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: Combining plasma phospho-tau217 and Aβ42/40 to detect early development of amyloid pathology in early Alzheimer’s disease
Date: [153]
Request ID: D2336
Aim 1: To establish if a combination of p-tau217 and Aβ42/40 performs better than p-tau217 by itself or Aβ42/40 by itself when (1) identifying CU individuals and patients with MCI who have abnormal brain Aβ burden and (2) predicting change in brain Aβ burden over time.

Investigator: John Morris
Project Title: Sex differences in Alzheimers Disease
Date: [153]
Request ID: D2337
Aim 1: Are women at an increased risk of developing AD?
Aim 2: Determine sex-specific differences in the clinical manifestations of AD symptomatology as a function of pathology.
Aim 3: Determine if the relationship between AD biology, particularly tau as measured by PET, and cognition varies by sex.
Aim 4: Do men and women show differences in amyloid, tau, and cognition as a function of sex and APOE status? Are there additional factors that might vary by sex?
Investigator: Alison Goate
