Steatotic liver disease (SLD), which is associated with increased risk of cancer-related mortality, needs timely and cost-effective detection. Although liver biopsy remains the diagnostic gold standard, its invasiveness and high-cost limit widespread use. Ultrasound is a practical and affordable alternative. We evaluated inter- and intra-observer agreement for ultrasound-based diagnosis of SLD using images from the Chile Biliary Longitudinal Study (Chile BiLS), a cohort of women with gallstones. These women have a high burden of obesity and related metabolic disorders, putting them at higher risk for SLD. A radiologist (observer 1) reviewed a randomly selected subset of 425 baseline images and …

Diffuse mesothelioma (DM) is a rare but highly aggressive and treatment resistant neoplasm with low survival rates. Effective therapeutic strategies are limited, and resistance to treatment is a major obstacle. Myeloid Cell Leukemia (MCL)-1 and B-cell leukemia (BCL)-xL are anti-apoptotic B-cell lymphoma 2 (Bcl-2) family proteins that block cell-intrinsic apoptosis through interactions on the mitochondrial outer membrane which contribute to therapeutic resistance.

We investigated whether B-cell homology domain (BH)-3 profiles were consistent between intra-patient fresh tumor sample, patient-derived cells (PDC), and patient-derived xenografts (PDX) by BH3 profiling; we observed striking consistency which enabled cross model comparisons. Next, we co-targeted BCL-xl …

Faculty, Staff and Students Publications

Human norovirus (HuNoV) causes acute gastroenteritis in immunocompetent hosts and chronic infection in immunocompromised individuals. Many recent studies of replication and innate immune responses following HuNoV infection have utilized epithelium-only human intestinal enteroids (HIEs), which lack immune cells. Here, we utilized an ex vivo enteroid-macrophage coculture model consisting of HIEs and different subtypes of human peripheral blood mononuclear cell-derived macrophages to better recapitulate in vivo gut biology and explore the role of macrophages in HuNoV replication and pathogenesis. We show that HuNoV infection in HIEs polarized on Transwells leads to bilateral release of the viral genome, with predominant apical virus …

MHC class I polypeptide-related sequence B (MICB) is a ligand for NKG2D. We have shown NK cells are central to lung transplant acute lung injury (ALI) via NKG2D activation, and increased MICB in bronchoalveolar lavage predicts ALI severity. Separately, we found a MICB polymorphism (MICBG406A) is associated with decreased ALI risk. We hypothesized this polymorphism would protect against severe SARS-CoV-2 respiratory disease. We analyzed 1,036 patients hospitalized with SARS-CoV-2 infection from IMPACC. Associations between MICBG406A and outcomes were determined by linear regression or Cox proportional hazards models. We also measured immune profiles of peripheral blood and the upper and lower …
