Experimental details: Immunofluorescent analysis of PKC alpha (green) in SH-SY5Y and MCF7 cells. Formalin fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 10 minutes at room temperature. Cells were blocked with 1% Blocker BSA (Product # 37525) for 15 minutes at room temperature. Cells were probed with a PKC alpha monoclonal antibody (Product # MA1-157) at a dilution of 1:100 for at least 1 hour at room temperature, washed with PBS, and incubated with a DyLight 488-conjugated goat anti-mouse IgG secondary antibody (Product # 35502). F-Actin (red) was stained with DyLight-554 Phalloidin (Product # 21834) and nuclei (blue) were stained with Hoechst 33342 dye (Product # 62249). Images were taken on a Thermo Scientific ToxInsight Instrument at 20X magnification.

Experimental details: Immunoprecipitation of PKC alpha was performed using Jurkat whole cell lysate. Antigen-antibody complexes were formed by incubating 400 µg of lysate with 5 µg of a PKC alpha monoclonal antibody (Product # MA1-157) overnight on a rocking platform at 4øC. The immune complexes were captured on 50 µL Protein A/G Agarose (Product # 20421), washed extensively, and eluted with 5X Lane Marker Reducing Sample Buffer (Product # 39000). Jurkat cell lysate (40 µg) was loaded as a positive control (left lane). The sample was resolved on a 4-20% Tris-HCl polyacrylamide gel, transferred to a PVDF membrane, and blocked with 5% BSA/TBS-0.1%Tween for 1 hour. The membrane was probed with a PKC alpha monoclonal antibody (Product # MA1-157) at a dilution of 1:1000 overnight rotating at 4øC, washed in TBST, and probed with a goat anti-mouse IgG-HRP secondary antibody (Product # 31430) at a dilution of 1:20,000 for least 1 hour. Chemiluminescent detection was performed using SuperSignal West Pico (Product # 34080).

Experimental details: Fig. 2. Confocal micrographs of vertical sections from the mouse, hamster, rabbit, and dog retinas. ( A, E, I, M ) DIC images were used to reveal the layers of retina. ( B, F, J, N ) Retinal sections were immunostained for PKC-alpha. ( C, G, K, O ) Retinal sections were immunostained for alpha 1 c L-type Ca 2+ channel. In both labelings, the immunoreactive cells displayed the morphology of rod bipolar cells as their cell bodies in the INL extended long axonal process throughout the IPL. ( D, H, L, P ) Superimposed images of PKC-alpha and alpha 1 c L-type Ca 2+ channel immunolabeling revealed an almost complete of colocalization.

Experimental details: Fig. 3. Confocal micrographs of whole mounts from the mouse, hamster, rabbit, and dog retinas. ( A, D, G, J ) Whole mounts were immunostained for PKC-alpha. ( B, E, H, K ) Whole mounts were immunostained for alpha 1 c L-type Ca 2+ channel. Immunolabeling was visible within the cytoplasm of rod bipolar cells. The immunoreactive cells in the mouse and hamster formed a tight mosaic compared to those in the rabbit and dog. ( C, F, I, L ) Superimposed images of PKC-alpha and alpha 1 c L-type Ca 2+ channel immunostaining revealed that these proteins were colocalized. Bar=20 mum.

Experimental details: Fig. 10 Changes in rod bipolar cells during infection. a anti-PKCalpha staining (green) in an uninfected mouse shows normal distribution and morphology of rod bipolar cells. Numerous dendrites (arrow) reach upward to synapse with photoreceptors in ONL from each cell body (arrowhead). b At 104 dpi rod bipolar cells appear similar to uninfected mouse. c By 118 dpi the number of bipolar cells has dropped to about half vs uninfected and some cell bodies have few if any associated dendrites (arrowhead). d Late in disease, at 163 dpi, rod bipolar cell number is significantly reduced compared to uninfected retina, and few dendrites reach into OPL (arrow). e The number of rod bipolar cells per 100 um of retina over time. Each dot represents counts from one field of view, line is median, ns = not significant, * p < 0.05, ** p < 0.01, *** p < 0.001, **** p 0.0001 statistics by one-way ANOVA with multiple comparisons test.

Experimental details: Fig. 9 PrPSc accumulation at tips of rod bipolar cell dendrites and disappearance of dendrites. Epifluorescent microscopy analysis. a In uninfected retina, PrP (magenta) (blue arrowhead) and PKCalpha-positive rod bipolar cells (green) are seen near each other in the OPL. Many boutons (blue arrow) are present at dendritic tips of rod bipolar cells. b At 82 dpi, OPL appears similar to uninfected. Asterisk marks a rod bipolar cell body in INL. c At 104 dpi, PrP staining appears at dendritic tips. d At 118 dpi, most PKCalpha-positive dendrites display PrP at tips of processes (boutons) (arrow). e By 131 dpi most dendrites and dendritic boutons have disappeared, bipolar cell bodies remain (arrow), and PrPSc is distributed in large aggregates. Confocal analysis. f Maximum intensity projection shows PKCalpha and PrP staining of uninfected retina. Arrows indicate PKCalpha-positive rod bipolar cells with obvious boutons at the ends of dendrites. g A 118 dpi retina shows PrPSc arranged in bead-like deposits on dendrites, often replacing boutons. Magnification of boxes on left and right are shown below in panels h - k . h Confocal image shows association of PrPSc with dendrites and dendritic tips in area of right box from g . i-k Confocal images show merged, PrP and PKC staining of left box area in g . l In a high magnification of confocal image, anti-CtBP2 antibody marks ribbons (arrows) and confirms PrPSc deposits (magenta) on tips of dendrites (green) invaginating, but not touching,
