Ephrin B1–mediated repulsion and signaling control germinal center T cell territoriality and function

<jats:title>Guiding immune cells to the center</jats:title> <jats:p> Germinal centers (GCs) are the site of antibody affinity maturation. The GC response fundamentally depends on contact-dependent signal exchange between antigen-specific T and B lymphocytes. Lu <jats:italic>et al.</jats:italic> uncovered a repulsive guidance system that inhibits GC recruitment and retention of T follicular helper (T <jats:sub>FH</jats:sub> ) cells while simultaneously promoting their helper activities locally (see the Perspective by Moschovakis and Forster). This system comprises the GC-specific transmembrane ephrin B1 (EFNB1) molecule and two EFNB1 receptors—EPHB4 and EPHB6—expressed by activated T cells, including T <jats:sub>FH</jats:sub> cells. In the absence of EFNB1 on GC B cells or when EPHB6 was suppressed on T cells, inappropriately large numbers of T cells were recruited to and retained in the GC as a result of relaxed repulsion of T <jats:sub>FH</jats:sub> cells. </jats:p> <jats:p> <jats:italic>Science</jats:italic> , this issue p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6339" page="eaai9264" related-article-type="in-this-issue" vol="356" xlink:href="10.1126/science.aai9264">eaai9264</jats:related-article> ; see also p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6339" page="703" related-article-type="in-this-issue" vol="356" xlink:href="10.1126/science.aan5222">703</jats:related-article> </jats:p>
