The liver isn’t just passive “soil” for cancer spread – it’s an active partner. Understanding its immune-tolerant environment could unlock new therapies for colorectal cancer metastases, says @Maker_MD of @UCSFCancer and @UCSFSurgery. #Oncology #DDW2026 #LiverTwitter

Surgery is a "wicked" environment: feedback is delayed, noisy, and often biased. My essay on why experience doesn't always equal mastery, and how to learn when the feedback loops are broken.

❓ Why do T cells sometimes fail to fight cancer?

➡️ A new study in Nature shows that when T cells are exposed to cancer or long-term infections, they can enter a state called exhaustion, where they lose their ability to eliminate harmful cells.

➡️ The researchers found that exhausted T cells develop a special type of stress response. Instead of reducing protein production, these cells increase it, leading to protein buildup and overworked “chaperone” proteins. This stress weakens the T cells and helps tumors evade the immune system.

➡️ By blocking certain stress-related proteins, the scientists were able to restore T cell activity and improve the effectiveness of cancer immunotherapy in preclinical models.

🌟 Congratulations to my good friend and senior author Zihai Li of The Ohio State University Comprehensive Cancer Center and collaborators at Johns Hopkins, Emory, Uppsala University and others for advancing this important research. @Zihai @OhioState @HopkinsMedicine @EmoryUniversity

@RepGregMurphy We’ve got plenty of spots if you want to pick up your stethoscope. If you’re not going to do that, maybe make things a little easier for those of us that do instead of whatever this is.
