[PMID: 36283250 PMCID: PMC9925305 DOI: 10.1016/j.bmc.2022.117066] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2022] [Revised: 10/09/2022] [Accepted: 10/11/2022] [Indexed: 02/04/2023]
Abstract
Pertussis is a highly contagious respiratory disease caused by the Gram-negative bacterial pathogen, Bordetella pertussis. Despite high global vaccination rates, pertussis is resurging worldwide. Here we discuss the development of current pertussis vaccines and their limitations, which highlight the need for new vaccines that can protect against the disease and prevent development of the carrier state, thereby reducing transmission. The lipo-oligosaccharide of Bp is an attractive antigen for vaccine development as the anti-glycan antibodies could have bactericidal activities. The structure of the lipo-oligosaccharide has been determined and its immunological properties analyzed. Strategies enabling the expression, isolation, and bioconjugation have been presented. However, obtaining the saccharide on a large scale with high purity remains one of the main obstacles. Chemical synthesis provides a complementary approach to accessing the carbohydrate epitopes in a pure and structurally well-defined form. The first total synthesis of the non-reducing end pertussis pentasaccharide is discussed. The conjugate of the synthetic glycan with a powerful immunogenic carrier, bacteriophage Qβ, results in high levels and long-lasting anti-glycan IgG antibodies, paving the way for the development of a new generation of anti-pertussis vaccines with high bactericidal activities and biocompatibilities.

Abstract
We studied activity of Bordetella pertussis LPS in the LAL test. The mean activity of various series of LPS preparations obtained from B. pertussis cells ranged from 1,950,000 to 2,940,000 endotoxin units/μg (EU/μg). Activity of the LPS preparation obtained from the culture medium supernatant was significantly higher (4,640,000 EU/μg). Activity of the control standard E. coli 055:B5 LPS was 19,500±500 EU/μg. These data indicate that activity of the obtained preparations of B. pertussis LPS in the LAL test is 100-200 times higher than activity of E. coli LPS used as a reference control. It was concluded that the results of the LAL test when assessing the permissible content of B. pertussis endotoxins require correction, probably by introducing a correction factor.

Abstract
The immunogenicity of the pertussis vaccine can be significantly improved by adding Bordetella pertussis oligosaccharide with multiple trisaccharide units. The more trisaccharide units there are, the better the efficiency of the immune response induction. However, natural B. pertussis oligosaccharides usually contain only a single terminal trisaccharide unit. In addition, B. pertussis is pathogenic, and there are potential safety hazards when preparing oligosaccharides from B. pertussis. In this study, Escherichia coli MG1655 was engineered to produce B. pertussis oligosaccharides containing multiple trisaccharide units. Fifty-nine genes relevant to the biosynthesis of the O-antigen and core oligosaccharide of lipopolysaccharide, enterobacterial common antigen, and colanic acid were deleted in MG1655, resulting in strain MDCO020. Then, 25 genes relevant to the biosynthesis of the oligosaccharide antigen in B. pertussis and 3 genes relevant to the repeating trisaccharide unit in Pseudomonas aeruginosa PAO1 were overexpressed in MDCO020, resulting in the recombinant E. coli MDCO020/pWpBpD5. The production of B. pertussis oligosaccharide with multiple trisaccharide units by MDCO020/pWpBpD5 was confirmed by SDS-PAGE and 1H NMR analyses, and its immune response-stimulating activity was confirmed by using rabbit anti-pertussis serum.
