    Techniques Used:

    (A, B) The percentages of S1P1-positive PBMCs after the treatment with different concentrations of AD2900, FTY720, or SEW2871 and at different time points were examined by FACS analysis. S1P1 expression was tested in PBMCs after a 30-min treatment with AD2900 at different concentrations (A) or after a 30-min or 60-min treatment with 100 nM AD2900, FTY720, or SEW2871 (B) . (C) The percentage of CCR7-positive PBMCs was tested by FACS analysis after a 30-min treatment with 100 nM AD2900, FTY720, or SEW2871. All the significances are compared to untreated PBMCs. Results summarize the results of at least four independent experiments. Results of Student’s t -test: *(P < 0.05, two-tailed test), ** (P < 0.01, two-tailed test), *** (P < 0.001, two-tailed test), **** (P < 0.0001, two-tailed test).

    C57BL/6 mice were orally administered with 1.8, 2.7, and 3.6 mg/l AD2900 or 1.8 mg/l FTY720 for 2 days, as shown in Figure . Leukocytes from blood, spleen, and pLNs were collected and stained with CD3e and S1P1 or CCR7 fluorescent antibodies and then analyzed by FACS analysis. The percentages of S1P1+ CD3e+ T cells from blood (A) , spleen (B) , and pLNs (C) are shown. The percentages of CCR7+ CD3e+ T cells from blood (D) , spleen (E) , and pLNs (F) are shown. All the significances are compared to untreated healthy mice. Results summarize at least three independent experiments.

    Techniques Used: Staining, Two Tailed Test

    As an antagonist to S1P receptors 1–5, AD2900 can compete with S1P to bind S1P receptors leading to reduced S1P signaling and enhanced expression of S1P1 on T cells in S1P-rich environments such as the blood and the spleen. This altered expression, together with decreased CCR7 expression, inhibits T-cell entry into the lymph nodes (LNs) from the blood, causing accumulation of T cells in the blood. However, the entry of T cells to the spleen is not affected because it is not S1P dependent. Since Tcm-like cells express CCR7, these cells are attracted to the spleen and accumulate in it; yet, S1P1 elevated expression may have an effect on the S1P-dependent ingression of these cells from the MZ to the white pulp. Tef/em-like cells, which are CCR7 negative, are the primary T-cell subpopulation in the blood after AD2900 treatment. The significant decrease in naive T-cell counts in the circulation and peripheral lymphoid tissues tested may be explained by the inhibition of S1P signaling in the thymus leading to attenuated T-cell egression from the thymus to the circulation. Arrow key: thick = response; dashed = inhibition.
