RNA was harvested from small intestine ILC2 of WT and Melttl3 Klrg1Cre mice using miRNeasy Micro Kit (Qiagen). Then m6A immunoprecipitation (meRIP) was performed to obtain the pellet fractions, which were used for the construction of sequencing libraries. cDNA libraries for RNA-seq were prepared using NEBNext Single Cell/Low Input RNA Library Prep Kit for Illumina® following manufacturer's protocols.
