In vivo, the combination of IF4G3986–994 with poly IC elicited robust anti-tumor immunity, characterized by increased CD8+ T lymphocytes infiltration, reduced regulatory T cells (Tregs) in the tumor microenvironment, elevated systemic Interferon-gamma (IFN-γ) levels, and significant tumor growth inhibition without systemic toxicity. This evidence concerns the gene CD8A and neoplasm.
