Neuropathic Pain and Sensory Nerve Degeneration are Caused by Sensory Afferents
Author(s): Steve Jone*
Given the inadequate understanding of the biology of Parkinson's disease (PD), pain is a typical non-motor symptom. In this study, we demonstrate that peripheral administration of mouse α-synuclein (-Syn) preformed fibrils caused retrograde trans-synaptic spreading of Synpathology (pSer129) across sensory neurons and dorsal nerve roots, reaching central pain processing regions, including the spinal dorsal horn and the projections of the anterolateral system in the Central Nervous System (CNS). Reduced nerve conduction velocities (sensory and motor) and degeneration of small- and medium-sized myelinated fibres were cooccurring with impaired nociceptive response and pathological peripheral to CNS propagation of -Syn aggregates along interconnected neuronal populations within sensory afferents. Our findings indicate intriguing lines of inquiry into the processes driving pain in.. View More»
