The invention relates to methods for modulating the neurological and immune function through targeting of acetylcholine (ACh) and CLIP. The result is wide range of new therapeutic regimens for treating, inhibiting the development of, or otherwise dealing with, a multitude of illnesses and conditions, including psychiatric or neurological disease, autoimmune disease, transplant and cell graft rejection, chronic wounds, non-neuronal immune disorders, Alzheimer's, Parkinson's Disease, Lewy Body dementia, pediatric acute neuropsychiatric syndromes (PANS), hypertension, late stage Ebola, Hantavirus, or coronavirus-induced hyperinflammatory conditions, including infections that cause a pathological “cytokine storm”, other post-infectious syndromes that result in cytokine storms in some people, and cancer, as well as novel methods of diagnosis and of introducing a treatment regimen into a subject and improving cognition and addiction cessation methods. In some embodiments the addiction is an addiction to smoking, alcohol and/or drugs.

Pan-coronavirus recombinant vaccine compositions featuring whole proteins or sequences of proteins encompassing all mutations in variants of human and animal Coronaviruses (e.g., 36 mutations in spike protein) or a combination of mutated B cell epitopes, mutated combination of B cell epitopes, mutated CD4+ T cell epitopes, and mutated CD8+ T cell epitopes, at least one of which is derived from a non-spike protein. The mutated epitopes may comprise one or more mutations. The present invention also describes using several immuno-informatics and sequence alignment approaches to identify several human B cell, CD4+ and CD8+ T cell epitopes that are highly mutated. The vaccine compositions herein have the potential to provide long-lasting B and T cell immunity regardless of human and animal Coronaviruses mutations.

Compositions and methods for treating a viral infection may comprise use of an adenoviral vector. An adenoviral vector of the present disclosure may comprise a non-human adenoviral genome with one or more gene locus functionally removed and a transgene. A method of treating a viral infection may comprise administering a composition comprising an adenoviral vector of the present disclosure, to a subject and reducing the infectivity or transmission of the virus. Intranasal administration provides enhance protection of the upper respiratory tract of a subject relative to intramuscular administration.

Provided are a cell-mediated SARS-COV-2 vaccine and a preparation method therefor, the steps therefor including: the construction of a SARS-COV-2 specific antigen vector presented by stem cells, and the modification and assembly with the stem cells. Two weeks after mouse immunization, approximately 50% of the mice have in vivo antibodies that show a strong positive expression, and the most significant of which being an N-gene modified stem cell vaccine.

Proteinaceous therapeutics, such as antibodies and fusion proteins, for preventing, reducing the occurrence of, and/or treating a SARS-CoV-2 infection in a subject are provided herein. The methods provided herein include administering to a subject an antigen binding fragments (Fab fragment) or antibody that binds to the S ARS-CoV-2 Spike protein, ACE2 decoy peptides that bind to the SAILS-CoV-2 Spike protein, and/or a DNA construct encoding an anti-Spike Fab fragment or ACE2 decoy peptide.

The present disclosure provides materials and methods related to engineered bacteria for use in vaccines. In particular, the present disclosure provides novel compositions and methods for generating vaccine compositions comprising bacteria (e.g., Lactobacillus) engineered to express immunogenic polypeptides and immunogenicity-enhancing adjuvant polypeptides to treat and/or prevent infection from a pathogenic organism (e.g., coronavirus).
