Insights

Small extracellular vesicles (SEVs) show promise as cancer biomarkers and drug delivery vehicles. Further research is needed to overcome challenges for their clinical use in cancer detection and therapy.

Area of Science:

  • Cell biology
  • Oncology
  • Biotechnology

Background:

  • Extracellular vesicles (EVs), including small extracellular vesicles (SEVs), are cell-derived particles involved in physiological and pathophysiological processes.
  • SEVs play roles in cancer growth and metastasis, but these are not fully understood.
  • SEVs are being explored as a drug delivery platform for anticancer agents due to their endogenous nature.

Purpose of the Study:

  • To review the use of cancer-related SEVs as biomarkers for early cancer detection and outcome prediction.
  • To summarize preclinical and clinical studies on SEV-based cancer therapies.
  • To discuss challenges and potential solutions for the clinical implementation of SEVs in oncology.

Main Methods:

  • Literature review of studies on SEVs in cancer.
  • Analysis of preclinical and clinical trial data for SEV-based therapies.
  • Examination of clinical trial registries (FDA and Chinese Clinical Trials Registry).

Main Results:

  • SEVs show potential as biomarkers for early cancer detection and predicting treatment outcomes.
  • SEV-based therapies have demonstrated promise in preclinical and clinical studies.
  • Several challenges impede the clinical application of SEVs, requiring further investigation.

Conclusions:

  • Cancer-related SEVs hold significant potential as diagnostic biomarkers and therapeutic agents.
  • Addressing current challenges in SEV biology and application is crucial for clinical translation.
  • Further research and clinical trials are necessary to fully realize the potential of SEVs in cancer care.

Overview of Exosomes01:36

Overview of Exosomes

Exosomes are stable, lipid bilayer-enclosed vesicles capable of crossing biological barriers. They can carry a wide range of molecules required for intercellular communication. Once exosomes are released from the cell where they originated, they enter a recipient cell through various pathways such as fusion, receptor-mediated endocytosis, macropinocytosis, and phagocytosis.
Stahl et al. discovered exosomes in 1983, but the exosomes were initially considered waste products released from the...

Cancer Vaccines01:30

Cancer Vaccines

Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Cancer Stem Cells and Tumor Maintenance

Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Tumor Immunotherapy01:27

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
