What do cancer cells secrete?
Tumor cells often produce elevated levels of cell-surface receptors specific for the proteins and polysaccharides composing basal laminae (e.g., collagens, proteoglycans, and glycosaminoglycans) and secrete enzymes that digest these proteins.
What cells can secrete cytokines?
Cytokines are mainly produced by macrophages and lymphocytes, although they can also be produced by polymorphonuclear leukocytes (PMN), endothelial and epithelial cells, adipocytes, and connective tissue. Cytokines are essential to the functions of macrophages.
What do cancer cells release?
As tumors grow and become malignant, however, they gain the ability to break through these boundaries and invade adjoining tissues. Invasive cancer cells often secrete proteases that enable them to degrade the extracellular matrix at a tissue’s boundary.

What cancers release cytokines?
Which Cytokines Are Involved With Cancer?
| Cancer type | Sample | % Elevated |
|---|---|---|
| Various | Serum | – |
| Glioblastoma | CSF | 85% |
| Lymphoma | Serum | 78% |
| Lymphoma | Serum | 100% |
Are cytokines good or bad?
Cytokines play a broad role to help the immune system respond to diseases, and drugs which modulate their effect have led to some amazing therapies. Cytokines may be “good” when stimulating the immune system to fight a foreign pathogen or attack tumors.
What causes the release of cytokines?
During infection, bacterial and viral products, such as bacterial lipopolysaccharide (LPS), cause the release of cytokines from immune cells. These cytokines can reach the brain by several routes. Furthermore, cytokines, such as interleukin-1 (IL-1), are induced in neurons within the brain by systemic injection of LPS.
What does cytokines do to the body?
Cytokines affect the growth of all blood cells and other cells that help the body’s immune and inflammation responses. They also help to boost anti-cancer activity by sending signals that can help make abnormal cells die and normal cells live longer.
What causes cancer to spread fast?
When cancer spreads in the body, it is first and foremost due to changes, or mutations, in the DNA of cells. Because of a mutation or other abnormality in a cancer cell’s genome (the DNA stored in its nucleus), the cell may become separated from its neighbors and invade surrounding tissue.
