The Orange Cat Brain Atlas is here. 🧠🐈 Today, we published the first comprehensive cellular map of the orange cat brain. The new atlas reveals a single, specialized neuron responsible for behaviors like staring at walls, knocking objects off tables, and the 3am "zoomies."

Loss of MYO10-dependent mitochondrial transfer from satellite glia to sensory neurons emerges as a previously unrecognized driver of diabetic peripheral neuropathy. Really interesting article👏🏻👌🏻 www.nature.com/articles/s41...

Mitochondrial transfer from glia to neurons protects against peripheral neuropathy - Nature

Mitochondria that are transported from satellite glial cells in dorsal root ganglia to peripheral sensory neurons through tunneling nanotube-like structures provide protection against peripheral neuro...

Nature research paper: Integration of hunger and hormonal state gates infant-directed aggression go.nature.com/3WmxmvH

Integration of hunger and hormonal state gates infant-directed aggression - Nature

Combined behavioural, circuit-level and cellular approaches are used to demonstrate how hypothalamic neurons integrate hunger and oestrous state to drive a switch in how female mice interact with pups.

Nature research paper: Amygdala–liver signalling orchestrates glycaemic responses to stress go.nature.com/4m2rH8t

Amygdala–liver signalling orchestrates glycaemic responses to stress - Nature

Studies in mice show that acute stress activates hyperglycaemia via activation of a medial amygdala–ventral hypothalamic circuit that controls glucose metabolic responses in the liver, independently of adrenal and pancreatic hormones.

#NeuroImmunologyPower! Woolf &co show @nature.com that peripheral neuropathy associated with type 2 #diabetes is delayed by recruitment of galactin-3 producing #macrophages which delay terminal sensory axon degeneration! #ScienceSavesLives www.nature.com/articles/s41...

Macrophages protect against sensory axon loss in peripheral neuropathy - Nature

A study in a mouse model of obesity and prediabetes demonstrates that recruitment of macrophages to nerves has a protective role in diet-induced peripheral neuropathy.

A new #ScienceAdvances study in rats reveals neurobiological mechanisms that trigger placebo analgesia—which occurs when a pharmacologically ineffective treatment still produces pain relief. scim.ag/3CtSzxn

Opioidergic activation of the descending pain inhibitory system underlies placebo analgesia

The placebo effect can relieve pain by activating the brain’s pain inhibition system via endogenous opioidergic signals.

The liver and muscle secreted HFE2-protein maintains central nervous system blood vessel integrity - Nature Communications

Blood vessel integrity is critical to maintain brain health. Here, the authors show that both the liver and the muscles secrete HFE2, a protein that promotes blood vessel integrity in healthy animals ...

Sexually dimorphic dopaminergic circuits determine sex preference

Sociosexual preference is critical for reproduction and survival. However, neural mechanisms encoding social decisions on sex preference remain unclear. In this study, we show that both male and femal...

PIEZO-dependent mechanosensing is essential for intestinal stem cell fate decision and maintenance

Stem cells perceive and respond to biochemical and physical signals to maintain homeostasis. Yet, it remains unclear how stem cells sense mechanical signals from their niche in vivo. In this work, we ...

Can viruses cause food addiction? This fascinating study demonstrates that Microviridae bacteriophages can influence behavioural outcomes related to food addiction via tryptophan and tyrosine signalling pathways www.nature.com/articles/s42...

Microviridae bacteriophages influence behavioural hallmarks of food addiction via tryptophan and tyrosine signalling pathways - Nature Metabolism

Castells-Nobau et al. provide insight into how bacteriophages in the gut microbiome contribute to regulating food addiction by modulating tryptophan and tyrosine metabolism in the host.
