A frontal-cortex microprotein atlas found 1,067 uncharacterized proteins in Alzheimer’s brains

What the research found
Study (human tissue atlas). Brendan Miller, Alan Saghatelian and Salk colleagues report in Nature Aging (doi 10.1038/s43587-026-01207-x) on 480 ROSMAP frontal-cortex samples with and without Alzheimer’s disease. Using ShortStop plus mass spectrometry they identified 1,067 previously uncharacterized microproteins; hundreds differed in Alzheimer’s tissue. In microglia, knocking out one microprotein-coding gene impaired mitochondria, suggesting a possible immune-cell energy link. Atlas work, not a treatment. Educational research notes, not a diagnosis or a supplement claim.
