Ba.kgrounds: Recent a.va.ces in post Kidney Tra.spla.ta.ion (KT) ca.e, ha.e led to a.dra.0}tic im.rovem.nt in short-term.outcom.s in order to a.hieve tra.spla.ta.ion tolera.ce;including the idea. tool for clinica. m.nitoring & new thera.eutic line. This study wa. underta.en to a.a.yze the CD62L in Kidney Tra.spla.t Recipients (KTRs) a.d to investiga.e its effica.y a. a.m.rker of good gra.t surviva.. m.thods: Fifty pedia.ric KTRs a.d 12 hea.thy controls were included in the study, the frequency of T cell a.tiva.ion m.rkers;CD62L wa. m.a.ured with flow cytom.try a.ter rena. tra.spla.ta.ion. Clinica., la.ora.ory, im.unosuppressive thera.y da.a.a.d gra.t function of tra.spla.t recipients were collected a.d correla.ed with their CD62L periphera. blood percenta.e. Results: The circula.ing CD62L% wa. significa.tly m.re in tra.spla.t recipients tha. controls (44.74% ± 17.45% vs. 33.36% ± 11.54%, p = 0.02).
