We found that the expression of Iba1+IL-4+ or Iba1+IL-10+ cells in the AD group (average 5.4 for IL-4 and 4.8 for IL-10 in CA1) was two times less than the Control (average 14.0 for IL-4 and 11.2 for IL-10) and NS (average 12.4 for IL-4 and 10.2 for IL-10) groups in CA1 (p < 0.05). Here, IL4 is linked to Alzheimer disease.
