Transgenic Mice in which the Gene for MCP-1 is Deleted

Posted Jun 15 2010 5:00pm

Description of Invention:
Dr. Yoshimura has developed a transgenic mouse which does not express the chemokine MCP-1 due to a deletion of the gene for MCP-1. MCP-1 is a CC chemokine which is responsible for recruiting monocytes into sites of inflammation and cancer. Using a thioglycollate challenge as a measure of the impact of the deletion of MCP-1, MCP-1 deficient mice exhibit a 60% reduction in the number of monocytes/macrophages at 96 hours compared to wild type mice. Unlike previously generated MCP-1 deficient mice in which the expression of the neighboring gene for MCP-3 is down-regulated (our own data), the expression of MCP-3 is up-regulated in this mouse model.

This mouse may be useful as an in vivo model for evaluating the role of MCP-1 and MCP-3 in cancer or other diseases associated with inflammation due to the accumulation of monocytes.
