CTLA-4 Inhibitors Market Insights: A Comprehensive Overview

Cytotoxic T-Lymphocyte Associated Protein 4 (CTLA-4) is an immune checkpoint protein that downregulates immune responses. CTLA-4 inhibitors are designed to block this protein, thereby enhancing the immune system's ability to attack cancer cells. By preventing the interaction between CTLA-4 and its ligands, these drugs facilitate a more robust anti-tumor response, making them a cornerstone in cancer immunotherapy.
