Fifty patients with congestive cardiomyopathy have been studied for evidence of previous Coxsackie B virus infection and compared with age- and sex-matched controls who had been admitted to hospital for investigation of other cardiac diseases. High neutralisation titres (greater than or equal to 1024) to Coxsackie B viruses were more common among the controls. On subdividing the patients according to their length of symptomatic history before study, high titres were more common only in those with a short history (less than or equal to 1 year). High titres were more common when there had been a febrile illness at the onset of symptoms. Endomyocardial biopsies of 18 patients disclosed no evidence of myocarditis, or, in 12 cases, of viral involvement. Although the evidence remains circumstantial, these results support the theory that Coxsackie B viruses may cause congestive cardiomyopathy and encourage further research into the mechanisms of myocardial cell damage by these visuses. ...
Coxsackievirus is a virus that belongs to a family of nonenveloped, linear, positive-sense single-stranded RNA viruses, Picornaviridae and the genus Enterovirus, which also includes poliovirus and echovirus. Enteroviruses are among the most common and important human pathogens, and ordinarily its members are transmitted by the fecal-oral route. Coxsackieviruses share many characteristics with poliovirus. With control of poliovirus infections in much of the world, more attention has been focused on understanding the nonpolio enteroviruses such as coxsackievirus. Coxsackieviruses are among the leading causes of aseptic meningitis (the other usual suspects being echovirus and mumps virus). The entry of coxsackievirus into cells, especially endothelial cells, is mediated by Coxsackie virus and adenovirus receptor. Coxsackieviruses are divided into group A and group B viruses based on early observations of their pathogenicity in neonatal mice. Group A coxsackieviruses were noted to cause a flaccid ...
Coxsackie B4 Virus are enteroviruses that belong to the Picornaviridae family. These viruses can be found worldwide. They are positive-sense, single-stranded, non-enveloped RNA viruses with icosahedral geometry. Coxsackieviruses have two groups, A and B, each associated with different diseases. Coxsackievirus group A is known for causing hand-foot-and-mouth diseases while Group B, which contains six serotypes, can cause a varying range of symptoms like gastrointestinal distress myocarditis. Coxsackievirus B4 has a cell tropism for natural killer cells and pancreatic islet cells. Infection can lead to beta-cell apoptosis which increases the risk of insulitis. Coxsackievirus B4 is one of the six serotypes found in Group B and is a positive sense, single-stranded, non-enveloped RNA virus. Its genome is linear and is 7,293 nucleotides in length with both a 5 and 3 untranslated region and encodes its own 3 poly-A tail. The 5 untranslated region contains an internal ribosomal entry site (Type I ...
Receptor binding and subsequent cell-mediated internalization or disassembly are the initial steps in virus replication. Cell surface molecules that participate in this process are the primary determinants of virus tissue tropism. Monoclonal antibody blockade, immunoprecipitation, and DNA transfection were used to identify decay accelerating factor as a major cell attachment receptor for coxsackieviruses B1, B3, and B5. However, expression of human decay acceleration factor on the surface of nonpermissive murine fibroblasts led only to virus attachment without subsequent replication, and it was concluded that an additional cellular cofactor(s) is required to facilitate cell entry and subsequent replication.
Interest in CAR stems from its function as the primary high affinity receptor for Ad serotype 5, the most commonly used adenoviral vector in gene therapy protocols. CAR expression is the main determinant in gene transfer to normal tissue as ectopic expression of CAR in transgenic mice leads to several magnitudes of increase in adenovirus transducibility of tissues that are otherwise refractory to Ad-mediated gene expression [13-17]. As well, although decay accelerating factor (DAF, CD55) was the first described CVB receptor [18, 19], CAR is necessary and sufficient for CVB infection in vitro [20]. Thus, the expression levels of CAR may also govern the susceptibility to CVB diseases and the pathological consequences of CVB viral infection. In this context, acute viral myocarditis and myositis are inflammatory diseases affecting cardiac and skeletal muscle that can result from infection by the Coxsackie B virus. In both humans and rodents, heart is among the tissues showing the greatest abundance ...

Full Text - Coxsackie B3 virus (CVB3) is a member of small RNA viruses that belongs to the genus Enterovirus of the family Picornaviridae and CVB3 is the main pathogen of acute and chronic viral myocarditis. In this study RT-qPCR was used to determine the expression of miR-107 in CVB3-infected and uninfected HeLa cells. The experimental results show that the level of miR-107 began to rise at 4 h after the infection, and significantly boosted at 6 h. Based on the results of this experiment, we consider that miR-107 expression is related to CVB3 infection. In order to further clarify the effect of miR-107 in the process of CVB3 infection, we studied the effect of miR-107 upstream and downstream target genes on CVB3 replication. Levels of the target RNAs were detected by RT-qPCR after CVB3 infection, and the expression of CVB3 capsid protein VP1 by western blot analysis. Then the virus in the supernatant was quantitated via a viral plaque assay, reflecting the release of the virus. The experimental results

Editorial comment: Cunningham and his associates determined whether enterovirus sequences were present in muscle biopsy specimens obtained from patients with PVFS. Two classes of probes were used: (i) so-called generic probes that were enterovirus group-specific; and (ii) probes that made it possible to determine whether virus RNA synthesis was asymmetrical (typical of cytic infection) or symmetrical (typical of defective viral RNA synthesis). Importantly, appropriate probes were used to test whether specimens also were positive for EBV sequences. Seventeen patients were studied that had fatigue for six or more months. Of these, five were mates and 13/17 were at midlife, i.e., 35-55 years of age. Then patients were tested for neutralizing antibody to Coxsackievirus B3; five were negative. Eleven patients were tested for IgM to Coxsackievirus B2, 3 and 5; of these, 10 were negative. Such results indicate that antibodies to Coxsackieviruses are not good surrogate markers for PVFS. When muscle ...

There is no vaccine to prevent coxsackievirus infection. Hand washing is the best protection. Remind everyone in your family to wash their hands frequently, particularly after using the toilet (especially those in public places), after changing a diaper, before meals, and before preparing food. Shared toys in childcare centers should be routinely cleaned with a disinfectant because the virus can live on these objects for days.. Kids who are sick with a coxsackievirus infection should be kept out of school or childcare for a few days to avoid spreading the infection.. The duration of an infection varies widely. For fever without other symptoms, a childs temperature may return to normal within 24 hours, although the average fever lasts 3 to 4 days. Hand, foot, and mouth disease usually lasts for 2 or 3 days; viral meningitis can take 3 to 7 days to clear up.. ...

N2 - Coxsackievirus B (CVB) is one of the major pathogens of aseptic meningitis and meningioencephalitis, particularly in newborn infants. To analyze the influence of neural maturation on susceptibility to CVB infection, we prepared immature and mature neurons from 16-day-old BALB/c embryonic cortex. In contrast to immature neurons, mature neurons were less susceptible to CVB5 infection, as indicated by the decrease of cytopathic features. In mature neurons, progeny virus production was significantly hindered, and virus capsid protein VP1 synthesis and virus genome amplification were concomitantly reduced. In addition, the expression of coxsackievirus and ...

Infection of people with human immunodeficiency virus (HIV) as well as LP- BM5 infection in mice results in progressive deterioration of the immune system in the majority of untreated hosts. Peptide immunotherapy has been shown to be effective in the stimulation or immunoregulation of T-helper 1 (TH1) and T-helper 2 (TH2) response subsets. In murine acquired immunodeficiency syndrome (AIDS), TH1 deficiency enables the host to be susceptible to coxsackievirus infection, inducing cardiopathology in a short period. T-cell receptor (TCR) V 8.1 peptide, a 16-mer peptide containing the entire CFR1 segment and part of the FR2 region of human V 8, showed both an immunoregulating and immunostimulating effect in murine AIDS. TCR V 8.1 peptide acts on T cells promoting interleukin-2 production and therefore enhancing a cellmediated immune response. It retarded development of cardiopathology due to coxsackievirus infection. Retrovirus infected mice treated with the peptide showed a longer life span than the ...
Group B coxsackieviruses (CVB) are associated with viral-induced heart disease and are among the leading causes of aseptic meningitis worldwide. Here we show that CVB entry into polarized brain microvasculature and aortic endothelial cells triggers a depletion of intracellular calcium stores initiated through viral attachment to the apical attachment factor decayaccelerating factor. Calcium release was dependent upon a signaling cascade that required the activity of the Src family of tyrosine kinases, phospholipase C, and the inositol 1,4,5-trisphosphate receptor isoform 3. CVB-mediated calcium release was required for the activation of calpain-2, a calcium-dependent cysteine protease, which controlled the vesicular trafficking of internalized CVB particles. These data point to a specific role for calcium signaling in CVB entry into polarized endothelial monolayers and highlight the unique signaling mechanisms used by these viruses to cross endothelial barriers. © 2010 Bozym et al.. ...

PDTC has been reported to possess strong antiviral activity against replication of influenza virus, rhinovirus, and poliovirus. However, the mechanism was not well elucidated (24, 58). In the current study, we have explored the manner in which PDTC inhibits both coxsackievirus B3 (CVB3) viral RNA synthesis and virus structural protein expression. We provide evidence that PDTC exerts its antiviral activity intracellularly, most likely independent of viral entry.. Divalent metal ions including copper and zinc have been reported to play an essential role in mediating various biological functions of PDTC (11, 13, 20, 30). Studies by Furuta et al. and Kim et al. suggest that PDTC may act as an ionophore, recruiting extracellular copper and zinc into the cells (23, 31). Treatment with PDTC resulted in an increase of intracellular zinc and redox reactive Cu2+, and depletion of extracellular copper and zinc prevented PDTC-induced cell death and inhibition of NF-κB activation. In the present study, we ...

腸道病毒(Enterovirus)又稱腸病毒,是一種主要寄生於腸道的正股單股RNA病毒,和人類及哺乳類的疾病有關。雖然名為腸病毒,在人類卻很少出現腸道的病狀。在病毒分類中,屬於第IV類的RNA病毒。腸道病毒的命名主要以它的英文名稱Enterovirus的英文簡寫EV,再後綴以數字命名。例如,近年在亞洲和北美洲流行、可以引起手足口病的EV71就是其中的一種。 常見的腸病毒有克沙奇病毒,又稱柯薩奇病毒(Coxsackievirus groups A and B)有A型(甲型)23種與B型(乙型)6種,Echovirus伊科病毒31種,和造成小兒麻痺症的Poliovirus脊髓灰质炎病毒3種,以及不分類的腸病毒68~71型。共67種。 腸病毒全球皆有分布,而人類是唯一宿主及唯一感染源。腸病毒具高傳染性,主要經由兩途徑傳染,經由吃到被汙染的食物、水、玩具、口水等或經由呼吸道(飛沫、咳嗽 ...
In this study, we demonstrated for the first time that a cardiotropic enterovirus, CVB3, transiently induced proinflammatory cytokines, IL-6 and IL-8, in human myocardial fibroblasts, a simplified but species-specific model to detect both cytokine expression and actions of cytokines.21 25 Moreover, the kinetics of CVB3-induced cytokine expression in myocardial fibroblasts was clearly divergent from dermal fibroblasts (Figure 2⇑), indicating an organ-specific pattern of induction.. Previously, the expression of IL-1β, IL-4, IL-6, IL-8, and TNF-α had been demonstrated by RT-PCR in the myocardium of patients suffering from enterovirus myocarditis, cryptogenic myocarditis, and dilated cardiomyopathy,17 18 but neither the cytokine-expressing cells (myocardial or infiltrating) nor the stimulus (virus or secondary to infiltration) had been unequivocally identified. Recently, Seko et al26 compared the cytokine expression in murine CVB3 myocarditis with that of CVB3-infected murine heart cells in ...
Myocarditis is mainly caused by cardiotropic viruses. In recent time viruses found in endomyocardial biopsies mainly consist of parvovirus B19 (PVB19) and human herpesvirus 6 (HHV6). A definite causal link between virus-genome detection of PVB19 and/or HHV6 (via pcr techniques)and cardiac inflammation and dysfunction is however still missing.. Primary objective:. To determine the prevalence of PVB19 and HHV6 virus genome in heart muscle biopsies of cardiac surgery patients without clinical evidence of myocarditis or myocarditic sequelae. Secondary objectives:. ...
Type 1 diabetes (T1D) is characterized by the destruction of the insulin-producing β-cells of pancreatic islets. Genetic and environmental factors both contribute to T1D development. Viral infection with enteroviruses is a suspected trigger for T1D but a causal role remains unproven and controversial. Studies in animals are problematic because of species-specific differences in host cell susceptibility and immune responses to candidate viral pathogens such as coxsackie B virus (CVB). In order to resolve the controversial role of viruses in human T1D, we developed a viral infection model in immunodeficient mice bearing human islet grafts. Hyperglycemia was induced in mice by specific ablation of native β-cells. Human islets, which are naturally susceptible to CVB infection, were transplanted to restore normoglycemia. Transplanted mice were infected with CVB4 and monitored for hyperglycemia. Forty-seven percent of CVB4-infected mice developed hyperglycemia. Human islet grafts from infected mice
c. Viral Infection and Generation of Pancreatitis. It has been shown that CVB3 replication, as well as the pathogenesis induced by CVB3 infection in the heart of mice is dependent upon the strain of virus and the strain of mice used in the study (12, 42). It is important to note that the virulence and, perhaps, the course of the disease depend upon the specific strain of virus and the genetic make up of the mice, some virus strains being avirulent and some mouse strains being more resistant to the virus than others (14, 34). Because of this, the viral inoculum will vary depending on the strain of mice and virus used. If a virulent virus strain is used in a susceptible strain of mice all animals will develop pancreatitis. CVB3/CO and CVB3/28 cause overt pancreatic damage in C57BL/6 or Balb/c mice. In contrast, CVB3/GA infects the pancreas but does not cause histological damage (33, 34). Mice are maintained on standard lab chow and water ad libitum unless experimental procedures require otherwise. ...

Through the more recent advancements in CAD CAM a new, much more accurate, predictable workflow is now available for comprehensive cases. This does not necessarily replace a diagnostic wax up, but in many cases, it can. It involves milling of a CVB prior to fabrication of the definitive restoration. The protocol includes an intraoral try-in of a final case design prior to fabrication of the definitive restoration. By doing so, one can check intraorally all the essential design elements and parameters. A CVB is a milled PMMA (polymethyl methacrylate) try-in bridge. The CVB is essentially a milled acrylic bridge that is milled from a CAD design intended to be used for the final restoration. Once the try-in is performed and evaluated, the original CVB design can be brought back to the CAD stage and altered or tweaked as needed to insure predictability and accuracy of the final restoration. Here is how it works ...
