Once released, BNP binds to and activates the atrial natriuretic factor receptor NPRA, and to a lesser extent NPRB, in a fashion similar to atrial natriuretic peptide (ANP) but with 10-fold lower affinity.
The GTP layer for the control plane (GTP-C) tunnels signaling messages between GSNs in the GPRS backbone network.The GTP-C enables several procedures to be performed through the GPRS backbone network, including path management, tunnel management, location management, and mobility management.he GTP layer for the control plane (GTP-C) tunnels signaling messages between GSNs in the GPRS backbone network.
Types of signaling. Autocrine signals bind to receptors on cells that secrete them. Paracrine signals bind to receptors and stimulate nearby cells. Exocrine signaling occurs when cells secrete signaling molecules into the blood.For example, the ovaries in females and the testes in males are stimulated by hormones produced by the brain.ypes of signaling.
