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: Study of vascular dysfunction in brain of two transgenic rodent models of Alzheimer�s disease (AD): dietary impact and relevance to human AD

Date: December 21, 2021 at 5:02 pm

Request ID: T1616

Aim 1: Determine the contribution of neurovascular units (endothelial cells, astrocytes, pericytes, microglia, and basement membranes) and associated cerebrovascular integrity in the deposition of microvascular and/or parenchymal amyloid beta (A�) and/or abnormal tau protein in two rodent models of AD
