Cercetătorii Universităţii Columbia au descoperit că neuronii periferici conţin o enzimă care acţionează împotriva durerii cronice. Durerea poate declanşa procesul de creare a unui "drog" endogen care blochează suferinţa cu ajutorul acestui "întrerupător" enzimatic. Astfel, ţinta terapiei antialgice a durerii nu mai este creierul, ci periferia sistemului nervos. În cazul unei inflamaţii, enzima PKG este activată şi opreşte celelalte procese care provoacă durerea, fără să ajungă însă în creier, ca analgezicele obişnuite. Astfel, s-ar putea evita atât riscul efectelor secundare, cât şi cel de dependenţă.
