A Brief Note On Rubella And Rubella - congratulate

Of the four reported cases of congenital rubella syndrome, only one was in a child whose mother had been born in the United States, the organizations note. In addition, there were fewer than 10 reported cases of rubella, or German measles, last year in the United States. These numbers contrast with figures from the early s, when about 11, fetal deaths resulted from rubella and 20, babies were born with congenital rubella syndrome. The joint statement credits the U. Continued surveillance for cases of congenital rubella syndrome is necessary, the statement stresses, as is maintaining high levels of childhood and adolescent vaccination, particularly in order to replicate this success worldwide.

Rubella virus RuV is the pathogenic agent of the disease rubellaand is the main cause of congenital rubella syndrome when infection occurs during the first weeks OOn pregnancy. Rubella virus is a member of the genus Rubivirus and belongs to the family A Brief Note On Rubella And Rubella Matonaviridaewhose members commonly have a genome of single-stranded RNA of positive polarity which is enclosed by an icosahedral capsid. Another member is Ruhugu virus. The molecular basis for the causation of congenital rubella syndrome is not yet completely clear, but in vitro studies with cell lines showed that rubella virus has an apoptotic effect on certain cell types. There is Brife for a p53 -dependent mechanism.

UntilRubiviruses were classified as article source of the family Togaviridaebut have since been changed to be the sole genus of the family Matonaviridae. This family is named after George de Maton, who in first distinguished rubella from measles and scarlet fever.

InRuhugu Rubellx and Rustrela virus joined Rubella virus as second and third of only three members of the genus Rubivirus. While alphavirus virions are spherical and contain an icosahedral nucleocapsidRuV virions are pleiomorphic and do not contain icosahedral nucleocapsids.

They concluded:. Phylogenetic analysis of the RNA-dependent RNA polymerase of alphaviruses, rubella virus and other positive-sense RNA viruses shows the two genera within the Togaviridae are not monophyletic. In particular, rubella virus groups more closely with members of the families BenyviridaeHepeviridae and Alphatetraviridaealong with several unclassified viruses, than it does with members A Brief Note On Rubella And Rubella the family Togaviridae belonging to the genus Alphavirus. The E1 glycoprotein is considered immunodominant in the humoral response induced against the structural proteins and contains both neutralizing and hemagglutinating determinants. There are three sites that are highly conserved in Matonaviruses: a stem-and-loop structure at the 5' end of the genome, a nucleotide conserved sequence near the 5' end of the genome and a nucleotide conserved sequence at the subgenomic RNA start site.

Homologous sequences are present in the rubella genome. The genome encodes several non-coding RNA structures; among Brlef is the rubella virus 3' cis-acting elementwhich contains multiple stem-loopsone of which has been found to be essential for viral replication. The only significant region of homology between rubella and the alphaviruses is located at the NH2 terminus of non structural protein 3.

This A Brief Note On Rubella And Rubella has helicase and replicase activity. In the rubella genome these occur in the opposite orientation to that found in the alphaviruses indicating that a genome rearrangement has occurred. The viruses attach to the cell surface via specific receptors and Charismatic Leader Of Adolf taken up by an endosome being formed. At the neutral pH outside of the cell the E2 envelope protein covers the E1 protein.

The dropping Ruubella inside the endosome frees the outer domain of E1 and causes the fusion of the viral envelope with the endosomal membrane. Thus, the capsid reaches the cytosoldecays and releases the genome.

This short subgenomic RNA is additionally packed in a virion. Translation of the structural proteins produces a large polypeptide Dalton. This is then endoproteolytically cut into E1, E2 and the capsid protein. E1 and E2 are type I OOn proteins which are transported into the endoplasmatic reticulum ER with the help of an N-terminal signal sequence.

The capsid proteins on the other hand stay in the Rubela and interact with the genomic RNA, together forming the capsid. The capsid protein CP has different functions. Further is it responsible for the aggregation of RNA in the capsid, it interacts with the membrane proteins E1 and E2 and binds the human host-protein p32 which is important for replication of the virus in the host.

As opposed to alpha viruses the capsid does not undergo autoproteolysis, rather is it cut off from the rest of the polyprotein by the signal- peptidase. Production of the capsid happens at the surface of intracellular membranes simultaneously with the budding of the virus. RuV is a respiratory-transmitted between humans.
