In the Materials and Methods section, there is an error in the fifth and sixth sentences of the section titled “Flow cytometry.” This sentence should read: 2), PE-Cy5-conjugated anti-TCRβ (BioLegend, San Diego, CA), PE-Cy7-conjugated ant-NK1.1 (BioLegend), PE-Cy7-conjugated anti-CD8a (BioLegend), PE-CF594-conjugated anti-CD4 (BD Biosciences), and GPR30 (N-15)-R Antibody (Santa Cruz Biotechnology, Santa Cruz, CA) with subsequent staining by Alexa Fluor 488-conjugated goat anti-rabbit immunoglobulin G (IgG) (Invitrogen, Grand Island, NY). Then, the cells were washed, permeabilized with BD Cytofix/Cytoperm (BD Biosciences), and stained with PE-conjugated anti-IL-10 (BioLegend) to detect intracellular IL-10.
