FPR2/ALX Signaling in Autoimmune Astrocytopathy
2026-08-14
The reference study identifies FPR2/ALX stimulation by Quin-C1 as an immunomodulatory strategy that limits AQP4-IgG- and complement-driven autoimmune astrocytopathy in mice. Its depletion and pathway-inhibition experiments implicate microglia, natural killer cells, and SYK-AKT signaling in the protective response, while also highlighting the need for validation beyond the animal model.

Decitabine Primes Progenitor Tex for PD-1 Blockade
2026-08-13
A 2023 Journal of Clinical Investigation study shows that low-dose decitabine can improve anti–PD-1 therapy by expanding CD8+ progenitor exhausted T cells rather than merely reactivating terminally exhausted cells. The work identifies sustained JunD and JNK/AP-1 activity as an important mechanistic link and offers a framework for evaluating epigenetic priming in tumor-immunology models.
