Summary
Cancer-associated fibroblasts (CAFs) and immune cells in the tumor microenvironment (TME) communicate metabolically. Understanding these interactions is key to developing new cancer therapies targeting tumor growth and immunity.
Area of Science:
- Tumor Microenvironment (TME) Biology
- Cancer Metabolism
- Immunology
Background:
- Cancer-associated fibroblasts (CAFs) and immune cells are critical components of the TME.
- Cellular metabolism regulates TME dynamics, influencing cancer progression and anti-tumor immunity.
- Metabolic interactions between TME cells are complex, involving direct metabolite exchange and indirect signaling.
Purpose of the Study:
- To explore the metabolic interplay between CAFs and immune cells within the TME.
- To review current knowledge on CAF and immune cell metabolic states, interactions, and subpopulations.
- To identify potential metabolic targets within the TME for cancer therapy.
Main Methods:
- Literature review and synthesis of current research on TME cell metabolism.
- Analysis of known metabolic states and interactions of CAFs and immune cells.
- Exploration of CAF-immune cell metabolic crosstalk mechanisms.
Main Results:
- CAFs and immune cells exhibit distinct and plastic metabolic profiles.
- Metabolic interactions between CAFs and immune cells can be direct (metabolite exchange) or indirect (signaling-mediated).
- Subpopulations of CAFs and immune cells possess unique metabolic characteristics influencing TME functions.
Conclusions:
- Metabolic communication between CAFs and immune cells significantly shapes the TME.
- Targeting these metabolic interactions offers promising strategies for cancer treatment.
- Further research into TME metabolic plasticity is crucial for developing effective therapies.

02:17The 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...

5.7K
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

3.7K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

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.

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...
