Expression of various transient receptor potential (TRP) subtypes and calcium (Ca²⁺) influx by their agonists in the mammalian central nervous system (CNS). (A) Expression profile of various TRP channels, NHE1, and NBC, in mammalian CNS cell types. (B) Ca²⁺ influx through activation of TRP subtypes by various agonists or activators in the mammalian CNS. TRP, transient receptor potential; PMCA, plasma membrane Ca²⁺ ATPase; NBC, Na⁺/${\text{HCO}}_3^{-}$ cotransporters; NHE, Na⁺/H⁺ exchangers.
