Summary: DuoBody-CD40x4-1BB is a novel antibody capable of enhancing antitumor immunity by modulating the functions of immune cells. In vitro and in vivo experiments have demonstrated its ability to enhance dendritic cell and T-cell functions, as well as its biological activity in patients with advanced solid tumors. These findings suggest that targeting CD40 and 4-1BB with an Fc-inert bispecific antibody may be an effective approach for cancer treatment.

Summary: Immune checkpoint therapy (ICT) has the potential to eliminate cancer, but the underlying mechanisms determining its effectiveness are not fully understood. By using high-dimensional single-cell profiling, this study investigates if the T cell landscape in peripheral blood can predict responses to combinatorial targeting of the OX40 costimulatory and PD-1 inhibitory pathways. The findings reveal dynamic activation states of therapy-responsive T cells and emphasize the importance of NK cell receptors and chemokine receptors in therapy-induced anti-tumor immunity.

Summary: The study shows that statins can enhance the immunogenicity of KRAS-mutant tumors by inducing immunogenic cell death and enhancing the cross-priming ability of dendritic cells, thereby stimulating CD8+ T-cell immune responses against the tumors. Combination therapy using statins and other agents can significantly increase the immunogenicity of KRAS(mut) tumors and improve tumor-specific immunity, overcoming resistance to PD-1 blockade therapies and increasing survival rates in KRAS(mut) tumor models.

Summary: This study found that HSP70 plays an important role in PEDV replication, with its overexpression increasing the speed of viral replication, while knockout significantly reduces PEDV protein expression and replication. Furthermore, the study confirmed the crucial role of the PEDV membrane (M) protein in collaboration with HSP70 in viral replication in infected cells.

Summary: Staphylococcus aureus is a pathogen associated with various diseases and the emergence of antibiotic-resistant strains has raised concerns. Developing vaccines may help overcome these resistant strains, but the ability of S. aureus to internalize into cells poses a challenge. This study explores the potential of CD8(+) T cells to recognize and kill S. aureus-infected dendritic cells, paving the way for CD8(+) T cell-based therapies against S. aureus.

Summary: Immune checkpoint inhibitors have significantly changed the standard care for many solid tumor malignancies, but resistance remains common. Adoptive cellular therapy is a rapidly growing form of immunotherapy that shows promise in overcoming resistance mechanisms and has already revolutionized the treatment of hematologic malignancies. The use of ACT in solid tumor malignancies is still in its early stages, with promising therapies under active investigation.

Summary: In this study, we found that inhibiting the activity of scavenger receptor A (SRA) can enhance the immunogenicity of dendritic cells (DCs) in capturing chaperone vaccines targeting melanoma and breast cancer. The downregulation of SRA leads to increased activation of antigen-specific T cells and inhibition of tumor growth. Additionally, we discovered that the administration of a chitosan-siRNA complex can effectively reduce SRA expression on DCs in vitro and in vivo. The combination of this complex with the chaperone vaccine promotes a cytotoxic T lymphocyte response and reprograms the tumor environment. The findings suggest the potential for further optimization of the chitosan-siRNA formulation to enhance the immunotherapeutic benefits of chaperone vaccine.

Summary: The cytomembrane-derived delivery platform is a promising biomimetic strategy for oncotherapy. By fusing mature dendrosomes with redox-responsive nanoparticles, durable and reliable tumor inhibition can be achieved, along with enhanced immunogenicity and immunocyte differentiation. Combination with aPD-L1 further enhances the antitumor effect.

Summary: The CD161-expressing T cell subset identified by the NK cell marker CD161 in humans exhibits enhanced cytotoxic and memory phenotypes, making it a potentially effective candidate for chimeric antigen receptor (CAR) T cell therapy. Gene expression profiling in mice shows up-regulation of cytotoxic markers and innate signaling molecules in CD161-expressing CD8(+)NK1.1(+) T cells, leading to improved protection against tumor and viral infections. Furthermore, human CD8(+)CD61(+) T cells demonstrate heightened killing activity and improved efficacy in CAR therapy targeting solid tumors.

Summary: The study found that curcumin can increase the expression of HSP70 in intestinal Caco-2 cells through transcriptional activation, possibly enhancing cell integrity. The effects of curcumin are regulated by various signaling pathways. This discovery is expected to contribute to a deeper understanding of the regulation of intestinal HSP70 by dietary components.

Summary: In this study, a novel BCG lysate was developed and formulated into a thermosensitive hydrogel. The BCG lysate exhibited enhanced antitumor efficacy and promoted a proinflammatory tumor microenvironment in vivo. The underlying mechanisms of BCG lysate-mediated tumor immunity relied on macrophages (M phi) and dendritic cells (DCs). The BCG hydrogel treatment induced systemic immunity, suppressed lung metastases, and improved survival in melanoma-bearing mice. Furthermore, BCG hydrogel treatment enhanced antigen processing and presentation, and increased the frequency of melanoma-reactive CD8(+) T cells. In human melanoma patients, intralesional-BCG treatment was associated with enhanced M1 M phi, mature DCs, antigen processing and presentation, and increased patient survival.

Summary: This study provides new information on the efficacy of PD-L1-targeted CAR against PD-L1(low) targets. The results show that PD-L1-CAR cells have strong reactivity and cytotoxicity against both PD-L1(high) and PD-L1(low) target cells. Additionally, PD-L1-CAR cells also exhibit potent cytotoxic effects against non-malignant cells.
