The team had also found that by restoring one particular ganglioside called GM1, they could reverse Huntington\u2019s symptoms in mice.<\/p>\n<p>One in every 7,000 Canadians has Huntington\u2019s, a genetic brain disorder with physical, mental and emotional symptoms, according to the <a href=\"https:\/\/braincanada.ca\/funding-opportunities\/2025-huntington-society-of-canada-brain-canada-navigator-research-program\/\" rel=\"nofollow noopener\" target=\"_blank\">Brain Canada Foundation<\/a>. It occurs when <a href=\"https:\/\/en.wikipedia.org\/wiki\/Huntington%27s_disease\" rel=\"nofollow noopener\" target=\"_blank\">mutant huntingtin protein<\/a> misfolds and clumps inside brain cells, causing them to malfunction and eventually die.\u00a0<\/p>\n<p>\u201cNow we know that when gangliosides are low \u2014 not just in Huntington\u2019s disease but also in Parkinson\u2019s and in other hereditary neurodegenerative diseases \u2014 the vesicle-mediated cell communication and clearance system doesn\u2019t work properly,\u201d says Sipione. \u201cThis allows harmful proteins such as mutant huntingtin to accumulate and thus contributes to the processes that drive neurodegeneration.\u201d\u00a0<\/p>\n<p>Sipione will continue research to fully understand the underlying mechanisms of gangliosides to determine their clinical potential.<\/p>\n<p>\u201cWe are still working to understand the full picture of how gangliosides protect the brain and how they might be used as restorative therapies in neurodegenerative diseases,\u201d says Sipione, who is collaborating with a biotech company to explore the possibility of future clinical trials. While gangliosides can be synthesized or extracted from the brains of other animals that have been used for meat consumption, and they have been used as therapeutic agents for other conditions, they are not approved for use in North America.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" alt=\"(From left) U of A researchers Elena Posse de Chaves, John Monyror and Simonetta Sipione are part of a team that discovered a link between low levels of brain molecules called gangliosides and symptoms of Huntington\u2019s disease, offering a new direction for potential treatment.

(Photo: Supplied)<\/p>\n<p>One hurdle is that when gangliosides are injected into the blood, very little makes it into the brain because of a protective feature known as the <a href=\"https:\/\/en.wikipedia.org\/wiki\/Blood%E2%80%93brain_barrier\" rel=\"nofollow noopener\" target=\"_blank\">blood-brain barrier<\/a>.
