Modulation of human TRPV1 receptor activity by extracellular protons and host cell expression system.

The transient receptor potential vanilloid 1 (TRPV1) receptor is a ligand-gated cation channel that can be activated by capsaicin, heat, protons and cytosolic lipids. We compared activation of recombinant human TRPV1 receptors stably expressed in human 293 cells, derived from kidney embryonic cells, and in human 1321N1 cells, derived from brain astrocytes… CONTINUE READING
