We study presynaptic function and dysfunction, specifically how neurotransmission is sustained during neuronal activity.

Huge thanks to @hantan98.bsky.social for completing the work started by Andrew and Robyn many moons ago!! Many thanks also to CHDI for funding!

Excess ADBE was conserved across all cell types examined and intriguingly was due to huntingtin haploinsufficiency, rather than a toxic gain of function of mutant huntingtin.

β€’ We are delighted to contribute to this work just out in @jneurochem.bsky.social, where we collaborate with the BlueSkyless Smillie lab to reveal that Huntington’s Disease model neurons display excess activity-dependent bulk endocytosis (ADBE).

Nanobinders for Synaptotagmin 1 enable the analysis of synaptic vesicle dynamics in rodent and human models. Synaptic neurotransmission is a critical hallmark of brain activity and one of the first processes to be affected in neural diseases. Monitoring this process, and in particular synaptic vesicle recycl...

Excited for our latest work! We developed nanobinders for the luminal domain of Synaptotagmin 1 (calcium sensor for synaptic vesicles). Thanks among others to @verstrekenlab.bsky.social @opazo.bsky.social @meunierlab.bsky.social @volkerhaucke-lab.bsky.social www.biorxiv.org/content/10.1...

These models have mutations in genes exclusive to either the pre- or postsynapse, suggesting ADBE is a presynaptic homeostatic mechanism that corrects for intrinsic dysfunction in ASD neurons.

Convergent depression of activity-dependent bulk endocytosis in rodent models of autism spectrum disorder

Our latest paper is out in Molecular Autism! We reveal that in neurons from five independent rat models of monogenic Autism Spectrum Disorder (ASD), activity-dependent endocytosis (ADBE) is selectively depressed, with no other synaptic vesicle recycling phenotype. Link to paper - rdcu.be/eh4Qa

πŸŽ‰ Congrats to Sabrin Haddad - winner of the 2024 JNC Young Scientist Paper of the Year Award (in honor of Mark A. Smith)!

Her paper reveals how a CACNA2D2 mutation disrupts calcium channel & synaptic function in encephalopathy.
