Versican is an extracellular matrix (ECM) proteoglycan that interacts with cells
by binding to non-integrin and integrin receptors and to other ECM components
that associate with the cell surface. Recent studies have shown also that
versican interacts with myeloid and lymphoid cells promoting their adhesion and
production of inflammatory cytokines. Versican is produced by stromal cells, as
well as leukocytes, and is markedly increased in inflammation. Inflammatory
agonists, such as double-stranded RNA mimetics (e.g., poly I:C), stimulate
stromal cells, smooth muscle cells and fibroblasts, to produce fibrillar ECMs
enriched in versican and hyaluronan (HA) that interact with leukocytes promoting
their adhesion. Interference with the incorporation of versican into this ECM
blocks monocyte adhesion and dampens the inflammatory response. Tumor cells also
express elevated levels of versican which interact with myeloid cells to promote
an inflammatory response, through stimulating cytokine release, and metastasis.
In addition, myeloid cells, such as macrophages in tumors, synthesize versican
which affects tumor cell phenotypes, inflammation, and subsequent metastasis.
Versican, by binding to hyaluronan, influences T lymphocyte phenotypes and in
part controls the ability of these cells to synthesize and secrete cytokines that
influence the immune response. Collectively, these studies indicate that versican
as an ECM molecule plays a central role in inflammation and as a result it is
emerging as a potential target promising wide therapeutic benefits.
