The Slick (Kcnt2) sodium-activated potassium (K(Na)) channel is a rapidly gating
and weakly voltage-dependent and sodium-dependent potassium channel with no
clearly defined physiological function. Within the dorsal root ganglia (DRGs), we
show Slick channels are exclusively expressed in small-sized and medium-sized
calcitonin gene-related peptide (CGRP)-containing DRG neurons, and a pool of
channels are localized to large dense-core vesicles (LDCV)-containing CGRP. We
stimulated DRG neurons for CGRP release and found Slick channels contained within
CGRP-positive LDCV translocated to the neuronal membrane. Behavioral studies in
Slick knockout (KO) mice indicated increased basal heat detection and exacerbated
thermal hyperalgesia compared with wild-type littermate controls during
neuropathic and chronic inflammatory pain. Electrophysiologic recordings of DRG
neurons from Slick KO mice revealed that Slick channels contribute to outward
current, propensity to fire action potentials (APs), and to AP properties. Our
data suggest that Slick channels restrain the excitability of CGRP-containing
neurons, diminishing pain behavior after inflammation and injury.
