Summary
Mast cells (MCs) play a dual role in melanoma, potentially fighting tumors or promoting growth within the tumor microenvironment (TME). Understanding MCs
Area of Science:
- Immunology
- Oncology
- Dermatology
Background:
- Mast cells (MCs) are present in various tumors, including melanoma.
- Their role in anti-melanoma immunity is not fully understood.
- The tumor microenvironment (TME) influences MC behavior.
Approach:
- This review examines the complex relationship between mast cells and melanoma.
- It focuses on how the TME affects mast cell activation.
- The potential pro- and anti-tumor functions of mast cells are discussed.
Key Points:
- MCs can release tumoricidal factors and enhance anti-tumor immunity.
- However, in the immunosuppressive TME, MCs may promote angiogenesis and tumor progression.
- The net effect of MCs on melanoma depends on TME context.
Conclusions:
- Mast cells have a context-dependent role in melanoma.
- Further research is needed to elucidate MC functions in the TME.
- Targeting MCs could be a potential therapeutic strategy for melanoma.

4.2K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

02:17The Tumor Microenvironment
6.6K
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...

01:19Pigmentation
2.4K
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

01:19Mesenchymal Stem Cells
4.8K
Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their...

02:38Mitogens and the Cell Cycle
6.5K
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
