The Knight ADRC has supported many investigators at Washington University and at other institutions over the years. We wish to avoid the situation where two investigators study the same research question to avoid duplication of effort and potential conflict. To determine if your topic has already been studied with our resources, please search our database. If you find that your topic or a related topic has been submitted, you may wish to contact the investigator to inquire about their findings to determine how you might proceed. You may wish to collaborate or modify your request to avoid overlap. The results below reflect requests made since online requests have been accepted. As such, not all fields will have data as certain information, such as aims, were not collected until recently. If an entry has been assigned an ID number (e.g. T1004), the full request has been submitted and is either approved, disapproved or in process. If an entry has no ID number, then it represents a submission that has not yet been reviewed. Search terms are applied across an entire requests application including variables not displayed below. A more specific, detailed search may yield better results depending upon your needs.

Investigator: Hongyu AN
Project Title: Neuroinflammation in Cerebral Small Vessel Disease using PET/MR Imaging
Date: October 15, 2024 at 9:51 am
Request ID: T2302-A
Aim 1: Determine if S1PR1 expression increases and colocalizes with microglia and astrocytes in post-mortem brain specimens from deceased patients with underlying CSVD.
Aim 2: Determine if neuroinflammation measured by 11C-CS1P1 uptake is independently associated with CSVD structural endpoints using in vivo PET/MR imaging.

Investigator: Heleen Verlinden
Project Title: Comprehensive analysis of cellular responses to Alzheimer’s and comorbid pathologies
Date: September 13, 2024 at 4:54 am
Request ID: T2416
Aim 1: To identify the cellular transcriptional changes to AD pathology in the superior frontal gyrus of postmortem human brains.
Aim 2: We aim to identify the cellular transcriptional changes to amyloid plaques without tau pathology compared to amyloid-associated tau pathology. This will help to refine the mechanism resolving amyloid stress or preventing amyloid-induced tau pathology.
Aim 3: Our overall aim is to identify new medicines to preserve cognition and other brain functions, enhance resilience to disease pathology, and slow or stop the progression of neurodegenerative diseases.
Aim 4:

Investigator: Meredith Jackrel and Jennifer Heemstra

Investigator: Henry Houlden
Project Title: Investigating the transcriptomic and genomic profiles of rare neurodegenerative disorders
Date: August 22, 2024 at 6:08 am
Request ID: T2414
Aim 1: Generate paired long-read DNA and RNA-seq data in each case
Aim 2: RNA expression of disease gene (and repeat expansion sizes) will differ in brain regions
Aim 3: Use this genomic and transcriptomic map to re-assess the pathogenicity of variants
Aim 4: Clinical correlation of expression differences and repeat expansion sizes in brain tissue
