This phenotype is driven by inflammatory cues (TGF-β/GM-CSF) and enhanced by G-CSF priming—highlighting tissue-driven immune heterogeneity. Way to go, Team. Check out the paper here: pubmed.ncbi.nlm.nih.gov/42019709/

Latest from the Wysoczynski lab! In Experimental Hematology, Stephan et al. show that after MI, SiglecF⁺ neutrophils arise locally in the heart—not from immature cells, but from mature CD101⁺ neutrophils.

Several of the faculty and trainees from the center presented their latest cutting-edge cardiovascular research at last week's International Society for Heart Research-North American section meeting in Minnesota. It was a great meeting for all. #ISHRNAS2026 #cardiosky

Next on Sunday, Dr. Helen Collins will serve as a panel participant on the Early Career and Mid-Career Investigator Career Development Panel in the Lakeshore room between noon and 1 pm. This is a must for Trainees and fellow ECIs attending ISHR who would like advice on navigating academia.

First on Sunday morning, Drs. Helen Collins and Andrew Gibb will be moderating the oral presentations for the Early Career Investigator (ECI) Symposium Session in Lakeshore between 8 and 11. Come check out the session and the awesome lineup of 12 rising stars from the ECI community. #ISHRNAS #ECI

Headed to ISHR-NAS 2026 this weekend, several Center Faculty and Trainees will be attending and presenting.

Congratulations to Iona Palmer in the lab on our recent editorial in JACC-BTS www.jacc.org/doi/10.1016/... on the recent work by Ji and colleagues www.jacc.org/doi/10.1016/... #calciumhandling #ECC #heart

Congratulations to Dr. Jonah Stephan on defending his PhD yesterday! His dissertation on emergency granulopoiesis and wound healing after myocardial infarction is exactly the kind of mechanistic work that advances the field. We are proud that he trained in the Center. #CardioSky.

Dr. Wold presented new work from his laboratory examining the intergenerational impact of PM2.5 exposures and the effects of psychosocial stressors on cardiovascular physiology. @uoflenvirome.bsky.social @uoflmedicine.bsky.social

We are excited to host Dr. Loren Wold (pictured) from The Ohio State University, a leading expert on cardiac physiology and environmental toxicology, for today’s Environmental Medicine Grand Rounds.

Thanks to the @uoflmedicine.bsky.social for this highlight medicine.louisville.edu/news/univers...

Sign up now. Dont lose your spot at this premier cardiovascular science meeting #cardiosky ishrnorthamerican.org/meetings/

It is a great pleasure to introduce Dr. Caitlin Howard—AHA Predoctoral Fellow, macrophage mechanist, and incoming Northwestern postdoc with Prof. Elizabeth McNally. Dr. Howard (pictured) recently defended her PhD. Congratulations! #NewPhD #CardioSky #WomenInScience @stevenpjones.bsky.social

It’s graduation time at UofL. Avery Kendall will be walking across the stage for her Masters in Engineering. I cannot believe it’s my first time in the Yum Center. Beautiful choir.

Sign up before Monday to get the discounted hotel rates. I will be presenting some new data! But you won’t know or see it, if you are not there. Worth signing up for. #ISHRNAS2026

Congratulations to my student, Avery Kendall, on her presentation this afternoon. I have heard from multiple sources that you did an awesome job. I am proud of you! 👏 #APS2026 #APSSummit

I am incredibly thankful to the APS for selecting me for this incredible honor and for my mentors that nominated me and have supported me. I am thankful for the contributions of Dr. Guyton, whose work shaped integrative and systems level physiology. #APS2026 #APSSummit

Getting my metabolism fix now in this session at the Summit. #APS2026 #APSSummit

I stopped by the immunology session this morning. Some very interesting work being discussed in this space. I am always learning something new about the immune system! #APS2026 #APSSummit

Due to a scheduling conflict, I won’t be able to attend, so please support Avery and attend her first conference talk and snap pictures for me #APS2026 #APSSummit

Wow, such a great journey so far. It’s quite amazing to think that at my next Summit meeting, I will no longer be an Assistant Professor. I sure hope that I get to enjoy as much physiological research in my Associate Professor days as I have done thus far.

Enjoyed a lovely evening with several of the Centers trainees. We visited a lovely Italian restaurant. #APS2026 #APSSummit

Catching up with Srikanth and Charles Thodeti at the poster session at the Summit #APS2026 #APSSummit
