The Tumor Microenvironment02:17

The Tumor Microenvironment

8.0K
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

6.7K
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...

Chemotaxis and Direction of Cell Migration01:21

Chemotaxis and Direction of Cell Migration

5.9K
Cells can detect chemical cues in their environment and reorganize the cytoskeleton to migrate toward them or away from them. This directional migration, called chemotaxis, is essential during embryogenesis and development, immune response, tissue repair and regeneration, and reproduction. These chemical cues can either attract or repel the cell's movement. For example, axon development is determined by a combination of chemoattractants and chemorepellents that direct the growing axon...

Area of Science:

  • Oncology
  • Immunology

Background:

  • The tumor microenvironment (TME) comprises malignant and non-malignant cells, plus soluble mediators.
  • Tumor-specific chemokines and chemotactic factors dictate leukocyte infiltration and activation within the TME.
  • Tumor-associated immune cells interact with stromal cells, impacting tumor progression and dissemination.

Purpose of the Study:

  • To review the current understanding of tumor-associated immune cells in tumor growth and spread.
  • To highlight the role of chemotactic factors in immune cell recruitment and activation within tumors.

Main Methods:

  • Literature review and synthesis of existing research on tumor microenvironment and immune cell function.
  • Focus on identifying key chemotactic factors and their mechanisms of action in various tumor types.

Main Results:

  • Specific tumor microenvironments are defined by unique chemotactic factor profiles.
  • These factors are crucial for recruiting and activating immune cells within the tumor.
  • The composition and metabolic state of tumor-associated leukocytes are emerging as critical intervention targets.

Conclusions:

  • Targeting chemotactic factors and modulating tumor-associated leukocytes presents a promising avenue for cancer intervention.
  • Further research into these mechanisms can lead to novel therapeutic strategies for managing cancer growth and dissemination.
