A group of German and French scientists has identified 15 genetic variants in a proteasome protein complex that are related to neurodevelopmental delay and also alter interferon type 1-mediated immune signaling. The finding contributes to the diagnosis of this neurological disorder and gives an opportunity for the development of therapies in patients who have these mutations.
Researchers have discovered that a subunit of the ubiquitin-proteasome system acted independently of the proteasome machinery to regulate AMPA receptors, a type of glutamate receptor, at multiple steps of their life cycle. Published in the May 26, 2023, issue of Science, the findings could point to ways to target AMPA receptors. They are responsible for the majority of excitatory transmission in the central nervous system, and current drugs seeking to influence AMPA-based transmission are “good but they are not great,” Erin Schuman told BioWorld. “This regulatory particle is watching the glutamate receptor at each step.” Schuman is the director of the Max Planck Institute for Brain Research and the paper’s senior author.
In its second acquisition of the past four weeks, Lodo Therapeutics Corp., acquired Hibiskus Biopharma Inc. plus exclusive worldwide rights from the University of California Riverside and Michigan State University to preclinical proteasome and immunoproteasome inhibitors developed by Hibiskus’ two co-founders.
