Type 2 diabetes is often considered a protein misfolding disease. But where are these toxic proteins found? 🤔

🚨In new work out today in @natmetabolism.nature.com, we show that mitochondrial protein misfolding (yes mitos🤯) leads to beta cell damage in T2D. 🚨 nature.com/articles/s42... 1/n

Mice lacking this amino acid lost 30% body weight www.nature.com/articles/d41... Am I missing something? Mice engineered to have a specific and severe defect in amino acid metabolism get sick and lose weight. Might the rush to find new weight loss targets be impairing our critical faculties ?

Be on the lookout for a new paper from the lab:

"iCLAP: A high-plex immunostaining with high sensitivity for co-detection of low-abundance antigens".

In this paper, we introduce ICLAP to detect and spatially map low-abundance proteins, such as senescence markers, in FFPE tissue sections.

STING mediates lysosomal quality control and recovery through its proton channel function and TFEB activation in lysosomal storage disorders
STING signaling in the innate immune system is well known for its role in the antiviral type I interferon response. Tang et al. find that STING acts as an immune sensor of lysosomal activity. When the lysosome becomes defective, STING is activated and exerts a dual function that induces both immune signaling and lysosomal biogenesis.
