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...

Stem Cell Niche01:26

Stem Cell Niche

6.5K
The stem cell niche is the dynamic microenvironment where stem cells reside. Inside these niches, the cells may remain undifferentiated, undergo high self-renewal, or become lineage-specific progenitors. Stem cells coexist with other niche cells, such as stromal cells. They also interact closely with the ECM. Cell-cell and cell-matrix communication occur via adhesion molecules or soluble factors that signal the stem cells and determine their fate. Stromal cells also provide survival signals to...

Area of Science:

  • Oncology
  • Neuroscience
  • Immunology

Background:

  • Breast cancer progression is influenced by the tumor microenvironment.
  • The role of sensory neurons in cancer immunity is not fully understood.

Purpose of the Study:

  • To investigate how sensory neurons interact with breast cancer cells.
  • To determine the impact of this interaction on antitumor immunity.

Main Methods:

  • Analysis of tumor microenvironment in breast cancer models.
  • Investigating sensory neuron activation and signaling pathways.
  • Assessing immune cell infiltration and function within the tumor.

Main Results:

  • Sensory neurons detect signals from breast cancer cells.
  • These neurons promote the formation of a dense stromal barrier.
  • The stromal barrier effectively blocks the infiltration of cytotoxic immune cells.

Conclusions:

  • Sensory neurons contribute to immune evasion in breast cancer.
  • Targeting sensory neuron-stroma interactions may enhance antitumor immunity.
