Abstract:
Stem cell research has led to the discovery of glioma stem cells (GSCs), and because these cells are resistant to chemotherapy and radiotherapy, analysis of their properties has been rapidly pursued for targeted treatment of malignant glioma. Recent studies have also revealed complex crosstalk between GSCs and their specialized environment (niche). Therefore, targeting not only GSCs but also their niche may be a principle for novel therapies of malignant glioma. One possible novel strategy for targeting GSCs and their niches is immunotherapy with different antitumor mechanism(s) from those of conventional therapy. Recent clinical studies of immunotherapy using peptide vaccines and antibodies have shown promising results. This review describes the recent findings related to GSCs and their niches, as well as immunotherapies for glioma, followed by discussion of immunotherapies that target GSCs for the treatment of malignant glioma.
Insights
Targeting glioma stem cells (GSCs) and their niche with immunotherapy offers a novel approach for malignant glioma treatment. This review explores GSCs, their niches, and promising immunotherapies for improved patient outcomes.
Area of Science:
- Neuro-oncology
- Cancer Stem Cell Biology
- Immunotherapy
Background:
- Glioma stem cells (GSCs) are key drivers of malignant glioma, exhibiting resistance to conventional therapies.
- Complex interactions between GSCs and their microenvironment (niche) influence tumor progression and treatment resistance.
Purpose of the Study:
- To review recent findings on glioma stem cells and their niches.
- To discuss the potential of immunotherapy targeting GSCs and their niches for malignant glioma treatment.
Main Methods:
- Literature review of recent studies on GSCs, their niches, and immunotherapies for glioma.
- Analysis of preclinical and clinical data on immunotherapy strategies.
Main Results:
- GSCs and their niche crosstalk is crucial for glioma pathogenesis.
- Immunotherapy, including peptide vaccines and antibodies, shows promising results in clinical studies.
Conclusions:
- Targeting both GSCs and their niche is a promising therapeutic strategy.
- Immunotherapy represents a novel approach with distinct antitumor mechanisms for malignant glioma.
