As used herein, “protein” as used herein refers to a large molecule composed of one or more chains of amino acids in a specific order. The term protein is used interchangeable with “polypeptide.” The order is determined by the base sequence of nucleotides in the gene coding for the protein. Proteins are required for the structure, function, and regulation of the body's cells, tissues, and organs. Each protein has a unique function. The term protein as used herein can also include peptides. Thus, for example, an “effector protein” can include both effector proteins and effector peptides.

When the interaction of the two species produces a non-covalently bound complex, the binding that occurs is typically electrostatic, hydrogen-bonding, or the result of lipophilic interactions. Accordingly, “specific binding” occurs between a paired species where there is interaction between the two which produces a bound complex having the characteristics of an antibody/antigen, enzyme/substrate, DNA/DNA, DNA/RNA, DNA/protein, RNA/protein, RNA/amino acid, receptor/substrate interaction. In particular, the specific binding is characterized by the binding of one member of a pair to a particular species and to no other species within the family of compounds to which the corresponding member of the binding member belongs. Thus, for example, an antibody preferably binds to a single epitope and to no other epitope within the family of proteins.

Many variations and modifications may be made to the disclosed embodiment(s) of the disclosure without departing substantially from the spirit and principles of the disclosure. All such modifications and variations are within the scope of this disclosure.
Now having described the embodiments of the present disclosure, in general, the following Examples describe some additional embodiments of the present disclosure. While embodiments of the present disclosure are described in connection with the following examples and the corresponding text and figures, there is no intent to limit embodiments of the present disclosure to this description. On the contrary, the intent is to cover all alternatives, modifications, and equivalents included within the spirit and scope of embodiments of the present disclosure.
Indoleamine 2,3-dioxygenase (IDO), an enzyme that catalyzes the rate limiting step of tryptophan catabolism into N-formyl-kynurenine, has been shown to play critical role in the promotion of tolerance. IDO is expressed in certain cells and tissues, particularly in antigen presenting cells and the placenta. There is evidence that depletion of this essential amino acid increases susceptibility of T cells to apoptosis while some of its resulting metabolites (quinolinic acid and 3-hydroxyanthranilic acid) have a direct cytotoxic effect on effector T cells resulting in reduced immune activation. In addition, IDO-expressing cells preferentially induce proliferation
of regulatory T cells. This example demonstrates compositions and methods to exogenously deliver IDO in order to manipulate the ratio of tryptophan to kynurenines to direct localized metabolism in the context of inflammation, inflammatory diseases, and autoimmune diseases.
Galectin 3 (Gal3) is a chimera type member of the β-galactoside-binding soluble lectin family and is widely expressed in numerous cells. It has a strong affinity for proteins in the extracellular matrix (ECM) such as laminin, collagen, and vitronectin, as well as certain immune cell receptors including CD7, CD71, CD98, and CTLA4.
Generally, Recombinant human IDO was tested for activity, purity and endotoxin content using a spectrophotometric, SDS-PAGE, and ChromoLAL method, respectively. Murine bone-marrow derived dendritic cells (DCs) responses to extracellular IDO were evaluated by incorporating the enzyme into the media at 15 μg/mL. Expression of cell surface maturation markers (CD80/CD86/MHCII) was assessed by flow cytometry, IL-12p70 and IL-10 cytokine secretion by ELISA, and morphology changes and viability by microscopy. DCs were then pre-treated with ovalbumin 323-339 peptide (OVA) and incubated with OVA-specific CD4+ T cells, previously isolated from OT-II mice splenocytes using a magnetic negative selection process, either in the presence or absence of IDO and the enzyme inhibitor 1-methyl tryptophan (MT). Proliferation was measured using carboxyfluorescein succinimidyl ester (CFSE) dilution. Other materials and methods used are provided in greater detail herein.
Generally, the results demonstrated that IDO showed a specific activity of 400 pmoles/min/μg with over 90% purity and less than 1 EU/mL. CD80/CD86/MHCII evaluation revealed DCs remain immature in the presence of extracellular IDO and are able to resist maturation when challenged with lipopolysaccharide. Secretion of the proinflammatory cytokine IL-12p70 was significantly reduced in the presence of extracellular IDO. Additionally, IDO-treated DCs are able to suppress antigen-specific CD4+ T cell proliferation. This effect is mediated by active enzyme as demonstrated by the introduction of MT. Further, a fusion construct of Galectin 3 and NanoLuciferase does not alter the activity of either protein. Binding to laminin, collagen type 1, vitronectin, Jurkat T and dendritic cells by the fusion construct can be mediated by the carbohydrate recognition domain and was not observed to induce cell death. The Fusion construct does not act as a pathogen associated molecular pattern and is able to selectively bind primary splenocytes. Dendritic cells treated with IDO-Gal3 fusion proteins are able to maintain an immature phenotype and suppress antigen specific T cell proliferation. This suppression can be active enzyme dependent. In vivo delivery of the IDO-Gal3 fusion construct was able to modulate localized metabolism by suppressing gene expression of inflammatory cytokines and increasing kynurenines. Additional results are discussed below.
