Objective:To map the susceptibility allele of aberrant peripheral CD8 + T cell number in SLE model- (NZB×NZW) F1 mice. Methods:(NZB×NZW)F1×NZW backcross mice model was set up and polymorphic microsatellite markers and quantitative trait locus(QTL) analysis was used. Results:Susceptibility allele of aberrant CD8 + T cell number was linked to the microsatellite marker D1Mit36 (Lods>3) which is localized at 92 3 cM on the telomeric region of chromosome 1 The percentage of CD8 + T cells in the periphe...
