Chemokine humoral immune response

The activation, maturation, differentiation, and mobilization of immune cells are controlled by cytokines (e.g., interleukins, interferons, and chemokines), which are soluble mediators produced by immune cells and/or by cells outside the immune system (e.g., epithelial cells and cells of the nervous system). Other soluble (humoral) mediators produced by immune cells include antibodies (immunoglobulins) and complement proteins (plasma proteins produced by monocytes and macrophages as well as hepatocytes). Mediators are important in the implementation and regulation of immune responses.
