Cytokines are signaling proteins that help control inflammation in your body. They allow your immune system to mount a defense if germs or other substances that can make you sick enter your body. Too many cytokines can lead to excess inflammation and conditions like autoimmune diseases. What are cytokines?

Cytokines (/ ˈsaɪtəkaɪn /) [1] are a broad and loose category of small proteins (~5–25 kDa [2]) important in cell signaling. Due to their size, cytokines cannot cross the lipid bilayer of cells to enter the cytoplasm and therefore typically exert their functions by interacting with specific cytokine receptors on the target cell surface.

2022年6月5日 · Cells release cytokines into your blood circulation or directly into tissues. The cytokines locate the immune cells they're designed to target and bind to the cell's receptors. This interaction triggers or stimulates specific responses by the target cells.

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.

Cytokines are a large, diverse family of small proteins or glycoproteins (usually smaller than 30 kDa). Although initially described for their immunomodulatory capabilities, additional roles separate from the immune system in developmental processes are also documented, such as cell differentiation and directed migration.

2020年11月6日 · Cytokines direct the adaptive immune system to produce pathogen-specific antigens that quickly identify the pathogen so the immune system can destroy it.

2022年5月9日 · Cytokines are a family of small proteins that mediate an organism’s response to injury or infection. Cytokines operate by transmitting signals between cells in an organism. Minute quantities of cytokines are secreted, each by a single cell type, and regulatory functions in other cells by binding with specific receptors.

cytokine, any of a group of small, short-lived proteins that are released by one cell to regulate the function of another cell, thereby serving as intercellular chemical messengers.

2022年12月28日 · Cytokines are a group of proteins, which includes low molecular glycoproteins or regulatory proteins, which play a significant role in cell-to-cell communication. In response to stimuli, cytokines are secreted by WBC and other cells.

2023年7月17日 · Cytokines (literally “cell movement”) are a group of small proteins used in cell–signalling. They are produced by a wide range of cells, including macrophages, lymphocytes, mast cells, endothelial cells and fibroblasts.
