Pre-Induced ICD Membrane-Coated Carrier-Free Nanoparticles for the Personalized Lung Cancer Immunotherapy.

Immunotherapy is a required adjuvant method in lung cancer therapy clinically. The single immune adjuvant failed to show the expected clinical therapeutic efficacy due to its rapid drug metabolism and inability to accumulate in the tumor site efficiently. Immunogenic cell death (ICD) is a new anti-tumor strategy combined with immune adjuvants.

TRIM15 forms a regulatory loop with the AKT/FOXO1 axis and LASP1 to modulate the sensitivity of HCC cells to TKIs.

For patients with advanced or metastatic Hepatocellular carcinoma (HCC) who are not suitable for surgical resection, systemic therapy has been considered to be the standard treatment. In recent years, a small subset of patients with unresectable HCC have been benefit from tyrosine kinase inhibitors (TKIs), and the overall survival time of these patients is significantly increased. However, all responders ultimately develop resistance to TKI treatment.
