  2. Tumor microenvironment - Wikipedia

    en.wikipedia.org/wiki/Tumor_microenvironment

    The concept of the tumor microenvironment (TME) dates back to 1863 when Rudolf Virchow established a connection between inflammation and cancer. However, it was not until 1889 that Stephen Paget's seed and soil theory introduced the important role of TME in cancer metastasis, highlighting the intricate relationship between tumors and their surrounding microenvironment.

  3. Warburg effect (oncology) - Wikipedia

    en.wikipedia.org/wiki/Warburg_effect_(oncology)

    Another model has been described in tumor cells in an obesity model called Warburg effect inversion. Whereas in the reverse model, the stroma of the microenvironment produces energy-rich nutrients, in a context of obesity these nutrients already exist in the bloodstream and in the extracellular fluid (ECF).

  4. Tumor-associated macrophage - Wikipedia

    en.wikipedia.org/wiki/Tumor-associated_macrophage

    The composition of monocyte-derived macrophages and tissue-resident macrophages in the tumor microenvironment depends on the tumor type, stage, size, and location, thus it has been proposed that TAM identity and heterogeneity is the outcome of interactions between tumor-derived, tissue-specific, and developmental signals. [2]

  5. Cancer-associated fibroblast - Wikipedia

    en.wikipedia.org/wiki/Cancer-associated_fibroblast

    A cancer-associated fibroblast (CAF) (also known as tumour-associated fibroblast; carcinogenic-associated fibroblast; activated fibroblast) is a cell type within the tumor microenvironment that promotes tumorigenic features by initiating the remodelling of the extracellular matrix or by secreting cytokines.

  6. Tumor necrosis factor - Wikipedia

    en.wikipedia.org/wiki/Tumor_necrosis_factor

    Tumor necrosis factor (TNF), formerly known as TNF-α, is a chemical messenger produced by the immune system that induces inflammation. [5] TNF is produced primarily by activated macrophages, and induces inflammation by binding to its receptors on other cells. [6]

  7. Cancer stem cell - Wikipedia

    en.wikipedia.org/wiki/Cancer_stem_cell

    The cancer stem cell model, also known as the Hierarchical Model proposes that tumors are hierarchically organized (CSCs lying at the apex [6] (Fig. 3).) Within the cancer population of the tumors there are cancer stem cells (CSC) that are tumorigenic cells and are biologically distinct from other subpopulations [7] They have two defining features: their long-term ability to self-renew and ...

  8. Circulating tumor cell - Wikipedia

    en.wikipedia.org/wiki/Circulating_Tumor_Cell

    A circulating tumor cell (CTC) is a cancer cell from a primary tumor that has shed into the blood of the circulatory system, or the lymph of the lymphatic system. [1] CTCs are carried around the body to other organs where they may leave the circulation and become the seeds for the subsequent growth of secondary tumors.

  9. Cytokine - Wikipedia

    en.wikipedia.org/wiki/Cytokine

    It has been shown that inflammatory cytokines cause an IL-10-dependent inhibition of [24] T-cell expansion and function by up-regulating PD-1 levels on monocytes, which leads to IL-10 production by monocytes after binding of PD-1 by PD-L. [24] Adverse reactions to cytokines are characterized by local inflammation and/or ulceration at the ...
