abstract：:The Ca2+ receptor mechanism of the parathyroid cell was studied using La3+ as a probe. La3+ was found to bind to the cell surface without further penetration. Measurements of 45Ca fluxes and the cytoplasmic Ca2+ concentration (Ca2+i) revealed a stimulatory component in the action of La3+ on Ca2+ permeability resulting...
