The microtubule (MT) network and associated regulatory proteins play a critical role during viral infection from facilitating viral particle transport towards the nucleus upon entry to later mediating virion assembly and egress. Many of the precise mechanisms by which viruses commandeer the host MT network to propagate infection remain poorly...
Biological therapeutics have revolutionized the way we treat cancer due to their ability to target tumors discriminately, leaving healthy cells unaffected. However, our inability to tailor the structure of biologics may hamper their optimization for efficacy. This lack of programmability contributes to factors such as immunogenic responses, inability to penetrate...
Proprioception, or the sense of one’s body in space, provides critical feedback that the brain usesto generate controlled movements. When proprioceptive feedback is lost, people find it difficult
to perform even basic motor tasks. Despite its importance, proprioceptive coding of single
neurons in the cuneate nucleus (CN), the most peripheral...
In memory overgeneralization, details from negatively-valenced episodic memories become excessively generalized to unrelated neutral situations. This is a key cognitive distortion associated with major depressive disorder (MDD), generalized anxiety disorder (GAD), and post-traumatic stress disorder (PTSD). Stress promotes memory generalization, and this process likely relies on stress-induced changes in dorsal...
Anthropogenic consumption of fossil fuels releases carbon into the Earth-atmosphere-ocean system at rates unmatched by geologic processes. Yet, some geologic time periods also show evidence of climate forcing related to rapid natural greenhouse gas emissions and can serve as tools to help understand the future trajectory of climate.
