In particular, amino acid sequences in the RSV G glycoprotein, containing the chemokine motif defined as C-X-X-X-C (or CX3C), are identified that are essential in causing RSV infection and disease. The chemokine motif is biologically active and participates in virus binding to and infection of susceptible cells. The prevention or treatment of RSV infection is achieved by interfering with the motif, such as by administering a vaccine in which the motif is altered or by administration or induction of blocking molecules that inhibit the biological activity of the motif.Type: GrantFiled: January 25, 2012Date of Patent: July 15, 2014Assignee: The United States of America, as represented by the Secretary, Department of Health and Human ServicesInventors: Ralph A.

Patent number: 8765141Abstract: We have generated novel molecularly marked FMDV A24LL3DYR and A24LL3BPVKV3DYR vaccine candidates. The mutant viruses contain a deletion of the leader coding region (LL) rendering the virus attenuated in vivo and negative antigenic markers introduced in one or both of the viral non-structural 3Dpol and 3B proteins. The vaccine platform includes unique restriction endonuclease sites for easy swapping of capsid proteins for different FMDV subtypes and serotypes. The mutant viruses produced no signs of FMD and no shedding of virulent virus in cattle. No clinical signs of disease or fever were observed and no transmission to in-contact animals was detected in pigs inoculated with live A24LL3DYR. Cattle immunized with chemically inactivated vaccine candidates showed an efficacy comparable to a polyvalent commercial FMDV vaccine. These vaccine candidates used in conjunction with a cELISA provide a suitable target for DIVA companion tests.Type: GrantFiled: June 9, 2011Date of Patent: July 1, 2014Assignee: The United States of America, as represented by the Secretary of AgricultureInventors: Aida E.

Publication number: 20140127261Abstract: Mutations in the central monomer contact interface of the flavivirus envelope protein which modulate the infectivity of the flavivirus are made. The mutations decrease the ability of the envelope dimer protein to dissociate.Type: ApplicationFiled: November 7, 2012Publication date: May 8, 2014Applicant: Southern Research InstituteInventor: Vladimir Yamshchikov
