Evaluation of alternative pathway in macrophages from diabetic 5LO−/− or WT mice. Resident peritoneal macrophages from WT or 5LO−/− mice, healthy or diabetic (T1D), were collected for the analysis of Il4r (A) and Stat6 (B) expression by qPCR. Total and phosphorylated STAT6 was also analyzed by western blot (C,D). Cells were stimulated with recombinant IL-4 (4000, 400 or 40 ng), and the expression of total STAT6 and phosphorylated (p-STAT6) and β-Actin were analyzed by western blot (C–E). Full-length blots/membranes are presented in Supplementary Figures 3 (loading control), 4 (total STAT6), 5 (p-STAT6) and 6 (β-Actin). Data are presented as the mean ± SEM of 3 to 5 animals per group. *p ≤ 0.05 when the diabetic groups were compared to healthy WT, #p ≤ 0.05 when diabetic 5LO−/− group was compared to diabetic WT. &p ≤ 0.05 when IL-4 groups were compared to control (CT) groups. H = healthy.
