Popis: | Although a great deal is known about T cell entry into lymph nodes, much less is understood about how T lymphocytes access the splenic white pulp (WP). We show in this study that, as recently described for lymph nodes, fibroblastic reticular cells (FRCs) form a network in the T cell zone (periarteriolar lymphoid sheath, PALS) of the WP on which T lymphocytes migrate. This network connects the PALS to the marginal zone (MZ), which is the initial site of lymphocyte entry from the blood. T cells do not enter the WP at random locations but instead traffic to that site using the FRC-rich MZ bridging channels (MZBCs). These data reveal that FRCs form a substrate for T cells in the spleen, guiding these lymphocytes from their site of entry in the MZ into the PALS, within which they continue to move on the same network. |
