Variants in a newly discovered microprotein affected the risk of Alzheimer’s disease more than any other known risk variant besides ApoE. The protein, dubbed SHMOOSE by its discoverers, was identified in a mitochondrial-wide association study (miWAS). The researchers reported their findings in the Sept. 21, 2022, issue of Molecular Psychiatry. The newly identified variant is not rare – it occurs in about a quarter of the Caucasian population, slightly more than the ApoE4 allele. Its effects are also not subtle – in their paper, the team estimated that those with the high-risk variant SHMOOSED47N were roughly 30% more likely to develop AD than those without.
Pretzel Therapeutics Inc. has launched with a $72.5 million series A financing to pioneer novel therapies to modulate mitochondrial function to treat rare genetic diseases and common diseases of aging.
Investigators at Northwestern University’s Feinberg School of Medicine have used a new mouse model of Parkinson’s disease to confirm a causal role for mitochondrial dysfunction in Parkinson’s disease. More surprisingly, the same model has called into question previously uncontroversial notions about the motor features that are PD’s most conspicuous feature.
In Cell Metabolism, researchers working at the University of Texas Southwestern Medical Center reported that when fat cells (adipocytes) are chronically stressed, as is characteristic of obesity, they can release small vesicle exosomes that are respiration-competent and essentially portions of mitochondria.
Minovia Therapeutics Ltd. will collaborate with Astellas Pharma Inc. to research, develop and commercialize cell therapy programs for treating diseases brought on by mitochondrial dysfunction. The candidates will come from Astellas’ genetically engineered, induced pluripotent stem cells. Haifa, Israel-based Minovia will receive $20 million in cash up front.
Researchers at INSERM have gained new insights into the basic biology of mesenchymal stem cell function, and how platelets improved that function in an animal model of wound healing.
