What are Cytokines? Types & Function - Cleveland Clinic
2023年1月3日 · 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?
Cytokine - Wikipedia
Cytokines (/'saɪ.tə.kaɪn/) [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.
The Role of Cytokines in the Body - Verywell Health
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: Introduction | British Society for Immunology
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.
Cytokines: From Clinical Significance to Quantification
Cytokines are critical mediators that oversee and regulate immune and inflammatory responses via complex networks and serve as biomarkers for many diseases. Quantification of cytokines has significant value in both clinical medicine and biology as ...
