The aged mouse was injected intraperitoneal (ip) with Escherichia coli lipopolysaccharide (LPS, 0.33mg/kg body weight (BW), ~10ug/mouse; serotype O127:B8, Sigma) and was killed 4 hours after injection by CO2 asphyxiation. Brain was removed, separated in half at the longitudinal fissure, frozen in liquid nitrogen and stored at -80C until use.
