Background: Ultrasound has been widely used in clinical diagnosis because it is noninvasive, inexpensive, simple, and reproducible. With the development of molecular imaging, material science, and ultrasound contrast agents, ultrasound-targeted delivery technology has emerged. The interaction of ultrasound and molecular probes can be exploited to change the structures of cells and tissues in order to promote the targeted release of therapeutic substances to local tumors. The targeted delivery of drugs, genes, and gases would not only improve the efficacy of tumor treatment but also avoid the systemic toxicity and side effects caused by antitumor treatments. This technology was recently applied in clinical trials and showed enormous potential for clinical application. Objective: This article briefly introduces the characteristics of the tumor microenvironment and the principle of ultrasound-targeted delivery technology. To present recent progress in this field, this review focuses on the application of ultrasound-targeted delivery technology in tumor-targeted therapy, including drug delivery, gene transfection, and gas treatment. Results: The results of this study show that ultrasound-targeted delivery technology is a promising therapeutic strategy for tumor treatment. Conclusion: Ultrasound-targeted delivery technology shows promise with regard to cancer treatment.

Abstract Abstract 4508 Systemic administration of immunotherapeutics often give rise to severe side effects. A local deposition, using secretory lysosomes of hematopoietic cells as vehicles for delivery, may overcome this problem. Our research regarding sorting mechanisms of granule proteins have led to a new therapeutic idea – targeted therapy with hematopoietic cells as carriers. Exogenous proteins are expressed, and the gene product is directed for secretory lysosome or granule storage. These organelles are unique storage compartments in neutrophils for biological active proteins, designated for inflammatory foci. The exogenous proteins, would accordingly, be locally released at the site of inflammation. Our model construct, soluble TNF receptor 1 (sTNFR), can be directed for storage by adding a transmembranous region and a sorting signal. We have earlier shown that this construct, retrovirally expressed in murine hematopoietic progenitor cells, are destined for granule targeting. Furthermore, we have transplanted transduced murine progenitor cells with modified granule content, and found stable expression and inducible release of sTNFR1 in vivo. Our goal is cell linage specific expression in order to selectively express sTNFR1 with a transmembranous region and a signal peptide for granule targeting. To achieve this, lactoferrin, perforin and MPO promoters, including regulatory elements, have been inserted into vectors (we use a retroviral vector with self-inactivating LTRs). The vectors is retrovirally transduced into murine hematopoietic progenitor cells, and the cells are cultured during cytokine driven differentiation and analyzed by FACS and Western blotting. Our results suggest that a concept of using secretory organelles of hematopoietic cells as vehicles for therapeutic agents in vivo may become feasible. It will be possible to test this principle by experiments in animal models of inflammatory and malignant diseases. Likewise, development of this concept may give new information on secretory lysosome function and secretion at inflamed/malignant sites. Disclosures: No relevant conflicts of interest to declare.
