• at 6 to 8 weeks of age, mice show no differences in the ratio of naive T cells relative to control-mice
• in response to CCL21 exposure, the displacement and velocity of primary T cells during migration on ICAM-1 are reduced to 43% and 58% of those in control T cells, respectively
• in transwell migration assays, the numbers of T cells that migrate to the lower chambers containing CCL21 are markedly lower than those of control T cells; the numbers of T cells that migrate through ICAM-1-coated filters is not reduced relative to the number of T cells that migrate through uncoated filters, unlike in control cells
• in response to CCL21 exposure, primary T cells show a significant reduction in the shear stressresistant adhesion to ICAM-1 relative to control T cells
• analysis of the homing capability of adoptively transferred T cells showed that the extent of T cell trafficking into the spleen and peripheral lymph nodes is reduced to ~50% and 30%, respectively, of that in control cells
• spleen and peripheral lymph nodes show significantly lower numbers of T cells and B cells than control lymphoid tissues due to impaired lymphocyte trafficking
• however, numbers of T cells and B cells are normal in blood
• spleen is significantly smaller than in control mice
• upon stimulation with chemokine CCL21, Mst1 does not translocate to the leading edge but remains diffusely distributed in the cytoplasm of primary T cells, unlike in control T cells
• most CCL21-stimulated T cells show impaired redistribution of LFA-1, whereas ~30% of CCL21-treated control T cells display polarized morphologies with a leading edge and uropod, to which LFA-1 and CD44 are clustered, respectively
• however, the abundance of CCR7 (the receptor for CCL21) in T cells is similar to that in control T cells
• inguinal lymph nodes are significantly smaller than in control mice
• spleen and peripheral lymph nodes show significantly lower numbers of T cells and B cells than control lymphoid tissues
