A neuron releases a signaling chemical called a neurotransmitter across a synaptic gap to influence another cell. Any major body component or target cell that receives the signal may be another neuron, but it could also be a gland or muscle cell. These signals enable you to move your limbs, experience sensations, maintain heartbeat, as well as receive and process all the information your body receives from other internal body parts and your environment.

The cytokine describes the group of proteins such as interferons and interleukins that regulate cell communication, mainly produced by the immune system in normal and pathological conditions.
<h3>What is a cytokine?</h3>
They are messenger molecules with a glycoprotein structure, whose lifetime is short and generally secreted in cascades.
They are produced by different activated cells, responsible for innate and/or acquired immunity, and regulate the immune and inflammatory response.
Therefore, we can conclude that the cytokine describes the group of proteins that regulate cell communication, mainly produced by the immune system in normal and pathological conditions.
