Integrated System for Purification and Assembly of PCV Cap Nano Vaccine Based on Targeting Peptide Ligand.
Article in International journal of nanomedicine, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThe vaccine design has shifted from attenuated or inactivated whole pathogen vaccines to more pure and defined subunit vaccines. The purification of antigen proteins, especially the precise display of antigen regions, has become a key step affecting the effectiveness of subunit vaccines. MATERIALS AND
methodsThis work presents the application of molecular docking for a peptide ligand designed for PCV2 Cap purification and assembly in one step. Based on the PCV2 Cap protein affinity peptide (L11-DYWWQSWE), the amino terminal of PCV2 Cap was covalently coupled with the polylactic acid-glycolic acid copolymer (PLGA) carboxyl terminal through the EDC/NHS method.
resultsThe PLGA had an average diameter of 106 nm. The average diameter increased to 122 nm after the PCV2 Cap protein conjugation, and the Zeta potential shifted from -13.7 mV to -9.6 mV, indicating that the PCV2 Cap protein stably binds to the PLGA. Compared with the free PCV2 Cap protein group, the neutralizing antibody titer was significantly increased on the 14th day after the PLGA-Cap immunization (P < 0.05). The neutralizing antibody level was extremely significant on the 28th day (P < 0.001). The CCK-8 analysis showed that PLGA-Cap had an obvious cytotoxic effect on RAW264.7 cells at the PLGA nanoparticle concentration up to 200 μg/mL but had no obvious cytotoxic effect on DC2.4 cells. Compared with the Cap protein group, the antigen-presenting cells had a stronger antigen uptake capacity and a higher fluorescence in the PLGA-Cap group. The immune effect showed that the level of the neutralizing antibody produced by this structure is much better than that of purified protein and helps improve the immune system response.
conclusionThis technology provides a potential new perspective for the rapid enrichment of the antigen protein with the affinity peptide ligand.
