This week we covered key findings on cancer targeted and immunotherapy to mom's high-fat diet and microglia wiring!

PD-1 blockade drug holiday improves exhausted progenitor CD8 T cell (Tpex) reinvigoration by avoiding Tpex adaptive resistance

Summary

In an immuno-oncology plot twist worthy of a sci-fi reboot, long-term PD-1 blockade turns out to exhaust the exhausted T cells' progenitors like overtraining a quirky gym bro, but a strategic "drug holiday" lets them bounce back stronger with fresh Tpex energy and even teams up with CD22 co-blockade for extra drama.

Community Discussion

Posted by E. John Wherry (@EJohnWherry) highlighting new Tpex biology and potential clinical implications for intermittent dosing; drew quick praise and interest from immuno-oncologists like Christopher Garris (@csgarrix) and Goran Micevic (@gmicevic)

Maternal high-fat diet drives sex-specific microglia remodeling of serotonergic reward circuits

Summary

Mom's junk-food pregnancy remodels baby boy mouse brains like a mischievous microglia interior decorator gone wild—beefing up serotonin highways in the reward center for turbo-charged motivation, while girls dodge the dopamine drama entirely.

Community Discussion

Shared by neuroimmunologist John Lukens (@LukensJohnR) with eye-catching visuals; resonated strongly in neuroscience circles for its sex-specific insights linking maternal diet to lifelong behavior

Targeted extracellular degradation of LRP8 promotes ferroptosis in cancer cells

Summary

Biotech wizards craft sneaky bispecific "KineTACs" that hijack LRP8 (selenium delivery guy) for lysosomal trash disposal, starving cancer cells of their antioxidant armor and making ferroptosis the surprise party crasher they can't resist.

Community Discussion

Posted by James Olzmann (@OlzmannLab) celebrating the collaboration with Jim Wells' lab; praised for clever extracellular degradation strategy targeting ferroptosis resistance

Stromal Gasdermin D-mediated Pyroptosis Drives Maladaptive CD4⁺ T-cell Remodeling in Tet2-Deficient Hematopoiesis

Summary

In TET2-mutant bone marrow, stromal cells go full pyroptosis drama queen via Gasdermin D, recruiting quirky TFH-like CD4 T cells into a chaotic feed-forward loop that turbocharges myeloid disease—until you cut the CD40L gossip.

Community Discussion

Posted by Peng Ji (@PengJi_lab) highlighting the stromal-immune circuit; drew interest from hematology and inflammation researchers for new therapeutic angles in clonal hematopoiesis
