Expression of pblScer\UAS.N.T:Ivir\HA1 under the control of Scer\GAL4elav.PLu in embryos leads to mildly increased frequency of defasciculation defects in intersegmental nerve b motor axons compared to controls and very lowly penetrant lateral axon tract disruptions in the central nervous system.

The moderate axon pathfinding defects (defasciculation defects in intersegmental nerve b, ISNb, motor axons very infrequent lateral axon tract disruptions in the central nervous system) characteristic for embryos expressing pblScer\UAS.N.T:Ivir\HA1 under the control of Scer\GAL4elav.PLu are strongly exacerbated by co-expression of Sema1aScer\UAS.cJa and to a lesser extent also by co-expression of Sema1aΔ5.Scer\UAS (increases the frequency of defects in the central nervous system but not in the ISNb) - in addition, both these embryos also display midline crossing defects. Co-expression with either Sema1aScer\UAS.T:Hsap\MYC or Sema1aΔ1-40.Scer\UAS does not enhance the phenotype.

Co-expression of Sema-1aScer\UAS.cJa and pblScer\UAS.N.T:Ivir\HA1 under the control of Scer\GAL4elav.PLu results in ISNb defects in 46.1% of hemisegments. Defects in the lateral-most Fas2-positive longitudinal connectives are seen in 21.6% of hemisegments. An average of 3.6 ectopic midline crossings in the central nervous system are seen per embryo.

Co-expression of Sema-1amICD.Scer\UAS and pblScer\UAS.N.T:Ivir\HA1 under the control of Scer\GAL4elav.PLu results in ISNb guidance defects in more than 40% of hemisegments, while only mild defects in central nervous system patterning are seen.

Co-expression of Sema-1amICD.Scer\UAS.T:Hsap\Fc-IgG and pblScer\UAS.N.T:Ivir\HA1 under the control of Scer\GAL4elav.PLu results in ISNb guidance defects in more than 40% of hemisegments, while only mild defects in central nervous system patterning are seen.

plexAMB09499/+ strongly suppresses the lateral longitudinal central nervous system defects seen in embryos co-expressing Sema-1aScer\UAS.cJa and pblScer\UAS.N.T:Ivir\HA1 under the control of Scer\GAL4elav.PLu, while the ISNb defects are not suppressed.

plexAMB09499/+ significantly suppresses the central nervous system defects seen in embryos co-expressing Sema-1amICD.Scer\UAS.T:Hsap\Fc-IgG and pblScer\UAS.N.T:Ivir\HA1 under the control of Scer\GAL4elav.PLu, while the ISNb defects are not suppressed.

Comments

Expression of pblScer\UAS.N.T:Ivir\HA1 under the control of Scer\GAL4how-24B fails to rescue the motor axon pathfinding defects seen in pbl09645 embryos.

Expression of pblScer\UAS.N.T:Ivir\HA1 under the control of Scer\GAL4sca-537.4 partially but significantly rescues the pathfinding defects in the ISNb and SNa, but not the ISN, motor axon pathways in pbl09645 embryos.
