Search DIAN Tissue Requests

In order to avoid the situation where two investigators study the same research question, please search our database to determine if your topic has already been studied. If you find that your topic or a related topic has already been submitted, you may wish to contact the investigator to inquire about his/her 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 # (e.g. DIAN-T1004), the full request has been submitted and is either approved, disapproved or in process.

Title:

Plasma Levels of an N-terminal Tau Fragment as Predictors of Cognitive Decline and Neurodegeneration in DIAN

Date of Request:

12/10/2019

Status:

approved

ID:

DIAN-T1915

Aim 1:

Using cross-sectional and longitudinal plasma samples from DIAN, we will assess levels of plasma NT1 (SIMOA) and correlate these with estimated years to symptom onset (EYO), rates of neurodegeneration (MRI-based), and cognitive performance (using the DIAN global cognitive composite).

Aim 2:

Using pre-existing measures of NfL from prior DIAN studies, we will compare and contrast the associations of plasma NfL and NT1 to cognitive and neurodegenerative trajectories.

Aim 1:

To determine whether therapeutic candidates can affect Abeta processing in cultured fibroblasts from autosomal dominant Alzheimer disease (ADAD) patients with PSEN1 mutations

Investigator:

DIAN-T1914

Aim 1:

Aim 1: To identify Differentially Methylated Loci (DML) in ADAD and sporadic AD and neuropath-free controls

Title:

Truncated tau species tau224 and tau368 in CSF and P-tau181 in plasma in familial AD as indicators of pathological brain tau metabolism

Date of Request:

08/14/2019

Status:

withdrawn

ID:

DIAN-T1908

Aim 1:

To examine how novel CSF biomarkers for tau pathology (tau truncated at positions 224 or 368) change with onset of amyloid pathology and tau pathology, as well as clinical disease onset and progression in familial AD

Aim 2:

To examine how plasma P-tau181 changes with onset of amyloid pathology and tau pathology, as well as clinical disease onset and progression in familial AD

Investigator:

Catherine Marquer

Title:

Pharmacological Validation of SERCA Activators for Diabetes Associated ADRD

Date of Request:

05/12/2019
