When Macrophages Disappear, Skin Blood Vessels Age!
Check out our new study @nature.com that uncovers how the loss of capillary-associated macrophages with age blocks vessel repair and blood flow, revealing a new cellular trigger of tissue aging. #Aging #Immunology

Niche-specific dermal macrophage loss promotes skin capillary ageing - Nature
Capillary-associated macrophages are selectively lost over time, contributing to impaired vascular repair and reduced tissue perfusion in older mice.

I am so excited to share new work on a TE insertion that regulates iridescence in swordtails, led by fantastic grad student @nadiahaghani.bsky.social and with help from many coauthors! In a time that has been so difficult to navigate, this & other projects have kept my spirits up: shorturl.at/NE65A
Insertion of an invading retrovirus regulates a novel color trait in swordtail fish
For over a century, evolutionary biologists have been motivated to understand the mechanisms through which organisms adapt to their environments. Coloration and pigmentation are remarkably variable wi...

I’d given up on social media, but I was missing too many cool papers. Case in point: this incredible new study from @cagricevrim.bsky.social and @karalmckinley.bsky.social. Simply amazing!
Lab’s 1st preprint!
Menstruation is understudied due to societal taboos + a biological challenge: mice (a key system for research + drug discovery) don’t menstruate.
@cagricevrim.bsky.social made menstruating mice + used them to discover early events in menstruation.
He is on the job market!

I’m thrilled to share my postdoc work and the first paper from the McKinley Lab! 🎉

We built the first transgenic model of menstruation in mice.
We used it to uncover how the endometrium organizes and sheds during menstruation. 🧪

A fascinating new study in which the humble sugar glider makes a special appearance, helping a team led by @brainevodevo.bsky.social and @fennak.bsky.social uncover the evolutionary history of a group of inhibitory neurons. Check out this thread summarizing the main findings!
Our new manuscript, led by Emily Corrigan, examines inhibitory neuron diversity across approximately 160 million years of evolutionary divergence, as part of BRAIN Initiative Cell Atlas Network (BICAN) developing brain atlas package: www.nature.com/articles/s41...
Conservation and alteration of mammalian striatal interneurons - Nature
An analysis of cell-type diversity in brain samples from a variety of mammalian species, both during development and in adult animals, reveals that the TAC3 initial class of striatal interneurons is c...
