PTPRC and obesity due to melanocortin 4 receptor deficiency: The ratios of ILC1s in CD45 positive cells, which have been reported to promote adipose tissue fibrosis and diabetes [21] in the eWAT of the Ery group, were significantly lower than those in the eWAT of the Ctrl group (p = 0.001; Figure 5A), whereas the ratios of ILC2s in CD45 positive cells, which have been reported to promote beiging of WAT and suppress obesity [13] in the Ery group, were significantly higher than those in the Ctrl group (p = 0.029; Figure 5B).
