IMMUNOMODULATORY PROTEINS WITH TUNABLE AFFINITIES

Provided herein are human interferon alpha-2 (IFNA2) variants that have decreased or no detectable binding to the human interferon-alpha/beta receptor beta 2 (IFNAR2) as compared to the wild-type human IFNA2 polypeptide. Also provided herein are fusion proteins comprising an antibody or fragment thereof, and a human IFNA2 variant, wherein the IFNA2 variant is covalently linked to the antibody, and wherein the IFNA2 variant has decreased or no detectable binding to the human interferon-alpha/beta receptor beta (IFNAR2) as compared to the wild-type human IFNA2 polypeptide.

Interferon alpha-2 variants

Provided herein are variant CTLA-4 polypeptides and immunomodulatory proteins and nucleic acids encoding such proteins. The immunomodulatory proteins provide therapeutic utility for a variety of disease applications, including for treatment of autoimmune or inflammatory conditions. Compositions and methods for making and using such proteins are provided.

CTLA-4 variant immunomodulatory proteins and uses thereof

Provided herein are multi-domain immunomodulatory proteins, nucleic acids encoding such immunomodulatory proteins, cells engineered to express the immunomodulatory proteins and infectious agents containing nucleic acid encoding the immunomodulatory proteins. The immunomodulatory proteins bind both an inhibitory receptor and a receptor involved in activation signaling cascades in an immune cell, such as a T cell. The immunomodulatory proteins, engineered cells and infectious agents provide therapeutic utility for a variety of immunological diseases or conditions. Compositions and methods for making and using such proteins are provided.

Multi-domain immunomodulatory proteins and methods of use thereof

The disclosure provides interleukin 21 (IL-21) variants that have (i) decreased or no binding to a human interleukin 21 receptor (IL-21R) as compared to a wild-type human IL-21 polypeptide; or (ii) increased stability as compared to a wild-type human IL-21 polypeptide; or (iii) decreased or no binding to a human interleukin 21 receptor (IL-21R) as compared to a wild-type human IL-21 polypeptide and increased stability as compared to a wild-type human IL-21 polypeptide. The disclosure also provides fusion proteins including an antibody or fragment thereof bound, e.g., covalently linked, to an IL-21 variant.

Interleukin 21 variants

Provided herein are immunomodulatory proteins comprising ICOSL variants and nucleic acids encoding such proteins. The immunomodulatory proteins provide therapeutic utility for a variety of immunological and oncological conditions. Compositions and methods for making and using such proteins are provided.

ICOS ligand variant immunomodulatory proteins and uses thereof

Provided herein are immunomodulatory proteins comprising variant PD-1 polypeptides, nucleic acids encoding such proteins and engineered cells expressing such proteins. The immunomodulatory proteins provide therapeutic utility for a variety of immunological and oncological conditions. Compositions and methods for making and using such proteins are provided.

PD-1 variant immunomodulatory proteins and uses thereof

Provided herein are immunomodulatory proteins comprising variant CD112 and nucleic acids encoding such proteins. The immunomodulatory proteins provide therapeutic utility for a variety of immunological and oncological conditions. Compositions and methods for making and using such proteins are provided.

CD112 variant immunomodulatory proteins and uses thereof

Provided herein are immunomodulatory proteins comprising variant PD-L2 and nucleic acids encoding such proteins. The immunomodulatory proteins provide therapeutic utility for a variety of immunological and oncological conditions. Compositions and methods for making and using such proteins are provided.

PD-L2 variant immunomodulatory proteins and uses thereof

Provided herein are variant CD80 polypeptides, immunomodulatory proteins comprising variant CD80 polypeptides, and nucleic acids encoding such proteins. The immunomodulatory proteins provide therapeutic utility for a variety of immunological and oncological conditions. Compositions and methods for making and using such proteins are provided.

CD80 variant immunomodulatory proteins and uses thereof

Variant ICOS ligand immunomodulatory proteins and related compositions and methods

Provided herein are immunomodulatory proteins comprising variant CD155 and nucleic acids encoding such proteins. The immunomodulatory proteins provide therapeutic utility for a variety of immunological and oncological conditions. Compositions and methods for making and using such proteins are provided.
