Sion E, Ab-Rahim S, Muhamad M. Trends on Human Norovirus Virus-like Particles (HuNoV-VLPs) and Strategies for the Construction of Infectious Viral Clones toward In Vitro Replication. Life (Basel) 2023; 13:1447. [PMID: 37511822 PMCID: PMC10381778 DOI: 10.3390/life13071447] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2023] [Revised: 06/07/2023] [Accepted: 06/10/2023] [Indexed: 07/30/2023] Open
Abstract
Most acute gastroenteritis (AGE) outbreaks and sporadic cases in developing countries are attributable to infection by human norovirus (HuNoV), the enteric virus mainly transmitted via fecal-contaminated water. However, it has been challenging to study HuNoV due to the lack of suitable systems to cultivate and replicate the virus, hindering the development of treatments and vaccines. Researchers have been using virus-like particles (VLPs) and infectious viral clones to overcome this challenge as alternatives to fresh virus isolates in various in vitro and ex vivo models. VLPs are multiprotein structures that mimic the wild-type virus but cannot replicate in host cells due to the lack of genetic materials for replication, limiting downstream analysis of the virus life cycle and pathogenesis. The development of in vitro cloning systems has shown promise for HuNoV replication studies. This review discusses the approaches for constructing HuNoV-VLPs and infectious viral clones, the techniques involved, and the challenges faced. It also highlights the relationship between viral genes and their protein products and provides a perspective on technical considerations for producing efficient HuNoV-VLPs and infectious viral clones, which could substitute for native human noroviruses in future studies.

Two viruses from Stylosanthes guianensis may represent a new genus within Potyviridae. Virus Res 2020; 293:198257. [PMID: 33309914 DOI: 10.1016/j.virusres.2020.198257] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2020] [Revised: 11/27/2020] [Accepted: 12/03/2020] [Indexed: 11/21/2022]
Abstract
Forage crops occupy large areas of tropical pastures for cattle feeding in Brazil. The use of stylos (Stylosanthes spp.) in these pastures, which are leguminous shrubs, has increased in the country due to their outstanding nutritional value and for being an efficient and alternative source for nitrogen fixation in the soil. In recent years, virus-like mosaic symptoms on S.guianensis leaves have often been observed in the field, indicating possible virus-like pathogen infections. In an effort to identify the causal agent, virus semi-purification protocol was performed using symptomatic S. guianensis leaves collected at EMBRAPA Beef Cattle Research Center. Total RNA extracted from this semi-purified preparation was submitted to high-throughput sequencing, which revealed complete genome sequences of novel viruses of the family Potyviridae. These viruses, tentatively named stylo mosaic-associated virus 1 (StyMaV-1) and stylo mosaic-associated virus 2 (StyMaV-2), shared 73 % CP aa identity and 77 % polyprotein aa identity with each other and, after that, being closest related to blackberry virus Y, genus Brambyvirus (only 41 % CP aa identity). Based on ICTV genus demarcation criteria, StyMaV-1 and StyMaV-2 represent new species of a new genus within the family Potyviridae. StyMaV-1 and StyMaV-2 are also not efficiently transmitted to other plant species by mechanical inoculation.

Comparative study of chikungunya Virus-Like Particles and Pseudotyped-Particles used for serological detection of specific immunoglobulin M. Virology 2019; 529:195-204.

Abstract
The incidence of chikungunya virus (CHIKV) infection has increased dramatically in recent decades. Effective diagnostic methods must be available to optimize patient management. IgM-capture Enzyme-Linked Immunosorbent Assay (MAC-ELISA) is routinely used for the detection of specific CHIKV IgM. This method requires inactivated CHIKV viral lysate (VL). The use of viral bioparticles such as Virus-Like Particles (VLPs) and Pseudotyped-Particles (PPs) could represent an alternative to VL. Bioparticles performances were established by MAC-ELISA; physico-chemical characterizations were performed by field-flow fractionation (HF5) and confirmed by electron microscopy. Non-purified PPs give a detection signal higher than for VL. Results suggested that the signal difference observed in MAC-ELISA was probably due to the intrinsic antigenic properties of particles. The use of CHIKV bioparticles such as VLPs and PPs represents an attractive alternative to VL. Compared to VL and VLPs, non-purified PPs have proven to be more powerful antigens for specific IgM capture.

Abstract
Noroviruses (NoVs) are one of the most important foodborne viral pathogens worldwide. Oysters are common carriers of NoVs and are responsible for their transmission. NoVs recognize human histo-blood group antigens (HBGAs) as receptors. Recent studies indicate that HBGA-like molecules also exist in oyster tissues and that they may play a key role in the binding of NoVs. However, the mechanism by which different genotypes of NoV accumulate in different oyster tissues is unknown. In this study, the presence and distribution of different types of HBGA-like molecules were evaluated in 240 oysters collected from the Shandong Peninsula of People's Republic of China for 1 year. The HBGA-like molecules were detected at various rates and expressed at different levels in different tissues. Immunohistochemistry confirmed the diversity of HBGA-like molecules in four oyster tissues. Eight types of HBGA-like molecules (types A, B, H1, Lewis x, Lewis y, Lewis a, Lewis b, and precursor) were assessed in different tissues. Of these, the type A HBGA-like molecule was consistently expressed in the gills, digestive tissue, and mantle, while types H1 and Lewis b HBGA-like molecules were expressed in the digestive tissues. The expression of HBGA-like molecules in response to the NoV challenge was investigated. The levels of types A, H1, and Lewis x increased significantly in specific oyster tissues after exposure to genogroup II, genotype 4 (GII.4) or genogroup I, genotype 3 (GI.3) NoV. The real-time reverse transcription PCR assays indicated that GI.3 NoV mainly accumulated in the digestive tissues of oysters, whereas GII.4 NoV accumulated in the gills, mantle, and digestive tissues. These results provide new insights into the mechanism of NoV bioaccumulation in oysters and suggest that NoV accumulation in oysters may be related to the expression of HBGA-like molecules.

Abstract
Human norovirus (HuNoV) is one of the main causes of acute gastroenteritis worldwide and is responsible for at least 20% of all cases. The detailed molecular mechanism of this norovirus remains unknown due to the lack of a suitable in vitro culturing system. An infectious clone of HuNoV would be a useful tool for elucidating the processes of viral infection and the mechanisms of replication. We developed an infectious cDNA clone of HuNoV using the rapid technique of Gibson Assembly. The complete genome of the HuNoV GII.4 Sydney subtype was cloned into a previously modified pcDNA3.1-based plasmid vector downstream from a cytomegaloviral promoter. We monitored the viral infection in vitro by inserting the reporter gene of the green fluorescent protein (GFP) between the NTPase and p22 genes, also by Gibson Assembly, to construct a HuNoV-GFP replicon. Human Caco-2 cells were transfected with the full-length genomic clone and the replicon containing GFP. The gene encoding the VP1/VP2 capsid protein was expressed, which was indirect evidence of the synthesis of subgenomic RNAs and thus the negative strand of the genome. We successfully constructed the infectious clone and its replicon containing GFP for the HuNoV GII.4 Sydney subtype, a valuable tool that will help the study of noroviral infection and replication.
