Splet01. mar. 2024 · The activation marker CD137 can be used to select a population of cells from healthy donor PBMC. CD137-selected cells can be expanded in vitro and induce efficient killing of AML cells compared to the subset of PBMCs with no CD137 expression. Splet03. jul. 2024 · Background The successful ex vivo expansion of T-cells in great numbers is the cornerstone of adoptive cell therapy. We aimed to achieve the most optimal T-cell expansion condition by comparing the expansion of T-cells at various seeding densities, IL-2 concentrations, and bead-to-cell ratios. we first expanded the peripheral blood …

Splet21. apr. 2014 · Antibody-dependent cellular cytotoxicity (ADCC) is one of the important mechanisms of action of the targeting of tumor cells by therapeutic monoclonal antibodies (mAbs). Among the human Fcγ receptors (FcγRs), FcγRIIIa is well known as the only receptor expressed in natural killer (NK) cells, and it plays a pivotal role in ADCC by IgG1 … SpletT cell activation via the αβ-T cell receptor (TCR complex) is required for in vitro expansion. Treatment of T cells with monoclonal anti-CD3 antibodies and anti-CD28 antibodies provide a co-stimulatory signal that engages the TCR which can be used for antigen-induced …
