Antibody-mediated Inhibition of Global HLA/LILR Interactions Breaks Innate ImmuneSystemTolerance and Unleashes Potent Anti-Tumor Immunity
Ontology highlight
ABSTRACT: We have conducted a study to investigate how blocking HLA/LILR affects the activation of immune cells in the tumor microenvironment. We perfused a freshly isolated primary colon cancer biopsy sample with hIgG1 LALAPG or DX17 LALAPG for 48 hours. We then isolated CD45+ leukocytes from the tumor sample using magnetic cell sorting. Subsequently, we processed the resulting tumor-infiltrating lymphocytes (TILs) for single-cell RNA-seq and Cite-seq analysis. We compared the transcriptomes of NK cells, monocytes, and memory T cells under the two different culture conditions
