Figure 5 illustrates this finding (the higher CD127low Treg cell numbers in the group with neuropathy, p = 0.04). When Tregs were gated as FoxP3 positive cells (CD4+CD25highFoxP3+) or as the combination of CD127low and FoxP3 (CD4+CD25highCD127lowFoxP3+), positive correlations in regard to the presence of diabetic neuropathy were still apparent but failed to reach significant levels (p = 0.369 for CD4+CD25highFoxP3+ and p = 0.169 for CD4+CD25highCD127lowFoxP3+). Here, CD4 is linked to neuropathy.
