Publisher Correction: Gut CD4 + T cell phenotypes are a continuum molded by microbes, not by T H archetypes

In the version of this article initially published, in the second paragraph of Results section “Teff phenotypes over time,” “Tcra and Tcra genes” should have read “Tcra and Tcrb genes.” In numbered paragragh 3 of “New Teff populations,” “C1q” should have read “C1qa.” In the first paragraph of Methods, “Cd45.1-/-;Cd45.2-/- mice” should have read “CD45.1+CD45.2+ mice.” Finally, the wrong image was posted for Extended Data Fig. 5. The errors have been corrected in the PDF and HTML versions of the article. (Figure presented.).
