Modulation of PKC-mediated phosphorylation affects the odor response of Drosophila OSNs. (A,B) Recordings of neuronal activity before and after Etb stimulation (−5 v/v; 0.5 s, bars) following injection of indicated compounds (Control, injection of receptor lymph solution). Etb stimulation enhances the activity of the A neuron but not of the B neuron. Inhibition of PLC (U73122) and PKC (Gö6976) reduces the Etb response of the A neuron (A) whereas activation of PKC (OAG, PMA) enhances the Etb response (B). (C) Normalized spike frequency (fnorm) of the A neuron upon Etb stimulation (0–0.5 s, at −5 v/v) after injection of receptor lymph solution (Control; n = 11), U73122 (n = 13), or Gö6976 (n = 12). Both treatments reduce the odor response (for P see text). (D) fnorm as described in (C) after injection of ringer solution (Control; n = 11) OAG (n = 8) or PMA (n = 10).
