abstract = {Regulatory T cells (Tregs) control adaptive immunity and
restrain type 2 inflammation in allergic disease.
Interleukin-33 promotes the expansion of tissue-resident
Tregs and group 2 innate lymphoid cells (ILC2s); however,
how Tregs locally coordinate their function within the
inflammatory niche is not understood. Here, we show that
ILC2s are critical orchestrators of Treg function. Using
spatial, cellular, and molecular profiling of the type 2
inflamed niche, we found that ILC2s and Tregs engage in a
direct (OX40L-OX40) and chemotaxis-dependent (CCL1-CCR8)
cellular dialogue that enforces the local accumulation of
Gata3high Tregs, which are transcriptionally and
functionally adapted to the type 2 environment. Genetic
interruption of ILC2-Treg communication resulted in
uncontrolled type 2 lung inflammation after allergen
exposure. Mechanistically, we found that Gata3high Tregs can
modulate the local bioavailability of the costimulatory
molecule OX40L, which subsequently controlled effector
memory T helper 2 cell numbers. Hence, ILC2-Treg
interactions represent a critical feedback mechanism to
control adaptive type 2 immunity.},
