Description: Oncostatin M is a cytokine that is produced by macrophages, dendritic cells, and T lymphocytes during inflammatory events. The Type-I and Type-II Oncostatin M receptors are located on the cell surface of endothelial and tumor cells, contain the glycoprotein 130 (gp130) subunit, and activate the JAK/STAT signaling pathway.

Description: <p>Interleukin 15 (IL-15) is a widely expressed proinflammatory cytokine that is structurally and functionally related to interleukin 2 (IL-2). IL-15 signals through JAK kinases to activate STAT3, STAT5, and STAT6 transcription factors. IL-15 regulates the activation of T cells, neutrophils, and macrophages, and is a stimulatory cytokine promoting dendritic cell function. IL-15 expression is dysregulated in chronic inflammatory disorders, including rheumatoid arthritis, psoriasis, and pulmonary inflammatory diseases. Therefore, IL-15 may serve as an effective therapeutic target, due to the beneficial outcomes of IL-15 neutralization in models of psoriasis and diabetes. Human IL-15 shows activity on mouse cells.</p>

Description: <p>Stem cell factor (SCF) is a cytokine made by fibroblasts and endothelial cells. SCF binds to the receptor c-Kit/CD117 and plays a critical role in the maintenance, survival, and differentiation of hematopoietic stem cells. While human SCF shows no activity on murine cells, murine and rat SCF are active on human cells.</p>

Description: Interleukin 2 (IL-2) is an immunomodulatory cytokine that is produced by lymphocytes. IL-2 signals through the IL-2R receptor to induce activated T cell proliferation and promote T cell differentiation. IL-2 also stimulates the proliferation and differentiation of B cells, natural killer cells, monocytes, and macrophages.

Description: <p>Interleukin 12 (IL-12) is an inducer of cell-mediated immunity and is produced by dendritic cells, macrophages, and B cells after antigen stimulation. IL-12 functions to promote naïve T cell differentiation into the type 1 T helper cell (Th1) lineage. IL-12 also stimulates the production of interferon gamma (IFN-γ) and tumor necrosis factor alpha (TNF-α) from T cells and natural killer cells. Mouse IL-12 is active on human and mouse cells.</p>

Description: <p>Interleukin 11 (IL-11) is a member of the gp130 family of cytokines. IL-11 functions to promote hematopoietic stem cell proliferation and megakaryocyte differentiation. In non-hematopoietic cell populations, IL-11 stimulates acute-phase proteins, modulates the development of immunoglobulin-producing B cells, and regulates bone turnover. IL-11 binds the IL-11Rα receptor to activate JAK downstream signaling. Human IL-11 shows activity on murine cells.</p>

Description: Interleukin 36 gamma (IL-36 ɣ) is a member of the interleukin 1 (IL-1) cytokine family and protects against pathogens in the skin, lung, and stomach epithelial barriers. IL-36 ɣ binds the interleukin-1 receptor accessory protein (IL-1RAcP) and the orphan IL-1R-related protein 2 (IL-1Rrp2) receptors to activate NF-kB and MAP kinase signaling pathways, resulting in the induced production of inflammatory cytokines and chemokines.

Description: Fms-related tyrosine kinase 3 ligand (FLT-3 ligand) is a growth factor that regulates hematopoietic cell proliferation. FLT-3 ligand signaling is transmitted through the fms-related tyrosine kinase 3 (FLT-3) receptor. FLT-3 ligand promotes the long-term expansion and differentiation of pro-B cells in the presence of interleukin 7 (IL-7) or in combination of IL-7 and interleukin 3 (IL-3).

Description: <p>Resistin-like molecule-alpha (RELM-α) is a member of the RELM family of secreted proteins containing conserved C-terminus cysteines. The RELM family consists of Resistin (FIZZ3), RELM-α (FIZZ1), RELM-β (FIZZ2), and RELM-γ (FIZZ4). RELM-α and Resistin are secreted by adipocytes, unlike RELM-β which is secreted by gastrointestinal epithelial cells, and RELM-γ which is expressed by peripheal blood granulocytes and bone marrow cells.</p>

Description: Resistin-like molecule-gamma (RELM-γ) is a member of the RELM family of secreted proteins containing C-terminal cysteines. The RELM family consists of Resistin (FIZZ3), RELM-α (FIZZ1), RELM-β (FIZZ2), and RELM-γ (FIZZ4). RELM-γ is secreted by peripheral blood granulocytes, bone marrow, spleen, intestine, and lung. RELM-γ functions to promote and regulate promyelocytic differentiation, in addition to regulating nutrient-associated insulin sensitivity in the intestinal tract. Rodents secrete all four RELM family members, whereas Resistin and RELM-β are the only RELM family members found in humans.

Description: Epstein-Barr virus induced gene-3 (EBI3) is a secreted glycoprotein belonging to the hematopoietin receptor family related to the p40 subunit of interleukin 12 (IL-12). EBI3 expression is induced in B-lymphocytes in response to Epstein-Barr virus infection. EBI3 forms heterodimers with p28 to form interleukin 27 (IL-27), and with p35 to form interleukin 35 (IL-35). Both IL-27 and IL-35 have anti-inflammatory and regulatory activity.

Description: <p>The globular subunit of adipocyte complement-related protein of 30 kDa (ACRP-30) is a naturally occurring cleavage product of adiponectin, a protein made exclusively by adipocytes. ACRP-30 is an abundant serum protein and plays an important role in hyperglycemia, insulin resistance, and fatty acid oxidation. ACRP-30 signals through adiponectin receptor 1 (AdipoR1) and adiponectin receptor 2 (AdipoR2).</p>

Description: Heparin-binding EGF-like growth factor (HB-EGF) is a member of the epidermal growth factor (EGF) family and is expressed by monocytes and macrophages. HB-EGF is the predominant growth factor involved in epithelialization during wound healing. HB-EGF signals through the receptor tyrosine kinase ErbB2 to maintain adult heart homeostasis, and promotes cardiac valve development through binding in high affinity to the epidermal growth factor receptor (EGFR). HB-EGF binds the the ErbB4 receptor tyrosine kinase to mediate implantation of the human blastocyst. HB-EGF also functions as a potent mitogen for fibroblasts and smooth muscle cells.

Description: <p>Endocrine gland-derived vascular endothelial growth factor (EG-VEGF) is an angiogenic growth factor that is expressed in the ovaries, testis, adrenal, and placental tissues. EG-VEGF has mitogenic, chemoattractive, and antiapoptotic functional roles. EG-VEGF signaling is mediated through binding the G protein-coupled receptors prokineticin receptor 1 (PKR1) and prokineticin receptor 2 (PKR2). Polycystic ovaries display strong EG-VEGF expression that is associated with increased angiogenesis and cyst formation, which could lead to the formation of polycystic ovary syndrome and infertility.</p>
