Scientists just cracked the mystery of why cancer immunotherapy fails. “Unlike ordinary stress responses that slow protein production to help cells regain balance, TexPSR drives protein synthesis into overdrive. The result is a relentless buildup of misfolded proteins, stress granules, and toxic aggregates ¾ similar to the amyloid plaques seen in Alzheimer’s disease. This overload poisons the T cells, crippling their ability to attack tumors.”. Nature 01 Oct 2025.
