This chemokine is very important in the human body’s response to cancers. While it sometimes allows cancer to invade more rapidly, it more often helps the human body fight cancer. [6] Some cancers that form tumors, such as breast cancer, produce CCL17 which draws T regulatory cells into the area, enhancing the cancer’s ability to invade. [6]
Chemokines (from Ancient Greek χῠμείᾱ (khumeíā) ' alchemy ' and κῑ́νησῐς (kī́nēsis) ' movement '), or chemotactic cytokines, are a family of small cytokines or signaling proteins secreted by cells that induce directional movement of leukocytes, as well as other cell types, including endothelial and epithelial cells.
Chemokine receptors are cytokine receptors found on the surface of certain cells that interact with a type of cytokine called a chemokine. [ 1 ] [ 2 ] There have been 20 distinct chemokine receptors discovered in humans. [ 3 ]
CXCL1 exists as both monomer and dimer and both forms are able to bind chemokine receptor CXCR2. [11] However, CXCL1 chemokine is able to dimerize only at higher (micromolar) concentrations and its concentrations are only nanomolar or picomolar upon normal conditions, which means that the form of WT CXCL1 is more likely monomeric while dimeric CXCL1 is present only during infection or injury.
CCL2 is a small cytokine that belongs to the CC chemokine family. CCL2 tightly regulates cellular mechanics [ 5 ] and thereby recruits monocytes , memory T cells , and dendritic cells to the sites of inflammation produced by either tissue injury or infection .
Cytokine receptors are receptors that bind to cytokines. [ 1 ] In recent years, the cytokine receptors have come to demand the attention of more investigators than cytokines themselves, partly because of their remarkable characteristics, and partly because a deficiency of cytokine receptors has now been directly linked to certain debilitating ...
CCL1 is involved in inflammatory processes through leukocyte recruitment and could play a crucial role in angiogenesis and other viral and tumoral processes. [10] [11] [12] For example, CCL1 transcription was increased in primary human CD4 + T cells expressing T cell immunoglobulin and protein 3 containing the mucin domain (TIM-3) and was identified as a differentially transcribed gene in CD4 ...
CXC chemokine receptors are integral membrane proteins that specifically bind and respond to cytokines of the CXC chemokine family. They represent one subfamily of chemokine receptors , a large family of G protein-linked receptors that are known as seven transmembrane (7-TM) proteins, since they span the cell membrane seven times.
