Epstein-Barr virus induced gene 3, also known as interleukin-27 subunit beta or IL-27B, is a protein which in humans is encoded by the EBI3 gene. [5] [6]
This gene was identified by the induction of its expression in B lymphocytes by Epstein–Barr virus infection. The protein encoded by this gene is a secreted glycoprotein, which is a member of the hematopoietin receptor family related to the p40 subunit of interleukin 12 (IL-12). It plays a role in regulating cell-mediated immune responses. [7]
EBI3 is a subunit in 2 distinct heterodimeric cytokines: interleukin-27 (IL27) and IL35. IL27 is composed of p28 (IL27) and EBI3. IL27 can trigger signaling in T cells, B cells, and myeloid cells. [8] IL35, an inhibitory cytokine involved in regulatory T-cell function, is composed of EBI3 and the p35 subunit of IL12. [7] [9]
Interleukin-23 subunit alpha is a protein that in humans is encoded by the IL23A gene. IL-23 is produced by dendritic cells and macrophages.
Interleukin 30 (IL-30) forms one chain of the heterodimeric cytokine called interleukin 27 (IL-27), thus it is also called IL27-p28. IL-27 is composed of α chain p28 and β chain Epstain-Barr induce gene-3 (EBI3). The p28 subunit, or IL-30, has an important role as a part of IL-27, but it can be secreted as a separate monomer and has its own functions in the absence of EBI3. The discovery of IL-30 as individual cytokine is relatively new and thus its role in the modulation of the immune response is not fully understood.
Interleukin 27 (IL-27) is a member of the IL-12 cytokine family. It is a heterodimeric cytokine that is encoded by two distinct genes, Epstein-Barr virus-induced gene 3 (EBI3) and IL-27p28. IL-27 is expressed by antigen presenting cells and interacts with a specific cell-surface receptor complex known as IL-27 receptor (IL-27R). This receptor consists of two proteins, IL-27ɑ and gp130. IL-27 induces differentiation of the diverse populations of T cells in the immune system and also upregulates IL-10.
Interleukin-26 (IL-26) is a protein that in humans is encoded by the IL26 gene.
Interleukin 24 (IL-24) is a protein in the interleukin family, a type of cytokine signaling molecule in the immune system. In humans, this protein is encoded by the IL24 gene.
Interleukin-22 (IL-22) is protein that in humans is encoded by the IL22 gene.
Subunit beta of interleukin 12 is a protein that in humans is encoded by the IL12B gene. IL-12B is a common subunit of interleukin 12 and Interleukin 23.
Interleukin-12 subunit alpha is a protein that in humans is encoded by the IL12A gene.
Interleukin 35 (IL-35) is a recently discovered anti-inflammatory cytokine from the IL-12 family. Member of IL-12 family - IL-35 is produced by wide range of regulatory lymphocytes and plays a role in immune suppression. IL-35 can block the development of Th1 and Th17 cells by limiting early T cell proliferation.
Interleukin-12 receptor, beta 1, or IL-12Rβ1 in short, is a subunit of the interleukin 12 receptor. IL12RB1, is the name of its human gene. IL-12Rβ1 is also known as CD212.
Interleukin 10 receptor, beta subunit is a subunit for the interleukin-10 receptor. IL10RB is its human gene.
Interleukin 21 receptor is a type I cytokine receptor. IL21R is its human gene.
Interleukin 20 receptor, alpha subunit is a subunit for the interleukin-20 receptor. IL20RA is its human gene.
Interferon alpha-7 is a protein that in humans is encoded by the IFNA7 gene.
Interleukin-31 receptor A is a protein that in humans is encoded by the IL31RA gene.
Interleukin 18 receptor accessory protein, also known as IL18RAP and CDw218b, is a human gene.
Interleukin 27 receptor, alpha is a subunit of the interleukin-27 receptor. IL27RA is its human gene.
Interleukin 3 receptor, alpha (IL3RA), also known as CD123, is a human gene.
Interferon alpha-16, also known as IFN-alpha-16, is a protein that in humans is encoded by theIFNA16 gene.
Interferon lambda 3 encodes the IFNL3 protein. IFNL3 was formerly named IL28B, but the Human Genome Organization Gene Nomenclature Committee renamed this gene in 2013 while assigning a name to the then newly discovered IFNL4 gene. Together with IFNL1 and IFNL2, these genes lie in a cluster on chromosomal region 19q13. IFNL3 shares ~96% amino-acid identity with IFNL2, ~80% identity with IFNL1 and ~30% identity with IFNL4.
