  • Combination therapy with cetirizine and anti-PD-1 antibody reduces colitis-induced colon tumor formation in mice.
  • Cetirizine enhances the antitumor effects of anti-PD-1 antibody, leading to reduced tumor volume and increased immune activation.
  • The combination therapy results in elevated CD3+ T-cell infiltration into tumors and downregulation of genes like Vegfa, Mmp9, Il10, and Cd80.
  • In vitro studies show cetirizine suppresses Mmp9 in CT26 cells, Il10 in macrophages, and VEGFA in endothelial cells.
  • The findings suggest cetirizine reshapes the tumor microenvironment, improving the efficacy of immune checkpoint inhibitors.
