Delighted to share our new Nature paper: rdcu.be/dNlMQ
This works shows a surprising off-target effect of glutamate on another cell death channel, acid sensing ion channels (ASICs). It turns out that glutamate directly binds to ASICs as a positive allosteric modulator
Amazing findings !!
Congrats you and the team

So for those of you interested in what it was that I took issue with in Hubermans first cannabis podcast, this is the Coles notes of the errors/inaccuracies that I noted. A lot of this is covered in the new episode, but some wont make it through and for others this is the TLDR
New Huberman Lab podcast out now:
CANNABIS: EFFECTS ON HEALTH & RISKS w/guest @canna_brain
•THC, CBD Biology
•Cannabis & Psychosis
•Is THC addictive?
•Are Strain Differences Real or Placebo?
•Appetite, Hormones
•Dosage Control: Inhaled vs Edible

Love cellular and molecular neuro. We are hiring a staff scientist interested in building framework of molecular principles for accurate sound information encoding and contribution to auditory deficits.

Must have background in patch clamp

Big news. We are moving.
I have officially started as the Director of the Gene Therapy Center, and as a Professor of Pediatrics and Professor of Pharmacology at UNC-Chapel Hill. I am returning “home” to lead the Center where I earned my PhD.
Amazing paper!!! Congratulations to you and John and the team.
Check it out: most beautiful images of vATPase with a surprising partner on live synaptic vesicles from my brilliant colleague John Rubinstein and his team at SickKids Reaearch Institute & University of Toronto!

Using a “humanized” hCD46 mouse model, we demonstrate these Ad vectors transduce cerebellar cell-types, including Purkinje cells, that are refractory to Ad5 transduction.
We thank @FamilieSCN2A @scn2agene @cacna1a @ncats_nih_gov @NIH_NINDS @NIDCD @uihealthcare @uiowaOUR funding this research We thank @UIowaACB @UIowaNeuro @UIowaResearch for creating an amazing environment for carrying out high risk high reward research
Finally, I want to thank Dr. Emre Kul, Uchechi Okorafor @MissSafie and the rest of the team for taking on this immense challenge to solve a fundamental problem in the gene therapy field.
However, these Ad5 vectors are unable to transduce many neuronal cell types that are dysfunctional in many CNS disorders. The human CD46 (hCD46) receptor is widely expressed throughout the human CNS and is the primary attachment receptor for many Ad serotypes.
Viral vector gene therapy has immense promise for treating central nervous system (CNS) disorders. Although adeno-associated virus vectors (AAV) have had success, their small packaging capacity limit their utility to treat the root cause of many CNS disorders.
For ~25 years Ad vectors had little to no ability to transduce Purkinje cells, until now! Excited to announce our paper in MTMCD @MolTherapy on the development of Ad vectors that transduce Purkinje cells in a humanized mouse model shorturl.at/wyBW5
The CaV2.1 α1 subunit domain II–III loop and cytoplasmic C-terminus are positive regulators of presynaptic CaV2.1 abundance but do not regulate preference.
Presynaptic CaV2 subtype abundance regulates neuronal circuit properties, although the mechanisms regulating presynaptic CaV2 subtype abundance and preference remain enigmatic.
