Expression of transient receptor potential (TRP) channel mRNAs in the mouse olfactory bulb

► TRP channel mRNAs were detected in OB tissue and its neurons using RT-PCR. ► All 28 TRP channel mRNAs except TRPV5 were detected in OB tissue. ► Total 14 TRP channel mRNAs over 6 subfamilies were screened in three cell types. ► Common channel expression was similar between external tufted and mitral cells.
