A bioengineered system could deliver neuroprotective molecules specifically to active synapses using activity-dependent promoters or calcium-sensitive delivery vehicles, creating a 'use it or lose it' protection system.
Debate provenance: derived from debate `sess_sda-2026-04-01-gap-v2-691b42f1` on question: Synaptic pruning by microglia in early AD. Consensus signal: domain_expert, skeptic, synthesizer, theorist discussed the mechanism terms ARC, Activity-Dependent, Protection, Synaptic, System, synaptic. Novelty signal: skeptic-discussed-with-qualified-concession.
