This study explores the immunomodulatory effects of amlodipine, a widely used antihypertensive, on dendritic cell (DC) maturation and anti-tumor immunity. Using flow cytometry, ELISA, and single-cell RNA sequencing, we found that amlodipine significantly promotes DC maturation, evidenced by increased CD80 and CD86 expression and upregulation of genes like CCL4 and Saa3 related to T cell activation. Furthermore, when amlodipine was administered in conjunction with indocyanine green or doxorubicin therapy in murine models of 4T1 breast cancer and CT26 colon cancer, we observed a notable activation of CD8 T cells.

However, the Golgi-localized APYs, which help control glycosylation, have rarely been studied. Here, we identified AtAPY1, a gene encoding an NTPDase in the Golgi apparatus, which is required for cell wall integrity and plant growth under boron (B) limited availability.

Immune checkpoint blockade therapy, as a promising alternative therapy, faces limitations in combating tumor recurrence due to the low immune response rate. In this study, we developed an implantable photo-responsive self-healing hydrogel loaded with MoS nanosheets and the immunoadjuvant R837 (PVA-MoS-R837, PMR hydrogel) for generation of tumor-associated antigens at the post-surgical site of the primary tumor, enabling sustained and effective activation of the immune response.
