      Detailed Description
      Statement
      Reference

      Individuals expressing Hsap\TRPV4R269C.UAS under the control of Scer\GAL4elav-C155 or Scer\GAL4CCAP.PU frequently fail to expand their wings after eclosion. Upon Scer\GAL4CCAP.PU-driven expression, N[[CCAP]] neurons show increased spontaneous and evoked firing rate and intrinsic excitability (including increased subthreshold membrane potential variability).

      Adulthood-only expression under the control of Scer\GAL4elav.Switch.PO (induced by RU486) leads to a progressive decline in climbing ability.

      Expressing Hsap\TRPV4R269C.UAS under the control of Scer\GAL4ppk.PU leads to wandering third instar larvae showing a marked loss of C4da neuron axonal projections into the ventral nerve cord and severely reduced dendritic arborizations within the body wall; from there early third instar larval stage there are axonal swellings, fragmentation of distal axonal projections and a reduction of dendritic branching.
