Title	Targeting supramammillary circuits restores cognitive and noncognitive function in Alzheimer’s disease
Description	Although progressive cognitive decline is the hallmark symptom in Alzheimer’s disease (AD) patients, patients often develop noncognitive neuropsychiatric symptoms, such as anxiety and depression. The neural circuit basis for these different AD symptoms is poorly understood. Therapeutic strategies effectively targeting both cognitive and noncognitive symptoms in AD are largely lacking. Here we identified molecularly and functionally distinct supramammillary (SuM) subpopulations projecting to dorsal dentate gyrus (dDG) or ventral dentate gyrus (vDG), which differentially involved in memory and mood regulation. Interestingly, dDG- and vDG-projecting SuM neurons in AD model mice exhibited aberrant activity during cognitive and affective behaviors, respectively. Optogenetic activation of SuM-dDG or SuM-vDG pathways selectively rescued memory impairment and anxiety/depression-like behavioral deficits in AD mice. Furthermore, cross-species comparison of AD mouse and human phosphoproteomes revealed that SuM stimulation reversed pathological phosphorylation of mouse-to-human conserved proteins related to broad AD deficits. Thus, targeting SuM circuits may be an effective strategy for treating both cognitive and non-cognitive symptoms in AD patients.
