In wild-type <a href="/wiki/C57BL/6" title="C57BL/6">C57BL/6</a> mice, anti-CTLA-4 treatment resulted in tumor rejection in 80 to 90% of subjects, but in gene-targeted mice that were deficient for either ICOS or its <a href="/wiki/Ligand" title="Ligand">ligand</a> (<a href="/wiki/ICOSLG" title="ICOSLG">ICOSLG</a>), the efficacy was less than 50%. An agonistic stimulus for the ICOS pathway during anti-CTLA-4 therapy resulted in an increase in efficacy that was about four to five times as large as that of control treatments. This combination therapy incorporating ICOS costimulation and CTLA-4 blockade effectively remodels tumor-associated macrophages (TAMs) towards an antitumor phenotype, demonstrating promising
