Storytelling Heals The Wounded Mind, Liliana Whitaker

Classical Conversations

Humans are storytelling creatures. We use stories to communicate ideas in a memorable and engaging way, inspire people to believe in the best version of themselves, find truth in our legal system, empathize with experiences different than our own, and entertain ourselves for hours on end. Recent neuroscience proposes that the human mind thinks through stories. Narrative is the technical and broad term for story, defined as a series of actions and events that unfold over time according to proper cause and effect. Narrative practice is an emerging field comprising of storytelling treatments in therapy and medicine, usually focusing on …

Faculty, Staff and Student Publications

Alzheimer’s Disease (AD) is a complex disease and the leading cause of dementia in older people. We aimed to uncover aspects of AD’s pathogenesis that may contribute to drug repurposing efforts by integrating DNA methylation and genetic data. Implementing the network-based tool, a dense module search of genome-wide association studies (dmGWAS), we integrated a large-scale GWAS dataset with DNA methylation data to identify gene network modules associated with AD. Our analysis yielded 286 significant gene network modules. Notably, the foremost module included the BIN1 gene, showing the largest GWAS signal, and the GNAS gene, the most significantly hypermethylated. We conducted …

Glial Lipid Droplets Resolve Ros During Sleep, Lindsey D Goodman, Matthew J Moulton, Hugo J Bellen

Duncan NRI Faculty and Staff Publications

The Sehgal lab presents data showing that the non-cell autonomous pathway of glial lipid droplet formation occurs during sleep and helps to resolve neuronal reactive oxygen species (ROS). This promotes neuronal function after an active day. Hence, this pathway has an important physiological function beyond its previously described role in ROS-associated diseases, including Alzheimer’s disease.

Blockade Of Rho-Associated Kinase Prevents Inhibition Of Axon Regeneration Of Peripheral Nerves Induced By Anti-Ganglioside Antibodies, Andrés Berardo, Cristian R Bacaglio, Bárbara B Báez, Rubén Sambuelli, Kazim A Sheikh, Pablo H H Lopez

Faculty, Staff and Student Publications

Anti-ganglioside antibodies are associated with delayed/poor clinical recovery in Guillain-Barrè syndrome, mostly related to halted axon regeneration. Cross-linking of cell surface gangliosides by anti-ganglioside antibodies triggers inhibition of nerve repair in in vitro and in vivo paradigms of axon regeneration. These effects involve the activation of the small GTPase RhoA/ROCK signaling pathways, which negatively modulate growth cone cytoskeleton, similarly to well stablished inhibitors of axon regeneration described so far. The aim of this work was to perform a proof of concept study to demonstrate the effectiveness of Y-27632, a selective pharmacological inhibitor of ROCK, in a mouse model of axon …

Activation Of Cerebral Ras-Related C3 Botulinum Toxin Substrate (Rac) 1 Promotes Post-Ischemic Stroke Functional Recovery In Aged Mice, Fan Bu, Jia-Wei Min, Md Abdur Razzaque, Ahmad El Hamamy, Anthony Patrizz, Li Qi, Akihiko Urayama, Jun Li

Faculty, Staff and Student Publications

Brain functional impairment after stroke is common; however, the molecular mechanisms of post-stroke recovery remain unclear. It is well-recognized that age is the most important independent predictor of poor outcomes after stroke as older patients show poorer functional outcomes following stroke. Mounting evidence suggests that axonal regeneration and angiogenesis, the major forms of brain plasticity responsible for post-stroke recovery, diminished with advanced age. Previous studies suggest that Ras-related C3 botulinum toxin substrate (Rac) 1 enhances stroke recovery as activation of Rac1 improved behavior recovery in a young mice stroke model. Here, we investigated the role of Rac1 signaling in long-term …
