Me aburre tanta música. Interrumpe demasiado las canciones y son demasiaaaaado largas. Yo no pondría ninguna canción o solo 30 segundos de canción. Por lo demás, muchas gracias por toda la información, me ayuda mucho.

Latest THE PIRBRIGHT INSTITUTE Patents: Attenuated African swine fever virus vaccine Stabilised FMDV capsids Stabilised FMDV Capsids Chicken cells for improved virus production Mutant spike protein extending the tissue tropism of infectious bronchitis virus (IBV) Skip to: Description  ·  Claims  ·  References Cited  · Patent History  ·  Patent History Description FIELD OF THE INVENTION The present invention relates to an attenuated coronavirus comprising a variant replicase gene, which causes the virus to have reduced pathogenicity. The present invention also relates to the use of such a coronavirus in a vaccine to prevent and/or treat a disease. BACKGROUND TO THE INVENTION Avian infectious bronchitis virus (IBV), the aetiological agent of infectious bronchitis (IB), is a highly infectious and contagious pathogen of domestic fowl that replicates primarily in the respiratory tract but also in epithelial cells of the gut, kidney and oviduct. IBV is a member of the Order Nidovirales, Family Coronaviridae, Subfamily Corona virinae and Genus Gammacoronavirus; genetically very similar coronaviruses cause disease in turkeys, guinea fowl and pheasants. Clinical signs of IB include sneezing, tracheal rales, nasal discharge and wheezing. Meat-type birds have reduced weight gain, whilst egg-laying birds lay fewer eggs and produce poor quality eggs. The respiratory infection predisposes chickens to secondary bacterial infections which can be fatal in chicks. The virus can also cause permanent damage to the oviduct, especially in chicks, leading to reduced egg production and quality; and kidney, sometimes leading to kidney disease which can be fatal. IBV has been reported to be responsible for more economic loss to the poultry industry than any other infectious disease. Although live attenuated vaccines and inactivated vaccines are universally used in the control of IBV, the protection gained by use of vaccination can be lost either due to vaccine breakdown or the introduction of a new IBV serotype that is not related to the vaccine used, posing a risk to the poultry industry. Further, there is a need in the industry to develop vaccines which are suitable for use in ovo, in order to improve the efficiency and cost-effectiveness of vaccination programmes. A major challenge associated with in ovo vaccination is that the virus must be capable of replicating in the presence of maternally-derived antibodies against the virus, without being pathogenic to the embryo. Current IBV vaccines are derived following multiple passage in embryonated eggs, this results in viruses with reduced pathogenicity for chickens, so that they can be used as live attenuated vaccines. However such viruses almost always show an increased virulence to embryos and therefore cannot be used for in ova vaccination as they cause reduced hatchability. A 70% reduction in hatchability is seen in some cases. Attenuation following multiple passage in embryonated eggs also suffers from other disadvantages. It is an empirical method, as attenuation of the viruses is random and will differ every time the virus is passaged, so passage of the same virus through a different series of eggs for attenuation purposes will lead to a different set of mutations leading to attenuation. There are also efficacy problems associated with the process: some mutations will affect the replication of the virus and some of the mutations may make the virus too attenuated. Mutations can also occur in the S gene which may also affect immunogenicity so that the desired immune response is affected and the potential vaccine may not protect against the required serotype. In addition there are problems associated with reversion to virulence and stability of vaccines. It is important that new and safer vaccines are developed for the control of IBV. Thus there is a need for IBV vaccines which are not associated with these issues, in particular vaccines which may be used for in ovo vaccination. SUMMARY OF ASPECTS OF THE INVENTION The present inventors have used a reverse genetics approach in order to rationally attenuate IBV. This approach is much more controllable than random attenuation following multiple passages in embryonated eggs because the position of each mutation is known and its effect on the virus, i.e. the reason for attenuation, can be derived. Using their reverse genetics approach, the present inventors have identified various mutations which cause the virus to have reduced levels of pathogenicity. The levels of pathogenicity may be reduced such that when the virus is administered to an embryonated egg, it is capable of replicating without being pathogenic to the embryo. Such viruses may be suitable for in ovo vaccination, which is a significant advantage and has improvement over attenuated IBV vaccines produced following multiple passage in embryonated eggs. Thus in a first aspect, the present invention provides a live, attenuated coronavirus comprising a variant replicase gene encoding polyproteins comprising a mutation in one or more of non-structural protein(s) (nsp)-10, nsp-14, nsp-15 or nsp-16.

The replicase gene may encodes a protein comprising the amino acid mutations Pro to Leu at position 85 of SEQ ID NO: 6; Val to Leu at position 393 of SEQ ID NO:7; Leu to Ile at position 183 of SEQ ID NO:8; and Val to Ile at position 209 of SEQ ID NO: 9. The replicase gene may comprise one or more nucleotide substitutions selected from the list of: C to T at nucleotide position 12137; G to C at nucleotide position 18114; T to A at nucleotide position 19047; and G to A at nucleotide position 20139; compared to the sequence shown as SEQ ID NO: 1.

DETAILED DESCRIPTION The present invention provides a coronavirus comprising a variant replicase gene which, when expressed in the coronavirus, causes the virus to have reduced pathogenicity compared to a corresponding coronavirus which comprises the wild-type replicase gene. Coronavirus Gammacoronavirus is a genus of animal virus belonging to the family Coronaviridae. Coronaviruses are enveloped viruses with a positive-sense single-stranded RNA genome and a helical symmetry. The genomic size of coronaviruses ranges from approximately 27 to 32 kilobases, which is the longest size for any known RNA virus. Coronaviruses primarily infect the upper respiratory or gastrointestinal tract of mammals and birds. Five to six different currently known strains of coronaviruses infect humans. The most publicized human coronavirus, SARS-CoV which causes severe acute respiratory syndrome (SARS), has a unique pathogenesis because it causes both upper and lower respiratory tract infections and can also cause gastroenteritis. Middle East respiratory syndrome coronavirus (MERS-CoV) also causes a lower respiratory tract infection in humans. Coronaviruses are believed to cause a significant percentage of all common colds in human adults. Coronaviruses also cause a range of diseases in livestock animals and domesticated pets, some of which can be serious and are a threat to the farming industry. Economically significant coronaviruses of livestock animals include infectious bronchitis virus (IBV) which mainly causes respiratory disease in chickens and seriously affects the poultry industry worldwide; porcine coronavirus (transmissible gastroenteritis, TGE) and bovine coronavirus, which both result in diarrhoea in young animals. Feline coronavirus has two forms, feline enteric coronavirus is a pathogen of minor clinical significance, but spontaneous mutation of this virus can result in feline infectious peritonitis (FIP), a disease associated with high mortality. There are also two types of canine coronavirus (CCoV), one that causes mild gastrointestinal disease and one that has been found to cause respiratory disease. Mouse hepatitis virus (MHV) is a coronavirus that causes an epidemic murine illness with high mortality, especially among colonies of laboratory mice. Coronaviruses are divided into four groups, as shown below: Alpha Canine coronavirus (CCoV) Feline coronavirus (FeCoV) Human coronavirus 229E (HCoV-229E) Porcine epidemic diarrhoea virus (PEDV) Transmissible gastroenteritis virus (TGEV) Human Coronavirus NL63 (NL or New Haven) Beta Bovine coronavirus (BCoV) Canine respiratory coronavirus (CRCoV)—Common in SE Asia and Micronesia Human coronavirus OC43 (HCoV-OC43) Mouse hepatitis virus (MHV) Porcine haemagglutinating encephalomyelitis virus (HEV) Rat coronavirus (Roy). Rat Coronavirus is quite prevalent in Eastern Australia where, as of March/April 2008, it has been found among native and feral rodent colonies. (No common name as of yet) (HCoV-HKU1) ?Severe acute respiratory syndrome coronavirus (SARS-CoV) Middle East respiratory syndrome coronavirus (MERS-CoV) Gamma Infectious bronchitis virus (IBV) Turkey coronavirus (Bluecomb disease virus) Pheasant coronavirus Guinea fowl coronavirus Delta Bulbul coronavirus (BuCoV) Thrush coronavirus (ThCoV) Munia coronavirus (MuCoV) Porcine coronavirus (PorCov) HKU15 The variant replicase gene of the coronavirus of the present invention may be derived from an alphacoronavirus such as TGEV; a betacoronavirus such as MHV; or a gammacoronavirus such as IBV. As used herein the term “derived from” means that the replicase gene comprises substantially the same nucleotide sequence as the wild-type replicase gene of the relevant coronavirus. For example, the variant replicase gene of the present invention may have up to 80%, 85%, 90%, 95%, 98% or 99% identity with the wild type replicase sequence. The variant coronavirus replicase gene encodes a protein comprising a mutation in one or more of non-structural protein (nsp)-10, nsp-14, nsp-15 or nsp-16 when compared to the wild-type sequence of the non-structural protein. IBV Avian infectious bronchitis (IB) is an acute and highly contagious respiratory disease of chickens which causes significant economic losses. The disease is characterized by respiratory signs including gasping, coughing, sneezing, tracheal rales, and nasal discharge. In young chickens, severe respiratory distress may occur. In layers, respiratory distress, nephritis, decrease in egg production, and loss of internal egg quality and egg shell quality are common. In broilers, coughing and rattling are common clinical signs, rapidly spreading in all the birds of the premises. Morbidity is 100% in non-vaccinated flocks. Mortality varies depending on age, virus strain, and secondary infections but may be up to 60% in non-vaccinated flocks. The first IBV serotype to be identified was Massachusetts, but in the United States several serotypes, including Arkansas and Delaware, are currently circulating, in addition to the originally identified Massachusetts type. The IBV strain Beaudette was derived following at least 150 passages in chick embryos. IBV Beaudette is no longer pathogenic for hatched chickens but rapidly kills embryos. H120 is a commercial live attenuated IBV Massachusetts serotype vaccine strain, attenuated by approximately 120 passages in embryonated chicken eggs. H52 is another Massachusetts vaccine, and represents an earlier and slightly more pathogenic passage virus (passage 52) during the development of H120. Vaccines based on H120 are commonly used. IB QX is a virulent field isolate of IBV. It is sometimes known as “Chinese QX” as it was originally isolated following outbreaks of disease in the Qingdao region in China in the mid 1990s. Since that time the virus has crept towards Europe. From 2004, severe egg production issues have been identified with a very similar virus in parts of Western Europe, predominantly in the Netherlands, but also reported from Germany, France, Belgium, Denmark and in the UK. The virus isolated from the Dutch cases was identified by the Dutch Research Institute at Deventer as a new strain that they called D388. The Chinese connection came from further tests which showed that the virus was 99% similar to the Chinese QX viruses. A live attenuated QX-like IBV vaccine strain has now been developed. IBV is an enveloped virus that replicates in the cell cytoplasm and contains an non-segmented, single-stranded, positive sense RNA genome. IBV has a 27.6 kb RNA genome and like all coronaviruses contains the four structural proteins; spike glycoprotein (S), small membrane protein (E), integral membrane protein (M) and nucleocapsid protein (N) which interacts with the genomic RNA. The genome is organised in the following manner: 5?UTR—polymerase (replicase) gene—structural protein genes (S-E-M-N)—UTR 3?; where the UTR are untranslated regions (each ˜500 nucleotides in IBV). The lipid envelope contains three membrane proteins: S, M and E. The IBV S protein is a type I glycoprotein which oligomerizes in the endoplasmic reticulum and is assembled into homotrimer inserted in the virion membrane via the transmembrane domain and is associated through non-covalent interactions with the M protein. Following incorporation into coronavirus particles, the S protein is responsible for binding to the target cell receptor and fusion of the viral and cellular membranes. The S glycoprotein consists of four domains: a signal sequence that is cleaved during synthesis; the ectodomain, which is present on the outside of the virion particle; the transmembrane region responsible for anchoring the S protein into the lipid bilayer of the virion particle; and the cytoplasmic tail. All coronaviruses also encode a set of accessory protein genes of unknown function that are not required for replication in vitro, but may play a role in pathogenesis. IBV encodes two accessory genes, genes 3 and 5, which both express two accessory proteins 3a, 3b and 5a, 5b, respectively. The variant replicase gene of the coronavirus of the present invention may be derived from an IBV. For example the IBV may be IBV Beaudette, H120, H52, IB QX, D388 or M41. The IBV may be IBV M41. M41 is a prototypic Massachusetts serotype that was isolated in the USA in 1941. It is an isolate used in many labs throughout the world as a pathogenic lab stain and can be obtained from ATCC (VR-21™). Attenuated variants are also used by several vaccine producers as IBV vaccines against Massachusetts serotypes causing problems in the field. The present inventors chose to use this strain as they had worked for many years on this virus, and because the sequence of the complete virus genome is available. The M41 isolate, M41-CK, used by the present inventors was adapted to grow in primary chick kidney (CK) cells and was therefore deemed amenable for recovery as an infectious virus from a cDNA of the complete genome. It is representative of a pathogenic IBV and therefore can be analysed for mutations that cause either loss or reduction in pathogenicity.

Replicase In addition to the structural and accessory genes, two-thirds of a coronavirus genome comprises the replicase gene (at the 5? end of the genome), which is expressed as two polyproteins, pp1a and pp1ab, in which pp1ab is an extension product of pp1a as a result of a ?1 ribosomal shift mechanism. The two polyproteins are cleaved by two types of virus-encoded proteinases usually resulting in 16 non-structural proteins (Nsp1-16); IBV lacks Nsp1 thereby encoding Nsp2-16. Thus Gene 1 in IBV encodes 15 (16 in other coronaviruses) non-structural proteins (nsp2-16), which are associated with RNA replication and transcription. The term ‘replicase protein’ is used herein to refer to the pp1a and pp1ab polyproteins or individual nsp subunits. The term ‘replicase gene’ is used herein to refer to a nucleic acid sequence which encodes for replicase proteins. A summary of the functions of coronavirus nsp proteins is provided in Table 1.

Nsp10 has RNA-binding activity and appears to be involved in homo and/or heterotypic interactions within other nsps from the pp1a/pp1ab region. It adopts an ?/? fold comprised of five ?-helices, one 310-helix and three ?-strands. Two zinc-binding sites have been identified that are formed by conserved cysteine residues and one histidine residue (Cys-74/Cys-77/His-83/Cys-90; Cys-117/Cys-120/Cys-128/Cys-130). The protein has been confirmed to bind single-stranded and double-stranded RNA and DNA without obvious specificity. Nsp-10 can be cross-linked with nsp-9, suggesting the existing of a complex network of protein-protein interactions involving nsp-7, -8, -9 and -10. In addition, nsp-10 is known to interact with nsp-14 and nsp-16. Nsp-14 comprises a 3?-to-5? exoribonuclease (ExoN) active domain in the amino-terminal region. SARS-CoV ExoN has been demonstrated to have metal ion-dependent 3?-to-5? exoribonuclease activity that acts on both single-stranded and double-stranded RNA, but not on DNA. Nsp-14 has been shown to have proof-reading activity. This nsp has also been shown to have N7-methyltransferase (MT) activity in the carboxyl-terminal region. Nsp-15 associated NendoU (nidoviral endoribonuclease, specific for U) RNase activity has been reported for a number of coronaviruses, including SARS-CoV, MHV and IBV. The activities were consistently reported to be significantly enhanced by Mn2+ ions and there was little activity in the presence of Mg2+ and Ca2+. NendoU cleaves at the 3? side of uridylate residues in both single-stranded and double-stranded RNA. The biologically relevant substrate(s) of coronavirus NendoUs remains to be identified. Nsp-16 has been predicted to mediate ribose-2?-O-methyltransferase (2?-O-MTase) activity and reverse-genetics experiments have shown that the 2?-O-MTase domain is essential for viral RNA synthesis in HCoV-229E and SARS-CoV. The enzyme may be involved in the production of the cap 1 structures of coronavirus RNAs and it may also cooperate with NendoU and ExoN in other RNA processing pathways. 2?-O-MTase might also methylate specific RNAs to protect them from NendoU-mediated cleavage. The genomic and protein sequences for nsp-10, -14, -15 and -16 are provided as SEQ ID NO: 2-5 and 6-9, respectively.

Reduced Pathogenicity The live, attenuated coronavirus of the present invention comprises a variant replicase gene which causes the virus to have reduced pathogenicity compared to a coronavirus expressing the corresponding wild-type gene. The term “attenuated” as used herein, refers to a virus that exhibits said reduced pathogenicity and may be classified as non-virulent. A live, attenuated virus is a weakened replicating virus still capable of stimulating an immune response and producing immunity but not causing the actual illness. The term “pathogenicity” is used herein according to its normal meaning to refer to the potential of the virus to cause disease in a subject. Typically the pathogenicity of a coronavirus is determined by assaying disease associated symptoms, for example sneezing, snicking and reduction in tracheal ciliary activity. The term “reduced pathogenicity” is used to describe that the level of pathogenicity of a coronavirus is decreased, lessened or diminished compared to a corresponding, wild-type coronavirus. In one embodiment, the coronavirus of the present invention has a reduced pathogenicity compared to the parental M41-CK virus from which it was derived or a control coronavirus. The control coronavirus may be a coronavirus with a known pathogenicity, for example a coronavirus expressing the wild-type replicase protein. The pathogenicity of a coronavirus may be assessed utilising methods well-known in the art. Typically, pathogenicity is assessed by assaying clinical symptoms in a subject challenged with the virus, for example a chicken. As an illustration, the chicken may be challenged at 8-24 days old by nasal or ocular inoculation. Clinical symptoms, associated with IBV infection, may be assessed 3-10 days post-infection. Clinical symptoms commonly assessed to determine the pathogenicity of a coronavirus, for example an IBV, include gasping, coughing, sneezing, snicking, depression, ruffled feathers and loss of tracheal ciliary activity. The variant replicase of the present invention, when expressed in a coronavirus, may cause a reduced level of clinical symptoms compared to a coronavirus expressing a wild-type replicase. For example a coronavirus expressing the variant replicase may cause a number of snicks per bird per minute which is less than 90%, less than 80%, less than 70%, less than 60%, less than 50%, less than 40%, less than 30%, less than 20% or less than 10% of the number of snicks caused by a virus expressing the wild type replicase. A coronavirus expressing a variant replicase according to the present invention may cause wheezing in less than 70%, less than 60%, less than 50%, less than 40%, less than 30%, less than 20% or less than 10% of the number of birds in a flock infected with the a virus expressing the wild type replicase. A coronavirus expressing a variant replicase according to the present invention may result in tracheal ciliary activity which is at least 60%, at least 70%, at least 80%, at least 90% or at least 95% of the level of tracheal ciliary activity in uninfected birds. A coronavirus expressing a variant replicase according to the present invention may cause clinical symptoms, as defined in Table 2, at a lower level than a coronavirus expressing the wild type replicase. TABLE 2 IBV severity limits based on clinical signs: The variant replicase of the present invention, when expressed in a coronavirus, may cause the virus to replicate at non-pathogenic levels in ovo. While developing vaccines to be administered in ovo to chicken embryos, attention must be paid to two points: the effect of maternal antibodies on the vaccines and the effect of the vaccines on the embryo. Maternal antibodies are known to interfere with active immunization. For example, vaccines with mild strains do not induce protective antibody levels when administered to broiler chickens with maternal antibodies as these strains are neutralized by the maternal antibody pool. Thus a viral particle must be sufficiently efficient at replicating and propagating to ensure that it is not neutralized by the maternally-derived antibodies against the virus. Maternally-derived antibodies are a finite pool of effective antibodies, which decrease as the chicken ages, and neutralization of the virus in this manner does not equate to the establishment of long-term immunity for the embryo/chick. In order to develop long-term immunity against the virus, the embryo and hatched chicken must develop an appropriate protective immune response which is distinct to the effect of the maternally-derived antibodies. To be useful for in ovo vaccination, the virus must also not replicate and propagate at a level which causes it to be pathogenic to the embryo. Reduced pathogenicity in terms of the embryo may mean that the coronavirus causes less
