Thank you for your interest in receiving resources from the National NeuroAIDS Tissue Consortium (NNTC).  The NNTC can provide variety of tissues and samples from HIV positive and negative patients. This includes central and peripheral nervous system tissue, CSF, Blood and other organs such as heart, lung, liver, and kidney. Our large array of samples are accompanied by comprehensive histories and clinical data.

AIDS grant deadlines are coming up. A reminder that if you intend to submit an NNTC Request Application in preparation for a grant, please do so within 20 business days of your planned grant submission. The NNTC requires additional time to process request applications during grant cycles. Applications submitted to  the NNTC later than the 20 business days will be processed to the best of our ability, but no guarantee can be made for review and approval prior to your NIH grant submission.

All requests including letters of support require time for initial processing of the application by the Data Coordinating Center (typically 5 business days). In addition, the Allocations Committee requires 10 full business days for review. This review process can extend beyond this timeline if additional shaping of the request is required based on study feasibility and resource availability.

If you wish to request tissues and/or fluids, the NNTC requires that you complete the following Specimen Request Application:

If you only wish to request data, the NNTC requires that you complete the following Data Request Application:

Request Application Submission:

To submit your request, follow the steps below. If you are a new investigator, begin at step 1. If you are a returning investigator, begin at step 3.

  1. You will first need to request an account to access the secure investigator area of the website. To do so, click “Connect With Us” located in the upper right-hand corner of the page.
  2. Enter “Request New Account” in the body field and complete the other required information. You will be emailed instructions on how to access your account typically within 24 hours. Continue following the next steps below.
  3. Log into the NNTC website using the link provided to reset your password.
  4. Click on “Request Review” then “New Application” and follow the directions to upload your request application.
  5. After your request is broadcast to the consortium you can track its status in the review process by clicking on “Request Review” from the menu. A link to your request will appear under the “My Requests” table and you provide supplemental materials as needed using the “Add” button next to your request.

Please be aware that we expect you to uphold the Acknowledgment Agreement that was signed as part of your request application, citing Federal Grant numbers as specified in the agreement.

Review Process:

All requests undergo a review process in the order they are received in. The Data Coordinating Center first processes the application to ensure clarity and completeness prior to broadcasting to the NNTC Allocations Committee. Please note that following the broadcast, the committee requires at least two weeks to complete their review of each specimen and/or letter of support request. Upon approval, the letter or specimens will be shipped to your laboratory as such specimens become available to the Consortium. The Consortium charges no fee for providing this service, however the cost of shipping will be assumed by the recipient. We preferably ship via FedEx; however we can work with investigators if alternate carriers are necessary.  We request that you provide us with your FedEx account number in the Specimen Request Application.
