The present disclosure relates to compositions and methods for treating or preventing a disease or disorder of immunoprivileged tissue. It is described herein that an immunogenic composition which induces production of memory CD4 T cells allows for the access of a therapeutic antibody to the immunoprivileged tissue.

A safe and effective vaccine to prevent, slow, halt or reverse progression of Alzheimer's disease in human patients is disclosed. The vaccine includes Aβ1-42 or an beta amyloid self epitope (e.g. Aβ1-15, or other 7-mer or 15-mer peptide epitopes derived from Aβ1-42) conjugated to an immunogenic carrier (e.g. DT) formulated in a water-in-oil Th2-biased adjuvant/delivery system.

A mutated tau protein fragment and a use thereof are disclosed. The mutated tau protein fragment consists 12 amino acid residues and thus can easily be prepared. In addition, when the mutated tau protein fragment is injected into an individual as an antigen, a neutralizing antibody against the mutated tau protein is generated. Moreover, the mutated tau protein fragment reduces the aggregation of abnormal tau proteins. Accordingly, the mutated tau protein fragment can be effectively used for the prevention or treatment of degenerative neurological diseases.

Liposomes containing tau peptides, preferably phosphorylated tau peptides, and conjugates containing tau peptides, preferably phosphorylated tau peptides, conjugated to an immunogenic carrier are described. Pharmaceutical compositions and uses of the liposomes and/or conjugates for treating or preventing a neurodegenerative disease or disorder, such as Alzheimer's Disease, are also described.

Provided are a cell secreted-type amylospheroids-like structure, a drug and vaccine using the same, as well as a method of producing the same. In one aspect, the present disclosure relates to a production method including a step of culturing, in a culture medium, cells that express an amyloid precursor protein (APP) or a part thereof containing an amyloid beta-protein (Aß) sequence to obtain a cell secreted-type amylospheroids (ASPD)-like structure in said culture medium.

The disclosure provides methods of tolerizing or treating a subject suffering from an autoimmune or autoinflammatory disease or disorder to an antigen associated with the autoimmune disease or disorder. The disclosure also features kits for carrying out the methods.

Binding members for sodium channel Nav1.7 and their use in medicine including for treatment of pain or epilepsy. Binding members comprise a fusion protein containing a Nav1.7-binding peptide, e.g., venom toxin peptide or knottin (“donor diversity scaffold domain”) inserted within an antibody variable domain (“recipient diversity scaffold domain”), and a partner domain (e.g., antibody variable domain), optionally wherein the partner domain enhances specificity of binding to Nav1.7 over other sodium channels.

The disclosure pertains to N-terminal epitopes identified in A-beta, including conformational epitopes, antibodies thereto and methods of making and using immunogens and antibodies specific thereto.

Methods for diagnosing and treating Alzheimer's disease are provided. In particular, methods of restoring blood-brain barrier integrity and/or promoting vascular reversion in a person suffering from Alzheimer's disease by administering an anti-angiogenic agent or an agent that is capable of restoring tight junction integrity. Methods of preventing or delaying the onset of Alzheimer's disease in a subject are also provided.

The present disclosure is directed to individual peptide immunogen constructs targeting portions of the Tau protein for the treatment and/or prevention of tauopathies. The present disclosure is also directed to compositions containing the peptide immunogen constructs, methods of making and using the peptide immunogen constructs, and antibodies produced by the peptide immunogen constructs.
