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