Pathways underlying selective neuronal vulnerability in Alzheimer's disease: contrasting the vulnerable locus coeruleus to the resilient substantia nigra

Project description:Identifying factors underlying selective neuronal vulnerability is crucial for understanding Alzheimer's disease (AD) pathophysiology. The Neuromodulatory Subcortical System (NSS) includes nuclei that exhibit early, but varied vulnerability to tau accumulation and neuronal loss. This varied vulnerability represents a valuable opportunity to explore the underlying mechanisms of AD. In this study, we investigated factors contributing to selective neuronal vulnerability by comparing transcriptomic profiles of two similar NSS nuclei with differing vulnerabilities to AD, the locus coeruleus and substantia nigra. Using paired samples from well-characterized postmortem human tissue from individuals in early Braak stages and free of comorbid neuropathologic diagnoses, we identified pathways related to cholesterol homeostasis and antioxidant pathways response as key potential drivers of vulnerability.

Transcriptional interaction network analyses in dorsal nucleus of vagus nerve, locus coeruleus and substantia nigra in Parkinson's disease

Project description:We analyzed the transcriptomic profile of post-mortem explants from dorsal nucleus of vagus nerve, locus coeruleus and substantia nigra obtained from controls and Braak 4 (BK4) and 5 (BK5) stages of Parkinson’s disease (PD) patients in order to investigate how gene-gene interaction patterns vary along different anatomical regions in patients and controls. The comparative transcriptional networks analyses indicate that the main hubs in PD networks are related to ubquitin/proteasome, oxidative stress, neuroprotection, neurogenesis and PD associated proteins.

Age-mediated transcriptomic changes in adult mouse substantia nigra

Project description:Substantia nigra pars compacta (SNpc) is highly sensitive to normal aging and selectively degenerates in Parkinson's disease. Until now, molecular mechanisms behind SNpc aging have not been fully investigated using high throughput techniques. Here, aging-associated early changes in transcriptome of SNpc were investigated comparing late middle-aged (18 months old) to young (2 months old) mice.

Transcriptomic profiling of substantia nigra and putamen in Parkinson’s disease

Project description:We report RNA sequencing results of human substantia nigra and putamen samples from Parkinson's disease patients and controls. Each substantia nigra sample is the result of pooling brain tissue from two individuals with the same , while each putamen sample is the result of pooling brain tissue from three individuals. We found 354 differentially expressed genes (DEGs) in the SN of PD patients compared to age-matched controls, while we observed 261 DEGs in the putamen samples. The top-enriched pathways from the SN were associated with “protein folding” and “neurotransmitter transport”, and the putamen DEGs with “synapse organization”. In summary, our data confirms the key role of protein folding and neuronal degeneration in the pathology of PD, and highlights new genes and pathways that have not yet been explored in the context of PD.
