Download or read book Measles Virus Nucleoprotein written by Sonia Longhi and published by Nova Publishers. This book was released on 2007 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measles virus possesses a non segmented, single stranded, negative sense RNA genome that is encapsidated by the nucleoprotein to form a helical nucleocapsid. This ribonucleoproteic complex is the substrate for both transcription and replication. The RNA-dependent RNA polymerase binds to the nucleocapsid template via its co-factor, the phosphoprotein. This book focuses on the main structural information available on the nucleoprotein, showing that it consists of a structured core (NCORE) and of an intrinsically disordered C-terminal domain (NTAIL). The functional implications of the disordered nature of NTAIL are discussed in light of the ability of disordered regions to establish interactions with multiple partners, thus leading to multiple biological effects. Indeed, beyond the phosphoprotein, NTAIL also interacts with cellular partners, including the major heat shock protein, hsp72, the interferon regulator factor 3, IRF3, and a yet unidentified cellular receptor referred to as NR. This book consists of two chapters devoted to the general functions of the nucleoprotein in transcription and replication and to a detailed overview of its structural properties, and of three chapters focused on the functional relevance of the interaction between NTAIL and its various intracellular and extracellular partners.
Download or read book Measles Virus written by Volker ter Meulen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measles, also called the greatest killer of children in history, still annually affects about 50 million individuals and causes close to a million deaths primarily in developing countries. Before the advent of measles vaccine some 30 years ago, these figures were roughly three times higher. Attenuated measles virus (MV) strains, all quite closely related to the original Edmonston isolate, have a very good record as a safe and highly efficacious vaccine and have brought down the measles toll in industrialized countries to almost negligible levels. However, recent outbreaks in the USA and Europe have again brought the measles problem to public attention. Sadly enough, these outbreaks were more instrumental in inducing activities to drastically reduce and hopefully finally eradicate measles than were the ten thousand times higher number of victims in developing countries. To reach this goal, as detailed in this volume, apparently it is not enough to of the existing vaccine as was the rigorously enforce use case with smallpox eradication: the intricacies of measles disease phenomena, in particular the generalized immune suppression which favors secondary infections, require more basic knowledge of the virus-host interactions and probably the development of new vaccines for special applications such as first immunizations of very young infants in developing countries.
Download or read book Measles written by Diane E. Griffin and published by Springer Science & Business Media. This book was released on 2008-10-30 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measles virus, one of the most contagious of all human viruses, has been largely contained by the development and use of a vaccine that was introduced 50 years ago. These two volumes were timed to honor the introduction of the vaccine and to record the enormous advancements made in understanding the molecular and cell biology, pathogenesis, and control of this infectious disease. Where vaccine has been effectively delivered, endemic measles virus transmission has been eliminated. However, difficulties in vaccine delivery, lack of health care support and objection to vaccination in some communities continue to result in nearly 40 million cases and over 300,000 deaths per year from measles.
Download or read book Measles Virus microform Immunoprecipitation and Monoclonal Antibody Production written by David John Paul Rafter and published by National Library of Canada. This book was released on 1981 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antisera to the membrane (M) protein and to the nucleoprotein (NP) of measles virus, were prepared in rabbits. Each of the antisera was characterized by the immunoprecipitation technique and found to be monospecific. These monospecific antisera were used to determine, by indirect immunofluorescence, the cellular location of M-protein and NP during infection. The antiserum to M-protein stained the cytoplasm of Vero cells. The NP antiserum stained both the cytoplasm and nucleus. The NP was found to undergo breakdown in infected cells. This breakdown could be inhibited by aprotinin, a protease inhibitor specific for trypsin and chymotrypsin. As no protease function has been identified for the proteins of measles virus, it is believed that the proteolysis is a cellular function. The significance of proteolytic breakdown in the assembly of measles virus is discussed. Persons who receive inactivated measles vaccine and are subsequently exposed to wild type virus may experience atypical measles. It has been postulated that these individuals are susceptible to atypical measles because the inactivated vaccine fails to induce antibodies to the F-protein as detected by hemolysis-inhibition. Matched (acute and convalescent) serum samples were analyzed by the immunoprecipitation technique. Sera taken during the acute stage of the disease did not precipitate radiolabelled F-protein. Convalescent sera, which had been collected three weeks later, did precipitate the F-protein. The absence of antibodies to F confirms the earlier work obtained by hemolysis inhibition tests. These findings support the concept that atypical measles is the result of an absence of antibodies to F-protein. Once it was recognized that atypical measles appeared following the use of inactivated vaccines, an attenuated virus vaccine was introduced for widespread immunization programs. This vaccine was also used in "catch up" programs to reimmunize individuals who had previously received "killed" vaccine. The value of this "catch up" program was analyzed using matched serum samples obtained from children previously immunized with inactivated virus vaccine, who volunteered for reimmunization with the attenuated vaccine. Since in no case was reimmunization found to result in conversion to the production of antibody to F-protein, the attempt to irradicate atypical measles by this procedure should be re-evaluated. The monoclonal antibody technique was employed to obtain a series of monospecific antibodies to the measles virus proteins. In initial experiments 17 clones secreting antibody to the measles Lee strain were obtained. Of these, two clones have been established as stable cell lines. Both of these clones secrete antibody specific for the NP of the virus.

Download or read book Negative Strand Rna Virus written by Ming Luo and published by World Scientific. This book was released on 2011-08-05 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: Negative strand RNA viruses have a unique mechanism of replication. Their genome is a single strand RNA that has to be transcribed as soon as the virus enters the host in order to carry out viral replication. As a result, a viral-specific RNA polymerase is packaged in the virion and is ready for transcription after virus entry. This novel replication mechanism dictates the assembly and RNA synthesis of negative strand RNA viruses. In recent years, many discoveries have been made with regard to the entry, replication and assembly of this class of viruses. This book will present updated coverage of the fundamental knowledge about negative strand RNA viruses.
