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: Neuropathological studies of primary age-related tauopathy: the PART working group

Date: December 21, 2021 at 5:02 pm

Request ID: T1512

Aim 1: Aim 1. To validate the neuropathological criteria for PART and lay the groundwork for clinical and mechanistic studies that will elucidate disease burden, pathogenesis and progression.

Aim 2: Aim 2. To test the hypothesis that PART has a molecular signature consisting of AD-type tau pathology alongside non-amyloidogenic APP metabolites.

Aim 3: Aim 3. To test the hypothesis that PART has a genetic risk profile that overlaps with some aspects of AD genetics (e.g., MAPT haplotypes) but diverges with respect to others (e.g., APOE genotype).
