The mRNA levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and monocyte chemoattractant protein-1 (MCP-1) were lower in the HPG group than in the HF group (p < 0.05), whereas WEG treatment did not affect these levels significantly (Figure 5b). Here, CCL2 is linked to hydrops fetalis.
