Blake Wiedenheft, PhD: CRISPR-Based Recombinant RNA Technologies for Engineering the Human Transcriptome
Dr. Blake Wiedenheft, a professor at Montana State University, presents his research on CRISPR-based recombinant RNA technologies for engineering the human transcriptome. His team is exploring a novel use of CRISPR systems to edit RNA instead of DNA, addressing the challenges of DNA editing in cells without nuclei or where DNA editing is toxic or ethically problematic. They demonstrated that introducing the type III CRISPR system into human cells can effectively edit RNA, knocking down 95% of targeted RNA and repairing the remaining transcripts in a programmable way. This approach holds potential for correcting genetic diseases by repairing RNA to bypass premature stop codons, as evidenced by their success in restoring functional CFTR protein in cystic fibrosis models.
Oliver Nakano-Baker, PhD: Nose-on-a-Chip: A Platform for Rapid, Breath-Based Diagnostics
Dr. Oliver Nakano-Baker introduces a groundbreaking biohybrid sensor platform aimed at detecting diseases through exhaled breath. Inspired by trained dogs’ ability to detect COVID-19 and cancer from volatile organic compounds (VOCs), this technology leverages carbon nanotube transistors and surface-binding peptide molecules derived from olfactory proteins. Developed through molecular machine learning, these sensors target specific VOCs associated with various conditions. Validated to detect disease markers at parts-per-billion concentrations in human breath, this “nose-on-a-chip” technology promises mobile breathalyzers capable of rapid diagnoses for viral and bacterial infections, early-stage cancers, and monitoring blood glucose levels, potentially revolutionizing healthcare diagnostics.
David Koelle, MD: A New Way to Measure (T cells) Immune Responses to Vaccination
Dr. David Koelle from the University of Washington discusses a novel method for assessing immune responses to vaccination using T cell receptor (TCR) sequencing. This approach measures changes in T cell populations after vaccination, revealing new antigen-specific T cells that appear in response to the vaccine. The method, validated with data from COVID-19 vaccines, offers advantages over traditional techniques by being cost-effective and requiring simpler sample handling. However, challenges include proprietary data sets and the need for public databases. This technique holds promise for broad applications in monitoring vaccine efficacy, though it may be less suited for personalized cancer vaccines due to individual-specific T cell responses.
