• Welcome to LaNeurotox

    Headed by the Principal Investigator Celia Carlini, the LaNeurotox – Laboratory of Neurotoxins, is part of the Brain Institute (Instituto do Cérebro – InsCer), Pontifícia Universidade Católica do Rio Grande do Sul (UFRGS), in the city of Porto Alegre, RS, Brazil. At LaNeurotox, we study, at the physicochemical and biological levels, proteins and peptides with neurotoxic properties. We work in close collaboration with the Laboratory of Toxic Proteins – Laprotox (www.ufrgs.br/laprotox), Center of Biotechnology, Universidade Federal do Rio Grande do Sul (UFRGS), also coordinated by Dr. Carlini.

    Ureases are multifunctional toxic proteins. At LaNeurotox we apply cellular, molecular and biophysical approaches to study the structural and biological properties of ureases from bacteria, fungi and plants. We aim to understand how ureases exert their many biological roles (enzyme, defense, virulence factor, communication) in the source organisms and in those affected by their actions. We are particularly interested in understanding how the neurotoxic properties of ureases and derived peptides contribute to their insecticidal activity and excitotoxicity to mammals.
