🔬 Postdoc @bristoluni 🇬🇧, using #zebrafish 🐠 to study wound healing & scarring for a @scarfreeworld | he/him/Dr https://orcid.org/0000-0002-2582-0238

Very happy to share this study from our group and colleagues now out in Science! We found that in zebrafish, before the immune system is mature, gut epithelial cells perform immune functions by producing the cytokine IL-22 to shape the microbiota to promote early life gut function #Zebrafish #Gut

IL-22 from enteroendocrine cells promotes early-life gut motility in zebrafish through the microbiota

The gut microbiota, immune system, and enteric nervous system interact to regulate adult gut physiology. However, the mechanisms establishing gut physiology during development remain unknown. We repor...

Excited to have started my new lab in Human Genetics at Pitt Public Health! We study wound healing in diabetes & aging using adult zebrafish. Check out this movie showing neutrophil dynamics after injury. Now recruiting research staff, grad students, and postdocs. DM me if interested.

Great article by @kordinglab.bsky.social‬ on "why causal knowledge is pragmatically possible". The best arguments for causation--& only one we need--is pragmatic. Here pragmatic isn't weak/subjective, but connected to actual goals, utility & outcomes in the world. medium.com/@kording/why...

When we observe the world, we note that events consistently follow one another. As David Hume famously argued in An Enquiry Concerning…

Can I ask you to share a PhD advert at Bristol Uni please? Rhomboid proteases play a role in neurons that is essential for life- but it is not characterised. Got a student interested in cell biology, electrophysiology and neurobiology? Send them our way! tinyurl.com/56f24f7c
