The expression of periphery blood leucocyte CCR3 and CCR5 in the children with Epstein-Barr virus associated infectious mononucleosis / 中华实验和临床病毒学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To explore the expression of periphery blood leucocyte CCR3 and CCR5 and to comprehend T helper cell in the Children with Epstein-Barr virus associated infectious mononucleosis.</p><p><b>METHODS</b>We defined the children according to the diagnosis criterion through Paul-Bunnell test inspecting the children's periphery blood unusual lymphocyte and detecting their anti-EBV-CA-IgM, anti-EBV-CA-IgG and anti-EBV-NA-IgG by ELISA and counted the ratio of CCR3 + and CCR5 + cells in lymphocytes with flow cytometry.</p><p><b>RESULTS</b>The ratio of unusual lymphocyte in IM was higher than that of the healthy control group (P < 0.05). The ratio of CCR3 + cells in IM group was higher than that of the healthy control group (P < 0.05). The ratio of CCR5 + cells in IM group was significantly lower than that of the healthy control group. CCR3 + had direct interrelation with fever continued time and the ratio of unusual lymphocyte. There was a negative interrelation between CCR5 and fever continued time (P < 0.05).</p><p><b>CONCLUSIONS</b>Children infectious of IM expressed higher level of CCR3 + and lower level of CCR5 + and there was a tendency of Th2 polarization with over production of T helper cell divide imbalance. CCR3 + and CCR5 + may be important targets to judge the degree of seriousness of IM.</p>
