Knockdown of Chitinase 3-Like-1 Inhibits Cell Proliferation, Promotes Apoptosis, and Enhances Effect of Anti-Programmed Death Ligand 1 (PD-L1) in Diffuse Large B Cell Lymphoma Cells.

Abstract excerpt

BACKGROUND Enzymatically inactive chitinase-like protein CHI3L1 is overexpressed in diffuse large B cell lymphoma (DLBCL) patients with PD-L1 imbalance and promotes tumor progression in the microenvironment. Based on this, we investigated how CHI3L1 acts on the proliferation and apoptosis of DLBCL and whether there is a synergy of CHI3L1 in combination with anti-PD-L1 antibodies in vivo.
