Research Focus:

How is it our brains—tangible entities—are able to store memories of intangible sights, sounds, emotions and ideas? What draws you toward one person, but repels you from another? My lab tries to answer these questions. Specifically, we explore how cyclic nucleotide signaling controls the formation of social memories and social interactions, and how alterations in this cascade might contribute to social deficits that are seen in patients with neurodevelopmental, psychiatric, and age-related disease. To do this, we identify molecular changes in tissue from patients and then mimic those changes in rodents in order to determine their behavioral, biochemical, and molecular consequences. We also use in vitro approaches to determine how mutations may change enzymatic activity or the subcellular compartmentalization of enzymes. Studies are conducted during development, early adulthood, and late adulthood in order to understand factors that modulate resiliency of the brain as well as those that trigger the manifestation of neurocognitive deficits later in life.

Our ultimate hope is that an improved understanding of the molecular mechanisms of social memory formation and social interactions will lead to the development of novel therapeutics for neurodevelopmental, psychiatric, and/or age-related diseases where these social behaviors are compromised.

FIGURE: Phosphodiesterase 11A4 (PDE11A4) is the only phosphodiesterase whose expression in brain is restricted to the hippocampal formation. This restricted expression pattern makes PDE11A4 a highly intriguing therapeutic target for neurodevelopmental, psychiatric and age-related disorders. Consistent with the fact that PDE11A4 is enriched in the ventral hippocampus, a brain region important in the regulation of mood and social behaviors, we have shown that decreasing PDE11A4 impairs the ability to form social memories, alters social interactions, and increases efficacy of the mood stabilizer lithium. DHIPP—dorsal hippocampus; VHIPP—ventral hippocampus.
