Sizes of P3N-PIPO and P3 proteins are indicated below the regions that code for them. P3-derived portion is shaded gray; PIPO-derived portion is in black. Position of inserted GFP coding insertion is indicated by dashed lines. Solid circle indicates VPg at 5′ end; (A)n indicates poly(A) tail. (B) Immunodetection of P3N-PIPO and P3 in TuMV-GFP-infected Arabidopsis . Total protein was extracted from the infected leaves at 14 days post inoculation (dpi), separated in either 4–12% NuPAGE Bis-Tris gel (Life Technologies) (for P3-N-PIPO and P3 detections) or in 4–12% Novex Tris-glycine gel (for GFP detection), blotted onto PVDF membrane and probed with anti-PIPO, anti-P3 or anti-GFP antibody and detected by ECL-plus Western reagents. Positions of protein mobility markers in kilodaltons (kDa) are indicated at right. Lanes indicate total protein from plants inoculated with wild-type (WT) TuMV-GFP, or pipo knockout mutants of TuMV-GFP (p41 and p68). These mutants differ from WT TuMV-GFP by single point mutations that introduce stop codons into the pipo ORF: CGA→ UGA and GGA → UGA at bases 3103 and 3130 in mutants p41 and p68, respectively ( pipo -frame codons shown). These mutations do not alter the amino acid sequence of the overlapping P3 region of the polyprotein. Note that putative P3N-PIPO migrates more slowly (∼28 kDa) than its predicted molecular weight (∼25 kDa).

    Characterization of unfiltered exosomes derived from HTLV-infected cells. A , exosome fractions were collected from cell culture supernatants 1, 2, and 5 days post-seeding in exosome-free medium. Equivalent amounts of exosomes isolated from uninfected CEM and HTLV-1-positive C81, MT2, and ED(−) cells were resolved on 4–20% Tris/glycine gels and analyzed by Coomassie Blue staining. B , CEM, C81, MT2, and ED(−)-derived exosomes (10 μg) and corresponding WCE collected 5 days postseeding were analyzed via Western blot using antibodies against HSP70, Alix, CD63, cytochrome c , and β-actin. C , transmission electron microscopy image analysis of CEM-, C81-, and MT2-derived exosomes are shown at ×75,000 magnification.

    Exosomes derived from HTLV-1-infected cells contain viral mRNA transcripts. A , total RNA was isolated from exosomes derived from CEM, C81, MT2, and ED(−) cells and subjected to quantitative RT-PCR in triplicate using primers specific for HTLV-1 Tax, HBZ, 5′-LTR, and Env. Results presented are mean ± S.D. ( error bars ) after normalization to β-globin. B , both cell culture supernatants and exosomes (undiluted and 10 −1 ) derived from CEM, C81, MT2, and ED(−) cells were analyzed for RT activity. C , 293T cells (1 × 10 6 cells) were seeded for 12 h, exposed to CEM- or C81-derived exosomes (10 μg) for 2 h, and then labeled with 35 S label for 4 h. After lysis, cellular extracts were subjected to co-immunoprecipitation using IgG, α-Tax, α-HBZ, or α-Env antibody (3 μg each) overnight at 4 ºC. The next day, Protein A + G was added, and samples were washed with radioimmune precipitation assay buffer and then TNE50 + 0.1% Nonidet P-40. Washed immunoprecipitated complexes were resolved on 4–20% Tris/glycine gels, dried, and imaged using a PhosphorImager. D , raw densitometry counts of images from the PhosphorImager were obtained using ImageJ, and results were normalized to IgG counts before plotting.

    Specific enrichment of exosomes. A , aliquots of 50 ml (5-day-old cultures) of CEM, C81, MT2, and ED(−) cell culture supernatants were clarified by filtration (0.22 μm), whereas 50 ml of each supernatant were left unfiltered. Exosomes (1 μg) isolated from both filtered and unfiltered supernatants were resolved on 4–20% Tris/glycine gels and analyzed by silver staining. B , C81 exosomes from both filtered (9 μg) and unfiltered (7 μg) supernatants and corresponding WCE (10 μg) were evaluated for the incorporation of common exosome markers by Western blot using HSP70, CD63, cytochrome c , and actin antibodies. C , cells were treated with brefeldin A or manumycin A, and the resulting supernatant was collected after 48 h for exosomal preparation ( lanes 1 and 2 ), or exosomes obtained from C81 cells were trypsin-treated or freeze/thawed ( F/T ) and then trypsin-treated ( lanes 3 and 4 ). Lanes 5 and 6 , input exosome controls from C81 or CEM cells, respectively. Resulting exosomes were assayed for the presence of Tax by Western blotting. D , exosomes from MT2 cells were enriched by trapping with nanotrap particles NT080 ( lane 3 ) or NT086 ( lane 4 ) to enrich for virions. Lanes 1 and 2 , are exosomal controls from CEM or MT2 cells, respectively. The trapped exosomes were assayed for the presence of Tax by Western blotting.

    Comparable growth and protein expression levels in an E. coli Δ lgt strain compared with the wild-type strain carrying a conventionally maintained plasmid. (A) Duplicate growth curves of an E. coli BL21 Δ lgt Tn 5 (kan) strain MMS1742 derivative carrying pMT-CTB::p45/lgtVc (pink and blue lines) and wild-type strain E. coli BL21 carrying the equivalent plasmid pML-CTB::p45 maintained by Amp resistance (black line). (B) SDS-PAGE showing expression comparisons of the same strains grown under inducing (lanes 5 to 7) and noninducing (lanes 2 to 4) conditions. Lanes 2 and 5 and lanes 3 and 6 show protein from duplicate cultures of the MMS1742 derivatives grown under inducing and noninducing conditions, respectively, whereas lanes 4 and 7 show the parental BL21 strain carrying plasmid pML-CTB::p45 grown under inducing and noninducing conditions, respectively.

    High-level expression of recombinant proteins in lgt -deleted strains. Shown is an SDS-PAGE gel of protein lysates of the E. coli BL21-derived lgt -deleted strain MMS1742 carrying expression plasmids expressing different recombinant proteins. Lanes 2 and 4 show the respective strains after culturing under noninducing conditions. Cultures were induced by the addition of IPTG. Lane 3 shows the expression of soluble recombinant sj26GST in strain MMS1808 (MMS1742/pMT-sj26GST/lgtVc), and lane 5 shows the expression of recombinant CTB::p45, which is insoluble and produced as inclusion bodies in strain MMS1762 (MMS1742/pMT-CTB::p45/lgtVc).
