Molecular mechanisms of HD are not sufficiently understood, and no cure is currently available. Here, we demonstrate neuroprotective effects of hepatoma-derived growth factor (HDGF) in cellular and mouse HD models. We show that HD-vulnerable neurons in the striatum and cortex express lower levels of HDGF than resistant ones. Moreover, lack of endogenous HDGF exacerbated motor impairments and reduced the life span of R6\/2 Huntington\u2019s disease mice. AAV-mediated delivery of HDGF into the brain reduced mutant Huntingtin inclusion load, but had no significant effect on motor behavior or life span. Interestingly, both nuclear and cytoplasmic versions of HDGF were efficient in rescuing mutant Huntingtin toxicity in cellular HD models. Moreover, extracellular application of recombinant HDGF improved viability of mutant Huntingtin-expressing primary neurons and reduced mutant Huntingtin aggregation in neural progenitor cells differentiated from human patient-derived induced pluripotent stem cells. Our findings provide new insights into the pathomechanisms of HD and demonstrate neuroprotective potential of HDGF in neurodegeneration.<\/jats:p>","DOI":"10.26508\/lsa.202302018","type":"journal-article","created":{"date-parts":[[2023,8,14]],"date-time":"2023-08-14T10:30:14Z","timestamp":1692009014000},"page":"e202302018","update-policy":"https:\/\/doi.org\/10.26508\/lsa.crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["Neuroprotective
