Through establishing an interleukin (IL)-1-stimulated chondrocytes, it was found that L-theanine could inhibit the nuclear factor kappa B (NF-B) pathway, thereby reducing the expression of proinflammatory factors, including cyclooxygenase-2 (COX-2), prostaglandin E2, inducible nitric oxide synthase, as well as NO, and protect the degradation of extracellular matrix ( In summary, the anti-inflammatory activity of L-theanine can be associated with inhibiting the expression of inflammatory factors and inflammation-related signaling pathways
Thus, evidence suggests that an increased release of coagulation factors and dysregulation and destruction of the endothelial cells are the main mechanisms of the increase in thromboembolism in patients with COVID-19 (ref
Everyone in the trial also received nicotine replacement therapy patches and brief smoking cessation counseling
