  • Beschreibung: <jats:title>For T cells, variety is the spice of life</jats:title> <jats:p> CD4 <jats:sup>+</jats:sup> helper T cells come in a variety of flavors. This allows them to respond in a manner that is tailored to the pathogen they encounter. Becattini <jats:italic>et al.</jats:italic> wondered whether multiple “flavors” of human CD4 <jats:sup>+</jats:sup> T cells respond to specific stimuli or if just one flavor dominates. To find out, they stimulated human memory CD4 <jats:sup>+</jats:sup> T cells with a fungus, a bacteria, or a vaccine antigen. Multiple helper cell subsets participated in each response. T cell receptor sequencing revealed that in some cases, T cells with the same specificity acquired different helper cell fates. Thus, there is more heterogeneity in human T cell responses than previously appreciated. </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="6220" page="400" related-article-type="in-this-issue" vol="347" xlink:href="10.1126/science.1260668">400</jats:related-article> </jats:p>
