These factors include the interleukins, such as IL‐1, IL‐6, and IL‐8, monocyte chemoattractant protein (MCP)‐1, TNF‐α, and granulocyte‐macrophage colony‐stimulating factor (GM‐CSF), which collectively play crucial roles in various inflammatory problems such as atopic dermatitis and psoriasis [69, 70, 71]. Here, CCL2 is linked to psoriasis.
