Fc-competent TIGITx4-1BB bispecific antibody exerts potent long-lasting antitumor activity by potentiating CD8+ T cell activity and Fc{gamma} receptor-mediated modulation of the tumor microenvironment

Background
TIGIT was identified as a target immune checkpoint for overcoming resistance to PD-(L)1-blocking antibodies. However, the clinical efficacies of TIGIT antibodies were moderate in monotherapy and mixed in combination with PD-(L)1 antibodies….

Disruption of GPSM1/CSF1 signaling reprograms tumor-associated macrophages to overcome anti-PD-1 resistance in colorectal cancer

Background
Immune checkpoint blockade (ICB) therapies, particularly anti-PD-1, benefit only a limited subset of colorectal cancer (CRC) patients. G-protein signaling modulator 1 (GPSM1) is implicated in immunity and oncology, yet its role in regulatin…

Association of 5{alpha}-reductase inhibitor prescription with immunotherapy efficacy in metastatic renal cell carcinoma: a multicenter retrospective analysis

Background
Immune checkpoint inhibitors (ICIs) have revolutionized the treatment of metastatic renal cell carcinoma (mRCC), but response rates remain heterogeneous, and reliable predictive biomarkers are lacking. Recent studies suggest that androgen r…

Hyperleukocytosis in a neuroblastoma patient after treatment with natural killer T cells expressing a GD2-specific chimeric antigen receptor and IL-15

The ability of immune cells to expand numerically after infusion distinguishes adoptive immunotherapies from traditional drugs, providing unique therapeutic advantages as well as the potential for unmanageable toxicities. Here, we describe a case of l…
