Detection of IL‑6 in J774A.1 Mouse Cell Line by Flow Cytometry. LPS stimulated J774A.1 mouse reticulum cell sarcoma macrophage cell line was stained with Rat Anti-Mouse IL‑6 PE‑conjugated Monoclonal Antibody (Catalog # IC406P, filled histogram) or isotype control antibody (Catalog # IC005P, open histogram). To facilitate intracellular staining, cells were fixed with Flow Cytometry Fixation Buffer (Catalog # FC004) and permeabilized with Flow Cytometry Permeabilization/Wash Buffer I (Catalog # FC005).

IL-6 (Interleukin-6), also known as Interferon beta 2, is a secreted,
24-30 kDa member of the IL-6 family of proteins. In mouse, mature IL-6 is a highly
glycosylated, monomeric polypeptide that is 187 amino acids (aa) in length, and
shares 85% and 40% aa identity with rat and human IL-6, respectively. IL-6 expression is induced in a highly diverse
group of cells including vascular and visceral smooth muscle cells, T helper
cells, fibroblasts, astrocytes, endothelial cells, neurons, monocytes,
microglia, pancreatic islet alpha -cells, osteoblasts, keratinocytes and white
adipocytes. The receptor for IL-6 is
composed of two distinct type I transmembrane glycoproteins, an 80-85 kDa
ligand-binding IL-6R alpha subunit, and two signal-transducing 130-135 kDa gp130
subunits. Notably, the IL-6 system seems
to exist as one of two states; there is a "classic signaling" state where IL-6
interacts with the transmembrane forms of both IL-6R alpha and gp130 in a signaling complex,
and an IL-6 "trans-signaling" state, where IL-6 is bound to soluble IL-6R alpha in a
circulating complex that subsequently interacts with transmembrane gp130. The "classic signaling" complex occurs on
select cells such as hepatocytes, neutrophils and monocytes. The outcome of "classic signaling" is typically
anti-inflammatory, promoting hepatocyte and pancreatic proliferation and
regeneration, plus hepatic acute phase protein production. "Trans-signaling",
by contrast, is very widespread, as a soluble IL-6R alpha :IL-6 complex can go almost
everywhere and interact with the ubiquitously-expressed gp130. Relative to "classic signaling" however, this
type of signaling is typically pro-inflammatory, and results in endothelial and
smooth muscle cell activation, an inhibition of Treg differentiation, and a
mononuclear cell infiltration into inflammatory environments.
