摘要:
The present invention provides a balloon which achieves diameters greater than 6 mm for securement to a catheter. The balloon includes an elastomeric generally hollow pressure expandable body which exhibits essentially radial symmetry and constant length when expanded under an internally applied minimum working pressure from an uninflated state.
摘要:
Described herein is a method of eliciting antibodies and neutralizing of binding antibodies against a hepatitis C virus (HCV) E1E2 or E2 antigen using HCV E2 or HCV E1E2 polypeptides and/or HCV E2 or E1E2 polynucleotides. Elicitation of anti-E2 antibodies and anti-E2 NOB antibodies can be used, inter alia, to provide model systems to optimize anti-E2 antibody responses and/or anti-E2 NOB antibody responses to HCV and to provide prophylactic or therapeutic treatment against HCV infection.
摘要:
Immunogenic compositions for use in treating, preventing and diagnosing infection caused by the California (CAL) serotype of the genus Bunyavirus, such as La Crosse virus (LACV), are disclosed. Also described are reagents for use in diagnostic assays.
摘要:
Polypeptides comprising a mutant non-structural Hepatitis C virus useful in diagnostic and/or immunogenic compositions are disclosed, in which the mutant is an N-terminal mutation that functionally disrupts the catalytic domain of NS3. Polynucleotides encoding these polypeptides, host cells transformed with polynucleotides and methods of using the polypeptides and polynucleotides are also disclosed.
摘要:
Immunogenic compositions that elicit immune responses against Norovirus and Sapovirus antigens are described. In particular, the invention relates to polynucleotides encoding one or more capsid proteins or other immunogenic viral polypeptides from one or more strains of Norovirus and/or Sapovirus, coexpression of such immunogenic viral polypeptides with adjuvants, and methods of using the polynucleotides in applications including immunization and production of immunogenic viral polypeptides and viral-like particles (VLPs). Methods for producing Norovirus- or Sapovirus-derived multiple epitope fusion antigens or polyproteins and immunogenic compositions comprising one or more immunogenic polypeptides, polynucleotides, VLPs, and/or adjuvants are also described. The immunogenic compositions of the invention may also contain antigens other than Norovirus or Sapovirus antigens, including antigens that can be used in immunization against pathogens that cause diarrheal diseases, such as antigens derived from rotavirus.
摘要:
The invention provides a method of activating hepatitis C virus (HCV)-specific T cells, including CD4+ and CD8+ T cells. HCV-specific T cells are activated using fusion proteins comprising HCV NS3, NS4, NS5a, and NS5b polypeptides, polynucleotides encoding such fusion proteins, or polypeptide or polynucleotide compositions containing the individual components of these fusions. The method can be used in model systems to develop HCV-specific immunogenic compositions, as well as to immunize a mammal against HCV.

摘要:
Two Hepatitis C Virus envelope proteins (E1 and E2) are expressed without sialylation. Recombinant expression of these proteins in lower eukaryotes, or in mammalian cells in which terminal glycosylation is blocked, results in recombinant proteins which are more similar to native HCV glycoproteins. When isolated by GNA lectin affinity, the E1 and E2 proteins aggregate into virus-like particles.
摘要:
The present invention provides a stretchable material suitable for use in an inflatable medical device. The stretchable material has at least one reinforcing polymer layer with a top and bottom side forming a porous matrix which is imbibed with a sealing material to infiltrate and substantially seal spaces of the porous matrix and extend beyond the reinforcing polymer layer to form a surface coating.
