Dengue fever is the most important vector‐borne viral disease. Four serotypes of dengue virus, DENV1 to DENV4, coexist. Secondary infection by a different serotype is a risk factor for severe dengue. Monoclonal antibody mAb4E11 neutralizes the four serotypes of DENV with varying efficacies by recognizing an epitope located within domain‐III (ED3) of the viral envelope (E) protein. To better understand the cross‐reactivities between mAb4E11 and the four serotypes of DENV, we constructed… 

Antibody Binding Modulates Conformational Exchange in Domain III of Dengue Virus E Protein

This work provided one of the very rare descriptions of the effect of antibody binding on antigen dynamics, which was observed in the isolated DIII, in regions important for the packing of E protein dimers on the virus surface.

Characterization and epitope mapping of Dengue virus type 1 specific monoclonal antibodies

The results showed two selected mAbs DV1-E1 and DV2-E2 can specifically target and significantly neutralize DV1 and these two mAbs might be applied in the development of DV1 specific serologic diagnosis and used as a feasible treatment option for DV1 infection.

Meta-Analysis of Dengue Severity during Infection by Different Dengue Virus Serotypes in Primary and Secondary Infections

Evidence is provided that the presence of certain serotypes, including primary infection withDENV-3 from the Southeast Asia region and secondary infection with DENV-2, DENv-3, and DenV-4 also from the SEA region, as well as DENV -2 and DENV3 from non SEA regions, increased the risk of severe dengue infections.

DNA Switch: Toehold-Mediated DNA Isothermal Amplification for Dengue Serotyping

A DNA sensor designed to function like a switch to turn “on” silver nanocluster (AgNC) generation in the presence of a specific DNA target, able to distinguish each dengue serotype by generating the serotype-respective AgNCs.

The Evolution of Molecular Recognition: From Antibodies to Molecularly Imprinted Polymers (MIPs) as Artificial Counterpart

MIPs, indeed, are more versatile and cost-effective than conventional antibodies, but the lack of toxicity studies and their scarce use for practical applications, make it that further investigations on this kind of molecules need to be conducted.

Structural basis for cross-reactivity and conformation fluctuation of the major beech pollen allergen Fag s 1

The Nuclear Magnetic Resonance (NMR) structure of Fag s 1 is presented along with its dynamic properties, and it exhibits the expected three α-helices and seven β-sheets arranged as a semi-beta barrel and exposing the residues mapped as the Bet v 1 IgE epitope.

Diversity and junction residues as hotspots of binding energy in an antibody neutralizing the dengue virus

The genetic events that led to mAb4E11 during an immune response are recreated and an alanine scanning mutagenesis of its third hypervariable loops are performed and changes of residues that statistically do not participate in the contacts between antibodies and antigens but determine the structure of L‐CDR3 decreased the affinity between mAb 4E11 and its antigen.

Structural insights into the neutralization mechanism of a higher primate antibody against dengue virus

It is shown that human sera from patients recovering from DENV‐4 infection contain antibodies that bind to the 5H2 epitope region on domain I, which provides new information and tools for effective vaccine design to prevent dengue disease.

Structural Analysis of a Dengue Cross-Reactive Antibody Complexed with Envelope Domain III Reveals the Molecular Basis of Cross-Reactivity

The characterization of a mAb, 2H12, is reported, which is cross-reactive to all four serotypes in the dengue virus group and provides a structural basis for understanding Ab neutralization and enhancement of infection, which are crucial for the development of future d Dengue vaccines.

Cross-reactivities between human IgMs and the four serotypes of dengue virus as probed with artificial homodimers of domain-III from the envelope proteins

The serotype specificity and cross-reactivity of human IgMs directed against ED3 is determined by using a well-characterized collection of 90 DENV-infected and 89DENV-uninfected human serums to help better understand the IgM immune response and protection against DENV.

Mapping to completeness and transplantation of a group-specific, discontinuous, neutralizing epitope in the envelope protein of dengue virus.

The energetic epitope of antibody mAb4E11, which neutralizes the four serotypes of DENV but no other flavivirus, and binds domain 3 of their envelope glycoprotein, was characterized and mechanisms for its neutralization potency are suggested.

Variable Surface Epitopes in the Crystal Structure of Dengue Virus Type 3 Envelope Glycoprotein

The crystal structure of a soluble fragment of the envelope glycoprotein E from dengue virus type 3 is determined and shows that neighboring glycans on the viral surface are spaced widely enough that they can interact with multiple carbohydrate recognition domains on oligomeric lectins such as DC-SIGN, ensuring maximum affinity for these putative receptors.

Structural Basis of Differential Neutralization of DENV-1 Genotypes by an Antibody that Recognizes a Cryptic Epitope

The results support the conclusion that potent neutralization depends on genotype-dependent exposure of the CC′ loop epitope, and establish new structural complexity of the DENV virion, which may be relevant for the choice of DENV strain for induction or analysis of neutralizing antibodies in the context of vaccine development.

Mapping of a dengue virus neutralizing epitope critical for the infectivity of all serotypes: insight into the neutralization mechanism.

The data suggest that the DE(306-314) segment is critical for the infectivity of all dengue virus serotypes and that molecules that block the binding of DE( 306- 314) to HSHS may be antiviral reagents of therapeutic interest.
