A key issue within the field of neuroscience is understanding how genetic programs in fixed neural circuits are able to guide state-dependent innate behaviors. Innate behavior is governed by the integration of both environmental stimuli and internal state. Biological sex represents a naturally occurring variation in internal state that has been shown to play a role in influencing animal behavior. For example, the simple nematode C. elegans are able to switch between locomotion behavior states based upon both external stimuli an internal state. However, much of this locomotive behavior has solely been studied in the hermaphrodite and not the male C. elegans. Males, unlike self-fertilizing hermaphodites, must integrate two major needs, feeding and finding a mate, to determine the optimal locomotive state. Understanding how mating cues from pheromones, different food stimuli, and biological sex influence C. elegans locomotor states will give key insights into how, on a fundamental level, neural circuits integrate sensory cues with internal state to generate adaptive behavioral flexibility. In this proposal, I will investigate how both pheromone mating cues and food signals influence the locomotive states of both male and hermaphrodite C. elegans.

Acute ischemic stroke is a leading cause of death and disability in the aging population. Although available interventions improve recanalization rates, there remain no therapies to treat delayed ischemia-reperfusion injury (IRI). The discrete signals responsible for IRI involve a complex cascade of innate immune priming, neuroinflammation, and delayed post-ischemic neurodegeneration. Emerging evidence implicates organ crosstalk in the pathology of delayed central nervous system (CNS) damage following global cerebral ischemia. In this project, we tested the hypothesis that the prevailing inflammatory milieu within the lung is an essential determinant of post-stroke CNS injury. To test this, we investigated the relationship between acute brain ischemia, lung inflammation, and CNS reperfusion injury in the middle cerebral artery occlusion (MCAO) model of stroke. In male C57Bl6J mice, ischemia-reperfusion was associated with pulmonary function changes, vascular inflammation, and airway immune infiltration. In post-stroke lung tissue, the loss of endogenous SOD3 correlated with increases in 4-HNE modified proteins indicative of elevated oxidant stress. Conversely, mice that express human SOD3 within type II pneumocytes (TgSOD3) exhibited lower post-stroke levels of 4-HNE protein modification and vessel inflammation versus wildtype controls. TgSOD3 mice exhibited reduced blood-brain barrier (BBB) damage and developed smaller infarct volumes 72 hours post-stroke. We also observed sex-related differences in the SOD3-dependent regulation of post-ischemic IRI. Higher basal expression of lung SOD3 observed in female mice was associated with smaller infarcts, a reduced burden of post-stroke hemorrhage, and lower myeloperoxidase levels, ICAM-1, and fibrinogen. These results collectively implicate lung-derived SOD3 as a modulator of neurovascular injury in acute ischemic stroke. Future work defining SOD3 regulation in the lung, lung-dependent immune priming, and the remote effects of SOD3 on the cerebrovasculature could open up a new field of lung-targeted therapies for stroke and other acute neuroglial disorders.

We use our nervous system throughout life to sense the world around us and respond with meaningful behaviors. Enabling this are its two major cell types, neurons and glia, which exist in about equal numbers in the human brain. Constant glia-neuron molecular interactions are critical for nervous system development, function and aging and their impairment correlates with many neurological diseases. However, roles of glia in neural functions remain poorly understood in molecular mechanistic detail. We previously helped establish C. elegans as a powerful experimental platform to molecularly dissect glia-neuron interactions in vivo. This has led us to uncover novel molecular pathways and logic by which glia regulate neuron shape and animal behaviors. This includes our recent discovery that C. elegans glia prune neuron-endings through life, like mammalian glia. Our uncovering the underlying machinery at single glia-neuron resolution led us to find that glia actively direct pruning to control neuron shape and function, and identify the glial molecular rheostat tuning this process. Broad conservation and disease-relevance of all C. elegans glial cues and functions we are uncovering underscores the potential of this genetically tractable model to define glial roles in neural health and disease with exquisite speed and molecular precision.
