[PMID: 38283623 PMCID: PMC10811427 DOI: 10.1016/j.jvacx.2024.100440] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2023] [Revised: 12/11/2023] [Accepted: 01/13/2024] [Indexed: 01/30/2024] Open
Abstract
The global poultry industry plays a pivotal role in providing eggs and meat for human consumption. However, outbreaks of viral disease, especially Newcastle virus disease (NDV), within poultry farms have detrimental effects on various zootechnical parameters, such as body weight gain, feed intake, feed conversion ratio, as well as the quality of egg and meat production. Cases of vaccine failure have been reported in regions where highly pathogenic strains of NDV are prevalent. To tackle this challenge, virus-like particles (VLPs) have emerged as a potential solution. VLPs closely resemble natural viruses, offering biocompatibility and immune-stimulating properties that make them highly promising for therapeutic applications against NDV. Hence, this review emphasizes the significance of NDV and the need for effective treatments. The manuscript will contain several key aspects, starting with an exploration of the structure and properties of NDV. Subsequently, the paper will delve into the characteristics and benefits of VLPs compared to conventional drug delivery systems. A comprehensive analysis of VLPs as potential vaccine candidates targeting NDV will be presented, along with a discussion on strategies for loading cargo into these NDV-targeting VLPs. The review will also examine various expression systems utilized in the production of NDV-targeting VLPs. Additionally, the manuscript will address future prospects and challenges in the field, concluding with recommendations for further research.

Abstract
As an important structural protein in virion morphogenesis, the matrix (M) protein of Newcastle disease virus (NDV) is demonstrated to be a nuclear-cytoplasmic trafficking protein and plays essential roles in viral assembly and budding. In recent years, increasing lines of evidence have indicated that the M protein has obvious influence on the pathotypes of NDV, and the interaction of M protein with cellular proteins is also closely associated with the replication and pathogenicity of NDV. Although substantial progress has been made in the past 40 years towards understanding the structure and function of NDV M protein, the available information is scattered. Therefore, this review article summarizes and updates the research progress on the structural feature, virulence and pathotype correlation, and nucleocytoplasmic transport mechanism of NDV M protein, as well as the functions of M protein and cellular protein interactions in M's intracellular localization, viral RNA synthesis and transcription, viral protein synthesis, viral immune evasion, and viral budding and release, which will provide an in-depth understanding of the biological functions of M protein in the replication and pathogenesis of NDV, and also contribute to the development of effective antiviral strategies aiming at blocking the early or late steps of NDV lifecycles.

Abstract
The matrix (M) protein of Newcastle disease virus (NDV) contains large numbers of unevenly distributed basic residues, but the precise function of most basic residues in the M protein remains enigmatic. We previously demonstrated that the C-terminus (aa 264-313) of M protein interacted with the extra-terminal (ET) domain of chicken bromodomain-containing protein 2 (chBRD2), which promoted NDV replication by downregulating chBRD2 expression and facilitating viral RNA synthesis and transcription. However, the key amino acid sites determining M's interaction with chBRD2/ET and their roles in the replication and pathogenicity of NDV are not known. In this study, three basic residues-R283, R286, and K288-in the NDV M protein were verified to be responsible for its interaction with chBRD2/ET. In addition, mutation of these basic residues (R283A/R286A/K288A) in the M protein changed its electrostatic pattern and abrogated the decreased expression of endogenic chBRD2. Moreover, a recombinant virus harboring these mutations resulted in a pathotype change of NDV and attenuated viral replication and pathogenicity in chickens due to the decreased viral RNA synthesis and transcription. Our findings therefore provide a better understanding of the crucial biological functions of M's basic residues and also aid in understanding the poorly understood pathogenesis of NDV.

Abstract
The matrix (M) protein of Newcastle disease virus (NDV) is a highly conserved hydrophobic viral protein. In some paramyxoviruses (measles virus and Sendai virus), the paired glycine (G) near the C terminus of the M protein may form a turn that mediates the specific interaction with the cell membrane. Similar amino acids (glycine-proline [GP], at position 275-276) exist in the M protein of NDV. However, the role of these residues in the replication and pathogenicity of NDV is unknown. In this study, recombinant NDV with the sequence GP/AA or LGP/GGL in the M protein was generated to investigate the role of this conserved sequence. Budding experiments on the mutant viruses revealed that the GP/AA mutation reduced virus budding and virus replication in DF-1 cells; biological characterization revealed attenuated virulence and pathogenicity in chickens, indicating that the GP sequence plays a critical role in the life cycle of the virus.

Abstract
The present study was aimed at investigating the therapeutic efficacy of vitamin E on oxidative injury in brain and liver of Newcastle disease virus (NDV) challenged chickens. We have analyzed the xanthine oxidase (XOD) activity; uric acid (UA) levels and superoxide radical generation by using electron spin resonance spectroscopy. Further, protein oxidation, nitration and apoptosis were evaluated in the brain and liver of the control, NDV-infected and NDV+Vit. E treated groups. A significant elevation was observed in XOD activity and UA levels in brain (p<0.001) and liver (p<0.05) of NDV infected birds when compared to controls. Further, significant increase in the production of superoxides, enhanced intracellular protein carbonyls and nitrates were observed in the brain and liver of NDV-infected birds over healthy subjects. Apoptosis studies also suggested that a larger number of TUNEL positive cells were observed in brain and a moderately in liver of NDV-infected chickens. However, all these perturbations were significantly ameliorated in NDV+Vit. E treated chickens as compared to NDV-infected birds. Taken together, our results suggested that NDV-induced neuronal and hepatic damage at least in part mediates oxidative stress and on the other hand, supplementation of vitamin E mitigates NDV-induced oxidative damage thereby protects brain and liver of chickens. These findings could provide new insights into the understanding of NDV pathogenesis and therapeutic effects of dietary antioxidants.

Abstract
The Newcastle disease virus (NDV) matrix (M) protein is a highly basic and nucleocytoplasmic shuttling viral protein. Previous study has demonstrated that the N-terminal 100 aa of NDV M protein are somewhat acidic overall, but the remainder of the polypeptide is strongly basic. In this study, we investigated the role of the N-terminal basic residues in the subcellular localization of M protein and in the replication and pathogenicity of NDV. We found that mutation of the basic residue arginine (R) to alanine (A) at position 42 disrupted M's nuclear localization. Moreover, a recombinant virus with R42A mutation in the M protein reduced viral replication in DF-1 cells and attenuated the virulence and pathogenicity of the virus in chickens. This is the first report to show that a basic residue mutation in the NDV M protein abrogates its nuclear localization and attenuates viral replication and pathogenicity.

Abstract
Newcastle disease (ND) is one of the highly pathogenic viral diseases of avian species. ND is economically significant because of the huge mortality and morbidity associated with it. The disease is endemic in many third world countries where agriculture serves as the primary source of national income. Newcastle disease virus (NDV) belongs to the family Paramyxoviridae and is well characterized member among the avian paramyxovirus serotypes. In recent years, NDV has lured the virologists not only because of its pathogenic potential, but also for its oncolytic activity and its use as a vaccine vector for both humans and animals. The NDV based recombinant vaccine offers a pertinent choice for the construction of live attenuated vaccine due to its modular nature of transcription, minimum recombination frequency, and lack of DNA phase during replication. Our current understanding about the NDV biology is expanding rapidly because of the availability of modern molecular biology tools and high-throughput complete genome sequencing.

Coordinate deletion of N-glycans from the heptad repeats of the fusion F protein of Newcastle disease virus yields a hyperfusogenic virus with increased replication, virulence, and immunogenicity.

Abstract
The role of N-linked glycosylation of the Newcastle disease virus (NDV) fusion (F) protein in viral replication and pathogenesis was examined by eliminating potential acceptor sites using a reverse genetics system for the moderately pathogenic strain Beaudette C (BC). The NDV-BC F protein contains six potential acceptor sites for N-linked glycosylation at residues 85, 191, 366, 447, 471, and 541 (sites Ng1 to Ng6, respectively). The sites at Ng2 and Ng5 are present in heptad repeat (HR) domains HR1 and HR2, respectively, and thus might affect fusion. Each N-glycosylation site was eliminated individually by replacing asparagine (N) with glutamine (Q), and a double mutant (Ng2 + 5) involving the two HR domains was also made. Each mutant was successfully recovered by reverse genetics except for the one involving Ng6, which is present in the cytoplasmic domain. All of the F proteins expressed by the recovered mutant viruses were efficiently cleaved and transported to the infected-cell surface. None of the individual mutations affected viral fusogenicity, but the double mutation at Ng2 and Ng5 in HR1 and HR2 increased fusogenicity >12-fold. The single mutations at sites Ng1, Ng2, and Ng5 resulted in modestly reduced multicycle growth in vitro. These three single mutations were also the most attenuating in eggs and 1-day-old chicks and were associated with decreased replication and spread in 2-week-old chickens. In contrast, the combination of the mutations at Ng2 and Ng5 yielded a virus that, compared to the BC parent, replicated >100-fold more efficiently in vitro, was more virulent in eggs and chicks, replicated more efficiently in chickens with enhanced tropism for the brain and gut, and elicited stronger humoral cell responses. These results illustrate the effects of N-glycosylation of the F protein on NDV pathobiology and suggest that the N-glycans in HR1 and HR2 coordinately downregulate viral fusion and virulence.

Abstract
Naturally occurring Newcastle disease virus (NDV) strains vary greatly in virulence, ranging from no apparent infection to severe disease causing 100% mortality in chickens. The viral determinants of NDV virulence are not completely understood. Cleavage of the fusion protein is required for the initiation of infection, and it acts as a determinant of virulence. The attachment protein HN was found to play a minor role in virulence. In this study, we have evaluated the role of the internal proteins (N, P, and L) in NDV virulence by using a chimeric reverse-genetics approach. The N, P, and L genes were exchanged individually between an avirulent NDV strain, LaSota, and an intermediate virulent NDV strain, Beaudette C (BC), and the N and P genes were also exchanged together. The recovered chimeric viruses were evaluated for their pathogenicity in the natural host, chickens. Our results showed that the pathogenicities of N and P chimeric viruses were similar to those of their respective parental viruses, indicating that the N and P genes probably play minor roles in virulence. However, replacement of the L gene of BC with that of LaSota significantly increased the pathogenicity of the L-chimeric virus, suggesting that the L gene probably contributes to the virulence of NDV. The L-chimeric BC virus was found to replicate at a 100-fold-higher level than its parental virus in chicken brain, suggesting that the increase in pathogenicity may be due to the increased replication level of the chimeric virus. Our findings offer new insights into the pathogenesis of NDV infection.

Abstract
Molecular changes of cell culture-adapted Newcastle disease virus (NDV) were studied by adapting a velogenic NDV isolated from commercial layer chicken-to-chicken embryo fibroblast (CEF) cells. The isolate was passaged 50 times in CEF cells. At every 10th passage the virus was characterized conventionally by mean death time analysis, intracerebral pathogenicity index, and virus titration. As the passage level increased, a gradual reduction in the virulence of the virus was observed. Molecular characterization of the virus included cloning and sequencing of a portion of the fusion gene (1349 bp) encompassing the fusion protein cleavage site (FPCS), which was previously amplified by reverse transcription-polymerase chain reaction. Sequence analysis revealed a total of 134 nucleotide substitutions, which resulted in the change of 41 amino acids between the parent and the 50th passage virus. Pathogenicity studies conducted in 20-wk-old seronegative chickens revealed gross and histopathologic changes in the chickens injected with the parent virus and absence of the lesions in chickens injected with the adapted virus. The 50th passage cell culture virus was back-passaged five times in susceptible chickens and was subjected to virulence attribute analysis and sequence analysis of the FPCS region, with minor differences between them.

Abstract
The matrix protein gene was cloned and sequenced for several recent isolates of avian paramyxovirus type 1 (APMV-1). Specifically, isolates from pigeons and doves, members of the Columbidae family were examined. APMV-1 is the causative agent of Newcastle disease and the virus is associated with disease among a diverse number of avian species. Newcastle disease virus (NDV) isolates from pigeons have also been classified as pigeon paramyxovirus type 1 (PPMV-1). Matrix protein gene sequences for PPMV-1 isolates clustered together as a group relative to isolates from other species phylogenetically. However, there were also isolates from pigeons or doves that grouped with APMV-1 isolates from other species. This indicates that PPMV-1 may be circulating among Columbidae members as a distinct lineage, but that these avian species may also harbor other NDV strains as well. Of particular interest was a dove isolate from Europe that had an aberrant fusion protein cleavage site and was an outlying member phylogenetically between the two major groups of APMV-1 isolates.

Abstract
Twelve Newcastle disease virus (NDV) strains were isolated from chickens involved in outbreaks of Newcastle disease (ND) in western China (Shaanxi, Gansu, Xinjiang, Qinghai and Guangxi provinces) between 1979 and 1999. All strains were determined to be velogenic by plaque formation, the mean death time (MDT) of embryonated eggs, and the intracerebral pathogenicity index (ICPI). For preparation of virus RNA, the acid guanidinium-thiocyanate method was used. A 908bp fragment of nucleotide was amplified by RT-PCR starting from the N terminal of the F gene and the PCR segments were cloned into the PGEM-T vector and sequenced. The similarities of the nucleotide sequences (1-519bp) and predicted amino acid sequences of the F gene (1-125) were analyzed by comparing the 12 NDV isolates with the NDV vaccine strains Lasota, B1, H1 and V4, with classical NDV strains and recent epizootic strains. Phylogenetic analysis demonstrated that all strains were of two novel genotypes; the NDV strains that caused the outbreak of ND in western China during 1998-1999 was of the genotype VIIa, whereas the strains from the Qinghai province (1979-1985) were of genotype VIII, which has been found predominately in southern Africa.

Abstract
Nucleotide sequence was determined for the phosphoprotein (P) gene from 23 Newcastle disease virus (NDV) isolates representing all defined pathotypes with different chronological and geographic origins. Sequence variation, with synonymous substitutions dominating, occurred throughout the P gene. An exception was a conserved central region containing the transcriptional editing site. Four G nucleotide additions were detected in NDV P gene mRNA potentially creating alternative open reading frames. However, only one in-frame stop codon exists with a single G addition among all isolates that would allow for a potential V protein. A second potential stop codon does not exist in the P gene consensus sequence among all isolates with more than one G nucleotide addition at the editing site. This precludes a possible W protein in these isolates. A second potential alternative in-frame start site exists among all isolates that could encode a predicted X protein for NDV. Comparison of the P gene editing sites among the Paramyxovirinae and predicted P gene usage demonstrates that NDV more closely resembles the respiroviruses and morbilliviruses. Phylogenetic analysis of P gene sequences among NDV isolates demonstrates there are two clades of these viruses. One group includes viruses isolated in the US prior to 1970, while a second cluster includes virulent viruses circulating worldwide.

Abstract
Matrix (M) gene sequences for recent field isolates and older reference Newcastle disease viruses (NDV) were examined to determine phylogenetic relationships and population trends among these viruses. Overall, the M gene has a majority of synonymous nucleotide sequence substitutions occurring among NDV isolates. However, several predicted amino acid changes in the M protein of specific NDV isolates have occurred that correlate to phylogenetic relationships. Nucleotide substitutions in these codons have a greater number of nonsynonymous base changes. The NDV isolates arising since the 1970s belong to a population of viruses that expanded worldwide at an exponential rate. These viruses may have their origins in free-living birds, are present worldwide, and continue to circulate causing disease in poultry. A specific NDV lineage composed of virulent isolates obtained in the US prior to 1970 appears to no longer exists among free-living birds or commercial poultry. However, "vaccine-like" viruses are common in the US and continue to circulate among commercial poultry. Based on M protein amino acid sequences, NDV separates as a clade most closely related to morbilliviruses and not with their current designated category, the rubulaviruses among the Paramyxoviridae. Consequently, avian paramyxoviruses should have their own taxonomic subfamily among the Paramyxovirinae.

Abstract
A region constituting 88% of the matrix gene of Newcastle disease virus vaccine strains LaSota and B-1 was amplified by reverse transcription-polymerase chain reaction. Amplified products of LaSota and B-1 strains derived from vaccine serials of different companies were digested with restriction enzymes MboI and HinfI. Strain characteristic cleavage site maps were obtained that allowed for a reliable and rapid differentiation between strains LaSota and B-1.

Abstract
Degenerate oligonucleotide primers were synthesized to amplify nucleotide sequences from portions of the fusion protein and matrix protein genes of Newcastle disease virus (NDV) genomic RNA that could be used diagnostically. These primers were used in a single-tube reverse transcription PCR of NDV genomic RNA coupled to direct nucleotide sequencing of the amplified product to characterize more than 30 NDV isolates. In agreement with previous reports, differences in the fusion protein cleavage sequence that correlated genotypically with virulence among various NDV pathotypes were detected. By using sequences generated from the matrix protein gene coding for the nuclear localization signal, lentogenic viruses were again grouped phylogenetically separate from other pathotypes. These techniques were applied to compare neurotropic velogenic viruses isolated from an outbreak of Newcastle disease in cormorants and turkeys. Cormorant NDV isolates and an NDV isolate from an infected turkey flock in North Dakota had the fusion protein cleavage sequence 109SRGRRQKRFVG119. The R-for-G substitution at position 110 may be unique for the cormorant-type isolates. Although the amino acid sequences from the fusion protein cleavage site were identical, nucleotide sequence data correlate the outbreak in turkeys to a cormorant virus isolate from Minnesota and not to a cormorant virus isolate from Michigan. On the basis of sequence information, the cormorant isolates are virulent viruses related to isolates of psittacine origin, possibly genotypically distinct from other velogenic NDV isolates. These techniques can be used reliably for Newcastle disease epidemiology and for prediction of pathotypes of NDV isolates without traditional live-bird inoculations.

Abstract
Nucleotide sequence analysis was completed for isolates of Newcastle disease virus (NDV; avian paramyxovirus 1) from 1992 outbreaks in cormorants and turkeys. These isolates were of the neurotropic velogenic type. The cormorant and turkey NDV isolates had the fusion protein cleavage sequence 109SRGRRQKR/FVG119, as opposed to the consensus sequence 109SGGRRQKR/FIG119 of most known velogenic NDV isolates. The R for G substitution at position 110 may be unique for the cormorant and turkey isolates. For comparative purposes, nucleotide sequencing and analysis of the conserved matrix protein gene coding region were completed for isolates representing all pathotypes. Phylogenetic relationships demonstrated that there are two major groups of NDV isolates. One group includes viruses found in North America and worldwide, such as B1, LaSota, Texas/GB, and Beaudette/C. The second group contains isolates, such as ulster/2C, Australia/Victoria, and Herts/33, considered exotic to North America. Within this second group are viruses of psittacine origin. The viruses from 1992 outbreaks of Newcastle disease in North America, and an isolate thought to have caused the major outbreak in southern California during the 1970s, are most closely related to an NDV isolate of psittacine origin.

Abstract
The strong cation-exchanger, PolySulfoethyl Aspartamide, has been assessed as a medium for isolation of carboxyl-terminal and blocked amino-terminal peptides from tryptic digests of small quantities of viral proteins. Peptides with a single positive charge, the blocked amino-terminal peptides of ovalbumin and the Newcastle disease virus (NDV) matrix protein and carboxyl-terminal peptides of ovalbumin and the NDV nucleocapsid protein, eluted in early ion-exchange fractions and were readily isolated in homogeneous form by subsequent reversed-phase HPLC. Some early ion-exchange fractions also contained singly charged peptides derived by "chymotryptic-like" cleavage, whilst other peptides eluted in these fractions due to their highly acidic character. Terminal sequences with additional basic residues were isolated from later eluting ion-exchange fractions. Peptides with this property included the blocked amino-terminus of the NDV nucleocapsid protein and a portion of the carboxyl-terminus of the NDV matrix protein. Hitherto undescribed polymorphism in the amino-terminal region of ovalbumin was revealed in this study. Truncated peptides from the carboxyl-terminus of the NDV matrix protein were also detected. The presence of these peptides could be a reflection of carboxyl-terminal processing of the matrix protein. The strategy described herein should be of general utility for selective microisolation of carboxyl-terminal peptides and blocked amino-terminal peptides from tryptic digests of proteins.

Abstract
The nucleotide sequence of the M gene of human parainfluenza virus type 1 (hPIV1) was determined from genomic RNA and cDNA copies of the entire gene. The M gene contained 1173 nucleotides. It had one large open reading frame capable of encoding a protein of 348 amino acids (M(r) = 38,404). The predicted amino acid sequence of the hPIV1 M protein is highly basic (+20 at neutral pH). A pGEM-1 expression vector containing the M gene was used for cell-free transcription and translation. The resultant protein was confirmed to be M by electrophoretic mobility and immunoprecipitation. Among other paramyxoviridae the hPIV1 M amino acid sequence was most closely related to the Sendai virus M sequence (87% identity). The pattern of M gene relatedness observed from the alignment of 16 paramyxoviridae M protein amino acid sequences was not predicted by the viruses' taxonomic classification.

Abstract
The nucleotide sequences of the NP and M genes of human parainfluenza type 1 virus (HPIV-1) were determined. The NP gene was 1677 nucleotides long excluding polyadenylic acid. The NP gene contained a single large open reading frame (ORF), which encoded a polypeptide of 524 amino acids with a calculated molecular weight of 57,736. The M gene 1173 nucleotides long excluding the poly(A) tract and the sequence also contained a single large ORF which encoded a polypeptide of 348 amino acid with a molecular weight of 38,445, which was inconsistent with 28 kDa previously determined by SDS-PAGE. We aligned the deduced HPIV-1 NP and M protein sequences with 12 and 13 other paramyxoviruses, respectively, suggesting that a common tertiary structure was found in the NPs or Ms of HPIV-1, Sendai virus (SV), HPIV-3 and BPIV-3 and that other common structure was also maintained in these proteins of HPIV-2, SV 41 and 5, MuV, HPIV-4. Phylogenetic trees were constructed for the NP and M proteins of all the paramyxoviruses of which nucleotide sequences had been previously reported. Paramyxoviruses could be subdivided into two groups, i.e., PIV-1 group and PIV-2 group; the former group is composed of HPIV-1, SV, HPIV-3 and BPIV-3, and the latter group consists of HPIV-2, SV 41, SV 5, MuV, HPIV-4 A and HPIV-4 B.

Abstract
The complete nucleotide sequence of the L protein gene of sonchus yellow net virus (SYNV), a plant rhabdovirus, was determined by dideoxynucleotide sequencing of cloned cDNAs derived from the negative-strand genomic RNA. The L protein gene is composed of 6401 nucleotides (nt) located between positions 7158 and 13558 relative to the 3' end of the genomic RNA. Sequence analysis suggests that the complementary mRNA contains a 44 nt untranslated 5' leader sequence preceding an open reading frame of 6348 nucleotides that is capable of encoding a polypeptide of 2116 amino acids with a deduced molecular weight of 241,569 Da. The L protein is positively charged, has a high proportion of the amino acids Leu and Ile, and contains putative polymerase and RNA binding domains. Extended alignment of the SYNV L protein amino acid sequence with those of other nonsegmented negative-strand RNA virus polymerases reveals conservation of sequences within 12 blocks that appear sequentially along the protein. A cluster dendrogram derived from the L protein alignments indicates that SYNV is more closely related to animal rhabdoviruses than to the paramyxoviruses and that the animal rhabdoviruses have diverged less from each other than from SYNV.

Abstract
Several biochemical properties and the sequence of the fusion glycoprotein (F) have indicated that turkey rhinotracheitis virus (TRTV) is a pneumovirus, subfamily Pneumovirinae of the Paramyxoviridae family. As TRTV was known to generate polycistronic mRNAs, cDNA was generated from TRTV strain UK/3BV/85-infected Vero cell mRNAs using an oligonucleotide primer corresponding to a region of the F gene. Sequencing of four cDNAs revealed that the gene adjacent to the beginning (3' end) of the F gene was that for the matrix (M) protein, i.e., that TRTV had the partial gene order 3'-M-F-5'. This was unexpected as human respiratory syncytial (RS) virus, the type species of the genus Pneumovirus, has the partial gene order 3'-M-SH-G-F-5', where SH and G are the small hydrophobic protein and attachment glycoprotein, respectively. Instead TRTV resembled the Morbillivirus and Paramyxovirus genera of the Paramyxoviridae (subfamily Paramyxovirinae) which have the partial gene order 3'-M-F-5'. Two further oligonucleotides, one corresponding to a sequence near the end of the M gene and the other (oligo B) to a sequence near the beginning of the F gene, with their 5' ends spaced 300 nucleotides apart on the basis of the cDNA sequence, were used in a polymerase chain reaction (PCR) using genomic RNA as template. Only a PCR product of 0.3 kb was obtained. The same sized product was also obtained using these oligonucleotides and genomic RNA from three other TRTV strains (SA/91/78, UK/8544/85, and SA/2381/88) which had been grown in chicken tracheal organ cultures. In addition PCR was performed using genomic RNA from TRTV-3BV and SA/2381/88 with oligo B and another oligonucleotide near the 5' end of the gene upstream from M, spaced 1141 nucleotides apart on the basis of the sequence data. Only a 1.14-kb PCR product was obtained. Larger products would have been expected if another gene had been situated between M and F. The absence of such larger products, plus the demonstration that infected cells contained M-F dicistronic mRNAs, supported the conclusion that in the TRTV genome the M gene is adjacent to the F gene in the order 3'-M-F-5'. The 5' termini of the M and F mRNAs were confirmed by mRNA mapping. The TRTV M gene encoded a protein of 254 amino acids, very similar to that of RS virus (256 residues; 37% amino acid identity) but very different from that of the morbilliviruses and paramyxoviruses (approximately 350 residues).(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
Nonsegmented negative strand RNA viruses comprise major human and animal pathogens in nature. This class of viruses is ubiquitous and infects vertebrates, invertebrates, and plants. Our laboratory has been working on the gene expression of two prototype nonsegmented negative strand RNA viruses, vesicular stomatitis virus (a rhabdovirus) and human parainfluenza virus 3 (a paramyxovirus). An RNA-dependent RNA polymerase (L and P protein) is packaged within the virion which faithfully copies the genome RNA in vitro and in vivo; this enzyme complex, in association with the nucleocapsid protein (N), is also involved in the replication process. In this review, we have presented up-to-date information of the structure and function of the RNA polymerases of these two viruses, the mechanisms of transcription and replication, and the role of host proteins in the life-cycle of the viruses. These detailed studies have led us to a better understanding of the roles of viral and cellular proteins in the viral gene expression.

Abstract
The sequence of the M gene of human parainfluenza virus type 2 (PIV-2) has been determined. The sequence contained a large open reading frame with 1131 nucleotides encoding a protein with a calculated molecular weight of 42,312. Comparison of M protein sequence indicated that PIV-2 was more closely related to mumps virus and Newcastle disease virus than to other parainfluenza viruses, Sendai virus (SV), and parainfluenza virus type 3 (PIV-3), indicating a possible subdividing of the Paramyxovirus into two groups. This grouping is consistent with that obtained from analysis of the HN gene. Measles virus and canine distemper virus definitely belong to the subgroup composed of SV and PIV-3. No homology region was found in all the paramyxoviruses compared. However, a tertiary structure may be conserved in each subgroup of paramyxovirus. The M protein of PIV-2 was expressed in bacteria, and the product was recognized by a monoclonal antibody specific for the PIV-2 M protein. The bacterial-expressed protein, however, was heterogeneous and smaller in size.

Abstract
The gene encoding the M1 protein of sonchus yellow net virus (SYNV), a plant rhabdovirus, has been sequenced and identified by Western blot analysis of SYNV proteins using antibodies directed against a fusion protein derived from a portion of the sequenced gene. The M1 gene is positioned between nucleotides 4039 and 5109 relative to the 3' end of the viral RNA and is the fourth gene from the 3' end of the genome. The 1071-nucleotide (nt) M1 gene lies between a putative nonstructural gene of unknown function and the gene encoding the glycoprotein and is bordered on either side by the same GG intergenic dinucleotide that separates other genes in the SYNV genome. The M1 mRNA (scRNA 6) consists of a 71-nt untranslated region at the 5' terminus followed by an 858-nt open reading frame (ORF) capable of encoding a protein with a calculated molecular weight of 31,779. The amino acid sequence deduced from this ORF is not highly homologous to those of other rhabdovirus matrix proteins, but has some localized regions of similarity. The UGA codon that terminates the M1 ORF is followed by a 3' untranslated region of 142 nt. The viral RNA (minus-sense) sequence corresponding to the extreme 3' end of the mRNA contains a 9-nt tract (3'-AUUGUUUUU-5') that is identical to the sequences at the termini of other SYNV genes.

Abstract
The complete nucleotide sequence of the membrane (M) protein gene of the paramyxovirus simian virus 5 (SV5) was determined from cDNA clones of viral mRNAs. The M gene boundaries were determined by (i) primer extension sequencing on M mRNA; (ii) nuclease S1 analysis; and (iii) primer extension sequencing on viral genomic RNA. The M gene mRNA consisted of 1371 templated nucleotides. It contains a single large open reading frame that can encode a protein of 377 amino acids with a predicted Mr = 42,253. The authenticity of the predicted M protein coding sequence was confirmed by synthesis of the M protein from mRNA synthesized from cDNA. The predicted M amino acid sequence indicated it is an overall hydrophobic protein carrying a net positive charge. Alignment of the SV5 protein amino acid sequence with the M protein sequences of other paramyxoviruses indicated that these viruses fall into the following two groups: (1) SV5, mumps virus, and Newcastle disease virus; or (2) Sendai, parainfluenza virus type 3, measles virus, and canine distemper virus, with mumps virus M sequence being the most closely related to SV5.

Abstract
Sequence analysis and comparison of the fusion glycoprotein genes of 11 Newcastle disease virus (NDV) isolates indicated a high degree of functional and structural constraint exerted on the change of the glycoprotein. However, synonymous nucleotide substitutions occurred frequently throughout the coding region. Facilitated by an analysis of synonymous difference (Ks) in pairwise strain comparison, we defined the branching orders of the strains and identified three distinct evolutionary lineages correlating with the virulence as expressed by mean death time (MDT) for chick embryo. The typically virulent strains with MDT of about 50 hr were associated with one lineage, while the typically nonvirulent strains with MDT of infinity were of another lineage. The third lineage consisted of both virulent and avirulent strains whose MDTs lay on a continuum from 50 to 120 hr. Synonymous substitutions were found to occur with almost the same rates in the adjacent hemagglutinin-neuraminidase and membrane protein genes as in the fusion protein gene, and the branching orders based upon the Ks for these genes were essentially identical to those derived from the fusion protein gene. Therefore, no gene exchange by recombination seems to have occurred to generate the strains of distinct lineages. Rather, the different strains appear to have evolved through various degrees of accumulation of point mutations. Besides these evolutionary features, the present study strongly supports the importance of the previously identified signals for gene expression and for the proteolytic activation of the gene product.

Abstract
The complete nucleotide sequence of the mumps virus membrane protein or matrix protein (M) has been determined by sequencing cDNA clones and confirmed by partially sequencing the M mRNA and the genome. The mRNA is 1248 nucleotides long excluding the poly(A) and encodes a protein of 375 amino acids. The molecular weight (38,670), deduced from the amino acid sequence, is in agreement with the molecular weight of the viral M protein estimated by polyacrylamide gel electrophoresis (39-40 kDa). The mumps virus M protein shows 23-27% homology with M proteins of Newcastle disease virus (NDV), measles virus, canine distemper virus (CDV), parainfluenza virus type 3, and Sendai virus, respectively. A comparison of the M protein sequences of the above six paramyxoviruses did not reveal any conserved area of homology common among all paramyxovirus M proteins.

Abstract
cDNA clones representing the M, F and a putative SH gene of the SBL strain of mumps virus have been prepared and their nucleotide sequence determined. The M gene of mumps virus appears to contain 1253 nucleotides and codes for a protein of 375 amino acid residues (Mr 41,589). The protein is hydrophobic and the deduced amino acid sequence shows homologies with those of other paramyxoviruses. The F gene of the SBL strain was compared to that of the RW strain [Waxham et al. (1987) Virology 159, 381-388]. The F gene is 1727 nucleotides long and codes for a protein of 538 amino acids (Mr 58,789). There are substantial variations between the F gene sequences of various mumps virus strains. The F gene is followed by a small (315 nt) transcription unit which contains an open reading frame of 57 amino acids encoding a very hydrophobic protein (Mr 6712). This may be similar to the SH gene of SV5, although there appears to be no sequence homology between the SV5 SH protein and the putative SH protein of mumps virus. A physical and transcription map of mumps virus indicates the gene order to be 3'-N-P-M-F-SH-HN, similar to that of other paramyxoviruses and SV5 in particular.

Abstract
An immunoaffinity method was designed for purification of a soluble form of the matrix (M) protein of Newcastle disease virus. The resulting M protein sedimented in a sucrose gradient as a small complex. This purified M protein associated with liposomes containing a net neutral, negative, or positive charge. The liposomes were composed of phosphatidylcholine, cholesterol, and a third lipid which provided the charge. The M protein-liposome associations were not prevented by high salt conditions. These observations are consistent with a nonelectrostatic association between the M protein and liposomes. Monoclonal antibodies to three separate epitopes of the M protein were all able to bind M protein complexed with liposomes, suggesting that the three M protein epitopes are not directly involved in the interaction between the M protein and liposomes. The M protein was also able to associate with liposomes lacking cholesterol implying that cholesterol does not play a substantial role in the M protein-liposome interaction.

Abstract
We have now completed the rabies genome structure by the cloning and the sequencing of the entire L gene and the 5' untranscribed region. The L gene encodes a single open reading frame 2142 amino acids in length (244,206 Da) that corresponds to the viral RNA-dependent RNA polymerase. In contrast with other isofunctional proteins, the rabies polymerase exhibits a high degree of homology with the vesicular stomatitis virus polymerase, and a lesser degree, although significant, with those of Sendai virus and Newcastle disease virus, which suggests a differential evolution of the different cistrons. We have observed several strongly conserved stretches which may designate the independent functional domains of this multifunctional protein. In addition to the conservation of related transcription signals (N. Tordo et al. (1986) Proc. Natl. Acad. Sci. USA 83, 3914-3918.), this highlights the striking selective pressure on elements involved in transcription and replication mechanisms, and provides further evidence for a common ancestry of Rhabdoviridae and Paramyxoviridae families. The terminal complementarity observed in the rabies genome suggests the conservation of important genomic signals.

Abstract
Paramyxoviruses are a fascinating group of viruses with diverse hosts and disease manifestations. They are valuable systems for studying viral pathogenesis, molecular mechanisms of negative strand viral replication, and glycoprotein structure and function. In the past few years this group of viruses has received increased attention and as a result there is a wealth of new information. For example, most of the genes of many paramyxoviruses have been cloned and sequenced. The recent availability of sequence information from a number of paramyxoviruses now allows the direct comparison of the amino acid sequence and determinants of secondary structure of analogous genes across the family of viruses. Such comparisons are revealing for two reasons. First, results provide clues to the evolution of these viruses. Second, and more importantly, comparisons of analogous genes may point to sequences and structural determinants that are central to the function of the individual proteins. Below is a comparison of five of the paramyxovirus genes with a discussion of the implications of common structural determinants for function, intracellular processing, and evolutionary origin. The focus is on the paramyxovirus membrane proteins, although other proteins are discussed briefly.

Abstract
The nucleotide sequence of the L gene of the Beaudette C strain of Newcastle disease virus (NDV) has been determined. The L gene is 6704 nucleotides long and encodes a protein of 2204 amino acids with a calculated molecular weight of 248822. Mung bean nuclease mapping of the 5' terminus of the L gene mRNA indicates that the transcription of the L gene is initiated 11 nucleotides upstream of the translational start site. Comparison with the amino acid sequences of the L genes of Sendai virus and vesicular stomatitis virus (VSV) suggests that there are several regions of homology between the sequences. These data provide further evidence for an evolutionary relationship between the Paramyxoviridae and the Rhabdoviridae. A non-coding sequence of 46 nucleotides downstream of the presumed polyadenylation site of the L gene may be part of a negative strand leader RNA.

Abstract
We present the nucleotide sequence of bovine parainfluenza 3 virus (BPIV3) genome from its 3' end to the opening region of the F gene, through the NP, P plus C, and M genes. Comparison of the sequence with those reported for other paramyxoviruses indicated that BPIV3 was most similar to human parainfluenza 3 virus (HPIV3), and also very similar to Sendai virus in the structural make-up of its genome and the amino acid sequences of its gene products, suggesting that these three viruses constitute a paramyxovirus subgroup from which Newcastle disease and measles viruses are separable. In BPIV3 and Sendai virus, the NP and M proteins, the main structural elements, were more highly conserved than the functionally important P and C proteins. This tendency was also observed even in BPIV3 and HPIV3. Virus-specific amino acid sequences of the NP and M proteins were found at the carboxyl and amino terminal regions, respectively. BPIV3 M mRNA was found to have aberrations in its poly A attachment site.
