Conopeptides [V11L;V16D]ArIB and RgIA4: Powerful Tools for the Identification of Novel Nicotinic Acetylcholine Receptors in Monocytes

Frontiers in Pharmacology, 2019
Venomous marine snails of the genus Conus employ small peptides to capture prey, mainly osteichthyes, mollusks, and worms. A subset of these peptides known as α-conotoxins, are antagonists of nicotinic acetylcholine receptors (nAChRs).

Nicotinic Receptors in the Medial Habenula to Interpeduncular Nucleus Pathway: Modulators of Reward, Aversion and Emotion

European Journal of Neuroscience, Volume 62, Issue 11, December 2025.
ABSTRACT The medial habenula–interpeduncular nucleus pathway is a highly conserved and densely innervated brain circuit known for its unique cholinergic transmission and exceptional expression of nicotinic acetylcholine receptors. This pathway plays a critical role in regulating motivational and emotional processes, particularly those related to ...

Nicotinic Acetylcholine Receptor Pathways in Cancer: From Psychiatric Clues to Therapeutic Opportunities

Cancer Reports, Volume 8, Issue 11, November 2025.
ABSTRACT Background The prevalence of cancer poses significant challenges to treatment, largely because of drug resistance along with other side effects. Current studies have been investigating the growth factors more than other biologic tumor features, such as neurobiologic features.

DiPTH‐Cystine and PTH‐Cysteine in Disulfide Bond Analysis Using Automated Edman Degradation

Journal of Peptide Science, Volume 31, Issue 10, October 2025.
The mystery of PTH‐cysteine and diPTH‐cystine in the analysis of disulfide bonds is solved. Both derivatives were synthesized and applied to Edman sequencing. A time‐efficient combined workflow applying Edman and MS/MS sequencing for a comprehensive analysis of the complex disulfide connectivity in peptides and proteins was developed.

Cloning, Synthesis and Functional Characterization of a Novel α-Conotoxin Lt1.3

Marine Drugs, 2018
α-Conotoxins (α-CTxs) are small peptides composed of 11 to 20 amino acid residues with two disulfide bridges. Most of them potently and selectively target nicotinic acetylcholine receptor (nAChR) subtypes, and a few were found to inhibit the GABAB ...

Ageing‐induced weakness of mouse NMJs is associated with reduced active zone density, synaptic event kinetics and presynaptic calcium entry

The Journal of Physiology, Volume 603, Issue 20, Page 6445-6465, October 15, 2025.
Abstract figure legend A summary of age‐related changes contributing to reduced neurotransmission in mouse neuromuscular junctions (NMJ). At 26 months, NMJs showed potentiation in short‐term plasticity compared to 4‐ or 30‐month‐old synapses, which is a proxy for reduced probability of release within individual AZs (dashed arrow). Compared to NMJs from

Contributions of synaptic energetic dysfunction by microtubule dynamics and microtubule‐based mitochondrial transport disorder to morphine tolerance

British Journal of Pharmacology, Volume 182, Issue 17, Page 4058-4079, September 2025.
Abstract Background and Purpose Morphine is among the most powerful analgesic, but its long‐term use can cause tolerance. Synaptic ATP supply is critical for maintaining synaptic transmission. Microtubule‐based mitochondrial transport ensures synaptic energy supply.
