is essential...
Neural-activity-regulated and glia-mediated control of brain lymphatic development [0.03%]

Chemically modified nucleotides in mRNA are critical regulators of gene expression, primarily through interactions with reader proteins that bind to these modifications. Here, we present a mechanism by which the epitranscriptomic mark N6-me...
Global genetic structure of human gut microbiome species is related to geographic location and host health [0.03%]
人类肠道菌群的全球遗传结构与地理位置和宿主健康状况相关

The human gut harbors thousands of microbial species, each exhibiting significant inter-individual genetic variability. Although many studies have associated microbial relative abundances with human-health-related phenotypes, the substantia...
A natural gene on-off system confers field thermotolerance for grain quality and yield in rice [0.03%]
水稻田间高温抗性自然基因开关型调控系统创制优质高产新品种
