Wnt5a initiates pro-inflammatory responses through activation of non-canonical Wnt signaling pathway. Pro-inflammatory functions of Wnt5a trigger pro-inflammatory signaling cascades and increase secretion of pro-inflammatory cytokines and chemokines. Wnt5a as a potent signaling molecule is strongly implicated in a number of diseases including cancer, diabetes, metabolic disorders, and of special interest in this review, inflammatory diseases. This review summarizes the role of Wnt5a in the pathogenesis of inflammatory diseases including atherosclerosis, rheumatoid arthritis, psoriasis vulgaris and sepsis, promoting greater understanding, and clinical management of these diseases.

Atherosclerosis is an arterial disease associated with inflammation. Thrombin is a procoagulant and proinflammatory serine protease that contributes to the pathology of atherosclerosis by enhancing the expression of cell adhesion molecules, inducing the secretion of proinflammatory cytokines, activating inflammatory responses in atherosclerotic plaques, stimulating proliferation of aortic smooth muscle cells, and exacerbating vascular lesions at sites of injury. Hence, thrombin appears to be an important target for treatment of atherosclerosis and thrombin pharmacological inhibitors have significant therapeutic potency for suppressing inflammatory responses in cardiovascular diseases. This review summarizes the proinflammatory signaling functions of thrombin as well as the therapeutic potency of thrombin inhibitors in the pathogenesis of atherosclerosis and hence their potential therapeutic value in this condition.

The transforming growth factor-β (TGF-β) signaling pathway plays an important role in cancer cell proliferation, growth, metastasis, and apoptosis. It has been shown that TGF-β acts as a tumor suppressor in the early stages of the disease, and as a tumor promoter in its late stages. Mutations in the TGF-β signaling components, the TGF-β receptors and cytoplasmic signaling transducers, are frequently observed in colorectal carcinomas. Exploiting specific TGF-β receptor agonist and antagonist with antitumor properties may be a way of controlling cancer progression. This review summarizes the regulatory role of TGF-β signaling in the pathogenesis of colorectal cancer.

Crocin is the major component of saffron, which is used in phytomedicine for the treatment of several diseases including diabetes, fatty liver, depression, menstruation disorders, and, of special interest in this review, inflammatory diseases. Promising selective anti‐inflammatory properties of this pharmacological active component have been observed in several studies. Saffron has been shown to exert anti‐inflammatory properties against several inflammatory diseases and can be used as a novel therapeutic agent for the treatment of inflammatory diseases either alone or in combination with other standard anti‐inflammatory agents. This review summarizes the protective role of saffron and its pharmacologically active constituents in the pathogenesis of inflammatory diseases including digestive diseases, dermatitis, asthma, atherosclerosis, and neurodegenerative diseases for a better understanding and hence a better management of these diseases.
