When investigating the role of epigenetic modifiers in inflammatory response, researchers found that Tet2 acts at the chromatin level to help resolve inflammation in both dendritic cells and macrophage, repressing the transcription of IL-6…
Bronchial Tissue Immune Activation Seen in Early Rheumatoid Arthritis
NEW YORK (Reuters Health)—Patients with untreated early rheumatoid arthritis (RA) show signs of immune activation and local inflammation in their bronchial tissues, researchers from Sweden report. Previous studies have shown that patients with RA have shared citrullinated epitopes in the lungs and joints, as well as anticitrullinated protein antibodies (ACPA) in bronchoalveolar lavage (BAL), suggesting…
Low-Grade Inflammation in Symptomatic Knee OA
Although osteoarthritis (OA) was formerly considered a non-inflammatory joint disease, it’s now well-appreciated that inflammatory mediators, such as PGE2 and IL-1β, are produced by osteoarthritic joint tissues and can be used to identify patients with symptomatic knee OA. A peripheral blood leukocyte inflammatory transcriptome identifies a subset of symptomatic knee OA patients at higher risk for radiographic progression and may reflect persistent low-grade joint inflammation…
POP1-Based Treatments May Reduce Inflammation
A recent study analyzed inflammasome response, finding the POP1 PYRIN domain protein acts to decrease excessive inflammatory responses and prevent systemic inflammation. Researchers ultimately developed a drug based on POP1 and found it reduced inflammation in mice…
Increased Risk of Serious Infections During Early Anti-TNF Treatment
NEW YORK (Reuters Health)—The risk of serious infections increases in the early months of anti-TNF treatment for inflammatory bowel disease, researchers from Denmark report. “The pro-inflammatory cytokine TNF-alpha plays an important role in the immune system and therefore it is biologically plausible that TNF-alpha inhibitors may increase the risk of infections,” said Dr. Nynne Nyboe…
Anti-TNF Agents May Improve Clinical Symptoms of Ankylosing Spondylitis
Ankylosing spondylitis primarily affects the joints and ligaments of the spine, but may also have an impact on other joints. Patients experience pain and stiffness that limit mobility in the back and other affected joints. Symptoms can come and go, last for long periods of time and be severe. Anti-tumor necrosis factor (anti-TNF) drugs are…
