Controlled Inflammation Drives Neutrophil-Mediated Precision Drug Delivery in Heterogeneous Tumors.

Tumor heterogeneity remains a formidable obstacle in targeted cancer therapy, often leading to suboptimal treatment outcomes. This study presents an innovative approach that harnesses controlled inflammation to guide neutrophil-mediated drug delivery, effectively overcoming the limitations imposed by tumor heterogeneity. By inducing localized inflammation within tumors using lipopolysaccharide, it significantly amplify the recruitment of drug-laden neutrophils to tumor sites, irrespective of specific tumor markers.

Chemotherapy is a potent tool against cancer, but drug resistance remains a major obstacle. To combat this, understanding the molecular mechanisms behind resistance in cancer cells and the protein expression changes driving these mechanisms is crucial. Targeting the Ubiquitin-Proteasome System (UPS) has proven effective in treating multiple myeloma and shows promise for solid tumours.

Glioblastoma (GBM) is a highly aggressive adult brain cancer, characterised by poor prognosis and a dismal five-year survival rate. Despite significant knowledge gains in tumour biology, meaningful advances in patient survival remain elusive. The field of neuro-oncology faces many disease obstacles, one being the paucity of faithful models to advance preclinical research and guide personalised medicine approaches.

Gastric cancer (GC) remains a significant global health burden due to its high aggressiveness, early metastasis, and poor prognosis. Despite advances in chemotherapy and targeted therapies, drug resistance remains a major obstacle to improving patient outcomes. Integrins, a family of transmembrane receptors, play a pivotal role in mediating tumor growth, invasion, and drug resistance by interacting with the tumor microenvironment (TME) and regulating signaling pathways such as Wnt/β-catenin, FAK, and MAPK.

Cancer remains one of the most pressing health challenges worldwide. Recently, chimeric antigen receptor (CAR)-T cell therapy has emerged as a promising approach for treating hematological cancers. However, the translation of CAR-T cell therapy to solid tumors faces formidable obstacles, notably the immunosuppressive tumor microenvironment.
