Our new review on "Photobehaviours guided by simple photoreceptor systems" has been published (as author accepted manuscript version).
A synthesis, classification and hopefully a valuable resource, together with Emelie Brodrick.
Also with practical guidelines on how to measure photobehaviour.

RT by @physorg_com: Promising stem cell approach to correct #photoreceptor cell degeneration, which causes visual decline and blindness @dukenus https://linkinghub.elsevier.com/retrieve/pii/S152500162200716X https://medicalxpress.com/news/2023-04-stem-cell-approach-photoreceptor-degeneration.html

To identify the #neuronal mechanisms, Luis carried out #calcium #imaging experiments and found that the brain ciliary #photoreceptor cells showed graded activation by pressure stimuli.

Satoh &co from Hiroshima University describe a new and unexpected role for neuronal Synaptobrevin; read more in our Research highlight: https://journals.biologists.com/jcs/article/135/24/e135_e2401/286118/A-new-role-for-neuronal-Synaptobrevin

A study finds a cellular compartment for cold sensing in plants using genetically regulated localization of the blue-light #photoreceptor phototropin in liverwort. In PNAS Nexus: https://academic.oup.com/pnasnexus/article/1/2/pgac030/6561641

As a result, discs cannot form and are instead shed as #extracellularvesicles, causing #photoreceptor death and sight loss. Excitingly, pharmacological targeting of the actin skeleton can reduce the number of shed vesicles. /5

Collaborating with Wensel lab (Baylor College of Medicine)
and Machesky lab (CRUK Beatson Institute) we used in vivo #cryoET, advanced #LiveImaging, novel reporter #mice & humanised disease mouse models to show how #photoreceptor discs are formed and why #IRD patients lose their sight when this goes wrong. /2
