Molecular Diversity and Isoform Evolution in Tityus obscurus Venom: Insights from Proteomic Analysis

open access: yesToxins
Over millions of years of evolution, natural selection has driven the specialization of predatory and defensive mechanisms in various animal species through the development of poisons and venoms.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Neurotoxic Alkaloids: Saxitoxin and Its Analogs

open access: yesMarine Drugs, 2010
Saxitoxin (STX) and its 57 analogs are a broad group of natural neurotoxic alkaloids, commonly known as the paralytic shellfish toxins (PSTs). PSTs are the causative agents of paralytic shellfish poisoning (PSP) and are mostly associated with marine ...

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Druggability of Voltage-Gated Sodium Channels—Exploring Old and New Drug Receptor Sites

open access: yesFrontiers in Pharmacology, 2022
Voltage-gated ion channels are important drug targets because they play crucial physiological roles in both excitable and non-excitable cells. About 15% of clinical drugs used for treating human diseases target ion channels.

Grayanotoxin I Intoxication in Pet Pigs [PDF]

open access: yes, 2018
Contaminated honey is a common cause of grayanotoxin intoxication in humans. Intoxication of animals, especially cattle, is usually due to ingestion of plants of the Ericaceae family, such as Rhododendron. Here, we report the ingestion of Pieris japonica
