Discovery to market is Canada's gap — great science, too little early capital. @UHN joining the Genesys University Seed Fund as a hospital partner helps close it, turning lab discoveries into companies, jobs and patient impact at home.

Early signals for a selective new immunotherapy: invikafusp alfa activates Vβ6/Vβ10 T cells in treatment-resistant solid tumours. START-001, in Nature Medicine, co-led at Princess Margaret by Dr Lillian Siu. Early, small numbers — larger studies needed.

New paper alert!! Here we show in patient blood samples and animal models that Doxorubicin directly rewires CD8 T-cells into “matrix remodeling T-cells” or “mx-Tcells”allowing them to stiffen cardiac collagen directly through a Lox dependent mechanism

Just published @Nature
A 3-agent AI personal health agent exceeded performance of a large language model/chatbot and serves as a foundation to build on for integrating sensor data, medical knowledge and coaching

In mammals, there is no damage accumulation, there is only impaired regeneration capacity.
One of the most interesting findings was a population of Arg1-positive macrophages.
These macrophages were activated in regenerating #young tissues but their activation was suppressed in #aged regenerating tissues.

山中因子とは違うRejuvenation因子の単離は色んな企業やアカデミアが実施していて、我々のOne Genomicsもこの論文のChurch博士と進めている
っていうのを色々書こうと思ったんだけど、Nature Agingって、インパクトファクター25もあるのね…。驚愕
最初16とかで、まぁそんなもんか、思ってたけど、これが商業の力か。

New preprint from the lab: "A Compact Regulatory Logic Governs Fibroblast Cell State Plasticity in Fibrosis". We integrated mouse and human epigenomic data to identify 280 fibroblast disease-activated enhancers, then perturbed them by CRISPRi CROP-seq. 🧵

An absolute pleasure to be with my better half at #CCC 2026 while she presented her work on heart failure discharge criteria and compliance.

Microplastics are chemically active, enable spontaneous •OH generation in water, and "have direct
implications for biomolecular adsorption, protein aggregation, and even cellular damage."

Aging clocks, here with metabolites, are remarkably predictive of future health outcomes (top graph) and are telling about an individual's lifestyle factors (bottom graph)

Our latest study suggests colchicine may improve LV recovery after acute myocarditis. Encouraging to see RCTs underway, including ARGO and CMP-MYTHiC, to establish its role. @Sukruth__K @_antocannata @Kings_BHFCentre #myocarditis ❤️🔥

It's late 2026 and we still don't have a way to assess a person's immune system status in the clinic, the underpinning of healthy aging. But soon there may be at least 3 ways!

Out now in Nature Medicine: a health-system-scale cachexia atlas (52K patients) that describes and predicts outcomes, with prospective risk models for lung, colorectal, and prostate cancer. Congrats to @EdReznik for a landmark paper for the field. nature.com/articles/s41591-0…

🧵 Biohub, @ENERGY, @NIH, and new funding partners today announced a major expansion of an international effort to generate and make accessible the data enabling predictive AI models of biology. Together, the organizations are investing $1.8 billion in funding, data, computation and new measurement technology - largest coordinated commitment to map the biology of the cell to power development of digital models of biology. bit.ly/3UhjoxD

A remarkable study of 12 million single-cells (RNAseq) from 8 cohorts plus proteomics to determine the immune cells linked to healthy aging. Major findings included:
—thymic involution is central (decline in naive T cells and thymic emigrants)
—elevated immune system activation, inflammaging
—CD8+ memory cells (GZMB+) high frequency
—CMV seropositivity and chronic disease

Delighted to share RNA fingerprinting, out today in @CellCellPress! Together with @david_a_knowles , we use Perturb-seq experiments—where the causal perturbation is known—to infer what drives cellular responses in new datasets: cell.com/cell/abstract/S0092…

Unfortunately, the medical community has a singular view of the basis of coronary artery disease—lipids. But we keep seeing ways that heart attacks can occur independent of any lipid abnormality, like this one
