Cancer cell-derived extracellular vesicles (CEVs), a novel type of therapeutic agent in cancer treatment, can be prepared from the autocrine secretion of various cancer cells, the direct extraction of cancer cells and the combination of cancer cell-derived membranes with advanced materials. With various bioactive molecules, exosomes are produced by cells for intercellular communication. Although cancer cell-derived exosomes are known to inhibit tumor apoptosis and promote the progression of cancer, researchers have developed various innovative strategies to prepare anti-tumor vesicles from cancer cells. With current strategies for anti-tumor vesicles, four different kinds of CEVs are classified including irradiated CEVs, advanced materials combined CEVs, chemotherapeutic drugs loaded CEVs and genetically engineered CEVs. In this way, CEVs can not only be the carriers for anti-tumor drugs to the target tumor area but also act as immune-active agents. Problems raised in the strategies mainly concerned with the preparation, efficacy and application. In this review, we classified and summarized the current strategies for utilizing the anti-tumor potential of CEVs. Additionally, the challenges and the prospects of this novel agent have been discussed.

Cutaneous photoaging, induced by chronic exposure to ultraviolet (UV) radiation, typically manifests as alterations in both the physical appearance and functional properties of the skin and may predispose individuals to cancer development. Recent studies have demonstrated the reparative potential of exosomes derived from mesenchymal stem cells in addressing skin damage, while specific reports highlight their efficacy in ameliorating skin photoaging. However, the precise role of exosomes derived from human hair follicle mesenchymal stem cells (HFMSC-Exos) in the context of cutaneous photoaging remains largely unexplored.

Senescence is a non-proliferative, survival state that cancer cells can enter to escape therapy. In addition to soluble factors, senescence cells secrete extracellular vesicles (EVs), which are important mediators of intercellular communication. To explore the role of senescent cell-derived EVs (senEVs) in inflammatory responses to senescence, we developed an engraftment-based senescence model in wild-type mice and genetically blocked senEV release in vivo, without significantly affecting soluble mediators.

Objective: This study investigated the clinical significance of mutations in patients with distant metastatic follicular cell-derived thyroid cancer (FDTC).
Methods: This study included 310 Chinese patients with distant metastatic FDTC. We analyzed the interactions between mutations and other gene alterations and compared the clinicopathological characteristics of patients with pathogenic (P) or likely pathogenic (LP) mutations (n=9), other gene alterations (n=253), and no gene alterations (n=37).

Newcastle disease virus (NDV) has shown encouraging effectiveness in , , and in early clinical trials as a viro-immunotherapy for pancreatic cancer. Previously, NDV used in clinical trials was produced in embryonated chicken eggs; however, egg-produced viruses are known to be partly neutralized by the human complement system when administered intravenously. Here, an NDV variant (NDV F0) was generated for production in mammalian cells, without passage in eggs.

Neurotransmitters are increasingly recognized to play important roles in limiting anti-tumor immunity. N-acetyl-aspartyl-glutamate (NAAG) has been extensively studied in neurological disorders; however, its potential role in restricting anti-tumor immunity has not been investigated. Here, we demonstrated that NAAG or its synthetase RimK-like family member B (RIMKLB) significantly disrupted anti-tumor immunity by rewiring the myeloid progenitor differentiation of polymorphonuclear myeloid-derived suppressor cells (PMN-MDSCs), which in turn promoted breast cancer growth and metastasis.
