What Standard Proteomics Misses in the Alzheimer’s Brain

What if the human brain contains thousands of proteins missing from the reference catalogs we rely on?
In this episode, we examine a 2026 Nature Aging study by Brendan Miller, Alan Saghatelian, and colleagues that mapped 1,067 previously uncatalogued microproteins in the human dorsolateral prefrontal cortex.
The researchers identified 4,321 microproteins with mass-spectrometry evidence and found 22 unreviewed microproteins associated with Alzheimer’s disease. One, micro-MKKS63, a 63-amino-acid protein, was reduced in symptomatic Alzheimer’s tissue and showed effects on mitochondrial respiration in human microglial cells.
The key question is what these findings actually mean. The study does not establish causation or show that these proteins are therapeutic targets. Instead, it reveals a previously overlooked layer of human biology and suggests that current protein catalogs may be substantially incomplete.
