However, targeting the CCL2 pathway may have some unintended toxicity consequences as CCL2 can be expressed by a range of non-tumour cell types, including endothelium, smooth muscle, and fibroblasts and is implicated in multiple conditions, such as rheumatoid arthritis, asthma, inflammatory bowel disease, and SARS-CoV-2 infection [62,63]. The gene discussed is CCL2; the disease is inflammatory bowel disease.
