Kinins in Glioblastoma Microenvironment

Area of Science:

• Neuro-oncology
• Cancer Biology
• Stem Cell Biology

Background:

• Tumour progression involves complex interactions between cancer cells, cancer stem cells, and stromal cells.
• Mesenchymal stem cells (MSCs) can migrate to tumours and differentiate, potentially influencing tumour growth.
• Glioblastoma (GBM) has limited therapeutic options, making MSCs a potential cell therapy tool.

Purpose of the Study:

• To review the interactions between MSCs and glioblastoma cells within the tumour microenvironment.
• To highlight the role of kinin signalling and kinin receptors in glioblastoma progression.
• To explore the potential of targeting kinin signalling for glioblastoma therapy.

Main Methods:

• Literature review of studies on MSC-glioblastoma interactions.
• Analysis of the role of microenvironmental cues and kinin receptor signalling.
• Examination of kinin's influence on blood-brain barrier drug transfer and angiogenesis.

Main Results:

• MSCs can either inhibit or support glioblastoma progression.
• Cancer cells exhibit differential responses to microenvironmental cues and kinin signalling.
• Kinin receptor expression increases with glioblastoma malignancy, suggesting a significant role for kinin signalling.

Conclusions:

• Kinin signalling is a crucial, yet under-explored, aspect of the glioblastoma microenvironment.
• Kinins impact drug delivery across the blood-brain barrier and tumour angiogenesis.
• Kinin antagonists show promise as anti-invasive agents for adjuvant glioblastoma therapy.
