L-selectin (CD62L) is normally highly expressed in naïve T cells. The expression
levels of CD62L have been reported to be decreased on T cells during the
inflammatory state. It is currently unknown whether the frequency of CD62L(+) T
cell subsets in the peripheral blood can be used as a marker to indicate is
disease severity during inflammation. Our study evaluated whether circulating
CD62L(+) T cell subsets correlate with the severity of disease by testing an
autoimmune condition of scurfy (sf) mouse associated with multi-organ
inflammation due to regulatory T cell deficiency. We observed that scurfy mice
spontaneously developed an inflammatory phenotype with a significant decrease in
the percentage of CD62L-expressing CD4(+) T and CD8(+) T cells in the peripheral
blood. The percentage of CD62L(+)CD4(+) T and CD62L(+)CD8(+) T cells negatively
correlated with disease severity, as determined by the weight of spleen and
liver, as well as the mean area of lymphocyte infiltrates in lung and liver. The
percentage of CD8(+) T cells also correlated directly with these markers of
disease severity. To conclude, our results support the concept that circulating
CD62L-expressing T cells may be used as markers of disease severity in sf mice
which is equivalent to a syndrome characterized by immune dysregulation with
polyendocrinopathy, enteropathy, and X-linked inheritance (IPEX syndrome) in
humans, or in other autoimmune or inflammatory conditions.
