Characteristics of sFT-expressing RV vectors <i>in vivo</i>.

<p><b>A</b>: Schematic diagram of transsynaptic tracing with sFT-expressing RV vector. <b>B</b>: Fluorescence photomicrographs of sFT fluorescence in the 1^st-order infected area (CA1) and 2^nd-order infected area (contralateral CA3) 6 dpi of rHEP5.0-GctL-FTFPF into MEC. Scale bar = 50 μm. <b>C</b>: Blue-to-red fluorescence intensity ratio (mean ± standard errors, numbers of analyzed cells: 717 for CA1 and 651 for CA3, *** p < 0.001) of infected CA1 and CA3 neurons. <b>D</b>: Proportions of Red-neurons and Blue-neurons in CA1 and CA3. The number in each pie chart shows the number of analyzed neurons. dCA1, distal CA1; mCA1, medial CA1; pCA1, proximal CA1; dCA3, distal CA3; pCA3, proximal CA3; con-dCA3, contralateral distal CA3; con-pCA3, contralateral proximal CA3.
