Art v 1 and Amb a 4 Co‐Sensitization Identifies Italian Patients at Risk for Mugwort‐Celery‐Spice Syndrome

Allergy, EarlyView.
Three molecular profiles identified among Art v 1/Amb a 4‐sensitized patients: Art v 1 monosensitization, Amb a 4 monosensitization, and dual sensitization to both allergens. Art v 1 monosensitization was predominantly associated with allergic rhinitis, reflecting a classical airborne allergy pattern.

Characterization of Four Medically Important Toxins from Centruroides huichol Scorpion Venom and Its Neutralization by a Single Recombinant Antibody Fragment

Toxins, 2022
Centruroides huichol scorpion venom is lethal to mammals. Analysis of the venom allowed the characterization of four lethal toxins named Chui2, Chui3, Chui4, and Chui5.

[Scorpion toxins and defensins].

Comptes rendus des seances de la Societe de biologie et de ses filiales, 1998
Les venins de scorpion contiennent un grand nombre de neurotoxines peptidiques qui constituent un ensemble de familles molécu­laires à haut degré de polymorphisme, mais qui ont en commun une architecture semblable. Cette architecture se retrouve dans des peptides antibactériens circulants de la famille des défensines, qui s'apparentent tout ...

Insects and Survival: A Review of Primary and Secondary Defense Strategies

Entomologia Experimentalis et Applicata, EarlyView.
Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.

Integration of phylogenomics and molecular modeling reveals lineage-specific diversification of toxins in scorpions [PDF]

PeerJ, 2018
Scorpions have evolved a variety of toxins with a plethora of biological targets, but characterizing their evolution has been limited by the lack of a comprehensive phylogenetic hypothesis of scorpion relationships grounded in modern, genome-scale ...

Conkazal‐M1 from the MKAVA family of conotoxins: A dual‐function protease inhibitor and neuroactive peptide

Protein Science, Volume 35, Issue 5, May 2026.
Abstract Marine cone snails produce a diverse array of bioactive peptides, known as conotoxins, in their venom. Given their high target potency and specificity, conotoxins are attractive compounds for the development of precision research tools and pharmacological agents.
