The mechanism of cancer sono-immunotherapy involves two key processes: (i) sonosensitizer-mediated SDT, which induces immunogenic cell death (ICD) and the release of damage-associated molecular patterns (DAMPs), pathogen-associated molecular patterns (PAMPs), and tumor-associated antigens (TAAs); and (ii) immune-oncology drug-mediated remodeling of the tumor immune environment (TIEM), including dendritic cell (DC) maturation, activation of cytotoxic T lymphocytes (CTLs), inhibition of myeloid-derived suppressor cells (MDSCs), polarization of M1 macrophages (M1-Macs), and suppression of regulatory T cells (Tregs).
