We feel something is lost for readers and authors in denying them the chance to freely speculate about the meaning and implication of their data. 💡 That’s why we’ve introduced an ‘Ideas and Speculation’ section in our articles. Find out more: buff.ly/1623cqp

Sleep-dependent clearance of brain lipids by peripheral blood cells - Nature
Peripheral macrophage-like haemocytes in Drosophila promote sleep by clearing lipid buildup in the brain, helping to maintain metabolic homeostasis and brain function and fitness.

Immune cells from the gut drive development of Parkinson’s disease in the brain
In ‘body-first’ Parkinson’s disease, misfolded proteins propagate from the gut’s nervous system to the brain. Immune-cell activity seems to play a key part in this spread.

Rewiring of cortical glucose metabolism fuels human brain cancer growth - Nature
The cortex fuels essential physiological processes with glucose-derived carbon, while gliomas fuel their aggressiveness by rerouting glucose carbon pathways and scavenging alternative carbon sources such as environmental amino acids, providing a potential therapeutic target.

Now online! RNA innate immunity constitutes a barrier for interspecies chimerism

RNA innate immunity constitutes a barrier for interspecies chimerism
Interspecies PSC co-culture induces horizontal RNA transfer that activates innate immunity in “winner” mouse cells, a response that is alleviated by Mavs deletion, thereby enhancing “loser” human PSC survival and chimerism.

How does the #tumor #microenvironment modulate sensitivity to nutrient restriction? @chengflylab.bsky.social &co show that this is regulated by the SCL36 amino acid transporter Pathetic at the #BloodBrainBarrier perineural glial cells in #Drosophila #brain tumors @plosbiology.org 🧪 plos.io/4ibwXWY
Left: Maximum projection images of elavC155QF>QUAS-prosRi tumor brains stained with Repo and Dpn. The animals were moved from standard food to chemically defined diet (CDD) (top left), CDD minus Leu (top right), CDD minus Ile (bottom left), and CDD minus Met (bottom right) at 72hALH and dissected at 120hALH. Right: Schematic depicting the working model. Nutrient Restriction (NR) inhibits BBB glia expansion, which consequently limits brain tumor growth. The authors show that NR inhibits the expression of fat body and glia-derived Ilp6, causing downregulation of the InR/PI3K pathway in BBB glia. This results in a reduction in Path expression and the downstream mTOR-S6K pathway, causing a slowdown of BBB glial cell cycle progression. Path downregulation and defects in BBB expansion consequently led to a decrease in brain AAs, such as Leu, which hinders brain tumor protein synthesis to slow down tumor growth. Data information: ALH, after larvae hatching.
