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: Plasma protein-mediated effects of ApoE4 expression on brain in AD

Date: [208]

Request ID: T1902

Project Title: Assessment of neuritic plaque p-tau, A�42, and microgliosis in AD-associated TREM2 variant carriers

Date: [208]

Request ID: T1419-A

Investigator: Randall Bateman M.D.

Project Title: A blood isotope labeled amyloid-beta test for Alzheimer’s disease

Date: [208]

Request ID: T1822

Aim 1: To determine blood Aβ isoform level relationships to CSF Aβ and amyloid PET, using archived blood samples from cross-sectional and longitudinal studies of cognitively normal, AD, and other neurodegenerative dementias.

Aim 2: We would like to explore if there are changes (perhaps diffuse plaques or biochemical changes) in the neuropathology cases that also have collected blood samples near the time of brain donation (within 1 or 2 years is best)

Aim 3: The hypothesis is that the plasma abeta42/40 will be abnormal at times when amyloid plaque (including diffuse) begins and before PET scans would detect it.

Aim 4:


Investigator: Wim Annaert
