Junctional epidermolysis bullosa (JEB) patients experience skin and epithelial fragility due to a pathological deficiency in genes associated with epidermal adhesion. Disease severity ranges from post-natal lethality to localized skin involvement with persistent blistering followed by granulation tissue formation and atrophic scarring. We evaluated the potential of utilizing Trametinib, an MEK inhibitor previously shown to target fibrosis, with and without the documented EB-anti-fibrotic Losartan for reducing disease severity in a mouse model of JEB; Lamc2jeb mice. We found that Trametinib treatment accelerated disease onset and decreased epidermal thickness, which was in large part ameliorated by Losartan treatment. Interestingly, a range …

Dermatomyositis is a rare disease which affects the skin and muscles. This disease can manifest in children or not present until one is older. Since this disease is so rare, most individuals who are diagnosed with it will have a team of physicians who work together to help treat the patient.

Gout is a syndrome caused by an inflammatory response creating an over production of uric acid increasing uric acid levels in the blood and body fluids. Gout is defined as a disorder resulting from tissue deposition of MSU crystals (in joints, bursae, bone, and certain other soft tissues, such as ligaments, tendons and occasionally, skin) and/or crystallization of uric acid within the renal collecting system (tubules and renal pelvis) that typically occurs in acid urine” (Terkeltaub & Edwards, 2013, p. 20). Gout is among the oldest diseases affecting approximately 3.9% of adults in America (Terkeltaub & Edwards, 2013, p. xv). …

The molecular mechanisms underlying the putative role of osteopontin in the chronic inflammatory disease rheumatoid arthritis are unclear. A study in a murine model of arthritis now demonstrates that a specific antibody directed against the exposed osteopontin epitope SLAYGLR is capable of preventing inflammatory cell infiltration in arthritic joints.

In spontaneous inflammatory arthritis of K/BxN T cell receptor transgenic mice, the effector phase of the disease is provoked by binding of immunoglobulins (Igs) to joint surfaces. Inflammatory cytokines are known to be involved in human inflammatory arthritis, in particular rheumatoid arthritis, although, overall, the pathogenetic mechanisms of the human affliction remain unclear. To explore the analogy between the K/BxN model and human patients, we assessed the role and relative importance of inflammatory cytokines in K/BxN joint inflammation by transferring arthritogenic serum into a panel of genetically deficient recipients. Interleukin (IL)-1 proved absolutely necessary. Tumor necrosis factor (TNF)-alpha was also …
