Optical Control of Membrane Viscosity Modulates ER-to-Golgi Trafficking The lipid composition of cellular membranes is highly dynamic and undergoes continuous remodeling, affecting the biophysical properties critical to biological function. Here, we introduce an optical a...

Excited to share our new @pubs.acs.org paper! We engineered cells with ~10% photolipids in the ER membrane. This enabled optical control of membrane viscosity to study its impact on ER→Golgi protein transport. @dirktrauner.bsky.social @noemijimenezrojo.bsky.social

Photoactivatable Cyclometalated Ir(III) Compound Penetrates the Blood-Brain Barrier in 3D Spheroidal and Advanced 3D Organoid Models of Inherently Resistant and Aggressive Brain Tumors The blood-brain barrier represents a significant challenge in delivering anticancer drugs for glioblastoma treatment. The study investigates the potential of a series of octahedral photoactivatable cyclometalated iridium complexes (Ir1–Ir10) with the general formula [Ir(ttpy)(C∧N)Cl]PF6 as photoactivated therapy candidates for the treatment of this aggressive tumor. These complexes, which include the terdentate ligand 4′-(p-tolyl)-2,2′:6′,2″-terpyridine (ttpy), and a C∧N ligand based on the deprotonated 2-arylbenzimidazole backbone, were tested on human glioblastoma using 2D cell cultures and 3D spheroidal models, including a fusion system comprising cerebral organoids from nonmalignant human-induced pluripotent stem cells and spheroids derived from malignant brain cells. The iridium complexes catalyze NADH photooxidation and photogenerate 1O2 and/or •OH under blue light irradiation. Blood-brain barrier penetration was assessed using various in vitro models. The complex Ir4, containing deprotonated methyl 1-butyl-2-phenylbenzimidazolecarboxylate, shows promise for targeted therapy of resistant brain tumors when photoactivated with blue light. Ir4 induces rapid and sustained ROS-mediated cytotoxicity and selectively accumulates in tumor tissue. This suggests its potential for fluorescently guided-PDT cooperative resection of glioblastoma. Notably, Ir4 significantly reduces glioblastoma growth even under dark conditions compared to conventional Temozolomide treatment without affecting healthy brain tissue.

Glad to share our last studies in collaboration with Viktor Brabec.

Not just obesity: GLP-1 receptor agonists advance on addiction - Nature Biotechnology GLP-1 agonists may lessen alcohol, smoking and possibly drug addictions. Evidence from clinical trials remains sparse, but that is about to change.

Will the 'skinny jabs' become known as the 'buzz killers'? GLP-1 receptor agonists have curbed some people's #addictions to #alcohol, #smoking, #cocaine, or #opioids. Research is gaining real momentum. Just out in Nature Biotechnology @natbiotech.nature.com www.nature.com/articles/s41...
