A Synthetic Conjugate Polysaccharide Vaccine Against Haemophilus influenzae Type b
The large-scale synthesis, pharmaceutical development, and clinical evaluation of a conjugate vaccine composed of a synthetic capsular polysaccharide antigen of Haemophilus influenzae type b (Hib) demonstrate that access to synthetic complex carbohydrate–based vaccines is feasible and provides a basis for further development of similar approaches for other human pathogens.
Novel ACE2-Independent Carbohydrate-Binding of SARS-CoV-2 Spike Protein to Host Lectins and Lung Microbiota
Novel ACE2-independent carbohydrate-mediated interactions with immune modulating lectins expressed on myeloid cells, as well as host lung microbiota glyco-conjugates are revealed, that may contribute to viral infection and subsequent immune exacerbation.
Molecular Aspects Concerning the Use of the SARS-CoV-2 Receptor Binding Domain as a Target for Preventive Vaccines
This review summarizes with a critical view the molecular aspects associated with the interaction of SARS-CoV-2 RBD with its receptor in human cells, the angiotensin-converting enzyme 2 (ACE2), the epitopes involved in the neutralizing activity, and the impact of virus mutations thereof.
Design and Biological Assembly of Polyester Beads Displaying Pneumococcal Antigens as Particulate Vaccine.
Insight is provided into the design of PHB beads as a carrier of proteinaceous antigens and CPS in order to induce immune responses for the prevention of pneumococcal infections.
Enzyme‐linked immunosorbent assay for quantitative determination of capsular polysaccharide production in Streptococcus pneumoniae clinical isolates
This ELISA allowed selection of an appropriate vaccine strain, for a natural polysaccharide vaccine, among several 23F pneumococcal clinical isolates and constituted a valuable analytical tool for Strep.
Synthesis of Neoglycolipids Containing Oligosaccharides Based on 3,6-Branched-α-D-Mannopyranosides as the Carbohydrate Moieties
Abstract Several oligosaccharides containing 3,6-branched-α-D-mannopyranosides were obtained by selective glycosylation of 5-azido-3-oxapentyl α-D-mannopyranoside with acetobromosugars. After
Effectiveness of a Serogroup B and C Meningococcal Vaccine Developed in Cuba.
In addition to prevention of meningococcal disease caused by homologous serogroup B strains, VA-MENGOC-BC should be considered for heterologous contexts, which is protective against serogroups C in all age groups.
In-solution buffer-free digestion for the analysis of SARS-CoV-2 RBD proteins allows a full sequence coverage and detection of post-translational modifications in a single ESI-MS spectrum
In this work, several recombinant RBD proteins produced in five expression systems were characterized using a non-conventional protocol known as in-solution buffer-free digestion (BFD), and it is foresee that it can be also helpful to the characterization of mutated RBD.
Synthetic, Zwitterionic Sp1 Oligosaccharides Adopt a Helical Structure Crucial for Antibody Interaction
This study has revealed the Sp1 nona- and dodecasaccharides as promising synthetic antigens, displaying all (3D) structural elements required to mimic the natural polysaccharide and required to unravel the molecular mode of action of these unique zwitterionicpolysaccharides.
