The Tumor Microenvironment02:17

The Tumor Microenvironment

6.6K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Tumor Immunotherapy01:27

Tumor Immunotherapy

524
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.

Summary

Computational models reveal how collagen alignment in tumors aids immune escape. This study shows that highly aligned collagen fibers in late-stage squamous cell carcinomas can protect tumors from immune cells, impacting disease progression.

Area of Science:

  • Oncology
  • Computational Biology
  • Immunology

Background:

  • Directly observing immune cell behavior in human tumors is challenging.
  • Collagen formation is hypothesized to be an immune escape mechanism, but its interaction with immune cells is unclear.
  • Late-stage squamous cell carcinomas exhibit highly aligned collagen fibers.

Conclusions:

  • Collagen fiber alignment plays a significant role in tumor immune escape.
  • The length scale of tumor-immune interactions is a critical factor influencing tumor growth and infiltration.
  • Computational modeling offers valuable insights into complex tumor-immune dynamics and disease progression.
