Summary of Research Contributions
Dennis O'Leary studies the development and plasticity of the vertebrate nervous system. His work focuses on two broad issues: development of neural connectivity and development of the cerebral cortex. To address these issues, O'Leary and his research group use genetic manipulations in mice and chick embryos, in vivo analyses and in vitro assays, and a range of techniques including molecular and cell biology, biochemistry, imaging, and behavioral testing.
O'Leary's goal is to understand fundamental developmental events in the nervous system, to establish a framework to design effective strategies to overcome birth defects, neurological diseases and disorders, and injury.
Development of Neural Connectivity
O'Leary discovered fundamental mechanisms involved in the development of neural connectivity that challenged and supplanted dogma at the time. These discoveries include (i) exuberant axonal projections, (ii) selective axon elimination and the underlying mechanisms, and (iii) interstitial axonal branching as the predominant mechanism of target recognition.
O'Leary's work demonstrated that specific axonal connections arise from initially exuberant projections followed by pruning through a mechanism of selective large-scale axon degeneration. He has established that this naturally-occurring axon pruning is a fundamental characteristic of vertebrate neural development and occurs through a caspase-dependent mechanism that is morphologically similar but molecularly distinct from “Wallerian” degeneration. O'Leary also has shown that the de novo interstitial branching of primary axons is the predominant mechanism of target recognition and innervation in vertebrates, and has determined cellular and molecular mechanisms of its control.
O'Leary's studies on the development of topographic maps in the visual system have defined the predominant mechanisms of topographic axon mapping and novel functions of ephrin-Eph signaling in axon guidance and mapping. This work has established novel cellular and molecular mechanisms for map development, including topographic axon branching as a crucial event in map development that requires unique functions for axon guidance molecules that are distinct from their control of growth cone targeting, and the relative roles of patterned activity and molecular guidance molecules. O'Leary has made prominent contributions to defining functions for ephrins and Ephs in axon guidance and mapping, has shown that distinct ephrins and Ephs regulate interstitial axon branching and direct branch extension, act bifunctionally as repellents and attractants and bidirectionally through forward- and reverse-signaling. His work is the first to determine receptor mechanisms of ephrin-A reverse signaling and the modulation of EphA forward signaling by complexing with neurotrophin receptors.
Development of the Cerebral Cortex
O'Leary has made pioneering contributions to cortical development, especially patterning of the neocortex into functionally-specialized areas. He has pioneered the role of intrinsic genetic mechanisms that specify area identities of cortical progenitors and their neuronal progeny, including the first identification of transcription factors that specify the area identity of progenitors and unique functions for morphogens in progenitor differentiation and regulation of cortical size. Based on this work, O'Leary has proposed a model of neuronal specification for higher brain centers distinct from the model developed from studies of the spinal cord. His group has also established genetic mechanisms for the determination of regional-fate in the cerebral cortex, for example the genetic regulation of the fate decision in telencephalic progenitors to generate olfactory cortex versus neocortex.
Complementing the genetic regulation of forebrain patterning, O'Leary has demonstrated mechanisms of plasticity in area patterning of the neocortex, including novel roles for afferent based mechanisms. Recently, he and his group have found a form of “top-down” plasticity not previously recognized in which the intrinsic genetic specification of cortical sensory areas determines the representation of the sensory periphery within them and drives the subsequent re-patterning of thalamic sensory nuclei to match their cortical counterparts.
