HTT and infection: Differentiated SHSY5Y cells transiently transfected with either htt‐N63‐18Q or htt‐N63‐148Q were infected with either AAV‐CaM‐peptide + GFP or AAV‐scram‐CaM‐peptide + GFP, or were uninfected (MOI = 50), and 96 h post‐infection levels of cytotoxicity were measured using the LDH assay.
