Fred Hutch is bringing the 🔥 to #STATMadness!
@SuYapeng and team uncovered how the sugar mannose supercharges T cells and boosts tumor control.

Two obstacles in #CancerImmunotherapy are tumor-infiltrating T cell exhaustion and mitochondrial dysfunction.
Drs. @SuYapeng & Philip Greenberg at @FredHutch & @UW identified the E3 ubiquitin ligase KLHL6 as a dual-negative regulator of both.
🔎 Abstract: https://t.co/DMc53M3U3W
This @Nature study (https://t.co/GIGAZHozCz) shows that loss of the ubiquitin ligase KLHL6 in Tex cells prevents TOX degradation, stabilizing exhaustion and mitochondrial dysfunction. Another case linking proteostasis to T cell exhaustion. Congrats to @HutchGreenberg, Guideng Li.
"Huge thanks to an amazing team, mentors, and collaborators at @fredhutch@FH_IRC and globally
📄 Nature: “The ubiquitin ligase KLHL6 drives resistance to CD8⁺ T cell dysfunction”

🚨 Excited to share our collaborative work in @Nature ! 🚨
We identify KLHL6, an E3 ubiquitin ligase, as a key regulator that protects CD8⁺ T cells from both exhaustion and mitochondrial dysfunction — two major barriers in cancer immunotherapy. https://t.co/BUevIoTuSg🧵👇
📌 Take-home message:
Targeting ubiquitin-mediated proteostasis can coordinate cell state and metabolism in T cells.
KLHL6 is a multifunctional, clinically actionable target for next-gen immunotherapy.
