Description:
Changes to the symbiotic microbiota early in life, or the absence of it, can lead to exacerbated type 2 immunity and allergic inflammations. Although it is unclear how the microbiota regulates type 2 immunity, it is a strong inducer of proinflammatory T helper 17 (T(H)17) cells and regulatory T cells (T(regs)) in the intestine. Here, we report that microbiota-induced T(regs) express the nuclear hormone receptor RORgammat and differentiate along a pathway that also leads to T(H)17 cells. In the absence of RORgammat(+) T(regs), T(H)2-driven defense against helminths is more efficient, whereas T(H)2-associated pathology is exacerbated. Thus, the microbiota regulates type 2 responses through the induction of type 3 RORgammat(+) T(regs) and T(H)17 cells and acts as a key factor in balancing immune responses at mucosal surfaces.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ohnmacht, Caspar -- Park, Joo-Hong -- Cording, Sascha -- Wing, James B -- Atarashi, Koji -- Obata, Yuuki -- Gaboriau-Routhiau, Valerie -- Marques, Rute -- Dulauroy, Sophie -- Fedoseeva, Maria -- Busslinger, Meinrad -- Cerf-Bensussan, Nadine -- Boneca, Ivo G -- Voehringer, David -- Hase, Koji -- Honda, Kenya -- Sakaguchi, Shimon -- Eberl, Gerard -- New York, N.Y. -- Science. 2015 Aug 28;349(6251):989-93. doi: 10.1126/science.aac4263.
