- mice Four-week-old female Balb / c mice were nasally infected with 1 ⁇ 10 5 pfu of H1N1 Influenza A / Puerto Rico / 8/34 virus, followed by 25, 100 or 400 units of hzVSF_var13 at 2, 4 or 6 days of infection. Intravenously. At 7 and 9 days after virus infection, mice were sacrificed for H & E staining, lung and body weight, mucosal epithelial cells and cilia, and immunohistochemical staining to infiltrate immune cells.
- influenza titers were reduced by 100 times or more in the group administered with 500 U hzVSF_var13 compared to the control group (FIG. 41).
- the group infected with H1N1 influenza virus developed immune cells and infiltrates in the alveoli
- the group treated with 100 U and 400 U were treated with influenza virus like normal lungs as the lung tissue of the non-infected control group regardless of the timing of administration. Symptoms were cured. Even when 25 U was administered, there was a difference depending on the timing of administration, but it was confirmed that there is a therapeutic effect because it suppresses infiltration of immune cells (FIG. 42).
- the virus-infected group increased the proportion of lungs by weight due to pneumonia-filled pneumonia, whereas the group receiving hzVSF_var13 was proportional to the concentration.
- the group receiving hzVSF_var13 was proportional to the concentration.
- hzVSF and various variants thereof of the present invention not only have excellent antiviral effect against influenza virus, but also inhibit inflammation with an anti-inflammatory effect that inhibits infiltration of immune cells. It suggests that it can be used.
- hzVSF_wt and variants thereof of the present invention exhibit antiviral effects against various viruses
- the effects of hzVSF_wt and representative variants hzVSF_var13 were confirmed in vitro and in vivo .
- In vitro experiments were for antiviral activity and in vivo experiments were for antiviral and anti-inflammatory.
- Encephalomyocarditis virus (EMCV) +++ +++ Mengovirus +++ NT Reovirus + NT Influenza virus + +++ HIV ++ NT HCMV + NT Mouse hepatitis virus (MHV) ++ +++ Hantaan Virus ++ NT HBV ++ NT HCV ++ NT
- hzVSF showed excellent antiviral activity and anti-inflammatory in both in vitro and in vivo for brain myocarditis (EMCV) virus.
- Mengovirus showed excellent antiviral activity in vitro .
- Reovirus has also been shown to be effective in vitro and in vivo .
- HIV has also shown antiviral efficacy in vitro . It also showed antiviral and anti-inflammatory effects against HCMV. It was shown to be effective in vitro against the Hantan virus and antiviral activity against hepatitis B and C viruses in vitro .
- MHV which causes hepatitis in mice with a mechanism similar to human hepatitis, has been shown to exhibit antiviral and anti-inflammatory properties, particularly in vivo .
- Influenza virus showed antiviral and anti-inflammatory effects in vitro and in vivo , and its efficacy was more excellent in vivo .
- Example 19 In the mouse model mVSF Inhibition of inflammatory cytokine secretion by administration
- mice were infected with EMC-D virus and 3 days after mVSF administration, the amount of inflammatory cytokines was measured by ELISA in serum. As shown in Table 16 below, inflammatory cytokines IL-6, TNF- ⁇ , IFN- ⁇ and MCP-1 were increased after viral infection, but administration of mVSF inhibited the expression of these inflammatory cytokines.
- mVSF also has an anti-inflammatory effect of inhibiting inflammation induced by viral infection.

- VSF also has anti-inflammatory effect of inhibiting inflammation induced by viral infection.
- Example 20 In the mouse model hzVSF Inhibition of inflammatory cytokine secretion by administration
- mice infected with 1 ⁇ 10 5 pfu of H1N1 (Influenza A / PR8) influenza virus and the lungs of mice administered 500 units of hzVSF_var13 were extracted one day after infection.
- GLB Greenberger Lysis Buffer
- PE detection reagent 1: 1: 1 1, and then blocked at room temperature Reaction was carried out for 2 hours. After the reaction, the bead was resuspended in the wash buffer, and data was measured by FACS cantoII.
- Example 21 Vimentin Effect of hzVSF after EMC-D Infection on Stable Cell Line
- Non-mentin (wt) or non-mentin (mt) overexpressing cell lines were prepared by transforming non-mentin-expressing MCF-7 cells with non-mentin (wt) or non-mentin (mt) mutated binding sites with hzVSF. Then, MVIT assay was performed using selected cells with similar expression levels.
- hzVSF_var13 was added by diluting 4 times serially from 256 U and incubated for 2 days. Then, the cells were fixed with methanol, stained with 0.5% crystal violet, and air dried.
- a WST assay was further performed to confirm cytotoxicity.
- the cells were treated with tetrazolium salt (WST-1) for an additional 4 hours and incubated at 450 nm wavelength. Absorbance was measured. After the measurement, the supernatant was removed, and the cells were fixed with methanol, followed by fixation staining using 0.5% crystal violet for 20 minutes, and air dried. Stained cells were dissolved in methanol and absorbance was measured at 540 nm.

- VSF receptor (VR) VSF receptor
- each stable MCF-7 cells namely, non-mentin (wt) and non-mentin (mt) were infected with 5 MOI of EMC-D for 9 hours, and then cells were immunostained with hzVSF_var13. After fixing the cells, permeabilization and diluting 1: 250 hzVSF_var13 were reacted with the cells. The secondary antibody was reacted with FITC-goat human IgG and fluorescence microscopy confirmed receptor (VR) expression for hzVSF in cells (500 magnification).
- hzVSF_var13 was not bound to the non-mentin-expressing cells in which the binding sites of mock and hzVSF were mutated as shown in FIG. 55, but it was confirmed that VR was expressed by viral infection in the cells expressing the non-mentin of wt (Fig. 53).
