Crosstalk Between Astrocytes and Inhibitory Neurons During Maturation: Emerging Mechanisms and Functional Implications In this review, we discuss the development and maturation of inhibitory neurons and astrocytes and how early developmental activity in the brain might promote the interactions between these cell type...

I’m sooo excited to share our latest article led by Steve Hill and Isabel Bravo-Ferrer
1- How does the vasculature communicate with astrocytes?
2- Is this communication dependent to what happens in the body.
3- Is it relevant to human diseases?

Really excited to announce that the Holt lab will be starting in January 2026 in the Center for Substance Use Research at Temple University Lewis Katz School of Medicine. Interested in the role of gene regulation, astrocytes, and addiction? I'm hiring at all positions-DM or email me! l-holt-lab.com

Thrilled to share our new paper @cp-cell.bsky.social:
“Microglia–astrocyte crosstalk regulates synapse remodeling via Wnt signaling.”

This work demonstrates the necessity of glia–glia communication and coordination during synapse remodeling.

Hello world!
We just released a thing! In this preprint we provide evidence questioning the ability of the axon initial segment to undergo rapid structural plasticity in intact neurons from mouse, rat, and human cortex.

Astrocyte networks span large swaths of brain The networks are plastic, connect brain regions that aren’t connected by neurons and may enable long-distance communication between astrocytes, a new preprint shows.

Astrocytes connect specific brain regions through plastic gap junctional networks https://www.biorxiv.org/content/10.1101/2025.07.18.665573v1

Excited to share the preprint for one of my postdoctoral projects in the Nestler lab 🥳

So grateful to the @wellcometrust.bsky.social for investing in me... believing in me. It's hard to believe in yourself sometimes. Science is going really well and I am thrilled to be back in the lab

Thrilled to announce that my lab is now open at Ohio State! We study astrocytes as gene therapy targets for brain repair after ischemic stroke and in vascular dementia, developing new viral tools along the way. If you're interesting in joining or collaborating, please reach out!

Spatiotemporal Analysis of Remyelination Reveals a Concerted Interferon-Responsive Glial State That Coordinates Immune Infiltration Remyelination, the process by which axons are re-encased in myelin after injury, is a critical step in restoring brain function, yet the dynamics from initial injury to repair remain poorly characteri...

How does the brain repair myelin after injury?

We mapped the full cellular choreography of white matter repair using snRNA-seq + Slide-seqv2, uncovering a type I interferon-driven glial program that recruits lymphocytes to promote remyelination.

The brain’s “stalwart sentinels” express an unexpected gene The astrocytes that cover the brain and spinal cord and protect it from intruders lack the signature star shape and have a distinct genetic marker.

A new study led by @philiphasel.bsky.social reveals the unique genetic profile of astrocytes that form the glia limitans superficialis (GLS), the thin layer of cells that covers the brain and spinal cord 🧠

The brain’s “stalwart sentinels” express an unexpected gene The astrocytes that cover the brain and spinal cord and protect it from intruders lack the signature star shape and have a distinct genetic marker.

The cell bodies of astrocytes, not their end-feet, make up the brain’s last line of defense, a new paper in Cell Reports confirms. The findings flip the standard picture of these “stalwart sentinels” of the brain.

🚨The first #preprint of the #FalconeLab is OUT!🥹🚨

We found that varicose-projection astrocytes are not a physiological type of #astrocytes but they are rather associated with neuropathology.
