The embodiments of the present disclosure relate to antigens of β-coronaviruses, preparation methods and uses thereof. The amino acid sequence of the antigen of the β-coronavirus includes an amino acid sequence arranged in a (A-B)-(A-B) pattern or an amino acid sequence arranged in a (A-B)-C-(A-B) pattern or an amino acid sequence arranged in a (A-B)-(A-B′) pattern or an amino acid sequence arranged in a (A-B)-C-(A-B′) pattern. The antigen of the β-coronavirus has a single-chain dimer structure. A single-chain dirtier expressed according to examples of the present disclosure is stable in content and has excellent immunogenicity as an antigen of a β-coronavirus, and a vaccine prepared by using the single-chain dimer as an antigen of a β-coronavirus can elicit high-titer neutralizing antibodies in mice.

Provided herein are methods and compositions related to a method of stimulating the immune system in a subject in need thereof by administering an agent that increases the level or activity of indoleamine 2,3-dioxygenase (IDO1) and/or aryl hydrocarbon receptor (Ahr).

The present invention provides methods for modulating the immune response of a subject to a therapeutic agent, the method comprising administering an effective amount of a triphenylethylene (TRIP) compound with an effective amount of the therapeutic agent. In particular embodiments, the TRIP compound enhances the immune response of the subject to the therapeutic agent. In some embodiments, the TRIP compound is administered in different dosing schedules to provide a biphasic immunomodulation effect.

The invention provides compositions including stabilized multilamellar lipid vesicles having crosslinked lipid bilayers (referred to herein as interbilayer-crosslinked multilamellar vesicles or ICMV) and including an ALK variant, pharmaceutical compositions containing vesicles (e.g., ICMV) including an ALK variant, and methods of treatment using such compositions. The invention provides compositions including stabilized multilamellar lipid vesicles with crosslinked lipid bilayers (e.g., an interbilayer-crosslinked multilamellar vesicle or ICMV) containing an Anaplastic lymphoma kinase (ALK) variant as an antigen that is associated with solid tumor cancers.
