Macrophages play an important role in tissue repair and remodeling and innate immune response. Tissue macrophages are highly heterogeneous and can undergo 2 distinct programs of functional specification termed classical (M1) and alternative (M2) activation.1,2 In response to signals elicited by bacterial infections, such as lipopolysaccharide (LPS) and interferon, macrophages adopt a proinflamm...

NASH consists in lipid accumulation in hepatocytes that trigger oxidative stress, secretion of proinflammatory cytokines leading to steatohepatitis (NASH). The study aimed to investigate the levels of proinflammatory (TNF-α and IL-6) along with anti-inflammatory cytokine IL-10 in patients with NASH and to correlate the cytokines' level with their polymorphism. Sixty-six patients with NASH and 3...

Oligonucleotides with a "CpG" motif trigger a proinflammatory response through activation of Toll-like receptor 9 (TLR9) and are being studied to exploit these properties for use as adjuvants and cancer therapies. However, oligonucleotides intended for antisense applications (ASOs) are designed to minimize proinflammatory responses by avoiding CpG motifs and by using chemical modifications [i.e...

Atherosclerotic lesions are accelerated in patients with diabetes. M1 (classically activated in contrast to M2 alternatively activated) macrophages play key roles in the progression of atherosclerosis. Since advanced glycation end products (AGEs) are major pathogenic factors and active inflammation inducers in diabetes mellitus, this study assessed the effects of AGEs on macrophage polarization...

Chronic brain inflammation is associated with Alzheimer's disease (AD) and is classically attributed to amyloid plaque deposition. However, whether the amyloid pathology can trigger early inflammatory processes before plaque deposition remains a matter of debate. To address the possibility that a pre-plaque inflammatory process occurs, we investigated the status of neuronal, astrocytic, and mic...

AIMS Inflammation, endothelial cell function and the coagulation system have been demonstrated to be involved in the onset and course of unstable angina. Whether a proinflammatory state independently determines outcome is unknown and has not been determined yet in a clinically well defined study population of consecutive patients admitted with unstable angina. METHODS AND RESULTS Markers of i...

The role of immunity in blinding trachoma is unclear. Conjunctival gene expression was measured in a population where trachoma is endemic. Proinflammatory (tumor necrosis factor alpha and interleukin-1beta [IL-1beta]), anti-inflammatory (IL-10), and fibrogenic (matrix metalloprotease 9) gene expression was increased in active trachoma. Markers indicative of T-cell response (gamma interferon, IL...
