An optonanobody for reversible photoactivation of recombinant and native alpha;7 nicotinic

Maria Vangelatou, Kian Stenbolt, Sylvie Bay, Karima Medjebeur, Gabriel Aymé, Pierre J. Lafaye, Arnaud Blondel, Laurie Peverini, Alexandre Mourot, Pierre‐Jean Corringer

The paper introduces an optonanobody that reversibly photoactivates native alpha7 nicotinic receptors without genetic modification, demonstrating its effectiveness in Xenopus oocytes and hippocampal slices.

Mapping the molecular motions of 5-HT3 serotonin-gated channel by Voltage-Clamp Fluorometry

Laurie Peverini, Sophie Shi, Karima Medjebeur, Pierre‐Jean Corringer

This study uses voltage-clamp fluorometry to map conformational changes in the 5-HT3 serotonin-gated channel, linking them to electrophysiological states and agonist effects.

Short-chain mono-carboxylates as negative modulators of allosteric transitions in GLIC, and impact of a pre-β5 strand (Loop {Omega}) double mutation on crotonate, not butyrate effect.

Catherine Van Renterghem, Ákos Nemecz, Karima Medjebeur, Pierre‐Jean Corringer

The paper identifies a mutation in the pre-β5 strand of GLIC that changes crotonate from a negative to positive modulator, suggesting its role in coupling ligand binding to pore gating.
