Epitope of dengue virus E protein detect human antibodies associated with mild disease: a potential peptide for vaccine development BJID
Sánchez-Burgos,Gilma; Herrera-Nájera,Carla; Cedillo-Rivera,Roberto; Dumonteil,Eric.
ABSTRACT The antigenic potential of seven immunogenic peptides of the dengue virus was evaluated in the sera of patients with dengue confirmed by IgM/IgG serology. Antibodies IgM and IgG against dengue virus peptides were analyzed by ELISA in 31 dengue sero-positive and 20 sero-negative patients. The P5 peptide showed significant IgG immunoreactivity mostly in the sera of patients with dengue without warning signs in comparison with patients with dengue with warning signs, correlating with mild disease. This finding suggests that the low antibody response against P5 epitope could be a risk factor for higher susceptibility to dengue virus infection with warning signs, and that P5 could be a potential antigen for vaccine development.

Induction of neutralizing antibodies against mutalysin-II from Lachesis muta muta Snake Venom Elicited by a conformational B-cell epitope predicted by Blue Star Sting data base. Repositório Alice
MACHADO-DE-ÁVILA, R. A.; VELLOSO, M.; OLIVEIRA, D.; STRANSKY, S.; FLOR-SÁ, A.; SCHNEIDER, F. S.; NESHICH, G.; CHÁVEZ-OLÓRTEGUI, C..
Mutalysin-II, from Lachesis muta muta snake venom, is an endopeptidase with hemorrhagic activity. To identify a conformational epitope we used Blue Star Sting, the latest version of the web based Sting Millenium Suite, as alternative computational analysis tool to select and design peptides. Pre-selected cut-off values of the accessibility and hydrophilicity parameters were used to select amino acid residues as potential conformational epitopes. A peptide (P117-Y116-C115-Q194-C195-L197-N198-K199-P200-Y5-L48) was manually drawn on Swiss-PDB-Viewer package and synthesized by Fmoc-synthesis. Immunization of rabbits with this peptide induced antibodies that recognized Mutalysin-II and protected against the hemorrhagic factors present in Lachesis venom. The...

Molecular characterization and T and B cell epitopes prediction of Mycoplasma synoviae 53 strain VlhA hemagglutinin Genet. Mol. Biol.
Camargo,Ilana Lopes; Fonseca,Cristina Toscano; Teixeira,Santuza Ribeiro; Azevedo,Vasco; Myioshi,Anderson; Oliveira,Sergio Costa.
Mycoplasma sinoviae is a major pathogen of poultry causing synovitis and respiratory infection. M. synoviae hemagglutinin (VlhA) is a lipoprotein encoded by related multigene families that appear to have arisen by horizontal gene transfer. It is an abundant immunodominant surface protein involved in host-parasite interaction mediating binding to host erythrocytes. Herein, we have performed in silico analysis of the vlhA gene product from the Mycoplasma synoviae 53 strain and compared it to the VlhA protein of M. synoviae WUV1853 strain. The VlhA of the M. synoviae 53 strain possesses 569 amino acids and showed 85% identity with the VlhA protein of the M. synoviae WUV1853 strain. Further, a signal peptide was identified from amino acid M1 to D28 and a...
