In fact, a study by Uhm et al. sought to understand whether the regulation, by GATA-1, of C-C motif chemokine receptor 3 (CCR3), a gene known to regulate eosinophil recruitment into tissues largely associated with allergies and asthma [70], could be explained by DNA methylation in eosinophil samples. The gene discussed is CCR3; the disease is asthma.
