I’m excited to share our work investigating the impact of iron deficiency on arterial endothelial function! biorxiv.org/content/10.648…

Excited to announce the final versions of my paper on the role of the internal elastic lamina in resistance arteries and my review on pannexins in the vasculature are out! Thank you to the co-authors for your great work! Links in 🧵

Grateful to be a part of this great work lead by Claire Ruddiman and @b_odonnell17

RESEARCH ARTICLE: Elastin Regulation of Vasoreactivity in Resistance Arteries @conn_pann_fun @Luke_Dunaway @miriamcortese ahajrnls.org/4iqBTas

Why travel to Denmark to collect samples from a giraffe's heart? @conn_pann_fun lab members Skylar Loeb and Luke Dunaway, PhD, made the trip to learn more about diastolic heart failure. Red more: cvrc.virginia.edu/cvrc-trainees-…

To wrap up this series, this year (2025) in a soon-to-be-published study, @astrecyte is revealing that microglia (rather than BAMs) maintain basal capillary tone through vasodilatory COX1 signaling. A pre-print is available here: researchsquare.com/article/rs-614….🤩#20YearsInVivoMGImaging

Headed to #APS2025! Two great talks tomorrow from the Isakson Lab in the MCS session. Wyatt Shug (8:30AM) will present on basophil-endothelial crosstalk, and Skylar Loeb (10:50AM) will present the novel identification and impact of hemoglobin-alpha in cardiac lymphatics.

Check out our latest paper reviewing the regulation of vascular tone! Big thanks to co authors @astrecyte @eyolab @conn_pann_fun onlinelibrary.wiley.com/doi/full/10.11…

@Luke_Dunaway, PhD, recently received an @American_Heart Career Development Award to study iron's role in chronic kidney disease. Luke is a postdoc in the Isakson Lab and member of our Cardiovascular Training Program. Congratulations! Read more: cvrc.virginia.edu/luke-dunaway-p…

I will resubmit this data in my K99 application Monday. I'm hopeful for a great score. If you are coming to the Gordon Glia meeting, please come to my talk Thursday evening! Finally, I'll be applying for faculty positions later in the year.

I am thrilled to announce that a preprint of my current work is up. You can find it here: assets-eu.researchsquare.com/files/rs-61491…. To state succinctly- we show that microglia localize to capillaries where they mediate capillary dilation via the enzymatic action of cyclooxygenase-1. 1/n

For those that are making the move, I’m now on 🦋 @lukedunaway.bsky.social. I’ll plan to keep both accounts active for now.

The abstract deadline is one week away!

The abstract deadline for the Nitric Oxide GRS/GRC is less than a month away! Nov 3: Deadline for abstract submission for consideration for an oral presentation. Nov 10: Publication of GRS program Jan 11: Deadline for registration @heuser_k @miriamcortese

Hey! That’s my sister! Check out her master’s thesis work where she is building models to predict coastline erosion and engineering natural shorelines which mitigate damage to key ecosystems.

Congrats to twitterless Skylar Loeb for rocking her Quals!

Currently taking Post-Doctoral application nominations to our T32 training grant

Fun paper by @melissa_luse describing how direct endothelial-adipocyte cell-cell contact with gap junctions influences adipose function
