A method fits reversing immune suppression or immune exhaustion or for treating a disease associated with immune suppression includes: administering a co position to a subject in need of such treatments wherein the composition contains a CD11b modulator that binds specifically to CD11b on a cell to inhibit PD-L1 expression. The CD11b modulator is an antibody or an antigen-binding portion thereof, or a compound as described.

This document relates to methods and materials for treating a mammal having an autoimmune disease. For example, materials and methods for producing an immuno-activatable cell comprising a first chimeric antigen receptor and a second chimeric antigen receptor are provided. Methods and materials for treating a mammal having an autoimmune disease comprising administering an immuno-activatable cell are also provided.

Described are methods of treating or preventing an inflammatory disease or condition caused by excessive expression, secretion, or concentration of alpha synuclein. The methods comprise administering compositions that reduce the effective concentration of alpha-synuclein present in the surrounding tissues. In addition, the invention encompasses methods of inhibiting alpha-synuclein interaction with CD11b, comprising administering an agent that binds to alpha-synuclein to prevent binding productively to the integrin CD11b, or administering an active agent that interacts with CD11b on an immune cell to prevent alpha-synuclein from directing chemotaxis of that cell. In addition, the invention discloses a method of identifying an individual with a condition amenable to treatment targeting alpha-synuclein CD11b interaction.

The present disclosure provides modified antibodies which contain an antibody or antibody fragment (AB) modified with a masking moiety (MM). Such modified antibodies can be further coupled to a cleavable moiety (CM), resulting in activatable antibodies (AAs), wherein the CM is capable of being cleaved, reduced, photolyzed, or otherwise modified. AAs can exhibit an activatable conformation such that the AB is more accessible to a target after, for example, removal of the MM by cleavage, reduction, or photolysis of the CM in the presence of an agent capable of cleaving, reducing, or photolyzing the CM. The disclosure further provides methods of making and using such modified antibodies and activatable antibodies.

Provided herein are methods for producing site specific PEG modifications to single domain antibodies (e.g., VHHs). Methods for producing site-specific ally conjugated bivalent single domain antibodies (e.g., VHHs) are also provided. Methods for labeling (e.g., with a fluorophore or radionuclide) site-specifically PEGylated single domain antibodies and site-specifically conjugated bivalent single domain antibodies are also provided.

The present invention concerns methods of diagnosing and treating a malignant neoplasm of the CNS by detecting mammalian tissue expressing integrin alpha 10 subunit or a fragment or variant thereof, and administering a drug specific for integrin alpha 10 subunit.

Masking domains and masked antibodies comprising masking domains are provided. In some embodiments, masked antibodies comprising the masking domains demonstrate minimal aggregation and low potential for immunogenicity. In various embodiments, masked antibodies comprising the masking domains may be used in therapeutic treatment.
