HBEC-5i was transfected with EPCR siRNA (orange) or a negative control siRNA (blue). Forty-eight hours after transfection, HBEC-5i was stained with 1 μg/mL goat polyclonal antibody to EPCR (orange/blue) or goat IgG-negative control (red), followed by Alexa Fluor 488 donkey anti-goat IgG at a 1:1,500 dilution. Data shown are representative of four similar experiments. ( B – D ) Binding of IEs to HBEC-5i transfected with control siRNA or EPCR siRNA under static conditions. The data shown are the mean and SEM from four independent experiments. The difference in mean values compared with the siRNA control was analyzed by a two-tailed paired t test. * P

Article Title: Primary Human Placental Trophoblasts are Permissive for Zika Virus (ZIKV) Replication

Journal: Scientific Reports

doi: 10.1038/srep41389

Putative ZIKV cell entry receptors are expressed in syncytialized primary human trophoblasts. ( A ) Select viral receptor targets were measured on day 5 post isolation. Cultured primary trophoblasts exhibit AXL, DC-SIGN, TYRO3 and TIM-1 , but not L-SIGN transcription as assessed by RT-PCR detection of human transcript message. Isolated reverse transcribed mRNA was amplified using intron/exon junction spanning primers with a GAPDH as a loading control. For DC SIGN and L- SIGN, primers were designed to capture the multiple transcript variants. Discovered major bands are shown comprising RefSeq transcript variant 1 for DC-SIGN, and transcript variants 1, 8, 9 and 10 (larger band), and variants 7 and 11 (smaller band) for L-SIGN. Isolated buffy coat, A549 cells, isolated primary human hepatocytes and whole human liver were used as controls. ( B ) Immunofluorescence labeling for the expression and cellular localization of the Axl presumptive ZIKV entry receptor. Representative images of day 5 uninfected trophoblasts were imaged following antibody probing with goat polyclonal antibody and Alexa Fluor ® 647 labeled anti-goat secondary antibody for detection (i). Z-stacks of 20X immunofluorescence images were deconvolved and maximum projected. Areas were abstracted (ii-iii) to visualize cellular localization at the cell membrane. Panel iii is indicated by the boxed area.

FLAG-tagged bacterial alkaline phosphatase (BAP-FLAG) was used to assess the presence of antibodies against the FLAG tag. Immune complexes were detected with HRP-conjugated goat anti-mouse, -human or -rabbit IgG polyclonal antibody. Sizes of molecular weight markers are indicated on the right.

Galectin-3 expression in KSHV and mock treated cells at 10 days. ( A ) Dual labeled immunofluorescent staining of KSHV-infected and mock infected DMVEC. DMVEC were mock infected or infected with BCBL-1 virus at a moi 0.01 and cultivated in EBM-2 complete media. Uninfected DMVEC in chamber slides seeded at 2×10 5 cells/well were stained by IFA using a polyclonal goat antibody to human galectin-3 (R D Systems, AF1154) at a 1:100 dilution. Infected cells were dual labeled with a monoclonal antibody to KSHV LANA (LANA/ORF73, Vector Laboratory VP-H913) and a goat polyclonal antibody to galectin-3, both at 1:50 dilution, then labeled with donkey anti-mouse rhodamine tagged secondary antibody together with a rabbit anti-goat FITC tagged antibody as a mixture. Photographs were taken with a NIKON TE 2000S microscope at a total magnification of ×600. Shown in ( A ) are galectin-3 positive cells (green) with cytoplasmic and some nuclear staining. DAPI was used to stain nuclei. In ( A ), LANA-positive cells that were rhodamine stained and have a nuclear punctate pattern; galectin-3 positive cells were stained green with FITC. ( B ) Western blot analysis of galectin-3 protein expression in KSHV-infected DMVEC. Mock and KSHV-infected DMVEC lysates (15 µg) were electrophoresed in 4–20% PAGE gels, transferred to nitrocellulose membranes and then screened for expression of galectin-3 using a goat anti-human galectin-3 antibody (R D Systems) at a 1:2000 dilution. Proteins bands of ∼30 kDa showed much reduced levels of galectin-3 in lysates from KSHV-infected DMVEC, compared to the mock infected controls. Densitometry analysis revealed a 10-fold decrease in the amount of galectin-3 protein in DMVEC lysates from KSHV-infected cells. ( C ) RT-PCR analysis of galectin-3 mRNA expression in KSHV-infected DMVEC. Ten nanograms of cDNA from mock and KSHV-infected DMVEC were amplified by PCR using galectin-3 gene-specific primers in Exon 3. PCR products were electrophoresed in 1.5% agarose, and PCR DNA fragments were sized using a 100-bp ladder. The expected fragment size for galectin-3 is 256 bp. GAPDH was amplified as a loading control with a fragment size of 240 bp.

Co-expression of sortilin, APLP2, or both with PCSK9 has no major effect on LDLR degradation. Huh7 cells were transfected with a total of 3 μg using 1 μg of each vector encoding for either a control protein 7B2 (−), sortilin (+), APLP2 (+), or PCSK9 (+), as indicated. After 48 h, lysates were analyzed by Western blotting for expression of the LDLR, sortilin-Myc, APLP2-V5, intracellular pro- and mature-PCSK9-V5, and β-actin. Media were analyzed for secreted endogenous and overexpressed PCSK9-V5 using a rabbit polyclonal human PCSK9 antibody. Quantification of LDLR expression was normalized against that of β-actin. These data are representative of at least 3 different experiments showing similar results.

Immunostaining:

Article Title: Endothelial protein C receptor is overexpressed in rheumatoid arthritic (RA) synovium and mediates the anti-inflammatory effects of activated protein C in RA monocytes
Article Snippet: .. Tissue sections (4 μm) were de‐paraffinised and processed for immunostaining using goat antihuman EPCR antibody (2 μg/ml, R & D systems). .. Negative control samples were incubated with the same concentration of goat IgG.
