IL-12 alpha
Interleukin-12 subunit alpha (IL-12A; IL-12p35), an immune-suppressive cytokine, encodes a subunit of the cytokine IL-12 that acts on T and natural killer cells, and has a broad array of biological activities. IL-12A is a disulfide-linked heterodimer composed of the 35-kD subunit encoded by this gene, and a 40-kD subunit that is a member of the cytokine receptor family. IL-12 is primarily produced by professional antigen-presenting cells (APCs) such as B-cells and dendritic cells (DCs) as well as macrophages and granulocytes, induces the production of IFN-gamma, favors the differentiation of Th1 cells and is an important link between innate resistance and adaptive immunity[1][2].
IL-12A suppresses lymphocyte proliferation, induces expansion of IL-10-expressing and IL-35-expressing B cells and ameliorates autoimmune uveitis in mice by antagonizing pathogenic Th17 responses. IL-12A-mediated expansion of Treg and Breg cells and its amelioration of experimental autoimmune encephalomyelitis (EAE) correlated with inhibition of cytokine-induced activation of STAT1/STAT3 pathways. IL-12A may be utilized for in vivo expansion of Tregs and Bregs cells and autologous Tregs and Bregs cell immunotherapy[1][2].

The EpCAM/TROP1 protein serves as an important homogeneous interacting molecule that promotes direct contact between intestinal epithelial cells (IEC) and intraepithelial lymphocytes (IEL) in the mucosal epithelium. This feature helps establish an immune barrier against mucosal infections. EpCAM/TROP1 Protein, Human (His-SUMO) is the recombinant human-derived EpCAM/TROP1 protein, expressed by E. coli , with N-6*His, N-SUMO labeled tag.
