From NIH's Zarate lab: a new study in Nature compared HNK, #psilocybin, LSD, and DOI in human stem cell-derived neurons. Despite hitting different receptors, all produced similar gene expression shifts, dipping at 6 hours then rebounding by 24 with increased synapse formation. Read the study:

A new The Philadelphia Inquirer investigation found that smoke shops in the Philadelphia area are selling unregulated #psychedelic products, and the results are alarming. Lab tests revealed fabricated safety reports, banned hallucinogens, and synthetic compounds with unknown health effects.

#UCDavisIPN Director @deolsonlab.bsky.social and Assoc. Director John Gray, are featured in a new @newyorker.com article exploring the science behind why mind-altering drugs (and non-hallucinogenic #psychedelic analogues) can have lasting therapeutic effects. Read the story here:

Why Do Mind-Altering Drugs Make People Feel Better?

Scientists want to redesign psychedelics so that they don’t induce a trip—but they still improve mental health.

#UCDavisIPN Affiliate Aijun Wang and his team released a new study in @acs.org - Nano highlighting how engineering simplified extracellular vesicle mimetics can help uncover which surface proteins actually drive neuroprotective effects. 1/2

Prototyping Minimal Extracellular Vesicle Mimetics Using Cell-Free Synthesis

The many surface proteins on extracellular vesicles (EVs) allow them to target recipient cells and modulate cellular responses. Despite their importance, relating surface protein and EV function is challenging due to surface protein heterogeneity. Here, we create a bottom-up, cell-free protein-synthesis platform to engineer artificial nanovesicles (ANVs) that display different EV surface protein domains. The platform is termed VESSEL (Vesicle Engineering Systems using Synthetic Expression and Loading). The surface proteins are selected based on proteomics data of native EVs from placental mesenchymal stem cells (PMSCs). To create VESSEL, we establish a protein anchor based on the bacteria membrane protein Aquaporin-Z. This anchor allows the flexible and cell-free protein synthesis of 39 different EV surface protein domains, each anchoring into more than 108 ANVs per μL. Furthermore, we measure the ANVs using high-fidelity assays, including single-ANV flow cytometry, super-resolution imaging, and vesicle-based ELISA. Next, we show the impact of each EV surface protein on cellular uptake. Specifically, we find that certain EV surface protein domains govern ANV uptake into HEK293FT cells, explaining the variable observations in the field. We discovered new proteins, such as CADM1 and NPTN, that mediate high-efficiency cellular uptake. Additionally, five proteins were selected for our neuroprotection assay, where three proteins were significant in increasing SH-SY5Y neurite growth. Our work demonstrates a high-throughput cell-free synthesis platform for studying surface proteins of EVs. It enables the systematic interrogation of EV’s function as “signalosomes” and facilitates the designing of well-defined EV mimetics to mediate cellular function.

New research in @pnas.org offers fresh insight into how brain connections are lost in #Alzheimer’s disease. The study finds that C4d, a molecule linked to the immune system, increases with age and Alzheimer’s, and can directly trigger the removal of synapses, the connections between neurons.
