Consistent Inhibition of Cyclooxygenase Drives Macrophages towards the Inflammatory Phenotype

Consistent Inhibition of Cyclooxygenase Drives Macrophages towards the Inflammatory Phenotype

Macrophages play important roles in defense against infection, as well as in homeostasis maintenance. Thus alterations of macrophage function can have unexpected pathological results. Cyclooxygenase (COX) inhibitors are widely used to relieve pain, but the effects of long-term usage on macrophage function remain to be elucidated. Using bone marrow-derived macrophage culture and long-term COX in...

Inhibition of SIK2 and SIK3 during differentiation enhances the anti-inflammatory phenotype of macrophages

The salt-inducible kinases (SIKs) control a novel molecular switch regulating macrophage polarization. Pharmacological inhibition of the SIKs induces a macrophage phenotype characterized by the secretion of high levels of anti-inflammatory cytokines, including interleukin (IL)-10, and the secretion of very low levels of pro-inflammatory cytokines, such as tumour necrosis factor α. The SIKs, the...

Myelin alters the inflammatory phenotype of macrophages by activating PPARs

BACKGROUND Foamy macrophages, containing myelin degradation products, are abundantly found in active multiple sclerosis (MS) lesions. Recent studies have described an altered phenotype of macrophages after myelin internalization. However, mechanisms by which myelin affects the phenotype of macrophages and how this phenotype influences lesion progression remain unclear. RESULTS We demonstrate ...

Inflammatory Response Implications for the Nature of the Macrophages Is Stimulus Dependent: The Phenotype of Inflammatory

The effect of eight weeks of combined training on the serum macrophages phenotype of cardiac patients after coronary bypass surgery

Introduction: Cardiovascular disease, including atherosclerosis, has an inflammatory background on a molecular scale. In the immune system, various factors activate macrophages, which ultimately lead to various macrophage activities in inflammatory and non-inflammatory conditions. The aim of the present study was to investigate the effect of eight weeks of combined training on serum macrophage ...
