Direct cell-cell interactions between fibroblasts and other cell types

Effect

Reference


Macrophage

Direct transfer (of FITC-dextran, mannose BSA gold) from macrophages to fibroblasts

[62,63]

Neutrophil

Neutrophil adhesion to fibroblasts is increased by PMA treatment of neutrophils and by IL-1α

[64]

or TNF-α treatment of fibroblasts

Fibroblasts provide directional guidance to adhering neutrophils

[65]

PAF and IL-8 enhance neutrophil adhesion to and motility of adhered neutrophils along

[66]

fibroblasts, respectively, in an integrin β2 dependent process

Lymphocyte

Fibroblasts synthesize IL-1α, IL-1β, IL-6 and ICE

[67]

Fibroblast mediated synthesis of collagen type I and type III is decreased

[68]

Eosinophil

Activated eosinophils adhere to fibroblasts: this adhesion is inhibited with RGDS

[69]

Mast cell

Formation of mast pseudopods and their translocation to fibroblast surface

[70]

Mast cell stimulates fibroblast proliferation after cell-cell contact in an IL-4 dependent manner

[71]

Gap junctions between the mast cell and fibroblast are possible

[72]

Osteoblast-like cells

Osteoblast-like cells stimulate fibroblast proliferation (regulation of osteoprogenitor cell

[73]

proliferation?)


BSA, bovine serum albumen; ICE, interleukin-1β -converting enzyme; IL, interleukin; FITC, fluorescein isothiocyanate; PAF, platelet-activating factor; PMA, phorbol myristate acetate; RGDS, arginyl-glycyl-aspartyl-serine; TNF, tumor necrosis factor.
