Thymol on Netrin-1 on Obese Patients

Summary

The prevalence of obesity in Mexico is 35.4%, and it is considered a risk factor for the development of diabetes, systemic arterial hypertension and dyslipidemia. Obesity due to the increased distribution and growth of adipose tissue creates a pro-inflammatory state induced by molecules secreted by the adipocytes themselves. Netrin-1 is a cell migration protein, which directs the recruitment, migration and entrapment of macrophages in different tissues, within adipose tissue the entrapment of macrophages induces the release of pro-inflammatory cytokines, which increase the secretion of pro-inflammatory adipokines. It has been found in high concentration in patients with obesity, insulin resistance and type 2 diabetes. Thymol is a phytopharmaceutical derived from oregano oil that has shown powerful anti-inflammatory and antioxidant effects through the stimulation of PPAR-gamma, adiponectin and inhibition of the NF-κB pathway mediated by the JNK pathway, pathways in which netrin-1 is involved in macrophage entrapment and recruitment.
