Description:
Subsets of murine CD4+ T cells localize to different areas of the spleen after adoptive transfer. Naive and T helper 1 (TH1) cells, which express the chemokine receptor CCR7, are home to the periarteriolar lymphoid sheath, whereas activated TH2 cells, which lack CCR7, form rings at the periphery of the T cell zones near B cell follicles. Retroviral transduction of TH2 cells with CCR7 forces them to localize in a TH1-like pattern and inhibits their participation in B cell help in vivo but not in vitro. Thus, differential expression of chemokine receptors results in unique cellular migration patterns that are important for effective immune responses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Randolph, D A -- Huang, G -- Carruthers, C J -- Bromley, L E -- Chaplin, D D -- AI34580/AI/NIAID NIH HHS/ -- T32 GM07200/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1999 Dec 10;286(5447):2159-62.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Allergy and Immunology, Department of Internal Medicine, Center for Immunology, Washington University School of Medicine.
