Summary
Cancer stem cells (CSCs) evade immune attack. In melanoma, ABCB5+ malignant melanoma initiating cells (MMICs) show immune privilege, suggesting they resist immunotherapy and drive tumor growth.
Area of Science:
- Oncology
- Immunology
- Cancer Stem Cell Biology
Background:
- Cancer stem cells (CSCs) drive tumor initiation and progression.
- CSCs may evade host antitumor immunity.
- Malignant melanoma initiating cells (MMICs) express ABCB5.
Purpose of the Study:
- To investigate the immune privilege of ABCB5+ MMICs.
- To explore the role of MMICs in melanoma immune evasion.
- To assess implications for melanoma immunotherapy.
Main Methods:
- Identification of MMICs based on ABCB5 expression.
- Analysis of immune privilege in ABCB5+ MMICs.
- Comparison with physiologic stem cell immunomodulation.
Main Results:
- ABCB5+ MMICs exhibit relative immune privilege.
- MMICs may be refractory to current immunotherapies.
- MMICs may contribute to tumor immune evasion.
Conclusions:
- MMICs may be responsible for melanoma immune evasion.
- Immunomodulation by CSCs could drive tumor growth and immunotherapy resistance.
- MMIC-driven tumor escape has implications for melanoma immunotherapy strategies.

02:40Cancer Stem Cells and Tumor Maintenance
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

01:27Tumor 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.
01:18Distinctive Features of Adult Stem Cells vs Cancer Stem Cells
A stem cell is an unspecialized cell that can divide without limit as needed and can, under specific conditions, differentiate into specialized cells.
Adult stem cells
Adult stem cells are tissue-specific; hence, they divide to develop the tissue from which they originate. One type of adult stem cell is the epithelial stem cell, which gives rise to the keratinocytes in the multiple layers of epithelial cells in the epidermis of the skin. Adult bone marrow has three distinct types of stem cells:...

02:17The Tumor Microenvironment
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...
02:53Adaptive Mechanisms in Cancer Cells
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,...
