摘要:Caloric restriction extends healthy lifespan in multiple species(1). Intermittent fasting, an alternative form of dietary restriction, is potentially more sustainable in humans, but its effectiveness remains largely unexplored(2-8). Identifying the most efficacious forms of dietary restriction is key for developing interventions to improve human health and longevity(9). Here we performed an extensive assessment of graded levels of caloric restriction (20% and 40%) and intermittent fasting (1 a...

摘要:Olfaction is a fundamental sensory modality that guides animal and human behaviour(1,2). However, the underlying neural processes of human olfaction are still poorly understood at the fundamental-that is, the single-neuron-level. Here we report recordings of single-neuron activity in the piriform cortex and medial temporal lobe in awake humans performing an odour rating and identification task. We identified odour-modulated neurons within the piriform cortex, amygdala, entorhinal cortex and hi...

摘要:T cells in jawed vertebrates comprise two lineages, alpha beta T cells and gamma delta T cells, defined by the antigen receptors they express-that is, alpha beta and gamma delta T cell receptors (TCRs), respectively. The two lineages have different immunological roles, requiring that gamma delta TCRs recognize more structurally diverse ligands1. Nevertheless, the receptors use shared CD3 subunits to initiate signalling. Whereas the structural organization of alpha beta TCRs is understood2,3, t...

摘要:The highly pathogenic avian influenza (HPAI) H5N1 virus clade 2.3.4.4b has caused the death of millions of domestic birds and thousands of wild birds in the USA since January 2022 (refs. 1-4). Throughout this outbreak, spillovers to mammals have been frequently documented5-12. Here we report spillover of the HPAI H5N1 virus to dairy cattle across several states in the USA. The affected cows displayed clinical signs encompassing decreased feed intake, altered faecal consistency, respiratory dis...
