We discovered that attenuated Salmonella after intravenous injection would proliferate within various types of solid tumors but show rapid clearance in normal organs, without rendering notable toxicity. Bacteria-induced inflammation would trigger thrombosis in the infected tumors by destroying tumor blood vessels. Six types of tested tumors would all turn into darkened color with strong near-infrared absorbance, as observed by photoacoustic imaging. Under laser irradiation, those bacterial-infected tumors would be effectively ablated. Because of the immune-stimulation function, such bacteria-based photothermal therapy (PTT) would subsequently trigger antitumor immune responses, which could be further enhanced by immune checkpoint blockade to effectively suppress the growth of abscopal tumors. A robust immune memory effect to reject rechallenged tumors is also observed after bacteria-based PTT. Our work demonstrates that bacteria by themselves could act as a tumor-specific PTT agent to enable photoimmunotherapy cancer therapy to inhibit tumor metastasis and recurrence.

Physical And Chemical

Gold nanoparticles (AuNPs) are promising biomedical agents in terms of both imaging and therapy, exhibiting excellent physical and chemical characteristics. The actions of AuNPs can be remotely controlled using strong near-infrared (NIR) light, associated with minimal lateral invasion. Employing the photoacoustic (PA) principle, AuNPs integrate imaging and temperature control, affording both diagnosis and treatment mediated by NIR light. We here review recent progress in the theranostic field employing AuNPs to both PA and photothermal ends.
