  The underlying mechanism of scorpion venom peptide BmK AS in reducing epilepsy seizures: mediated through dual modulation of Nav1.6 and the inflammasome pathway Abstract Introduction:  Voltage-gated sodium channel (VGSC) dysregulation, particularly of the Nav1.6 subtype, is a core mechanism underlying epileptogenesis and its associated neuropsychiatric comorbidities. The scorpion venom peptide BmK AS has demonstrated anticonvulsant potential, but its efficacy in chronic epilepsy and the precise mechanisms of action remain undefined. Methods:  Here, we show that BmK AS exerts robust anti-epileptic and neuroprotective effects through converging mechanisms. In a kainic acid-induced mouse model, BmK AS treatment reduced mortality and seizure parameters. Electrophysiological studies assessed BmK AS modulation of VGSC subtypes. The functional relevance of Nav1.6 targeting was confirmed by the loss of BmK AS’s anti-seizure efficacy upon its pharmacological blockade in a PTZ-in...

First record of Abapeba grassima (Chickering, 1973) (Araneae, Corinnidae, Corinninae) from Colombia

Abstract

The family Corinnidae includes spiders with wide distribution and diverse morpho-logy. This study records for the first time, the occurrence of the species Abapeba grassima (Chickering, 1973) in Colombia. Additionally, descriptions and images of the specimens, including male and female genitalia are provided. We also present a current distribution map of the species, including the new records from northern Colombia.
