A “Mechanical Force” Immune Signal Emerges in the Alzheimer’s Choroid Plexus: Expansion of TTN-Positive Macrophages

These cells were increased in Alzheimer’s disease samples and showed features of aging, stress, and reduced cell communication, but “modulating tissue mechanics” remains only a therapeutic concept awaiting validation.
