Receptors for the Fc region of IgG (Fc gamma R) are members of the Ig superfamily that function in the activation or inhibition of immune responses. Human Fc gamma Rs are divided into three classes designated Fc gamma RI (CD64), Fc gamma RII (CD32), and Fc gamma RIII (CD16), which generate multiple isoforms, are recognized. The activating­ type receptor either has or associates non­covalently with an accessory subunit that has an immunoreceptor tyrosine­based activation motif (ITAM) in its cytoplasmic domain. Fc gamma RI binds IgG with high affinity and functions during early immune responses, whereas Fc gamma RII and RIII are low affinity receptors that recognize IgG as aggregates surrounding multivalent antigens during late immune responses. Three genes for human Fc gamma RII (A, B, and C) and one for mouse (Fc gamma RIIB), encoding type I transmembrane proteins with ITAM motifs (Fc gamma RII A and C) or ITIM motifs (Fc gamma RIIB) in their cytoplasmic domains, have been identified. Human CD32, also known as Low affinity immunoglobulin gamma Fc region receptor II-a (IgG Fc receptor II-a), Fc gamma RII A or FCGR2A Protein, is expressed on cells of both myeloid and lymphoid lineages as well as on cells of non-hematopoietic origin. Associated with an ITAM-bearing adapter subunit, FcR gamma , CD32a (Fc gamma RII A) delivers an activating signal upon ligand binding, and results in the initiation of inflammatory responses including cytolysis, phagocytosis, degranulation, and cytokine production. The responses can be modulated by signals from the co-expressed inhibitory receptors such as Fc gamma RII B, and the strength of the signal is dependent on the ratio of expression of the activating and inhibitory receptors.

Interleukin-20 (IL-20) is a member of the IL-10 family of regulatory cytokines that includes IL-10, IL-19, IL-20, IL-22, IL-24 and IL-26. Members of this family share partial homology in their amino acid sequences but they are dissimilar in their biological functions. IL-20 exhibits approximately 28% amino acid identity with IL-10 and 76% amino acid identity with mouse IL-20. There are two heterodimeric receptor complexes for IL-20. The first is composed of IL-20 R alpha and IL-20 R beta . The second is composed of IL-22 R and IL-20 R beta . Whereas the IL-22 R/IL-20 R beta complex is shared with IL-24, the IL-20 R alpha/IL-20 R beta complex is shared with both IL-19 and IL-24. IL-20 has been shown to initiate transduction cascades involving STAT3 and stimulates the induction of pro-inflammatory genes including TNF- alpha and MCP-1. Initial functional studies using transgenic mice suggest that IL-20 has the ability to regulate skin development. The over-expression of both human and mouse forms of IL-20 results in keratinocyte hyper-proliferation, abnormal epidermal differentiation, and neonatal lethality. In humans, IL-20 and its receptors are up-regulated in psoriatic skin, and polymorphisms in the IL-20 gene have been associated with plaque-type psoriasis. IL-20 may also have a role in hematopoiesis. It enhances the proliferation of multi-potential progenitors in vitro and increases their numbers and cell cycling status in IL-20 transgenic mice. IL-20 is also shown to suppress COX-2 and PGE2 and acts as an inhibitor of angiogenesis in model systems.

The Galectin family of proteins, with specificity for Nacetyllactosaminecontaining glycoproteins, consists of beta-galactoside binding lectins containing homologous carbohydrate recognition domains (CRDs). At least 14 mammalian galectins family members, which share structural similarities in their carbohydrate recognition domains (CRD), have been identified to date. Unlike the selectin family of proteins, the carbohydrate binding specificity of galectins is calcium-independent. A common function of galectins is to cross-link structures containing N-acetyl-lactosamine located at the cell surface and within the extracellular matrix. They also possess hemagglutination activity, which is attributable to their bivalent carbohydrate binding properties. Galectins are active both intracellularly and extracellularly. Although they are localized primarily in the cytoplasm and lack a classical signal peptide, galectins can also be secreted by one or more unidentified, non-classical, secretory pathways. They have diverse effects on many cellular functions including adhesion, migration, polarity, chemotaxis, proliferation, apoptosis, and differentiation. Galectins may therefore play a key role in many pathological states, including autoimmune diseases, allergic reactions, inflammation, tumor cell metastasis, atherosclerosis, and diabetic complications. The galectins have been classified into the prototype galectins(1, 2, 5, 7, 10, 11, 13, 14), which contain one CRD and exist either as a monomer or a noncovalent homodimer. The chimera galectins(Galectin3) containing one CRD linked to a nonlectin domain, and the tandemrepeat Galectins(4, 6, 8, 9, 12) consisting of two CRDs joined by a linker peptide.Galectins lack a classical signal peptide and can be localized to the cytosolic compartments where they have intracellular functions. However, via one or more as yet unidentified nonclassical secretory pathways, galectins can also be secreted to function extracellularly. Individual members of the galectin family have different tissue distribution profiles and exhibit subtle differences in their carbohydrate-binding specificities. Each family member may preferentially bind to a unique subset of cell surface glycoproteins.
