Long-term superior cervical sympathectomy induces mast cell hyperplasia and increases histamine and serotonin content in the rat dura mater.
Neuroscience. 2000;96(1):205-13.
Mast cell hyperplasia is found in different pathologies such as chronic inflammatory
processes, fibrotic disorders, wound healing or neoplastic tissue transformation. The
functional significance of the accumulation of mast cells in these processes is largely
unknown. It is now established that bone marrow-derived mast cell progenitors
circulate in peripheral blood and subsequently migrate into the tissue where they
undergo final maturation under the influence of local microenvironmental factors.
Cytokines are of particular importance for mast cell recruitment, development, and
function. Stem cell factor (SCF) is a unique mast cell growth factor, since mast cells
disappear completely in the absence of SCF. However, several other cytokines such
as IL-3 and IL-4 have been shown to influence mast cell proliferation and function
also. This review focuses on the role of cytokines in the regulation of mast cell
hyperplasia.
