Special Issue Information

Dear Colleagues,

Recent findings suggest that the cellular and extracellular materials surrounding cancerous cells in an atypical tumor microenvironment (TME) play a pivotal role in tumor initiation and progression processes. The TME comprises an intricate system involving diverse cell types, including endothelial cells, pericytes, smooth muscle cells, fibroblasts, various inflammatory cells, dendritic cells, and cancer stem cells (CSCs). TME-forming cells dynamically interact with cancerous cells through various signaling mechanisms and pathways. Present-day researchers thus have a particular interest in exploiting these relationships to develop nanotherapeutics. Nanoparticles’ benefits include their ability to passively target through the EPR effect and capacity to be easily be modified with a variety of moieties for active targeting. Moreover, they can utilize the altered tumor environment to promote drug accumulation at tumor sites and modulate the tumor microenvironment by carrying drugs.

This Special Issue welcomes both reviews and original articles shedding light on nanotherapeutics targeting or regulating the tumor microenvironment. Topics of interest include, but are not limited to, the following topics:

  1. Development of the cancer-specific delivery and accumulation of nanotechnology-based systems bearing anticancer drug and diagnostics.
  2. Effectively promoting immune stimulation of infiltrating lymphocytes in the TME to exert cancer chemotherapy effects combined with immunotherapy.
  3. Effectively enhancing the delivery and transfection efficiency of gene drugs to target cells in the TME for precise cancer treatment.
  4. Research and design of biosafety materials for the tumor microenvironment (pH, hypoxic environment, specific cells involved in TME, etc.) to optimize cancer prevention, treatment, and prognosis.
  5. Complex coculture systems (stem cells/immune cells/cancer cells) based on advanced nanomaterials.

Celastrol (Cel), a compound derived from traditional Chinese medicine Tripterygium wilfordii Hook. F, has attracted considerable attention as an anticancer drug. However, its clinical application is limited due to its low bioavailability and potential toxicity. With the advancement of nanoscale metal organic frameworks (MOF), the nano-delivery of drugs can effectively improve those disadvantages. Nevertheless, hydrophobic drugs apparently cannot be encapsulated by the hydrophilic channels of MOF-based drug delivery systems. To address these issues, a new assembly strategy for hydrophobic Cel was developed by coordinating the deprotonated Cel to zeolitic imidazolate framework-8 (ZIF-8) with the assistance of triethylamine (Cel-ZIF-8). This strategy greatly elevates the assembly efficiency of Cel from less than 1% to ca. 80%. The resulted Cel-ZIF-8 remains stable in the physiological condition while dissociating and releasing Cel after a 45-minute incubation in an acidic tumor microenvironment (pH 5.5). Furthermore, Cel-ZIF-8 is proved to be easily taken up by cancer cells and exhibits a better therapeutic effect on tumor cells than free Cel. Overall, the Cel-ZIF-8 provides a novel assembly strategy for hydrophobic drugs, and the findings are envisaged to facilitate the application of Cel in cancer therapies. Full article
