Cytokines & Cell Signaling
Cytokines are cell signaling molecules that aid cell to cell communication in immune responses and stimulate the movement of cells towards sites of inflammation, infection and trauma.
Cytokine signaling is an important part of the human body regulation. Most cytokines are cell-secreted proteins from glial cells in the nervous system and are necessary for intracellular signaling.... Macrophages and dendritic cells engulf foreign particles and send a cytokine signal to nearby dormant lymphocytes.
