The Tumor Microenvironment02:17

The Tumor Microenvironment

6.5K
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...

Metastasis02:30

Metastasis

5.5K
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Area of Science:

  • Oncology
  • Immunology

Background:

  • The lung tumor microenvironment (TME) is a complex network of cells and molecules.
  • This environment significantly influences tumor progression and treatment resistance.
  • Lung cancer cells and their stroma can suppress immune responses from natural killer (NK) cells and T cells.

Purpose of the Study:

  • To discuss the intricate cellular and molecular interactions within the lung TME.
  • To identify how these interactions regulate tumor progression and immune evasion.
  • To provide insights into potential therapeutic targets for lung cancer.

Main Methods:

  • Review of current literature on lung TME composition and function.
  • Analysis of signaling pathways and molecular mediators within the TME.
  • Discussion of immune evasion mechanisms employed by lung tumors.

Main Results:

  • Lung TME comprises diverse cells (immune, stromal) and secreted factors (growth factors, exosomes, epigenetic regulators, cytokines).
  • These components create a complex web that actively dampens anti-tumor immune responses.
  • Tumor cells and stromal elements collaborate to promote tumor growth and resistance.

Conclusions:

  • Understanding lung TME interactions is crucial for developing effective lung cancer therapies.
  • Targeting specific cellular and molecular components of the TME may overcome treatment resistance.
  • Elucidating these multifaceted interactions can lead to novel therapeutic strategies for lung malignancies.
