Mission Bio's Tapestri® Platform Used to Identify Hidden HIV-infected Cells in Nature Paper
SOUTH SAN FRANCISCO, Calif., Jan. 6, 2023 /PRNewswire/ -- Mission Bio, the pioneer in high-throughput single-cell DNA and multi-omics analysis, announced a new publication in Nature from researchers at the Ragon Institute of MGH, MIT, and Harvard and Brigham and Women's Hospital using Mission Bio's Tapestri® Platform to identify phenotypic signatures of hidden human immunodeficiency virus 1 (HIV-1)-infected immune cells that allow the virus to evade immune response. The team utilized Tapestri®'s proteogenomics capabilities to detect HIV DNA and corresponding surface markers on patients' memory CD4+ T cells for the first time, as well as to develop a fingerprint for latent infection that may guide new treatment approaches.
- Previous research has suggested that host immune cells can slowly deplete these reservoir cells, lending hope to the idea that immunotherapy approaches could someday be used to treat disease.
- In the new paper, the Boston-based teams used single-cell proteogenomic profiling on the Tapestri® Platform to simultaneously evaluate HIV DNA and the phenotype of single unmanipulated, patient-derived cells.
- "This new paper demonstrates the versatility of the Tapestri® Platform," said Todd Druley, MD, PhD, Chief Medical Officer of Mission Bio.
- The paper, " Phenotypic signatures of immune selection in HIV-1 reservoir cells ," published on January 4 in Nature.
