Introduction

Influenza breaks out every year and causes severe infection in the respiratory system.1,2 The novel H1N1 influenza pandemic that erupted in North America caused more than 575,400 deaths in 2009.3 Vaccines and antiviral drugs are the main methods to prevent and control influenza. Because of the variation of influenza virus, application of vaccines is severely circumscribed. Current therapeutic strategies for influenza include the M2 ion channel inhibitors, neuraminidase inhibitors, and broad-spectrum antiviral RNA polymerase inhibitors. Amantadine, oseltamivir, and zanamivir, the main M2 ion channel inhibitor and neuraminidase inhibitors that once had a remarkable effect on influenza virus infection, have been reported increasingly for their resistance.46 Development of new drugs and drug combinations is focused on in medicine. Ribavirin (RBV) is a triazole compound and nucleoside analog. As an RNA polymerase inhibitor, RBV is a well-characterized and broad-spectrum antiviral drug against various RNA and DNA viruses, including influenza A and influenza B viruses.7 It was approved by the American Food and Drug Administration for treatment against influenza virus or respiratory syncytial virus infection through nebulizer inhalation in 1986 and hepatitis C virus infection combined with interferon in 2001.8

Nanomaterials have been studied or applied as carriers of drugs in the biomedical field because of their special physical and chemical properties compared with normal materials, such as the small particle size that contributes to the stable nanostructure and enables easy entrance into cells.9,10 It has been reported that silver nanoparticles loaded with paclitaxel enhance apoptosis of HepG2 cancer cells compared with paclitaxel alone.11 Gold nanoparticles are used to deliver chemotherapeutic drugs in research studies because of their remarkable properties, including high surface-area-to-volume ratio, surface plasmon resonance, and so forth.12 Mesoporous silica nanoparticles loaded with doxorubicin exhibit higher intracellular drug release in cancer cells.13 Compared with these elements, selenium nanoparticles (SeNPs) have their own characteristics against virus infection. First, selenium status may affect the function of cells of both innate and adaptive immunity. It has been reported that selenium deficiency is supposed to be related to virus infection, including coxsackie virus and human immunodeficiency virus.14,15 Selenium supplementation in healthy human adults with marginal selenium status results in both beneficial and detrimental effects on cellular immunity to flu caused by influenza virus.16 Sodium selenite suppresses hepatitis B virus transcription and replication in vitro.17 Furthermore, SeNPs were used to induce robust Th1 cytokine pattern with hepatitis B virus vaccination.18 Besides, SeNPs showed anti-type-1 dengue virus activity by depressing cytopathic effect.19 Our previous studies proved that SeNPs loaded with oseltamivir or amantadine can, respectively, inhibit apoptosis induced by influenza virus infection in vitro.20,21

It has been reported that viruses induce apoptosis through caspase-3 activation.2224 Caspase-3 is the primary executioner of programmed cell death. It is directly or indirectly responsible for the cleavage of many proteins and caspases involved in apoptosis.25 It is activated when cleaved into two protein fragments. Cleaved caspase-3 is responsible for the proteolytic cleavage of many critical proteins. Here, RBV was carried by SeNPs, making a new nanoparticle drug system that enters the cells more effectively. Then, the antiviral activity against H1N1 influenza virus of the nano system was detected via cell viability assay and viral titer test in vitro, followed by lungs injury detection. Finally, the relationship between the antiviral activity and caspase-3 apoptotic pathway was explored in both in vitro and in vivo experiments.

Primers and probe were synthetized by Sangon Biotech (Shanghai, People’s Republic of China). Caspase-3 activity assay kit and tunel detection kit were purchased from Beyotime (Jiangsu, People’s Republic of China). Cleaved caspase-3, cleaved poly-ADP-ribose polymerase (PARP), caspase-8, phosphorylated p53 (p-p53), Bax, phosphorylated p38 (p-p38), phosphorylated Jun-amino-terminal kinase (p-JNK), and β-actin monoclone antibodies were supplied by Cell Signaling Technology (Danvers, MA, USA). Dimethylbenzene, 3% hydrogen peroxide (H2O2), 3,3′-diaminobenzidine (DAB), and mounting medium were bought from GBCBIO Technologies (Guangdong, People’s Republic of China).

Synthesis of SeNPs loaded with RBV ([email protected])

About 0.25 mL of 0.1 M Na2SeO3 solution and 2 mL of 0.5 mM VC solution were dropped into 22.75 mL ultrapure water. After stirring for 30 minutes, RBV was added, followed by a dialysis for 24 hours.26 Concentration of [email protected] was detected using inductively coupled plasma-atomic emission spectrometry. The SeNPS and [email protected] samples were stored at 4°C.

Characterization of [email protected]

Morphology of [email protected] was observed by a transmission electron microscopy (TEM). Elemental composition of [email protected] was detected by an energy-dispersive X-ray spectroscopy (EDX). Size distribution and zeta potential of [email protected] were determined by a zetasizer analyzer.27

Cell culture and virus infection

MDCK cells were cultured in DMEM with 10% FBS, 100 U/mL penicillin, and 50 U/mL streptomycin at 37°C with 5% CO2. MDCK cells were infected with H1N1 influenza virus and 50% tissue culture infective dose (TCID50) was calculated.28 In brief, cells were plated for 24 hours and then adsorbed with H1N1 virus for 2 hours. The supernatant was replaced with DMEM containing 2 μg/mL TPCK-treated trypsin. The TCID50 was calculated using the Reed–Muench method.29 H1N1 virus was used for in vitro study at the titer of 100 TCID50/mL, 1000 TCID50/mL for in vivo experiments.

Cell viability test

Cytotoxicity of [email protected] was detected by MTT assay.30 MDCK cells infected by H1N1 virus were treated with 15.6 μM SeNPs and 40 μg/mL RBV and [email protected] containing 15.6 μM SeNPs and 40 μg/mL RBV, respectively, for 24 hours. MTT solution was added at a final concentration of 0.5 mg/mL after 48 hours. Solution in the wells was sucked away 4 hours later, and 150 μL dimethyl sulfoxide was added. The absorbance values were recorded at 570 nm 20 minutes later.

Viral proliferation

RNA level of H1N1 virus was tested by RT-PCR. RNA was extracted and amplification was performed with a one-step RT-PCR kit. Primers were as follows: H1N1 forward primer 5′ CTCAGCAAATCCTACATTA 3′ and reverse primer 5′ TAGTAGATGGATGGTGAAT 3′. Sequence of the probe was CCATAGCACGAGGACTTCTT,31 GAPDH forward primer 5′ CGCCAAGAAGGTGATCATTTC 3′, and reverse primer 5′ CAGGAGGCGTTCGAGATGAC 3′.

Intracellular localization of [email protected]

MDCK cells cultured in dishes were treated with lyso tracker for 90 minutes. DAPI and coumarin-6 labeled [email protected] were added for various time periods of incubation.32 The images were again analyzed and analyzed by a fluorescence microscope.

Caspase-3 activity

Caspase-3 activity was mensurated using a caspase-3 activity detection kit.33

Western blot

Then, the cells were lysed with radioimmunoprecipitation assay buffer.34 The lysates were separated by sodium dodecyl sulfate-polyacrylamide gel. Bands on polyvinylidene difluoride membranes were immunoblotted with primary antibodies, including cleaved caspase-3, cleaved PARP, caspase-8, p-p53, Bax, p-p38, p-JNK and β-actin monoclone antibodies, and secondary antibodies. Images were visualized on a Tanon gel imaging system.

Animal infection and treatment

Fifteen female BALB/c mice aged 4–6 weeks (Animal Experiment Center of Guangdong Province, People’s Republic of China) were randomly divided into five groups: physiological saline group that without infection and treatment was as control; mock group was as H1N1 virus control; RBV group was treated with RBV post infection; SeNPs group was treated with SeNPs and [email protected] group was treated with SeNPs loaded with RBV. All mice were anesthetized with 10% chloral hydrate at a dose of 3 μL/g through intraperitoneal injection. Then, the control group was treated with 20 μL physiological saline by nasal dripping, while the other four groups were treated with 20 μL H1N1 virus at a 1,000 TCID50/mL titer by nasal dripping as well.35,36 After 24 hours, RBV, SeNPs and [email protected] that contained 20 μg RBV and 50 nmol SeNPs were administered to anesthetized mice, respectively, via intranasal absorption every 24 hours thereafter for a total of three times. Clinical symptoms of the mice were observed, and then the mice were executed by cervical dislocation after anesthesia with chloral hydrate on the 14th day from which treatment was given last. The lungs were extracted, affused with physiological saline, and fixed in paraformaldehyde before hematoxylin and eosin (H&E) staining, tunel test, and immunohistochemistry staining were done. All mice experiments were approved and guided by the ethics committee of Guangzhou Medical University and Experimental Animal Center of Guangzhou Medical University.

H&E staining, tunel test, and immunohistochemistry

The lungs were fixed in 4% paraformaldehyde for 24 hours, dehydrated in a graded ethanol series, and embedded in paraffin. Sections were embedded in wax and cut into 5 μm slices for H&E staining, tunel test, and immunohistochemistry.37 For the tunel test, slices were labeled with tunel reaction mixture and DAPI. Green fluorescence stood for positive. For immunohistochemistry, slices were dewaxed with dimethylbenzene for 15 minutes and rehydrated with alcohol for 40 minutes before antigen retrieval. After quenching with 3% H2O2 and blocking, the slices were incubated with cleaved caspase-3, cleaved PARP, p-p53, p-p38, and p-JNK antibodies, respectively, at 4°C overnight. Followed by incubation with secondary antibodies and coloration with DAB, the slices were dehydrated and treated with mounting medium before observation under a Leica digital microscope.

Statistical analysis

GraphPad Prism 5.0 software (GraphPad Software, Inc., La Jolla, CA, USA) was used for data analysis.38 Two-tailed Student’s t-test and a one-way analysis of variance were used to evaluate the significance of the data. Differences were considered statistically significant at P<0.05 (*) or P<0.01 (**).39

Results and discussion

Preparation and characterization of [email protected]

As shown in the TEM images in Figure 1A, SeNPs and [email protected] appeared monodisperse and spherical. Moreover, the diameter of SeNPs was 200 nm, while that of [email protected] <100 nm. Size distribution in Figure 1C confirmed that the average sizes of [email protected] and SeNPs were 65 nm and 100 nm, respectively. When decorated with RBV on the surface, the surface-free energy of SeNPs decreased and the nanoparticles became more stable. Thus, the diameter of [email protected] is smaller than SeNPs alone. The particle size of [email protected] contributed to the stable nanostructure, which made it propitious to pass through the cytomembrane. Surface elemental composition analysis was carried out by EDX. Figure 1B reveals a strong signal of Se atom (91.5%), C atom (7.2%), O atom (1.1%), and N atom (0.2%). The presence of O atom indicated that RBV had conjugated to the surface of SeNPs. As shown in Figure 1D, the zeta potential of SeNPs alone was −25 mV and decreased to −10 mV after carrying RBV, explaining the higher stability of [email protected]

Cells viability and viral proliferation with [email protected]

MDCK cells were infected with H1N1 virus and were subsequently untreated or treated with RBV, SeNPs, or [email protected] Cytotoxic effect of MDCK cells was detected by MTT assay. As Figure 2A indicated, cell viability without treatment after infection was 48.4%, and cells treated with RBV or SeNPs achieved a viability of 68.5% and 65.2%, respectively. In addition, cells treated with [email protected] achieved a significant viability of 80.6%. These data indicated that the antiviral activity of RBV effectively got strengthened when coated by SeNPs. RNA level of H1N1 was tested. As was displayed in Figure 2B, cells treated with [email protected] after infection got a lowest titer level than RBV or SeNPs alone, suggesting that RBV was more effective when loaded by SeNPs. In Figure 2C, cells infected with H1N1 virus without treatment showed an enlarged intercellular space, cell swelling, and lysis. The cytopathic effect weakened when treated with [email protected] These assays presented that [email protected] effectively resisted proliferation of H1N1 virus.

Intracellular localization of [email protected]

Endocytosis against nanoparticles is significant to the transmission study of drugs loaded with nanosystems. As Figure 3 shows, the green coumarin-6 labeled [email protected] accumulated on MDCK cells membrane and moved to lysosomes labeled by red lyso tracker, presenting yellow or purple of the overlap sites. Approximately 60 minutes later, [email protected] escaped from lysosomes and released into the cytoplasm. Chen et al17 have reported that SeNPs loaded polysaccharide shuttled across the cell membrane in 1 hour accumulated gradually in lysosomes and dispersed in the cytoplasm. This result is coincident with this study.40 The detection suggested that [email protected] targeted lysosomes for subsequent cellular actions.

Restriction on caspase-3 activation in vitro

Apoptosis is induced during H1N1 virus infection.41 MDCK cells were treated with RBV, SeNPs, or [email protected] after H1N1 virus infection. Activity of caspase-3 was detected, and expression of cleaved caspase-3 or cleaved PARP was investigated. As reflected in Figure 4, caspase-3 activity of cells infected by H1N1 virus without treatment was 352% of the control group in which cells were uninfected, while the [email protected] group markedly reduced to 208%, compared with 262% of the RBV-treated group and 304% of the SeNPs group. It suggested that H1N1 virus probably induced apoptosis through caspase-3 and was effectively suppressed by [email protected] In addition, expression of caspase-8 protein was decreased and that of cleaved caspase-3 and cleaved PARP increased after H1N1 infection. When treated with [email protected], changes of the three turned weak. These results suggested that [email protected] inhibited apoptosis by regulating caspase-8, caspase-3, and PARP proteins. Caspase-8 is an apoptosis initiator. Activated caspase-8 cleaves apoptosis executioners, such as caspase-3, caspase-6, and caspase-7.42 Cleaved caspase-3 is responsible for the proteolytic cleavage of many critical proteins, such as the PARP. Cleavage of PARP facilitates cellular disassembly and serves as a marker of apoptosis.43 It could be inferred that [email protected] restrained the caspase-3-mediated apoptosis pathway by inhibiting the activation of caspase-8.

Inhibition of apoptosis signaling pathways

MDCK cells infected with H1N1 virus were treated with RBV, SeNPs, and [email protected] for 24 hours. Proteins related to apoptosis signaling pathways were detected. As was mentioned earlier, [email protected] inhibited caspase-3-mediated mitochondrial apoptosis. Bax plays a key role in the apoptosis during mitochondrial stress. It enhances membrane permeability and helps the activation of caspase pathways, such as caspase-3.44 As shown in Figure 5A, H1N1 virus infection led to an increased expression of Bax protein. After treatment with [email protected], the expression was downregulated. In addition, expression of p-p53 had an identical variation tendency with Bax. P53 is activated after phosphorylation. Activated p53 affects apoptosis by regulating Bcl-2 and Bax gene. As an activator of transcription of Bax, p53 benefits the expression of the protein and promotes the apoptosis process after phosphorylation.45 The results suggested that [email protected] might regulate the expression of Bax through attenuating the expression of p53 protein. Meanwhile, [email protected] restrained the activation of caspase-8. It was shown in Figure 5B that both the regulation of caspase-8 and Bax resisted the activation of caspase-3 and inhibited apoptosis of cells.

JNK and p38 signalings could be activated by virus infection.46 Phosphorylation of JNK or p38 is a sign of apoptosis. These two proteins were investigated in this study. As displayed in Figure 5A, expressions of p-JNK and p-p38 increased in cells infected by H1N1 virus without subsequent treatments, but evidently decreased followed by treatment with [email protected] The result reflected that p38 and JNK signaling pathways took part in the restriction of apoptosis with [email protected]

In vivo antiviral efficiency

To evaluate the efficiency of [email protected] against H1N1 influenza virus in vivo, mice were infected with H1N1 virus and treated with RBV, SeNPs, and [email protected], followed by H&E staining, tunel analyses, and immunohistochemical test of lung tissues after being executed (Figure 6A). Mice infected with H1N1 virus without other treatments tended to reduce physical activity and feeding. Mice treated with [email protected] post infection present a more active and increased appetite. As the H&E staining reveals in Figure 6B, the H1N1-infected group manifested as alveolar collapse and perivascular and peribronchiolar edema, compared with the control group. When treated with RBV or SeNPs, the symptoms lessened. Crucially, it is quite amazing that [email protected] attenuated the histopathological manifestations substantially. The result directly indicated that [email protected] evidently protected the lungs from being injured by H1N1 infection. DNA around nucleosomes was cut when apoptosis occurs. Tunel is used for detecting the DNA fragmentation disrupted during apoptosis. As shown in Figure 6B, [email protected] prevents DNA damage during H1N1 infection. Altogether, the H&E stain and tunel analyses illustrate that [email protected] had a good effect on lung injury in mice suffering from H1N1 virus infection. To further investigate the probable mechanism through which [email protected] cured the mice, immunohistochemical test of the lungs was implemented. As exhibited in Figure 6C, cleaved caspase-3, cleaved PARP, p-p53, p-JNK, and p-p38 proteins were found positive for H1N1 virus infection. Nevertheless, treatment with [email protected] reduced the appearance visibly. This result was coincident with the previous in vitro study in which caspase-3, p53, JNK, and p38 participated in the restriction against the H1N1 virus infection of [email protected]

Notes: Mice infected by H1N1 virus was treated with physiological saline (Mock), RBV, SeNPs, or [email protected] (A). Mice without infection and treated with physiological saline were performed as control. H&E and tunel staining (B), as well as immunohistochemistry (C), was carried out.

Conclusion

Loaded with RBV, a broad-spectrum antiviral agent, SeNPs were prepared through a simple and highly efficient method. SeNPs modified with RBV ([email protected]) rescued cells from apoptosis induced by H1N1 influenza virus infection and reduced the virus titer of the culture supernatant. Besides, lung injury and DNA damage were attenuated by [email protected] treatment in mice. Furthermore, activation of caspase-3 signaling pathway was resisted by both in vitro and in vivo experiments. In conclusion, this study elaborates that SeNPs loaded with RBV restrain apoptosis induced by H1N1 influenza virus infection through the caspase-3 signaling pathway.
