Antigenic and Genetic Variability of Human Metapneumoviruses
Human metapneumovirus (HMPV) is a member of the subfamily Pneumovirinae within the family Paramyxo- viridae. Other members of this subfamily, respiratory syncytial virus and avian pneumovirus, can be divided into subgroups on the basis of genetic or antigenic differences or both. For HMPV, the existence of different genetic lineages has been described on the basis of variation in a limited set ...
متن کاملConstraints on the Genetic and Antigenic Variability of Measles Virus
Antigenic drift and genetic variation are significantly constrained in measles virus (MeV). Genetic stability of MeV is exceptionally high, both in the lab and in the field, and few regions of the genome allow for rapid genetic change. The regions of the genome that are more tolerant of mutations (i.e., the untranslated regions and certain domains within the N, C, V, P, and M proteins) indicate...
متن کاملExpression and Antigenic Evaluation of VacA Antigenic Fragment of Helicobacter Pylori
Objective(s): Helicobacter pylori, a human specific gastric pathogen is a causative agent of chronic active gastritis. The vacuolating cytotoxin (VacA) is an effective virulence factor involved in gastric injury. The aim of this study was to construct a recombinant protein containing antigenic region of VacA gene and determine its antigenicity. Materials and Methods: The antigenic region of V...
متن کاملCorrelation between antigenicity and variability in the vls antigenic variation system of Borrelia burgdorferi.
Many parasites have evolved antigenic variation systems that alter surface proteins in order to evade recognition by presently expressed antibodies and subsequent death. Although the amino acid positions in antigens to which antibodies most commonly target are expected to be the most variable, this assumption has not been investigated. Using the vls antigenic variation system of Borrelia burgdo...
متن کاملAntigenic and molecular analyses of the variability of bovine respiratory syncytial virus G glycoprotein.
Antigenic variation among eight bovine respiratory syncytial virus (BRSV) isolates was determined using monoclonal antibodies (MAbs) specific for the attachment (G) protein. Two major (and one intermediate) subgroups were identified, as well as one strain that did not fit any pattern. The subgroups could also be differentiated on the basis of the Mr of the F protein cleavage product, F2. The nu...
