An evaluation system for replication activity of HBV capable of visualizing and quantifying replication of HBV DNA in a short period of time inexpensively, safely, and rapidly and a method for evaluation using the system are developed and provided. Moreover, a novel composition for inhibiting HBV replication with a mode of action different from that of conventional anti-HBV drugs is developed and provided. A therapeutic agent for hepatitis B comprising as an active ingredient an HBV-Pol activity inhibitor consisting of a phosphorylation inhibitor that inhibits phosphorylation of a TxY motif present in Terminal protein region of HBV-Pol is provided.

The present disclosure generally relates to hepadnavirus core antigens in which one or more endogenous b cell epitopes have been effectively removed. More specifically, the present disclosure relates to rodent hepadnavirus cores modified to diminish the antibody response to the core so as to enhance the antibody response to heterologous polypeptides included therein.

The present invention relates to the discovery of compositions and methods for therapeutic immunization for treatment of chronic hepatitis B. Methods of the invention include a method generating an evolved high titer hybrid-hepatitis B virus (HBV) vector, methods of treating and/or preventing HBV, and methods of inducing a memory T and B cell immune response against HBV infection in a subject administered the VLV composition produced thereby. Furthermore, the invention encompasses a pharmaceutical composition for vaccinating a subject to protect the subject against infection with HBV.

Disclosed herein are DNA-based vaccines against amyloid peptide for use in treating and alleviating Alzheimer's Disease and related conditions. A DNA construct comprising DNA encoding one or more amyloid peptides, such as amino acids 1-11 of A, and DNA encoding a hepatitis B antigens, is administered with an adjuvant or by electroporation. The vaccine can also be formulated using a fusion protein expressed by the disclosed DNA, in combination with an adjuvant.

The present invention provides an agent for the treatment or prophylaxis of arteriosclerosis comprising an expression vector encoding a chimeric Hepatitis B virus core antigen polypeptide inserted with an amino acid sequence containing a specific epitope of apolipoprotein (a), wherein the amino acid sequence containing the specific epitope is inserted between the amino acid residues 80 and 81 of the hepatitis B virus core antigen polypeptide.

The present invention relates to tumor immunotherapy, in particular to tumor vaccination, using chimeric proteins comprising all or a portion of a hepatitis B virus core antigen protein and an amino acid sequence comprising an epitope derived from the extracellular portion of a tumor-associated antigen. In particular, the present invention provides virus-like particles comprising said chimeric proteins, which are useful for eliciting a humoral immune response in a subject against the tumor-associated antigen, in particular against cells carrying said tumor-associated antigen on their surface, wherein the tumor-associated antigen is a self-protein in said subject.

The embodiments of the present disclosure relate to one or more compositions or methods that upregulate the production of one or more sequences of micro-interfering ribonucleic acid (miRNA). The sequences of miRNA may be complimentary to a sequence of target messenger RNA (mRNA) that encodes for translation of a target biomolecule, such as CXCR2. The miRNA can cause the target mRNA to be degraded or inactivated, thereby causing a decrease in bioavailability of the target biomolecule because it is degraded or inactivated by the miRNA. Decreasing the bioavailability of the target biomolecule within a subject that is administered the one or more compositions may address the afflictions experienced by the subject due to expression of the target biomolecule.
