PINK1 and Parkin Link Parkinson’s Disease to Failed Mitochondrial Cleanup

MHD featured image for PINK1, parkin, mitophagy, and mitochondrial cleanup in Parkinson's disease.

A 2026 review ties the Parkinson’s disease genes PINK1 and parkin to damaged-mitochondria cleanup, from damage sensing and ubiquitin tagging to autophagy recruitment and lysosomal degradation.1 That shifts “mitochondrial dysfunction” into specific failure points: tagging, extraction, transport, autophagosome recruitment, and degradation. Research Highlights 18 PARK loci frame inherited risk: PARK2 encodes parkin and PARK6 encodes …

Parkinson’s Sex Differences: Male Flies Show Stronger Rotenone Stress

MHD featured image for Parkinson's sex differences and rotenone immune-gene response in Drosophila.

A 2026 Drosophila Parkinson’s model exposed male and female flies to 500 μM rotenone. By 60 days, male flies had worse survival/climbing than female flies; the paper is a vulnerability screen, not evidence that the same genes are ready human biomarkers.1 Research Highlights 500 μM rotenone split male and female flies: Iyer et al. used …
