Chronicling changes in the somatosensory neurons after peripheral nerve injury

Abstract

In this work, cell-specific temporal changes that occur in DRG neurons after peripheral nerve injury were monitored. Altered responses of neurons to bradykinin, ATP, and acetylcholine were observed; three bradykinin responsive neuronal cell types appear that correlate with increased pain. The ability to temporally monitor cell-specific alterations in receptors and ion channels (termed as “Pigafetta Disease Chronicles”) should make it possible to uncover cell type-specific disease-relevant alterations in membrane macromolecules and potentially identify drug targets whose function is required to establish a pathological state. This opens up the possibility of designing novel therapeutic interventions that do not merely treat disease symptoms but prevent a pathological state altogether.
