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.

Galectin-3 as a prognostic biomarker to monitor Autosomal dominant Alzheimer's Disease's progression
We aim to evaluate if gal3 levels are elevated in ADAD and if they might track the progression of AD pathology.
We want to compare the levels of gal3 with the levels of the classic biomarkers (amyloid-beta 42, total tau, p-tau (181, 217, etc), neurofilaments, precuneus SURV and PIB-Pet) as well as with global cognitive test (MMSE) and clinical measures (CDR total and SB) scores from the DIAN-obs
Study of endolysosomal alterations (including exosomes) in brain cells cultures derived from fDA iPSC lines and isogenic controls
Determine the effect of mutant APP on exosome dynamics in CNS cells in human AD models.

High-resolution multiplex localization of Alzheimer’s disease risk and resilience factors
Determine the expression levels, localization, and co-localization patterns of proteins in the m109 and BIN1 protein clusters in relation to synaptic markers. Synaptic changes have long been recognized to be tightly linked to AD severity (9). We will determine the expression patterns of the two protein clusters relative to excitatory and inhibitory synapses using antibodies specific for excitatory synapses (e.g., AMPA- and NMDA-type receptors and PSD-95), inhibitory synapses (e.g., vesicular GABA transporter/VGAT and gephyrin), and presynaptic terminals (e.g., synapsin).
Determine the expression levels, localization, and co-localization patterns of proteins in the m109 and BIN1 protein clusters in relation to AD pathology. Probable AD is confirmed at autopsy by the presence of amyloid plaques and tangles (10). We will determine the expression patterns of the two protein clusters as a function of proximity to regions with amyloid plaques (using a 6E10 antibody), neurofibrillary tangles (using a tau13 antibody), astrocytes (using a GFAP antibody), and microglia (using an Iba1 antibody).
