The invention features multi-specific fusion protein complexes with one domain comprising IL-15 or a functional variant and a binding domain specific to IL-12 or IL-18.

This disclosure relates to populations and compositions of purified cancer cell-derived vesicles and uses thereof.

The invention provides humanized mouse anti-human IL-31 antibodies and antibody fragments that are capable of binding IL-31 and thereby neutralizing, inhibiting, limiting, or reducing the proinflammatory or pro-pruritic effects of IL-31.

The present disclosure provides T cell modulatory polypeptide-epitope conjugates (T-Cell-MP-epitope conjugates) comprising a chemical conjugation site at which an NY-ESO (e.g., NY-ESO-1 or NY-ESO-2) or a MAGE (e.g., MAGEA4) peptide epitope is covalently attached and at least one immunomodulatory polypeptide sequence that may be variant selected to exhibit reduced binding affinity to its cognate co-immunomodulatory polypeptide. The T-Cell-MP-epitope conjugates are useful for modulating the activity (e.g., increasing proliferation or cytotoxic activity) of T-cells specific to the NY-ESO or MAGE peptide epitope in an epitope selective/specific manner, and accordingly, for treating individuals with, for example, cancers expressing the covalently attached epitope. The disclosure also provides T-Cell-MP-epitope conjugates with targeting sequences that can server to, among other things, localize the T-Cell-MP-epitope conjugates to a specific tissue or cell type.

The present disclosure provides T cell modulatory polypeptide-epitope conjugates (T-Cell-MP-epitope conjugates) comprising a chemical conjugation site at which a coronavirus peptide epitope is covalently attached and at least one immunomodulatory polypeptide sequence. The T-Cell-MP-epitope conjugates are useful for modulating the activity (e.g., increasing proliferation or cytotoxic activity) of T-cells specific to the coronavirus peptide epitope in an epitope selective/specific manner, and accordingly, for treating individuals with a coronavirus infection including long COVID. Alternatively, when the T-Cell-MP-epitope conjugate is redirected to a neoplastic cell by a targeting sequence, the redirected T-Cell-MP-epitope conjugate may be used to treat neoplasms including various cancers.

The present invention relates to an immunostimulatory composition comprising a) an adjuvant component, comprising or consisting of at least one (m)RNA, complexed with a cationic or polycationic compound, and b) at least one free mRNA, encoding at least one therapeutically active protein, antigen, allergen and/or antibody, wherein the immunostimulatory composition is capable to elicit or enhance an innate and optionally an adaptive immune response in a mammal. The inventive immunostimulatory composition may be a pharmaceutical composition or a vaccine. The invention furthermore relates to a method of preparation of the inventive immunostimulatory composition. The invention also relates to the use of the inventive immunostimulatory composition or its components (for the preparation of a pharmaceutical composition or a vaccine) for the treatment of various diseases. Finally, the invention relates to kits containing the inventive immunostimulatory composition, its components and/or the pharmaceutical composition or vaccine.

The present invention relates to agents that modulate interlekin-15 (IL-15) signal transduction or function (Therapeutic Agents) and the use ol those agents to modulate immune function. The Therapeutic Agents target the interaction between IL-15 and its receptor and modulate IL-15-induced signal transduction. The Therapeutic Agents may be formulated with polymers, such as poly--1-.diamond-solid.4-N-acetylglucosamine. for administration to a human subject to modulate IL-15-mediated immune function.

Combination therapeutics for the treatment of cancer include the use of immune effector cells, IL-15 based superagonists and one or more immunotherapeutic agents such as Bacillus Calmette-Guerin (BCG).

The invention features multi-specific fusion protein complexes with one domain comprising IL-15 or a functional variant and a binding domain specific to IL-12 or IL-18.

The present invention provides a vaccine composition containing a complex of a T cell receptor antigen peptide and a B cell receptor antigen peptide and capable of inducing the production of an antibody against IL-23, wherein the B cell receptor antigen peptide is represented by the following formula (I):

X1-X2-X3-X4-X5-X6-X7-X8 (I)

wherein X1 is S, A, G, T, K, or R, X2 is P, A, G, S, T, K, or R, X3 is S, A, G, T, K, or R, X4 is Q, A, G, T, or N, X5 is P, A, G, S, T, Q, or N, X6 is W, A, Y, or E, X7 is Q, A, G, T, or N, and X8 is R, A, G, or K.
