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.
Signals Travel Into Cells. Cells communicate by sending and receiving signals. Signals may come from the environment, or they may come from other cells. In order to trigger a response, these signals must be transmitted across the cell membrane.Sometimes the signal itself can cross the membrane.ignals Travel Into Cells.
