Hemagglutinin Sequence Conservation Guided Stem Immunogen Design from Influenza A H3 Subtype
Seasonal epidemics caused by influenza A (H1 and H3 subtypes) and B viruses are a major global health threat. The traditional, trivalent influenza vaccines have limited efficacy because of rapid antigenic evolution of the circulating viruses. This antigenic variability mediates viral escape from the host immune responses, necessitating annual vaccine updates. Influenza vaccines elicit a protect...
متن کاملA stable trimeric influenza hemagglutinin stem as a broadly protective immunogen.
The identification of human broadly neutralizing antibodies (bnAbs) targeting the hemagglutinin (HA) stem revitalized hopes of developing a universal influenza vaccine. Using a rational design and library approach, we engineered stable HA stem antigens ("mini-HAs") based on an H1 subtype sequence. Our most advanced candidate exhibits structural and bnAb binding properties comparable to those of...
متن کاملInfluenza hemagglutinin stem-fragment immunogen elicits broadly neutralizing antibodies and confers heterologous protection.
Influenza hemagglutinin (HA) is the primary target of the humoral response during infection/vaccination. Current influenza vaccines typically fail to elicit/boost broadly neutralizing antibodies (bnAbs), thereby limiting their efficacy. Although several bnAbs bind to the conserved stem domain of HA, focusing the immune response to this conserved stem in the presence of the immunodominant, varia...
متن کاملSequence Analysis and Phylogenetic Study of Hemagglutinin Gene of H9N2 Subtype of Avian Influenza Virus Isolated during 1998-2002 in Iran
Sequence analysis and phylogenetic study of hemagglutinin (HA) gene of H9N2 subtype of avian influenza virus isolates (outbreaks of 1998-2002) in Tehran province (Iran) were studied. Two sets of forward and reverse primers in highly conserved regions, based on sequences of HA gene in Genbank, were designed. PCR products of a 430-bp fragment of 16 isolates were sequenced and then were aligned wi...
متن کاملCharacterization of a novel influenza A virus hemagglutinin subtype (H16) obtained from black-headed gulls.
In wild aquatic birds and poultry around the world, influenza A viruses carrying 15 antigenic subtypes of hemagglutinin (HA) and 9 antigenic subtypes of neuraminidase (NA) have been described. Here we describe a previously unidentified antigenic subtype of HA (H16), detected in viruses circulating in black-headed gulls in Sweden. In agreement with established criteria for the definition of anti...
