🎉 First preprint from our lab! Regulatory T cells are selectively recruited to regenerating but not scarring mouse digit tips, driving macrophage-mediated bone remodeling essential for regrowth. A new axis of innate/adaptive immune cooperation in mammalian regeneration! #immunology #regeneration
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

3 great days at the SIC Summer School in Hornbæk with inspiring talks, short talks from young researchers, poster sessions, networking, and a trip to Esrum Abbey.
Thank you to all speakers, participants, organisers, and the LEO Foundation for supporting the summer school.
See you 24–26 May 2027.
Lim lab investigates: Helminth worm-infected mice give birth to pups with elevated anti-viral defenses in their lungs, leaving them more resistant to infection by respiratory viruses such as influenza and RSV. What causes these protective effects? molbio.princeton.edu/news/2026/wh...
A few days late, but I’m happy to post our recent publication on body-to-brain signaling regulation of memory in Nature Aging:
Selective Treg recruitment to bone remodeling niches is required for digit tip regeneration https://www.biorxiv.org/content/10.64898/2026.05.04.722813v1
