Interestingly, protection from colitis by co-transfer of Foxp3+ regulatory T (Treg) cells with colitogenic CD4+ T cells reduced not only cLPL neutrophil numbers but also eosinophil accumulation and activation, indicating similar inhibitory effects of Treg cells on neutrophils and eosinophils in this model (Figure S1C). The gene discussed is CD4; the disease is colitis.
