However, the most surprising finding in our work is that these potent cells are strongly inhibited in tumor models that recapitulate the complexity of the tumor microenvironment,” said UNC Lineberger's Gianpietro Dotti, MD, the paper’s corresponding author. “In particular, tumor-associated macrophages seem to have a potent inhibitory effect on CAR-T cells. CAR-NKT seem capable to avoid the inhibitory effects of macrophages since they can directly target them.” Credit UNC Lineberger Comprehensive Cancer Center Usage Restrictions None License Original content Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news releases posted to EurekAlert! by contributing institutions or for the use of any information through the EurekAlert system.
