Murine Interferon-gamma Inducible Protein-10 (IP-10) Secreted by Lactococcus Lactis Chemo-attracts Human CD3+ Lymphocytes

Chemokines are members of the super family of cytokines necessary for leukocyte recruitment in tissues and lymphoid organs. The interferon-gamma inducible protein-10 (IP-10) chemo-attracts CXCR3-expressing cells, such as activated T lymphocytes and monocytes. We have genetically engineered a strain of Lactococcus lactis to secrete a biologically active murine IP-10 that interacts with human CXCR3, its homolog receptor, and chemo-attracts human CD3+ T lymphocytes.
