Intercellular adhesion molecule-1 (ICAM-1) and lymphocyte function-asociated antigen-1 (LFA-1) are cell surface adhesion receptors that bind to one another and promote a variety of effector/target cell interactions in tissues affected by inflammatory or immune processes.

As determined by immunocytochemistry and immunoprecipitation using a monoclonal anti-ICAM-1 antibody, interleukin-1-alpha (IL-1a), tumour necrosis factor-alpha (TNFa) and interferon-gamma (IFNg) strongly enhanced surface expression of ICAM-1 in both GO- and normal OF.

No effect was observed in either cell type with interleukin-2, transforming growth factor-beta, or IgGs from patients with HT, RA and normal individuals.

Using phorbol ester-activated, 51Cr-labelled peripheral blood mononuclear cells (PBMCs) in a cell adhesion assay, we demonstrated potent adhesive activity of ICAM-1 in GO-OF pretreated with IL-1a, TNFa, IFNg or Graves' IgGs, while all other compounds did not affect PBMC adhesion to GO-OF.

Human melanocyte expression of intercellular adhesion molecule-1 (ICAM-1) with or without stimulation by interferon gamma (IFN-G), tumor necrosis factor alpha (TNF-alpha), or interleukin-1-alpha (IL-1 alpha), was measured utilizing direct immunofluorescence and fluorescence-activated cell sorting (FACS).

|
Melanocytes grown in vitro expressed low levels of ICAM-1, which could be increased by exposing the cells to IFN-G, TNF-alpha, or IL-1 alpha.
|

|
The lowest dose necessary to cause a significant increase in melanocyte ICAM-1 expression was 1 U/ml IFN-G, 0.3 ng/ml TNF-alpha, or 3 U/ml IL-1 alpha.

|
Melanocytes were most sensitive to TNF-alpha stimulation, with the greatest levels of ICAM-1 expression following 30 ng/ml or more TNF-alpha.

|
When IFN-G was added to melanocyte cultures in combination with TNF-alpha or IL-1 alpha, there was an additive increase in ICAM-1 expression but no synergy was noted with the combined cytokines.

To our knowledge, this is the first report of melanocyte ICAM-1 induction by TNF-alpha and IL-1 alpha and by physiologically relevant doses of IFN-G.
