Why do we stop smelling odors that linger? In our new @prxlife.bsky.social paper with @pfrancois.bsky.social, @gautamreddy.bsky.social, and Massimo Vergassola, we develop a manifold learning theory of this olfactory habituation process in fluctuating environments. 🔗 doi.org/10.1103/q62z... 🧵🔽
Schematic of the early olfactory circuit with local interneurons inhibiting projection neurons. Above local neurons, a simplified depiction of a curved background manifold with a new odor that has an orthogonal component to the manifold. The circuit receives a mixture of background and new odor (apple) and outputs the new odor only.

Engineering TCR-controlled fuzzy logic into CAR T cells enhances therapeutic specificity
Robot-assisted analysis and theoretical modeling of TCR/CAR crosstalk enable the design of adoptive T cell therapies that maximize anti-tumor activity and minimize toxicity in healthy tissues.

Delighted to share our herculean, collaborative paper, published online today in Cell ! In short, we circle from data to theory back to experiments to design a new anti-cancer immunotherapy. www.cell.com/cell/fulltex...
Graphical Abstract of our paper : 
Highlights
•
TCRs impact CARs across a continuum of antigens, from antagonism to enhancement
•
Modeling of TCR/CAR crosstalk reveals ternary fuzzy logic in dual receptor activation
•
Fuzzy logic produces an antagonism-enforced braking system (AEBS) in CAR T cells
•
AEBS CAR T cells eradicate tumors with minimal toxicity against healthy human tissue
