Temporal Complement Activation Windows
🧪 Overview
Cognitive and anxiety phenotypes emerge from different temporal phases of complement activation - early C3a/C5a inflammatory signaling causes anxiety through direct neuronal excitation, while delayed C1q-mediated synaptic elimination causes cognitive deficits. Time-specific complement inhibition could selectively prevent each phenotype.
Debate provenance: derived from debate `sess_SDA-2026-04-08-gap-pubmed-20260406-062128-34a47c4e` on question: The study reports that complement-mediated synaptic elimination produces both cognitive deficits and anxiety-like behaviors, but doesn't explain how the same hippocampal synaptic loss generates these distinct behavioral phenotypes. This mechanistic gap limits understanding of perioperative neurocogn. Consensus signal: domain_expert, skeptic, synthesizer, theorist discussed the mechanism terms Activation, C1QA, C3AR1, C5AR1, Complement, Temporal, Windows, activation. Novelty signal: skeptic-discussed-with-qualified-concession.
