Abstract: The present invention relates to a method of producing HPV pseudovirions in plant cells, the plant produced pseudovirions per se, a neutralization assay using the plant produced pseudovirions and pharmaceutical compositions comprising the plant produced pseudovirions.

Abstract: The invention relates to a method for purifying compositions containing virus-like particles (VLP), wherein a VLP-containing composition is filtered through a filter medium, in particular through a membrane, having a molecular weight cut off (MWCO) of more than 30 kDa, and the cell culture supernatant of VLP-expressing cells is used as a VLP-containing composition. The invention further relates to a VLP-containing composition which can be produced by this method.

Abstract: A vaccination method is provided. The method comprises administering to a mammal a histone deacytelase inhibitor in conjunction with a vaccine that expresses an antigen to which the mammal has a pre-existing immunity.

Abstract: Provided is designer nucleic acid constructs and polypeptides that can be used as therapeutic vaccines against HPV18 and/or HPV16.

Abstract: Disclosed are yeast-based immunotherapeutic compositions, human immunodeficiency virus (HIV) antigens, and fusion proteins for the treatment and/or prevention of HIV infection and symptoms thereof, as well as methods of using the yeast-based immunotherapeutic compositions, HIV antigens, and fusion proteins for the prophylactic and/or therapeutic treatment of HIV and/or symptoms thereof.

Abstract: The present invention relates to the technical field of porcine pseudorabies virus, and more particularly to a porcine pseudorabies virus (PRV)-YF strain, with the preservation No. of CCTCC No. V201502. The present invention also provides an application of the porcine pseudorabies virus (PRV)-YF strain in preparing an inactivated vaccine of the porcine pseudorabies virus, the inactivated vaccine of the porcine pseudorabies virus and a preparation method thereof. It is proved through an immune efficacy evaluating test and a safety test that the inactivated vaccine of the porcine pseudorabies virus has good immune protective efficacy and is safe for weaned piglets, replacement gilts, pregnant sows and the like.

Abstract: Provided are an N-terminal truncated L1 protein of the Human Papillomavirus Type 58, a coding sequence and preparation method thereof, and a virus-like particle comprising the protein. Uses of the protein and the virus-like particle in the preparation of a pharmaceutical composition or a vaccine are further provided. The pharmaceutical composition or vaccine is used for prevention of HPV infection and a disease caused by HPV infection.

Abstract: The present invention includes the Paramyxovirus Parainfluenza Virus 5 (PIV5) as an oncolytic agent for treating various cancers, including, but not limited to breast cancer, lung cancer and melanoma. PIV5 oncolytic agents include both wild type PIV5 and various recombinant PIV5 constructs. Recombinant PIV5 constructs may include PIV5 lacking the conserved C-terminus of the V protein (PIV5VAC), PIV5 with mutations in the N-terminus of the V/P protein (PIV5CPI?), and PIV5 expressing MDA-7/IL-24 (rPIV5-MDA7), rPIV5-V/P-CPI?, rPIV5-CPI+, rPIV-Rev, rPIV5-RL, rPIV5-P-S157A, rPIV5-P-S308A, rPIV5-L-A1981D, rPIV5-F-S443P, rPIV5-MDA7, rPIV5ASH-CPI?, or rPIV5ASH-Rev. Also included are methods of making and using such oncolytic agents and compositions including such oncolytic agents.

Abstract: In one aspect, a method of treating cancer in a mammal is provided. The method comprises administering to the mammal an oncolytic vector that expresses a tumor antigen to which the mammal has a pre-existing immunity. In another aspect, a method of boosting immune response in a mammal having a pre-existing immunity to an antigen is provided comprising intravenous administration to the mammal of a B-cell infecting vector that expresses the antigen.

Abstract: This invention relates to a method for treating or preventing a disease by raising an innate immune response in a subject, the method comprising administering to the subject an effective amount of a composition comprising a TLR2 moiety in solution, wherein the TLR2 moiety comprises a TLR2 agonist and wherein the disease is not treated or prevented by a humoral or cellular immune response directed against the TLR2 moiety.

Abstract: Embodiments of the disclosure concern methods and compositions for immunotherapy for human papillomavirus infection and diseases associated therewith. In specific embodiments, methods concern production of immune cells that target one or more antigens of HPV16 and/or HPV18, including methods with stimulation steps that employ IL-7 and IL-15, but not IL-6 and/or IL-12. Other specific embodiments utilize stimulations in the presence of certain cells, such as costimulatory cells and certain antigen presenting cells.

Abstract: Recombinant truncated human furin was expressed in CHO cells and concentrated approximately 50-fold by ultrafiltration and diafiltration. The concentrate was purified by column chromatography on CAPTO MMC™ (mixed cation exchange/hydrophobic interaction gel) resulting in a 30-50 fold purification factor and a yield of at least 60%. The at least 20% pure preparation obtained after CAPTO MMC™ (mixed cation exchange/hydrophobic interaction gel) chromatography had already a purification degree allowing on-column maturation of pro-VWF. Then an additional Arginine Sepharose chromatography purification was carried out. This two column process for purification of truncated human furin resulted in an almost pure furin preparation with a specific activity of approximately 290,000 U furin/mg protein and a yield of about 50%.
