Search Existing Tissue Requests

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.

Project Title: Identifying molecular mechanisms underlying resilience to the neuropathological hallmarks of Late-onset Alzheimer�s disease

Date: December 21, 2021 at 5:02 pm

Request ID: T1603

Aim 1: Determine cognitive resilience relevant biological pathways significantly enriched with genes (whole transcript, exon and exon junctions) that are differentially expressed between ADPC and LOAD patients

Aim 2: Explore an epigenetic basis for resilience factors by identifying differentially methylated genetic regions (DMRs) at CpGs between LOAD and ADPC brains

Project Title: Optimization and Validation of a Cell-based Assay for Blood-Based Diagnosis of Alzheimer�s Disease

Date: December 21, 2021 at 5:02 pm

Request ID: T1602

Aim 1: To test the performance of a recently developed indicator cell assay platform (iCAP) for blood-based diagnostics of AD. We propose to use 75 ADRC plasma samples to train and test iCAP-based classifiers to distinguish AD at pre-symptomatic and early stage of progression from normal controls.

Aim 2: To optimize the disease specificity of the AD iCAP. We propose to use 65 ADRC plasma samples to test and optimize the iCAP AD classifier�s ability to discriminate AD from other dementias such as lewy body dementia, frontotemporal dementia and vascular dementia.

Aim 3: To validate the final classifier with independent samples. We propose to use 125 ADRC plasma samples for blind independent testing of the classifiers. The final goal is a blood based iCAP for detection of presymptomatic and early AD with > 90% accuracy and specificity for AD over other dementias.

Aim 4: If only a fraction of the samples are available from ADRC, the project can be done using some samples from another source. In addition, as the aims are sequential, not all samples are required at once; we are willing to apply for approval in stages, contingent on meeting milestones for each aim.
