Cigarette Smoke-Induced Cell Death Causes Persistent Olfactory Dysfunction in Aged Mice
Introduction: Exposure to cigarette smoke is a cause of olfactory dysfunction.We previously reported that in young mice, cigarette smoke damaged olfactory progenitors and decreased mature olfactory receptor neurons (ORNs), then, mature ORNs gradually recovered after smoking cessation.However, in aged populations, the target cells in ORNs by cigaret
