Conotoxins: Therapeutic Potential and Application

open access: yesMarine Drugs, 2006
The pharmacological variety of conotoxins, diverse peptides found in the venoms of marine cone snails, is well recognized. Venoms from each of the estimated 500 species of cone snails contain 50 to 200 distinct biologically active peptides.

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

open access: yesEuropean 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 ...

Stapling Cysteine[2,4] Disulfide Bond of α-Conotoxin LsIA and Its Potential in Target Delivery

open access: yesMarine Drugs
α-Conotoxins, as selective nAChR antagonists, can be valuable tools for targeted drug delivery and fluorescent labeling, while conotoxin-drug or conotoxin-fluorescent conjugates through the disulfide bond are rarely reported.

α-Conotoxin Decontamination Protocol Evaluation: What Works and What Doesn’t

open access: yesToxins, 2017
Nine publically available biosafety protocols for safely handling conotoxin peptides were tested to evaluate their decontamination efficacy. Circular dichroism (CD) spectroscopy and mass spectrometry (MS) were used to assess the effect of each chemical ...

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

open access: yesCancer 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.

Constrained De Novo Sequencing of Conotoxins [PDF]

open access: yesJournal of Proteome Research, 2012
De novo peptide sequencing by mass spectrometry (MS) can determine the amino acid sequence of an unknown peptide without reference to a protein database. MS-based de novo sequencing assumes special importance in focused studies of families of biologically active peptides and proteins, such as hormones, toxins, and antibodies, for which amino acid ...

Transduction Mechanisms for Cold Temperature in Mouse Trigeminal and Vagal Ganglion Neurons Innervating Different Peripheral Organs

open access: yesActa Physiologica, Volume 241, Issue 11, November 2025.
ABSTRACT Aim To elucidate the molecular mechanism of cold sensing by visceral sensory endings, a side‐by‐side characterization of cold‐sensitive (CS) neurons in adult mouse trigeminal (TG) and vagal ganglia (VG) was performed. Methods A combination of physiological, pharmacological, molecular, and genetic tools was employed on trigeminal and vagal ...

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

open access: yesJournal 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.
