Description:
Unique among known human herpesviruses, Kaposi's sarcoma-associated herpesvirus (KSHV or HHV-8) encodes chemokine-like proteins (vMIP-I and vMIP-II). vMIP-II was shown to block infection of human immunodeficiency virus-type 1 (HIV-1) on a CD4-positive cell line expressing CCR3 and to a lesser extent on one expressing CCR5, whereas both vMIP-I and vMIP-II partially inhibited HIV infection of peripheral blood mononuclear cells. Like eotaxin, vMIP-II activated and chemoattracted human eosinophils by way of CCR3. vMIP-I and vMIP-II, but not cellular MIP-1alpha or RANTES, were highly angiogenic in the chorioallantoic assay, suggesting a possible pathogenic role in Kaposi's sarcoma.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Boshoff, C -- Endo, Y -- Collins, P D -- Takeuchi, Y -- Reeves, J D -- Schweickart, V L -- Siani, M A -- Sasaki, T -- Williams, T J -- Gray, P W -- Moore, P S -- Chang, Y -- Weiss, R A -- CA 67391/CA/NCI NIH HHS/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 1997 Oct 10;278(5336):290-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Cancer Research, Chester Beatty Laboratories, London SW3 6JB, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9323208" target="_blank"〉PubMed〈/a〉
