Summary
Chronic inflammation fuels immunosuppressive myeloid-derived suppressor cells (MDSCs) in melanoma. Targeting MDSCs may improve cancer immunotherapy by overcoming the tumor microenvironment
Area of Science:
- Oncology
- Immunology
Background:
- Malignant melanoma exhibits rapid progression, metastasis, and resistance to conventional therapies.
- Melanoma's immunogenic potential is hindered by a profoundly immunosuppressive tumor microenvironment.
- This microenvironment is characterized by an accumulation of immunosuppressive myeloid-derived suppressor cells (MDSCs).
Purpose of the Study:
- To discuss the role of chronic inflammation in recruiting and activating MDSCs in melanoma.
- To explore therapeutic strategies targeting MDSCs to enhance melanoma immunotherapy.
Main Methods:
- Review of literature on melanoma, chronic inflammation, MDSCs, and immunotherapy.
- Discussion of mechanisms of MDSC recruitment and activation in the tumor microenvironment.
Main Results:
- Chronic inflammation in the melanoma microenvironment drives MDSC accumulation and activity.
- MDSCs contribute significantly to the immunosuppressive tumor microenvironment, hindering effective immunotherapy.
- Targeting MDSCs presents a potential strategy to overcome immune suppression.
Conclusions:
- Chronic inflammation is a key factor in melanoma-induced immunosuppression via MDSCs.
- Therapeutic targeting of MDSCs holds promise for improving melanoma immunotherapy outcomes.

Tumor Immunotherapy
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
Cytotoxic T Cells-mediated Immune Response
Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...
