Detailed Description
Statement
Reference

Mutant larvae show defective locomotion (the degree of direction change per second is significantly reduced compared to wild type) and show a significant reduction in the response to a transient, noxious mechanical stimulus compared to wild type.

The distinct acid-evoked transient inward Na[+] current (I[[t]]) seen in voltage-clamped wild-type class IV multidendritic (md) neurons in primary neuron cultures following acid stimulus and then removal of amiloride blockade is abolished in mutant class IV md neurons, while the sustained acid-evoked inward Na[+] current (I[[s]]) is unaffected.

The intrinsic characteristics and firing frequency of action potentials evoked by supra-threshold depolarizing currents are similar in current-clamped class IV md neurons from both wild-type and ppkESB flies.

Comments

The defects in locomotion and response to a transient, noxious mechanical stimulus seen in ppkESB larvae are rescued by expression of ppkScer\UAS.T:Zzzz\FLAG under the control of Scer\GAL4ppk.1.9.

Expression of ppkScer\UAS.T:Zzzz\FLAG under the control of Scer\GAL4ppk.1.9 rescues the acid-evoked transient inward Na[+] current (I[[t]]) in ppkESB class IV multidendritic neurons in primary neuron culture.
