Statins represent a class of drugs commonly prescribed for lowering cholesterol levels, thereby reducing the risk of atherosclerotic cardiovascular disease. While accumulating evidence indicates an increased risk of peripheral neuropathy with prolonged statin use in humans, in vivo animal studies revealed an anti-nociceptive effect of these drugs without fully elucidating the underlying mechanisms. Transient receptor potential (TRP) ion channels represent a major class of receptors that are expressed in the peripheral nervous system and are involved in pain signaling. Among these channels, TRP

Dorsal root ganglion (DRG) neurons are quintessential for peripheral pain transduction, a process mediated, among others, by certain members of the transient receptor potential (TRP) superfamily of ion channels. Among those, TRPA1, TRPV1, TRPM3 and TRPM8 have been linked to chronic pain and neuropathies. Tumor suppressor candidate 5 (Tusc5) plays a role in adipocyte function, but is also expressed in all major classes of DRG neurons. Tusc5 function in DRGs has not been investigated. We conducted Fura-2 calcium imaging and patch clamp experiments in cultured DRG neurons from knock-in Tusc5eGFP
