The ancient messenger molecule hydrogen sulfide (HS) modulates myriad signaling cascades and has been conserved across evolutionary boundaries. Although traditionally known as an environmental toxin, HS is also synthesized endogenously to exert modulatory and homeostatic effects in a broad array of physiologic functions. Notably, HS levels are tightly physiologically regulated, as both its excess and paucity can be toxic. Accumulating evidence has revealed pivotal roles for HS in neuroprotection and normal cognitive function, and HS homeostasis is dysregulated in neurodegenerative conditions. Here, we review the normal neuroprotective roles of HS that go awry in Alzheimer's disease, the most common form of neurodegenerative disease.
