Abstract:
More than 20 years ago, the 'danger theory' was proposed which explains why potent immune responses with no microbial components are elicited against tissue transplants, injuries, tumours and autoimmune diseases. It states that the immune system can distinguish between dangerous and innocuous endogenous signals. In response to trauma or other types of tissue and cell damage, certain molecules that function inside the cell are released or secreted from damaged or dying cells. Such mechanisms initiate an immune response in the absence of infection. These immunostimulatory molecules were named damage-associated molecular patterns (DAMPs). In this article, we will review the available data on the influence of select DAMPs on lung cancer cells and tumour microenvironments. We will also summarize the current information regarding the interactions between lung cancer-associated DAMPs and their toll-like receptors.
Insights
The danger theory explains immune responses to non-infectious triggers like cell damage. This review focuses on damage-associated molecular patterns (DAMPs) and their role in lung cancer.
Area of Science:
- Immunology
- Oncology
- Molecular Biology
Background:
- The 'danger theory' posits that the immune system responds to endogenous danger signals from damaged cells, not just microbes.
- Damage-associated molecular patterns (DAMPs) are released by stressed or dying cells, initiating immune responses without infection.
- These DAMPs play a role in various conditions, including tissue injury, autoimmunity, and cancer.
Purpose of the Study:
- To review the influence of specific damage-associated molecular patterns (DAMPs) on lung cancer cells.
- To examine the impact of DAMPs within the lung tumour microenvironment.
- To summarize the interactions between lung cancer-associated DAMPs and their cognate toll-like receptors.
Main Methods:
- Literature review of existing data on DAMPs in lung cancer.
- Analysis of studies investigating DAMPs' effects on lung cancer cells.
- Summary of research on DAMP-toll-like receptor interactions in the context of lung cancer.
Main Results:
- DAMPs can modulate lung cancer cell behavior and the tumor microenvironment.
- Specific DAMPs interact with toll-like receptors (TLRs) to influence tumor progression.
- Evidence suggests DAMPs can promote or inhibit lung cancer, depending on the context.
Conclusions:
- DAMPs are critical endogenous signals involved in lung cancer pathogenesis.
- Understanding DAMP-TLR interactions offers potential therapeutic targets for lung cancer.
- Further research is needed to fully elucidate the complex roles of DAMPs in lung cancer.
