Advanced confocal microscopy of inflammatory histopathologic components in strokeAdvanced confocal microscopy of inflammatory histopathologic components in stroke


Our NIH funded project investigates the interactions of neutrophils and cerebrovascular blood flow in mouse models of stroke. The lab uses transgenic fluorescent mice, optical coherence tomography and targeted immunologic manipulation in a mouse model of large vessel occlusion. We believe that understanding these relationships and spatiotemporal differences can lead to a better understanding in developing precision therapies for the innate immunity in stroke.

The Center for Healthy Aging at Stony Brook University has recently funded our lab for a translational clinical study investigating the innate immunity (neutrophils, monocytes and microglia) in both elderly and young stroke patients with large vessel occlusion and subsequent recanalization. We hope to obtain pilot data that demonstrates differences between immunologic responses as a function of age.

Lastly, in concert with Bioinformatics, we are also in the early stages of banking stroke tissue and physiologic data from our mice to understand variations in the model as it relates to animal behavior.
