Pharmacological Research, 2023 The pentameric nicotinic acetylcholine receptors (nAChRs) are typically classed as muscle- or neuronal-type, however, the latter has also been reported in non-neuronal cells.

Venom duct origins of prey capture and defensive conotoxins in piscivorous Conus striatus
Scientific Reports, 2021 The venom duct origins of predatory and defensive venoms has not been studied for hook-and-line fish hunting cone snails despite the pharmacological importance of their venoms. To better understand the biochemistry and evolution of injected predatory and

Interaction of α9α10 Nicotinic Receptors With Peptides and Proteins From Animal Venoms
Frontiers in Cellular Neuroscience, 2021 Unlike most neuronal nicotinic acetylcholine receptor (nAChR) subunits, α7, α9, and α10 subunits are able to form functional homo- or heteromeric receptors without any β subunits.

Molecular basis for a pore block of Tentonin 3 expressed in HEK293 cells by a conopeptide, NMB‐1
British Journal of Pharmacology, EarlyView.Background and Purpose Tentonin 3 (TTN3/TMEM150C) is a mechanosensitive ion channel that plays critical roles in mechanotransduction processes. TTN3 forms a tetramer with a predicted rectangular shape and a central pore. A conotoxin ρ‐TIA and its synthetic analog, noxious mechanosensation blocker 1 (NMB‐1), were initially developed to inhibit slowly ...

Experimental Physiology, EarlyView.Abstract Chronic visceral pain is a key symptom of irritable bowel syndrome. Modulation of voltage‐gated calcium and potassium channels by G protein‐coupled receptors plays a key role in dampening nociceptive transmission. Both baclofen and the analgesic peptide α‐conotoxin Vc1.1 activate GABAB receptors (GABABR), resulting in inhibition of CaV2.2 and ...

The Journal of Physiology, EarlyView.Abstract figure legend Left: the spontaneous quantal release of dopamine (DA) occurs at very low frequency in control conditions. Right: exogenous α‐synuclein potentiates Cav2.2 currents and DA release but drastically reduces the spontaneous firing rate of substantia nigra DA neurons.

Angewandte Chemie, Volume 137, Issue 27, July 1, 2025.Human synenkephalin [1–53] (hSYN), an analogue peptide of shrew saliva neurotoxins, was synthesized and its structural characteristics studied. Synthetic hSYN potently activated the T‐type voltage‐gated Ca channel hCav3.2 but did not paralyze mealworms. These findings offer new insight into neurological disorder treatment and evolutionary mechanisms of

MedComm, Volume 6, Issue 12, December 2025.Role of neurotransmitters in multiple pathological processes. Various neurotransmitters, including ACh, EPI, NE, 5‐HT, histamine, DA, glutamate, GABA, and neuropeptides participate in regulating key pathological events, including tumor proliferation, tumor migration, remodeling of the immune microenvironment, and the development of NDDs and ...
