📣 Anle138b ameliorates pathological phenotypes in mouse and cellular models of #HuntingtonsDisease By M. da Silva Padilha, @irinadudanova.bsky.social & colleagues @unicologne.bsky.social 🗞️ doi.org/10.1038/s44321-026-00459-9

Anle138b ameliorates pathological phenotypes in mouse and cellular models of Huntington’s disease - EMBO Molecular Medicine

Huntington’s disease (HD) is a hereditary movement disorder caused by a CAG repeat expansion in the huntingtin gene. HD is characterized by deposition of mutant huntingtin (mHTT) aggregates, and by severe neurodegeneration of the basal ganglia and neocortex. No cure is currently available, and new treatment options are urgently needed. Here, we show that the oligomer modifying molecule anle138b (INN: emrusolmin) improves multiple disease phenotypes in cell culture and in two mouse models of HD. Application of anle138b reduced mHTT aggregate formation and ameliorated neurotoxicity in primary neurons. Oral administration of anle138b delayed deposition of mHTT inclusions, reduced brain atrophy, mitigated neuroinflammation and transcriptional alterations, improved motor function and extended life span in HD mice. Downregulation of striatal markers and synapse loss in striatal spiny projection neurons were also partially rescued. No adverse effects of anle138b were observed in wildtype animals. Moreover, anle138b markedly decreased mHTT aggregation in human neural precursor cells differentiated from HD patient-derived induced pluripotent stem cells (iPSCs). Altogether these results illustrate the potential of anle138b as a disease-modifying treatment for HD.

Our joint study with Takaki Komiyama @takakikomiyama.bsky.social is out in @nature.com! We found cell type-specific changes in the cortical circuit of Huntington’s disease mice. Optogenetic stimulation of VIP interneurons rescued circuit dysfunction and improved motor behavior.

In a mouse model of Huntington’s disease, targeted modulation of neuronal activity restores network function and improves motor deficits.

I am starting a new chapter as Full Professor and Chair of Anatomy and Cell Biology at the University of Würzburg. I am deeply grateful to all my wonderful colleagues in Cologne with whom I've had the pleasure of working together. I will miss the great environment of the Uniklinik campus.

Happy to share our new preprint, where we find that anle138b reduces Huntingtin inclusions and improves disease phenotypes in #Huntington’sDisease models, showing its potential as an HD treatment. Great work by Miguel Padilha and several wonderful collaborators including thevilchezlab.bsky.social
