That view best reconciles parthenolide's electrophilic chemistry with the need to explain apparently specific ADORA2A pathway modulation.\\n\\nThe decisive experiments are not broader efficacy studies but causal tests of A2A dependence: receptor rescue, knockout, and adenosine-tone measurements under stress conditions. If the phenotype survives fixed ADORA2A signaling, the entire framing of the gap needs to move away from receptor specificity.\"}",
