Biological aspects of monocyte chemoattractant protein-1 (MCP-1).
In this communication, we have asked if MCP-1 is the mediator of cellular infiltration in DCH, outlining the criteria in Table 3. Preliminary data suggest that PHA-stimulated lymphocytes secrete MCP-1, and that MCP-1 can be produced in response to antigen stimulation. MCP-1 attracts monocytes and basophils, but not neutrophils. The question of a lymphocyte response to MCP-1 requires further study. We have emphasized that the discovery of leukocyte-specific NAP-1 and MCP-1 should now be followed by exploration of conditions in which one agonist is secreted without the other. This would be expected, for example, in DCH, which is characterized by mononuclear leukocyte infiltration without neutrophils.
