Abstract
Type 2 helper T cells (TH2 cells) produce interleukin 13 (IL-13) when stimulated by papain or house dust mite extract (HDM) and induce eosinophilic inflammation. This innate response is dependent on IL-33 but not T cell antigen receptors (TCRs). While type 2 innate lymphoid cells (ILC2 cells) are the dominant innate producers of IL-13 in naive mice, we found here that helminth-infected mice had more TH2 cells compared to uninfected mice, and thes e cells became major mediators of innate type 2 responses. TH2 cells made important contributions to HDM-induced antigen-nonspecific eosinophilic inflammation and protected mice recovering from infection with Ascaris suum against subsequent infection with the phylogenetically distant nematode Nippostrongylus brasiliensis. Our findings reveal a previously unappreciated role for effector TH2 cells during TCR-independent innate-like immune responses.

Supplementary Figure 1 The expression of fluorescent proteins in 4C13R dual-reporter mice is a reliable reporter of cytokine production.
Naïve CD4 T cells were sorted from 4C13R dual reporter mice and cultured under TH2 conditions (a,b) or TH17 conditions (c) for two rounds. Cells were stimulated with PMA plus ionomycin or IL-33 plus IL-7 for 4 hours in the presence of monensin. Cytokine production was measured by intracellular staining. Data are representative of at least three independent experiments.
Supplementary Figure 2 Administration of IL-33 and TSLP induces TH2 cells to produce IL-13.
(a) Naïve CD4 T cells were sorted from OT-II–4C13R reporter mice and cultured under TH2 conditions for three rounds. Cells were rested in IL-7-containing medium for 10 days and then injected i.v. into wild-type C57BL/6 recipient mice. Twenty-four hours later, mice were intratracheally challenged with PBS or indicated cytokines (150 ng IL-33 and/or 150 ng TSLP each mouse) for 3 consecutive days, or OVA (100 μg endotoxin-free OVA in PBS) once. Lungs were collected and cytokine production was examined 24h after last cytokine administration. Cells shown were gated on transferred OT-II TH2 cells. (b) Statistical analysis of the cytokine production. Error bars represent standard deviation from the mean. ****, P<0.0001; ns, P>0.05 by two tailed student’s t-test.

In some mice, 500 μg anti-MHCII antibody was administered i.v. on Day 1 and Day 3 of OVA stimulation. Lungs were collected 72h after OVA challenge; DsRed and AmCyan expression by transferred OT-II TH2 cells were analyzed.

Supplementary Figure 5 Previous infection with A. suum. protects mice against a subsequent infection with N. brasiliensis.
(a) C57BL/6 mice were inoculated with A. summ eggs orally. After the indicated periods, mice received a subsequent subcutaneous inoculation with 500 N. brasiliensis L3. The mice in control group were only inoculated subcutaneously with 500 N. brasiliensis L3. (b) N. brasiliensis adult worms in the small intestine were determined on day 8 post N. brasiliensis inoculation. ***, P<0.001. Data are representative of one experiment with three mice in each group.
Supplementary Figure 6 Substantial reduction in ILC2 cells in chimeras reconstituted with RORα-deficient BM.
8 weeks after bone marrow reconstitution, lungs from WT or RORα-deficient BM chimeras were collected and single cell suspension was prepared. Frequency of lung-resident ILC2 (live Lin–CD127+GATA3+RORγt– lymphocytes) and ILC3 (live Lin–CD127+GATA3–RORγt+ lymphocytes) cells were analyzed in two individual mice from each group. Data are representative of one experiment with two mice in each group.
Supplementary Figure 7 Induction of ILC2 cells in BM chimeras.
WT or RORα-deficient BM chimeras were infected as Fig. 7g. In some mice (c), mice were i.v. injected with 500 μg anti-CD4 antibody on Day1 and Day4 of N. brasiliensis inoculation. (a) Proportion of lung-resident ILC2 cells in WT and RORα-deficient BM chimeras 8 days after they received N. brasiliensis inoculation. (b-d) WT and RORα-deficient BM chimeras that have been inoculated with A. suum and subsequently with N.brasiliensis were analyzed 8 days post N. brasiliensis inoculation. Adult N. brasiliensis worm burden in intestine vs the proportion of the lung-resident ILC2 cells were plotted. Data are compiled from three independent experiments with 4-5 mice each group.
Supplementary Figure 8 Wild-type and RORα-deficient TH2 cells produce similar amounts of cytokines in response to PMA plus ionomycin or IL-33 plus IL-7.
Naïve CD4 T cells were sorted from WT or RORα-deficient BM chimeras. T cells were cultured under TH2 conditions with anti-CD3 and anti-CD28 in the presence of APC for two rounds. To test cytokine production, cells were stimulated with (a) PMA and ionomycin or (b) IL-33+IL-7 in the presence of monensin for 4h. Cytokine production was examined by intracellular staining. Data are representative of two independent experiments.
