80–90% of cancer are carcinomas, or cancers that form from epithelial tissue. This tissue is not vascularized, which prevents tumors from growing greater than 2mm in diameter without inducing new blood vessels. Angiogenesis is upregulated to feed the cancer cells, and as a result the vasculature formed differs from that of normal tissue. WebSep 7, 2024 · In cases of cancer, the tumors are often found in an altered metabolic state, which leads to anomalous extracellular chemical composition, such as acidosis (low pH), hypoxia (low oxygen)...

Background: Treatment of immunologically cold tumors is a major challenge. IL-12 can activates both innate and adaptive immunity to elicit strong antitumor immunity. Nevertheless, the poor pharmacokinetic and severe side effects of IL-12 limit the application. We have recently developed pH-sensitive polymeric micelles loading IL-12 (IL …
