Please join us in Congratulating the newly funded 2023 NIH NIDDK HIRN Gateway Investigators. This initiative is designed to support a robust pipeline of innovative projects and talented new investigators in T1D research.

• NIDDK and NIDDK Central Repository are hosting a data-centric challenge with the goal of generating an “AI-ready” dataset that can be used for future data challenges and to produce methods that can be used to enhance the AI-readiness of NIDDK data. Participants will enhance data on T1D available through the NIDDK Central Repository from the TEDDY and TrialNet studies.
  

  Phase 1 open until November 30, 2023.
  Challenge runs from December 1, 2023 – January 10, 2024.

Biomedical devices comprise a major component of modern medicine. However, immune mediated fibrosis and rejection can limit their function over time. Although mouse models of fibrosis such as the immunocompetent C57BL/6 strain can generate robust fibrotic responses to implanted devices, murine and human immune systems can differ greatly and results in mice do not always translate to humans. The fibrotic response observed in non-human primates resembles that observed in humans, but this model carries with it financial and ethical concerns. Doloff et al have now developed a small animal model of fibrosis using human immune system engrafted immunodeficient mice, i.e., “humanized mice”. This small animal model recapitulates the cellular and molecular fibrotic response observed in humans. These humanized mice can be used to investigate the mechanisms of the human fibrotic response and approaches to ameliorate the response. Moreover, this model can be used to test human specific therapies that cannot be tested in immunocompetent mice.

The HIRN Year 5 & Year 6 Executive Summary Report is now available online! The report reflects significant HIRN breakthroughs, developments and advancements across the entire network. This 2-year report reflects activity from October 2018 through September 2020.
