There are 2 papers on membrane cholesterol in aging research: none in people yet, 2 in animals. The newest story, Oct 30, 2026: “Loss of a muscle protein mimics age-related changes in mice”.

Membrane cholesterol inhibits p38 MAPK signaling in mice (membrane cholesterol reduction in the aging brain).
“high p38MAPK activity in the hippocampus of old mice is in part due to the reduction in membrane cholesterol that constitutively occurs in the aging brain”

Experiments in male mice found that losing a muscle membrane protein reduced muscle strength and calcium entry and changed signaling by fat-derived molecules.Experiments in male mice found that losing a muscle membrane protein reduced muscle strength and calcium entry and changed signaling by fat-derived molecules.
