Abstract Nitric oxide (NO)-dependent activation of soluble guanylyl cyclase (sGC) is essential for maintaining cerebrovascular function and cognitive processes. However, sGC is susceptible to oxidative inactivation under vascular and neurodegenerative stress. This study investigated the impact of chronic sGC oxidation on ophthalmic artery (OphA) hemodynamics, brain cGMP signaling, and memory performance in vivo. Young adult C57BL/6 mice were treated for one month with the heme-oxidizing agent ODQ.

Abstract Growing epidemiological and mechanistic evidence indicates that infections substantially increase the risk of Alzheimer’s disease (AD) and related dementias. Systemic immune activation and pathogen persistence may act as upstream triggers accelerating neurodegenerative cascades.
