Analysis of Neutral Glycosphingolipids of Theileria sergenti Piroplasms

[摘要] References(23)Cited-By(2)Neutral glycosphingolipids (GSLs) were isolated from a lipid extract of Theileria sergenti piroplasms and analyzed by thin-layer chromatography (TLC) and liposome immune lysis assay (LILA); two predominant GSLs, designated as N-1 and N-2 were separated on TLC. N-1 GSL showed the same mobility as lactosylceramide (LacCer) on the TLC plate. On the other hand, the mobility of N-2 GSL on the TLC plate was identical to that of galactosylparagloboside. In order to characterize the molecular species of neutral GSLs from T.sergenti, N-1 and N-2 GSLs were tested by LILA with antibodies against LacCer and galactosylparagloboside, respectively. N-1 GSL had reactivity to anti-LacCer antibody and N-2 reacted with the antibody to galactosylparagloboside. These results suggest that N-1 and N-2 GSLs are LacCer (Galβ1-4Glcβ1-1Cer) and galactosylparagloboside (Galα1-3Galβ1-4GlcNAcβ1-3Galβ1-4Glcβ1-1Cer), respectively.
