TMEM16A Activation Inhibits Autophagy in Dorsal Root Ganglion Cells, Which is Associated with the p38 MAPK/mTOR Pathway.

Transmembrane member 16A (TMEM16A) exhibits a negative correlation with autophagy, though the underlying mechanism remains elusive. This study investigates the mechanism between TMEM16A and autophagy by inducing autophagy in DRG neuronal […]

N-methyl-D-aspartate receptor activation is downstream coupled to pannexin 1 opening by Src kinase in dorsal horn neurons: an essential link for mechanical hyperalgesia in nerve-injured rats.

A well-recognized molecular entity involved in pain-related neuroplasticity is the N-methyl-D-aspartate receptor (NMDAR), which is crucial for developing chronic pain. Likewise, the pannexin 1 (Panx1) channel has been described as […]

Targeting Na,K-ATPase-Src signaling to normalize cerebral blood flow in a murine model of familial hemiplegic migraine.

Familial hemiplegic migraine type 2 (FHM2) is linked to Na,K-ATPase α isoform mutations, including that of G301R. Mice heterozygous for this mutation () show cerebrovascular hypercontractility associated with amplified Src […]

The paracetamol metabolite N-acetyl-4-benzoquinoneimine (NAPQI) prevents modulation of K7 channels via G-protein coupled receptors by interference with PIP and Ca sensitivity.

Paracetamol has been found to alleviate inflammatory pain by modulating K7 channels. Its metabolite N-acetyl-4-benzoquinoneimine (NAPQI) increases currents through these channels via a stretch of three cysteine residues in the […]
