The Cysteine residues (C) are believed to be palmitoylated and this could serve to anchor the E2-tail at the surface of the inner membrane. Detection of Chikungunya Virus E1 by Western Blot. Arboviruses (or arthropod-borne viruses), represent a threat for the new century. Yes The chikungunya virus (CHIKV) is an arthropod-borne arbovirus belonging to the Alphavirus genus and Togaviridae family [1]. Both the overall lengths of the 3′-NTR and repeats have been drawn to scale. mosquitoes. Unable to load your collection due to an error, Unable to load your delegates due to an error. Wash area with soap and water for 15 minutes. Izza Nasrullah, Affiliation a The Illumina mapping data presented in the table were obtained in 2017 on samples that had been collected and found positive for chikungunya or dengue virus by real-time reverse transcription-PCR in 2016. b ‘R1 + R2’ indicates paired-end sequencing. However, it is also interesting to note that the mean GC% and AU% values are very similar (Table 1), yet the G/C- ending codons were used in a comparatively biased manner, indicating that the G/C content at the third position of the codons influenced the shaping of the overall synonymous codons usage patterns. Furthermore, a significant negative correlation between GC3 and ENC values was also observed (r = −0.756, P<0.01). Zika-infected Ae. Chikungunya virus and the mosquito vector Aedes aegypti in New Caledonia (South Pacific Region). The similarity index D(A,B) was therefore calculated for each genotype of CHIKV in relation to its hosts and vectors. Being parasitic organisms, it can be expected that the codon usage patterns of viruses would be affected by its hosts to some extent [33]. Chikungunya is generally spread through bites from Aedes aegypti mosquitoes, but the chikungunya virus strains in the 2005-2006 Reunion Island outbreak contained a mutation that facilitated transmission by Aedes albopictus (Tiger mosquito). Furthermore, all common preferred codons between CHIKV and H. sapiens were G/C- ended (C-ended: 7; G-ended: 4), with exception of an A-ended preferred codon for amino acid Arg. Inflammation & Immunology. In detail, the preferred codons for 12 out of 18 amino acids were common between CHIKV and H. sapiens. The DENV genome is about 11000 bases of positive-sense, single stranded RNA (ssRNA) that codes for three structural proteins ( capsid protein C, membrane protein M, envelope protein E) and seven nonstructural proteins (NS1, NS2a, NS2b, NS3, NS4a, NS4b, NS5). (A) Primary macrophages were…, Schematic representation of the capsid protein with the main interaction domains. The GenBank accession numbers of newly generated sequences are MT038393–409 (CHIKV) and MT040672–87 (DENV). The GC3 values ranged from 54.9% to 57.2%, with a mean of 55.86% and a standard deviation (SD) 0.40 compared with that of AU3, whose values ranged from 42.8% to 45.1%, with a mean of 44.14% and an SD of 0.41. Wear long sleeves and pants. The book gives a comprehensive overview on the knowledge of virus infection relevant for humans and animals. The ENC values among CHIKV genomes ranged from 54.55 to 56.41, with a mean of 55.56 and an SD of 0.34 (Table 1). This analysis was implemented based on the Spearman’s rank correlation analysis. Discover a faster, simpler path to publishing in a high-quality journal. Our data suggested that although mutation pressure dominates codon usage in CHIKV, patterns of codon usage in CHIKV are also under the influence of natural selection from its hosts and geography. The genetic code comprises 64 codons that can be divided into 20 groups, where each group consists of one to six codons, and each group corresponds to each of the standard amino acids. Found inside – Page iThis book gives an account of such a new approach, through clear tutorial contributions by leading scientists specializing in the different fields involved. The amino acid sequences of the E2 cytoplasmic domain from different viruses are shown. The vertebrate immune system relies on unmethylated CpG recognition in DNA molecules as a signature of infection, and CpG under-representation in RNA viruses is exclusively observed in vertebrate viruses; therefore, it is reasonable to suggest that a TLR9-like mechanism exists in the vertebrate immune system that recognizes CpGs when in an RNA context (such as in the genomes of RNA viruses) and triggers immune responses [45]. The N-terminal domain α-helix is indicated and the corresponding amino acid sequence is shown for CHIKV and related viruses. Chikungunya virus infections in 1,400 pregnant women, by onset or lack of symptoms, Réunion, France, 2006 Table 2. As a conservative criterion, for Pxy>1.23 (or <0.78), the XY pair is considered to be over-represented (or under-represented) in terms of relative abundance compared with a random association of mononucleotides. Found insideThis book was written during a period when the technologies of genetic engineering were being applied to the study of animal viruses and when the organization and function of individual virus genes were being elucidated. U3% had a significant positive correlation with U% (r = 0.621, P<0.01) and G% (r = 0.185, P<0.05), whereas it had significant negative correlations with C% (r = −0.606, P<0.01) A% (r = −0.278, P<0.01) and GC% (r = −0.806, P<0.01). Chikungunya virus (CHIKV), is a member of the genus Alphavirus, and family Togaviridae. Pregnancy outcome according to chikungunya virus infection during pregnancy, Réunion, France, 2006 All work involving infectious or potentially infectious material. Therefore, to determine the trends in codon usage variation among different CHIKV genomes, we performed COA on the RSCU values, which were examined as a single dataset based on the RSCU value of each coding region (Figure 3). The sequence of CHIKV is from Khan et al. Our results show that the overall codon usage bias and gene expression among different CHIKV genomes is lower, slightly biased and would be mainly affected by the base composition. The molecular architecture of the plasma membrane-associated replication complex from the Chikungunya virus is unknown. Chikungunya virus (CHIKV) is a significant human pathogen that causes debilitating and long-lasting arthritis. Chikungunya virus disease has caused numerous epidemics in Africa and Asia. CHIKUNGUNYA Dr.T.V.Rao MD . However, in case of CHIKV genomes, variations in nucleotide base compositions were noted (Table 1), indicating that other factors, such as natural selection, could also influence overall synonymous codon usage bias. Performed the experiments: AMB IN. Yes The Immunization Safety Review Committee was established by the Institute of Medicine (IOM) to evaluate the evidence on possible causal associations between immunizations and certain adverse outcomes, and to then present conclusions and ... The ENC is used to quantify the absolute codon usage bias of the gene (s) of interest, irrespective of gene length and the number of amino acids [30]. Would you like email updates of new search results? In the case of GC3%, positive correlation was noted with C% (r = 0.498, P<0.01) and GC% (r = 0.852, P<0.01), and negative correlation with U% (r = −0.480, P<0.01); the correlation with G% was non-significant. No, Is the Subject Area "China" applicable to this article? In December 2013, an outbreak of Chikungunya virus (CHIKV) caused by the Asian genotype was notified in the Caribbean. It has been proposed that CpG deficiency in pathogens is associated with the immunostimulatory properties of unmethylated CpGs, which are recognized by the host’s innate immune system as a pathogen signature [28]. It is an enveloped, positive-stranded RNA virus of ~11.8 kb whose genome encodes five structural proteins (capsid, E3, E2, 6K and E1) and four nonstructural proteins (nsP1–4) [2]. Severson DW, Behura SK. The mean CAI value was low, indicating low codon usage bias and expression levels, which agreed with the ENC analysis. The relative abundance of dinucleotides in the coding regions of CHIKV genomes was calculated using a previously described method [43]. Infectious clones of Chikungunya virus (La Réunion isolate) for vector competence studies. https://doi.org/10.1371/journal.pone.0090905.g001, https://doi.org/10.1371/journal.pone.0090905.t002. Like other RNA viruses with high mutation rates, CHIKV produces populations of genetically diverse genomes within a host. A descriptive and retrospective study was carried out using sera of patients infected with Chikungunya during the outbreak in Colombia. (A) between chikungunya virus (CHIKV), Homo sapiens (HS), Pan troglodytes (PT) and Aedes aegypti (AG) and Aedes albopictus (AB). The remaining 52 codons had RSCU values between 0.6–1.6 (Figure 1 and Table 2). Schnierle BS. Copyright: © 2014 Butt et al. 2021 Jul 20;10(7):1828. doi: 10.3390/cells10071828. Volk, SM et al. Chikungunya virus (CHIKV) is a member of the genus Alphavirus within the family Togaviridae and is transmitted by Aedes mosquitoes. In addition, we simulated two recombination events between these genomes: I—an ECSA 5’ region (7555bp) /Asian/Caribbean 3’ region (4646bp) genome; II—an Asian/Caribbean 5’ region (7555bp) /ECSA 3’ region (4257bp) genome; and a co-infection/quasispecies pattern all along the genome mixing equal proportion of reads generated from ECSA and Asian/Caribbean reference … … The conserved ribosome-binding sequence (amino acids 98 to 112) is indicated. The NetPhos sequence analysis (. revealed that the virus causing the Caribbean epidemics belongs to the Asian genotype [17]. In the case of ARO, an opposite trend was observed: ARO values were significantly negatively correlated with f′1 and correlations with f′2, ENC, GC3 and GC were not significant (Table 6). This book reviews the current status of antiviral therapy, from the roads to development of new compounds to their clinical use and cost effectiveness. This analysis showed that the three different genotypes of CHIKV might have common ancestor. Genes, whose codon choice is constrained only by a mutation bias, will lie on or just below the curve of the expected ENC values. A simplified phylogenetic tree of Alphaviruses assuming their New World origin, adapted from…, Organization of the CHIKV genome and gene products. This analysis collectively indicates that mutational pressure is most likely responsible for the patterns of nucleotide composition and, therefore, codon usage patterns, because the effects were present at all codon positions. The curve indicates the expected codon usage if GC compositional constraints alone account for codon usage bias. In the case of CpG-containing codons, all codons were under-represented (RSCU<1.6) and were not preferred codons for their respective amino acid, except for CCG (RSCU = 1.26), a preferred codon for proline (Table 2).

The structural proteins are synthesized as a long polyprotein, which is then posttranslationally cleaved into C, E1, 6K, and p62. Chikungunya virus outbreaks are characterized by rapid spread, and the disease manifests as acute fever. VEEV is actually a complex of 7 different species as well as multiple subtypes and varieties [3]. The RNA is contained within a protein shell, or capsid, which in turn is covered by a phospholipid layer, or envelope. A single chikungunya virion particle, which includes the capsid and envelope, is 60–70 nanometres in diameter. There are multiple strains of chikungunya virus, which differ from one another in their RNA sequences. Navien TN, Yeoh TS, Anna A, Tang TH, Citartan M. World J Microbiol Biotechnol. The systematic review was undertaken to provide data on incidence, the seroprevalence of anti-Chikungunya virus (CHIKV) IgM and IgG antibodies, mortality, the genotypes of circulating CHIKV and travel-related cases of chikungunya in the country.

For instance, the codon usage pattern of poliovirus is reported to be mostly coincident with that of its host [34], while the codon usage pattern of hepatitis A was reported to be antagonistic to that of its host [35]. It consists of a single stranded, positive sense RNA genome with two open reading frames (ORFs) [ ]. One possible explanation is that methylated cytosines are prone to mutate into thymines through spontaneous deamination, resulting in the dinucleotide TpG and the subsequent presence of a CpA on the opposite strand after DNA replication [47]. At titers ranging from 107–108 copies per milliliter, reads … Recognition of umethylated CpGs by Toll like receptor 9 (TLR9), a type of intracellular pattern recognition receptor (PRR), leads to activation of several immune response pathways [44]. Here, we calculated the CAI values of coding sequences from CHIKV genomes. Chikungunya virus and Aedes mosquitoes: saliva is … The bar corresponds to 100 nm. 2016;7(4):E58. Contributed articles. This book focuses on the mechanisms that viruses use to evolve, survive and cause disease in their hosts. CHIKUNGUNYA VIRUS• Two changes to the structure of E1 Makes the virus more likely to enter mosquito cells and replicate after the insect has fed on the blood of an infected person CHIKV: chikungunya virus; Ct: cycle threshold; DENV: dengue virus. This redundancy of the genetic code, in which most of the amino acids can be translated by more than one codon, represents a key step in modulating the efficiency and accuracy of protein production, while maintaining the same amino acid sequence of the protein. GENOME ANNOUNCEMENT. Chen R, Puri V, Fedorova N, Lin D, Hari KL, Jain R, et al. The accession numbers and other detailed information of the selected CHIKVs’ genomes, such as isolation date, isolation place, host and genome size were also retrieved (Table 7). COA involves a mathematical procedure that transforms some correlated variable (RSCU values) into a smaller number of uncorrelated variables called principal components. (B) between east central south African (ECSA), Asian and West African (WA) genotypes of CHIKV. Imported cases were found in Asia, Australia, USA, Canada and continental Europe. 11.7 kilobases long. Found insideFinally, all these characteristics make this book an excellent update on many subjects of world public health. (1998)). It has been suggested that if synonymous codon usage bias is affected by mutational pressure alone, then the frequency of nucleotides A and U/T should be equal to that of C and G at the synonymous codon third position [26]. Is the Subject Area "Chikungunya virus" applicable to this article? In the case of f2, A3%, G3% and C% had non-significant correlations. Chikungunya (CHIK) is currently endemic in South and Central India and exist as co-infections with dengue in Northern India. The different non-structural proteins (nsP1–nsP4) and structural proteins (C, Capsid; E1, E2, E3, envelope; 6K) are generated after proteolytic cleavage of polyprotein precursors. Contributed equally to this work with: Two more cases were reported in 1981. In addition to correlation analysis, linear regression analysis was also performed to determine correlations between the first two principle axes (f′1 and f′2) and nucleotide constraints of CHIKV genomes. [Aedes albopictus, vector of chikungunya and dengue viruses in Reunion Island: biology and control]. Secondly, we computed the effect of transmission vectors on the formation of the overall codon usage patterns of three genotypes of CHIKV. As shown in Table 1, the mean A% (28.91) was the highest, followed by similar composition of G% (25.75) and C% (25.19), with the U% being the lowest (20.16). polymerase only binds 3' end, "stutters" at polyU to form polyA, can either drop off or reinitiate downstream, controls ratio of proteins. Research Category. The analysis results showed that the GRAVY values were not significant for f′1 and were highly significant for f′2, ENC, GC3 and GC. 2008; Bradwell et al.

MABF2052, is a mouse monoclonal antibody that detects E2 protein of Chikungunya virus and has been tested for use in ELISA, Immunocytochemistry, Neutralizing asssay, and Western Blotting. The present study aimed to discover molecular signatures for comorbidity of viral infections. The overall codon usage bias was low in CHIKV genomes, as inferred from the analysis of effective number of codons (ENC) and codon adaptation index (CAI). Anti-Chikungunya virus, clone 3E7b, Cat. a The Illumina mapping data presented in the table were obtained in 2017 on samples that had been collected and found positive for chikungunya or dengue virus by real-time reverse transcription-PCR in 2016. b ‘R1 + R2’ indicates paired-end sequencing. Interestingly, GpC dinucleotides also deviated from the normal range and were instead slightly over-represented (mean ± SD = 1.001±0.007) (Table 5). Moreover, the similarity index of codon usage was also the highest between CHIKV and A. albopictus, as compared with A. aegypti, P. troglodytes and H. sapiens. (A) Primary macrophages were exposed to 25×TCID. Other symptoms may include headache, muscle pain, joint swelling, or rash. From RSCU analysis, we observed that CHIKV exhibits comparatively higher codon usage bias towards G/C- and less towards A-ended codons. The different steps of the CHIKV replication cycle are described in detail in this review. CHIKV, which belongs to the Alphaviruses genus, was not previously regarded as a highly pathogenic arbovirus. It was isolated for the first time from a Tanzanian outbreak in 1952 [ 3 ]. A general mutational pressure, which affects the whole genome, would certainly account for the majority of the codon usage among certain RNA viruses [21]. Azeem Mehmood Butt, Being an arthropod-borne virus, the mode of transmission is the mosquitoes of the Aedes spp. Chikungunya is a mosquito-borne viral disease first described during an outbreak in southern Tanzania in 1952. No specific treatment available. Zhou et al. Growth Conditions: Cell culture. A mixture of coincidence and antagonism has also been reported previously in the case of HCV [31] and enterovirus 71 [13]. Stay in places with air conditioning or that use window and door screens. Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed.) Chikungunya virus (CHIKV) is a re-emerging Alphavirus causing fever, joint pain, skin rash, arthralgia, and occasionally death. Particles found within the endosomes appear to be electron-dense. Chikungunya is a viral disease transmitted to humans by infected mosquitoes. It is caused by the chikungunya virus (CHIKV). A CHIKV infection causes fever and severe joint pain. Epub 2012 Nov 20. As for the effects of the two primates on the formation of the overall codon usage of CHIKV, the strongest effect of H. sapiens was on the Asian genotype, closely followed by the ECSA and WA genotypes. Outbreaks have occurred in countries in Africa, Asia, Europe, and the Indian and Pacific Oceans. Found insideThese diseases are called vector-borne zoonotic diseases.
