For a long time, the physiological activity of TRP ion channels and the response to various stimuli have been the focus of attention, and the physiological functions mediated by ion channels have subtle links with the occurrence of various diseases. Our group has been engaged in the study of ion channels. In recent years, the report rate of TRPA1, the only member of the TRPA subfamily in the newly described TRP channel, has been very high. TRPA1 channels are not only abundantly expressed in peptidergic nociceptors but are also found in many nonneuronal cell types and tissues, and through the regulation of Ca influx, various neuropeptides and signaling pathways are involved in the regulation of nerves, respiration, circulation, and various diseases and inflammation throughout the body. In this review, we mainly summarize the effects of TRPA1 on various systems in the body, which not only allows us to have a more systematic and comprehensive understanding of TRPA1 but also facilitates more in-depth research on it in the future.

Ferroptosis is a form of iron-dependent programmed cell death, which is distinct from apoptosis, necrosis, and autophagy. Mitochondria play a critical role in initiating and amplifying ferroptosis in cancer cells. Voltage-Dependent Anion Channel 1 (VDAC1) embedded in the mitochondrial outer membrane, exerts roles in regulation of ferroptosis.

The neuromuscular junction (NMJ) is the linchpin of nerve-evoked muscle contraction. Broadly, the function of the NMJ is to transduce nerve action potentials into muscle fiber action potentials (MFAPs). Efficient neuromuscular transmission requires both cholinergic signaling, responsible for generation of endplate potentials (EPPs), and excitation, the amplification of the EPP by postsynaptic voltage-gated sodium channels (Nav1.

Action potentials (spikes) are regenerated at each node of Ranvier during saltatory transmission along a myelinated axon. The high density of voltage-gated sodium channels required by nodes to reliably transmit spikes increases the risk of ectopic spike generation in the axon. Here we show that ectopic spiking is avoided because K1 channels prevent nodes from responding to slow depolarization; instead, axons respond selectively to rapid depolarization because K1 channels implement a high-pass filter.

The hypoglycemic effects of nateglinide (NTG) were examined in rats with acute peripheral inflammation (API) induced by carrageenan treatment, and the mechanisms accounting for altered hypoglycemic effects were investigated. NTG was administered through the femoral vein in control and API rats, and its plasma concentration profile was characterized. The time courses of the changes in plasma glucose and insulin levels were also examined.
