MMP-13, VEGF, and Disease Activity in a Cohort of Rheumatoid Arthritis Patients.

Identifying certain serum biomarkers associated with the degree of rheumatoid arthritis (RA) activity can provide us with a more accurate view of the evolution, prognosis, and future quality of life for these patients. Our aim was to analyze the presence and clinical use of matrix metalloproteinase-13 (MMP-13), along with vascular endothelial growth factor (VEGF) and well-known cytokines such as tumor necrosis factor-alpha (TNF-α) and interleukin 6 (IL-6) for patients with RA. We also wanted to identify the possible correlations between MMP-13 and these serological markers, as well as their relationship with disease activity indices, quality of life, and ultrasonographic evaluation.

JAK/STAT pathway in pathology of rheumatoid arthritis (Review).

Rheumatoid arthritis (RA) is classified as an inflammatory, chronic autoimmune and disabling disease based on the intricate interplay between environmental and genetic factors. With a prevalence ranging from 0.3 to 1%, RA is the most prevalent inflammatory joint disease observed in adults.

New insights into IL-17/IL-23 signaling in ankylosing spondylitis (Review).

Ankylosing spondylitis (AS) is a progressive common autoimmune inflammatory disease, part of the spondylarthritis group, characterized, besides clinical spinal and peripheral joint inflammation, by enthesitis and new bone formation, that can lead to severe functional impairment. Beyond intensive and continuous research on the pathogenic process extensively performed in recent years, their impact on therapeutic management remains open to future development. Better knowledge of AS pathogenesis have shown results progressively and studies are being performed to advance our current understanding of the disease.

Neuroinflammation in systemic lupus erythematosus - a review.

Neuroinflammation is a complex process that contributes to the pathogenesis of both immune mediated and neurodegenerative pathologies. Systemic lupus erythematosus (SLE) is the prototype of connective tissue diseases that can present the complete spectrum of neurological and psychiatric dysfunctions. The precise etiological diagnosis of neuropsychiatric systemic lupus erythematosus (NPSLE) is rather difficult to be established and it is still controversial the exact timing of neuropsychiatric (NPS) events: either central nervous system (CNS) is the initial target of autoimmune abnormalities, either NPS symptoms are a part of multisystem involvement.
