The main objective of the present study was to find detergents that can maintain the functionality and stability of the Torpedo californica nicotinic acetylcholine receptor (Tc-nAChR). We examined the functionality, stability, and purity analysis of affinity-purified Tc-nAChR solubilized in detergents from the Cyclofos (CF) family [cyclofoscholine...

Since their discovery, nicotinic acetylcholine receptors (nAChRs) have been extensively studied to understand their function, as well as the consequence of alterations leading to disease states. Importantly, these receptors represent pharmacological targets to treat a number of neurological and neurodegenerative disorders. Nevertheless, their thera...
Article
Many pathogens, such as Pseudomonas aeruginosa and Escherichia coli bacteria can easily attach to surfaces and form stable biofilms. The formation of such biofilms in surfaces presents a problem in environmental, biomedical, and industrial processes, among many others. Aiming to provide a plausible solution to this issue, the anionic and hydrophobi...
Article
Over the past 10 years we have been developing a multi-attribute analytical platform that allows for the preparation of milligram amounts of functional, high-pure, and stable Torpedo (muscle-type) nAChR detergent complexes for crystallization purpose. In the present work, we have been able to significantly improve and optimize the purity and yield...

For a long time, traditional purification and extraction methods for the native Torpedo californica nicotinic acetylcholine receptor in lipid-like detergent complex (nAChR-DC) have compromised its purity, functionality and X-ray structural studies possibility. The dataset presented in this article provide a characterization of the Torpedo californi...
Article
Amphetamine-type stimulants (ATS) are the second most consumed illicit drug worldwide and lack good treatments for associated substance use disorders, lagging behind other addictive drugs. For this reason, a deeper understanding of the pharmacodynamics of ATS is required. The present study seeks to determine amphetamine (AMPH) enantiomers’ effects...
Article
Amongst primary brain tumors, gliomas are considered the most lethal malignant tumors due to their resistance to radiation and chemotherapy and the difficulty to accurately localize them within the tissue. Chlorotoxin (Ctx), a small neurotoxin of 36 amino acids isolated from the venom of the Israeli scorpion Leiurus quinquestriatus , binds specific...
Article
One of the limiting factors in the crystallization of membrane proteins is the process of solubilization mediated by detergents. During this process, preservation of the native protein structure and adjacent lipid environments is crucial for appropriate activity and stability. The detergent disruption of lipid–lipid and lipid‐protein interactions a...
