Description:
T lymphocyte chemotactic factor (TCF) was purified to homogeneity from the conditioned media of phytohemagglutinin-stimulated human blood mononuclear leukocytes by a sequence of chromatography procedures. The amino-terminal amino acid sequence of the purified TCF showed identity with neutrophil-activating protein (NAP-1). Both TCF and recombinant NAP-1 (rNAP-1) were chemotactic for neutrophils and T lymphocytes in vitro supporting the identity of TCF with NAP-1. Injection of rNAP-1 into lymphatic drainage areas of lymph nodes in Fisher rats caused accelerated emigration of only lymphocytes in high endothelial venules. Intradermal injection of rNAP-1 caused dose-dependent accumulation of neutrophils and lymphocytes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Larsen, C G -- Anderson, A O -- Appella, E -- Oppenheim, J J -- Matsushima, K -- New York, N.Y. -- Science. 1989 Mar 17;243(4897):1464-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Immunoregulation, National Cancer Institute, Frederick, MD 21701.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2648569" target="_blank"〉PubMed〈/a〉
