Abstract

Aims: To fully characterise the RGC-5 cell line and determine whether it would be a suitable substitute for primary RGC cell culture. To optimise a CNTF Nogo-P4 inhibitory assay and establish whether (a) CNTF alone is capable of stimulating RGC neurite outgrowth and survival, or (b) an increase in intracellular cAMP is required for CNTF to be effective. To determine whether recombinant AAV2 viral constructs were capable of producing detectable levels of CNTF in HEK-293 transfected conditioned media. To optimise AAV2-eGFP delivery and establish whether AAV2-CNTF-hrGFP and AAV2-CNTF-shRhoA-hrGFP could promote RGC survival and regeneration after optic nerve crush surgery.

Conclusions: RGC-5 cells are not an appropriate substitute for primary retinal cell culture in vitro as they express many of the same markers as oligodendrocyte progenitors. CNTF is capable of stimulating RGC neurite outgrowth without an additional elevation of cAMP. AAV2-mediated GFP expression could be enhanced through the partial digestion of the inner limiting membrane - this seems to be the major obstacle in achieving optimal AAV2 transduction.
