    Look it’s a pretty good day when you get promoted to full Professor, but it’s a MUCH better day when your friends get promoted too. One of the best parts of this job is the friends you make along the way. @uOttawaBMI @HeartInstitute

    Elated to be promoted to Associate Professor with tenure! And, when your friends get promoted at the same time, naturally celebrations are in order! 🥂 So lucky to have amazing mentors, trainees and colleagues @UOHIResearch @uOttawaBMI and be part of @uOttawaMed!

    We are excited to share our hot-off-the-press study uncovering how RIPK1, a pro-inflammatory regulator of inflammation & cell survival, is a genetic risk factor for obesity in humans. nature.com/articles/s4225… Here's what we found: 1/

    Check out my cell-fie! Those are my fibroblasts growing happily under the microscope. I donated a skin biopsy to optimize iPSCs (stem cells) for some cool upcoming projects (👀@ThaisCoutinhoMD ) They are pretty good-looking, if I do say so my cell-f. Ha! I’m here all night.

    I was fortunate enough to write this review article with the incomparable @LeahSusser, a PhD student in the #Rayhive lab. If you think, like we do, that macrophages really are the coolest kid in the class, check it out. 👇

    Hey do you like science? How about inflammation? Maybe aging? The heart? The brain? BOTH? If so, we are looking for awesome people to join our team. We have cool new projects starting, and we are looking for grad students and postdocs to join us! raynerlab.com #Rayvive

    Our study led by @MyAnhNguyen9 and Huy-Dung Hoang is hot off the press in @CircRes! 👇 Their creative approach shows that miR-223 in atherosclerotic macrophages controls its genes mostly via translational repression. This miRNA is a powerhouse 💪!!

    miR-223 promotes the anti-inflammatory phenotype & cholesterol efflux of macrophages. miR-223-/- in murine models yields atherogenesis, lipid-laden plaques, and increased inflammatory markers via broad translational effects. ahajournals.org/doi/abs/10.116… @CircRes by @KateyRayner

    Thank you all for your messages! I’m grateful to @CIHR_ICRH for the recognition and @HeartInstitute and @uOttawaMed for enabling me to do the research I love. But, it is the people in the #Rayhive who deserve all the credit for our research success. I am merely their cheerleader,

    The littles were so so excited for this day (despite the worried faces and fear of needles). On the right--live footage of the littlest one "kicking COVID right in the butt". Thank you, science. 🙏💉🩹

    I know I am biased but @Adilrasheed88 gave an outstanding talk about how cool the spleen is during atherosclerosis. And—he is recruiting for his brand spanking new lab so if you think the spleen is cool too, hit him up! #VascularDiscovery23
