Optimized BCMA/CS1 bispecific TRuC-T cells secreting IL-7 and CCL21 robustly control multiple myeloma.

Introduction: Challenges remain in reducing antigen escape and tumor recurrence while CAR-T cell therapy has substantially improved outcomes in the treatment of multiple myeloma. T cell receptor fusion construct (TRuC)-T cells, which utilize intact T cell receptor (TCR)-CD3 complex to eliminate tumor cells in a non-major histocompatibility complex (MHC)-restricted manner, represent a promising strategy. Moreover, interleukin-7 (IL-7) is known to enhance the proliferation and survival of T cells.

Exploring the efficacy of (R)-PFI-2 hydrochloride in mitigating noise-induced hearing loss by targeting NLRP3 inflammasome and NF-κB pathway to reduce inner ear inflammation.

Noise-induced hearing loss (NIHL) is primarily driven by inflammatory processes within the cochlea, where noise exposure triggers the activation of the NOD-like receptor protein 3 (NLRP3) inflammasome, leading to an inflammatory cascade. The interaction between increased NLRP3 expression and NF-κB activity can further amplify cochlear inflammation. Our findings reveal that (R)-PFI-2 hydrochloride, a selective inhibitor of the SETD7 enzyme, effectively inhibits the activation of the cochlear NF-κB pathway, suppresses the release of pro-inflammatory factors, and prevents inflammasome assembly.

Enfortumab vedotin plus pembrolizumab for previously untreated locally advanced or metastatic urothelial carcinoma: a cost-effectiveness analysis.

Background: Both the antibody-drug conjugate (ADC) enfortumab vedotin (EV) and programmed death-1 inhibitor pembrolizumab have been shown to provide survival benefits in patients previously treated with locally advanced or metastatic urothelial carcinoma (la/mUC). Cost-effectiveness is necessary to consider whether the increased efficacy of the two therapies will lead to higher prices for first-line treatment of previously untreated la/mUC.

Objectives: To guide the choice of EV plus pembrolizumab or chemotherapy for patients with previously untreated la/mUC.

Progress in understanding the regulatory mechanisms of immune checkpoint proteins PD-1 and PD-L1 expression.

Programmed Death Protein-1 (PD-1) is a cell surface receptor that serves as a checkpoint for T cells, playing a pivotal role in regulating T-cell apoptosis. The binding of PD-1 to its ligand, Programmed Death Ligand 1 (PD-L1), inhibits anti-tumor immunity by suppressing T-cell activation signals. Indeed, the PD-1/PD-L1 pathway governs the induction and maintenance of immune tolerance within the tumor microenvironment.
