Abstract: The present disclosure is directed to compositions and methods of treating arthritogenic alphavirus infection. Compositions include a fusion protein comprising an Fc region, a first Mxra8 region, and a second Mxra8 region, wherein the fusion protein reduces inflammation and infection by an arthritogenic alphavirus. Methods include administering the fusion protein to a mammalian or non-mammalian subject to reduce or inhibit alphavirus infection.

Abstract: Compositions and methods for treating a viral infection may comprise use of a viral recognition-site inhibiting agent composition. A viral recognition-site inhibiting agent composition of the present disclosure may substantially inhibit, reduce, or block virus bind to the LDLRAD3 host receptor and reduces the infectivity of a virus for a host cell. A method of treating a viral infection may comprise administering a composition comprising a viral recognition-site inhibiting agent of the present disclosure, to a subject and reducing the infectivity of the virus for a host cell of the subject. The compositions may be administered via intranasal or systemic administration to treat or prevent a viral infection, for example an alphavirus infection.

Abstract: Among the various aspects of the present disclosure is the provision of compositions and methods of treating arthritogenic alphavirus infection and methods of screening.

Abstract: The present invention relates to previously undescribed viruses that are associated with significant expansion of the virome, immunodeficiency, and enteropathy during lentiviral infection. The invention also provides methods to detect acquired immune deficiency syndrome (AIDS) or AIDS progression in a subject, methods to diagnose immunodeficiency or enteropathy in a subject, and methods to identify a therapeutic agent to treat the same.

Abstract: Novel murine astroviruses, and methods of detecting the viruses are disclosed. Also disclosed are uses of the viruses and infected animals as model systems for discovery and development of vaccines and therapies for diseases caused by or associated with astrovirus infection, including human astrovirus-based diseases.
