Interleukin 6 (IL6, also referred to as IFNB2, IFN-beta-2, BSF2, BSF-2, IL-6, HSF, HGF and CDF) is found on the chromosome 7p15.3

Interleukin 6 is conserved in Rhesus monkeys, chimpanzees, chickens, rats, mice and dogs. The gene creates a 23718 Da protein made up of a total of 212 amino acids.

As a multifunctional α-helical cytokine, IL6 mediates the growth and differentiation of cells in numerous tissues, which is specifically known for its role in acute phase reactions and the immune response. IL6 plays a crucial role in guiding the change from innate to acquired immunity.

IL-6 Background

As a multifunctional α-helical cytokine, Interleukin-6 (IL-6) controls the growth and differentiation of cells in numerous tissues. It is specifically known for its role in acute phase reactions and the immune response.

The IL-6 protein is produced by different types of cells, such as macrophages and T cells as a phosphorylated and unevenly glycosylated molecule. It applies actions via its heterodimeric receptor made up of IL-6R that does not contain the tyrosine/kinase domain and attaches IL-6 with low affinity.

The glycoprotein 130 (gp130) is universally expressed and attaches the IL-6. IL-6R complex has excellent affinity and thus transduces signals.

IL-6 plays a key role in bone metabolism, hematopoiesis, and cancer development, and has been defined as a crucial factor in guiding the change from innate to acquired immunity.
