Andrographolide, a diterpenoid lactone obtained from plant Andrographis paniculata, is used in South Asian countries to relieve various inflammatory symptoms. To study the effects of this agent, the impact of andrographolide on production of inflammatory mediators were delineated in mouse peritoneal macrophages (PMϕ). Inflammatory mediators like nitric oxide (NO), tumor necrosis factor (TNF)-α, interleukin-6 and related molecular mechanisms of andrographolide-mediated inhibition of enzymes/transcription factors were studied...

Rheumatoid arthritis and spondyloarthritis are inflammatory joint disorders with an autoimmune pathogenesis and systemic involvement. The skin is one of the most frequently affected extraarticular sites with a number of manifestations or distinct diseases, including common conditions, such as rheumatoid nodules and psoriasis, and rare diseases like neutrophilic dermatoses. The latter are clinically characterised by polymorphic lesions, including pustules, bullae, abscesses, papules, nodules, plaques and ulcers, and histologically by neutrophil-rich inflammatory infiltrates...

Bones are inflexible yet ever-changing metabolic organs, and bone homeostasis is maintained through two delicately regulated processes: bone construction and bone reabsorption. An imbalance in bone metabolism is linked to most orthopedic diseases, including osteoporosis and rheumatoid arthritis. Importantly, tumor necrosis factor-α (TNF-α) blocks osteoblast differentiation and stimulates osteoclast formation, resulting in delayed deposition of new bone and accelerated bone resorption, especially in rheumatoid arthritis patients with inflammatory conditions...

Rheumatoid arthritis (RA) is a chronic and autoimmune-mediated inflammatory disease. We aimed to investigate the regulation of lncRNA HOTAIR in LPS-treated chondrocytes and RA mouse. Our results showed that HOTAIR expression was significantly reduced in LPS-treated chondrocytes. The HOTAIR was then over-expressed in chondrocytes by transfecting recombinant lentivirus carrying sequences encoding HOTAIR. The LPS-induced reduction of cell proliferation rate and production of two inflammatory factors interleukin (IL)-17, IL-23 were markedly inhibited...

Osteoclasts are responsible for the bone erosion associated with rheumatoid arthritis (RA). The upregulation of the chemokines CCL19 and CCL21 and their receptor CCR7 has been linked to RA pathogenesis. The purpose of this study was to evaluate the effects of CCL19 and CCL21 on osteoclasts and to reveal their underlying mechanisms. The expression of CCL19, CCL21 and CCR7 was higher in RA patients than in osteoarthritis patients. In differentiating osteoclasts, tumor necrosis factor-α, interleukin-1β and lipopolysaccharide stimulated CCR7 expression...

An imbalance in pro- and anti-inflammatory cytokines is suggested to contribute to tissue damage in rheumatoid arthritis (RA). This study was aimed at investigating profiles of cytokines in circulation and cytokines produced by mitogen-stimulated peripheral blood mononuclear cells (PBMC) in RA patients and healthy controls, and to explore correlations of cytokines with disease activity. Our aim was to identify patterns of cytokine expression as possible indicators of disease activity. Levels of plasma cytokines and PBMC-secreted cytokines were estimated in 26 female RA patients and 28 controls...

In the past years, pediatric rheumatology has seen a revolution in the treatments for rheumatic diseases, particularly juvenile idiopathic arthritis. Even if nonsteroidal anti-inflammatory drugs (NSAID), intra-articular corticosteroids (IAC) injections, and methotrexate remain the mainstay of the treatment for JIA patients, in aggressive disease, these treatments may be not sufficient to reach disease remission and to prevent long-term disability. Comprehension of immunological mechanisms involved in the pathogenesis of the diseases allowed to conceive new drugs targeting specific steps of the immune response...

Curcumin is a natural anti-inflammatory agent that has been used for treating medical conditions for many years. Several experimental and pharmacologic trials have demonstrated its efficacy in the role as an anti-inflammatory agent. Curcumin has been shown to be effective in treating chronic conditions like rheumatoid arthritis, inflammatory bowel disease, Alzheimer's and common malignancies like colon, stomach, lung, breast, and skin cancers. As treatments in medicine become more and more complex, the answer may be something simpler...

BACKGROUND: Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by uncontrolled joint inflammation and destruction of bone and cartilage. We previously reported that C-X-C motif chemokine 10 (CXCL10; also called IP-10) has important roles in joint inflammation and bone destruction in arthritis. However, the specific mechanisms by which CXCL10 regulates the recruitment of inflammatory cells and the production of osteoclastogenic cytokines in RA progression are not fully understood...

Hypoxia augments inflammatory responses and osteoclastogenesis by incompletely understood mechanisms. We identified COMMD1 as a cell-intrinsic negative regulator of osteoclastogenesis that is suppressed by hypoxia. In human macrophages, COMMD1 restrained induction of NF-κB signaling and a transcription factor E2F1-dependent metabolic pathway by the cytokine RANKL. Downregulation of COMMD1 protein expression by hypoxia augmented RANKL-induced expression of inflammatory and E2F1 target genes and downstream osteoclastogenesis...

Rheumatoid arthritis (RA) is a systemic and chronic inflammatory disease. Synoviocyte migration and invasion were found to be essential to the pathology of RA. Upregulation of long noncoding RNA ZFAS1 has been observed in cancers and promotes cell migration and invasion. To date, the functions and mechanisms of ZFAS1 in RA have not been revealed. In this study, we analyzed expression pattern of ZFAS1 in RA patients and found that ZFAS1 expression was increased in synovial tissue and fibroblast-like synoviocytes (FLS) from RA patients (RA-FLS) compared with that in healthy donors...

Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune destructive arthropathy prevalent among people in the age group of 40-70 years. RA induces severe pain, swelling and stiffness of joints resulting in bone damage. RA leads to reduced life expectancy when left untreated. RA is characterized by synovial hyperplasia, infiltration of inflammatory cells resulting in formation of pannus. Synovial hyperplasia is mediated by proinflammatory cytokines, notably IL-1 and TNF-α. NF-κB is a predominant transcription factor in amplifying the inflammatory response...

Rheumatoid arthritis (RA) is a chronic inflammatory disease affecting the hand joints and leading to impairment in hand functions. Evaluation of functional impairment is necessary for assessing patient's quality of life, disease activity, and treatment outcome. To date, many scientific studies assessed the disease activity of patients with RA, but little attention has been carried out to assess these patients' hand functions and dexterity. The purposes of this study were to determine the clinical relevance of the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH), hand dexterity with the Purdue Pegboard Test (PPT), and handgrip strength and pinch strengths of RA patients and to look into their relation between each other...
