    ..In conclusion, the high fraction of circulating IgA+ and IgG+ B cells expressing CCR9 and CCR10 in the first months of life indicates activation of naïve B cells in the gut, coinciding with bacterial colonization. ..

    ..Disruption of the hydrophobic contacts also induced the active conformation of ?4 ?7 . Thus, the findings obtained in the present study reveal an important structural basis for the low-affinity state of integrin. ..

    ..These findings establish that Peyer's patch dendritic cells imprint gut-homing specificity on T cells, and thus license effector/memory cells to access anatomical sites most likely to contain their cognate antigen. ..
