Dementia is a progressive multifactorial disorder and the only top cause of death that cannot be effectively treated or prevented. It will impact future generations with increasing magnitude and represents one of the biggest health challenges of our time.
We believe that basic and translational science can steer the course toward effective treatment and prevention of dementia and other devastating disorders of the brain. Dementia involves multiple converging pathobiological pathways. Impairments in glial functions and glial-neuronal interactions are emerging as central drivers of dementia and other CNS disorders. Our primary goal is to harness glial-neuronal interactions for treating and preventing disease, including frontotemporal dementia and Alzheimer's disease. We use multipronged experimental methods to unravel glial pathobiology, glial interactions with other neural cell types, glial roles in cognitive function and behavior, and how changes in glial cells influence disease.

Research Highlights
Normal Cognition Requires Sex-specific Input from Astrocytes
How are male and female brains different?
Our findings suggest that astrocytes modulate cognition in a sexually dimorphic manner and might promote certain differences in neural function between males and females. In female mice, we found that normal memory was enhanced by stimulating astrocytic Gi/o-coupled signaling, whereas reducing this signaling or stimulating Gs-coupled signaling impaired memory. However, in male mice, these pathways had the opposite effects. Thus, normal cognitive function may require a sex-specific balance in astrocyte signaling. Aging, disease, or therapeutic targeting of these pathways may alter this balance and promote sex-dependent changes in cognition and behavior.
Dementia-linked Protein Buildup in Astrocytes Disrupts Innate Antiviral Pathways, Promoting Selective Neuronal Vulnerability and Cognitive Decline
What causes cognitive decline in AD and FTD?
Our work reveals that aberrant extranuclear accumulation of TDP-43 in astrocytes occurs in dementia. In mouse models, this buildup was sufficient to disrupt antiviral immune mechanisms in specific brain regions and increase chemokine signaling by astrocytes. These changes promoted selective impairments in presynaptic transmission and cognitive function. Blockers of antiviral pathways and chemokine signaling might alleviate cognitive decline in dementia and related disorders.
Leveraging Existing Therapeutics to Counteract Cognitive Deficits
New results show that short-term treatment with low doses of a selective receptor blocker enhances spatial memory in aging animals with chronic amyloid pathology, suggesting that existing drugs might counteract cognitive dysfunction in people with neurodegenerative disease.
Precise Blockade of Cell Damage Caused by Reactive Oxygen
Mitochondria produce ATP, but also generate reactive oxygen species implicated in disease-related cell damage. Newly discovered tools will help to precisely target reactive oxygen species without affecting the crucial process of ATP production.
Astrocytes Promote Forgetting in Health and Disease
'Star-shaped' glial cells are known to support neuronal health and function. New findings suggest that these cells may also be crucial for information storage and contribute to memory loss in disease. Therapeutically targeting these cells might prevent cognitive dysfunction in diverse disorders.
