Cathepsin K is a cysteine protease member of the cathepsin lysosomal protease family. While cathepsin K is highly expressed in osteoclasts, lower levels of cathepsin K are also found in a variety of other tissues. Secretion of cathepsin K from the osteoclast into the sealed osteoclast-bone cell interface results in efficient degradation of type I collagen. The absence of cathepsin K activity in humans results in pycnodysostosis, characterized by increased bone mineral density and fractures. Pharmacological cathepsin K inhibition leads to continuous increases in BMD for up to five years of treatment and improves bone strength at the spine and hip...

The topical application of Centella asiatica extract has been commonly used for many different purposes but especially for cosmetic use in the treatment of gynoid lipodystrophy. Asiaticoside, the most active component in this extract, is responsible for its therapeutic activities. However, little is known to date about asiaticoside skin penetration. Thus, an analytical method for asiaticoside quantification in different skin layers after the topical application of C. asiatica extract was developed and skin permeation studies were performed with the plant extract to apply the analytical method developed...

Reconstructed skin models are suitable test systems for toxicity testing and for basic investigations on (patho-)physiological aspects of human skin. Reconstructed human skin, however, has clear limitations such as the lack of immune cells and a significantly weaker skin barrier function compared to native human skin. Potential reasons for the latter might be the lack of mechanical forces during skin model cultivation which is performed classically in static well-plate setups. Mechanical forces and shear stress have a major impact on tissue formation and, hence, tissue engineering...

Lemierre syndrome is an uncommon condition in which internal jugular vein thrombosis presents after recent oropharyngeal infection. Frequently, this is accompanied by septic emboli. This report outlines a variant of this disease process, with septic thrombophlebitis of the neck associated with a necrotizing skin infection of the lower lip and chin. A 25-year-old man with lower lip and chin swelling, initially managed with intravenous antibiotics, progressed to the development of a left facial vein thrombus, septic emboli to the lungs, and a necrotizing lower lip and chin infection that was managed with debridement, thrombectomy, and prolonged hemodynamic and pulmonary support...

The murine bleomycin (BLM)-induced fibrosis model is the most widely used in systemic sclerosis (SSc) studies. It has been reported that systemic delivery of BLM via continuous diffusion from subcutaneously implanted osmotic minipumps can cause fibrosis of the skin, lungs, and other internal organs. However, the mouse strain, dosage of BLM, administration period, and additional important features differ from one report to the next. In this study, by employing the pump model in C57BL/6J mice, we show a dose-dependent increase in lung fibrosis by day 28 and a transient increase in dermal thickness...

p23 is a small acidic protein with intrinsic molecular chaperone activity. It is best known as a co-chaperone of the major cytosolic molecular chaperone Hsp90. p23 binds the N-terminus of Hsp90 and stabilizes the ATP-bound and N-terminally closed Hsp90 dimer. It is in this configuration that many Hsp90 clients are most stably bound. Considering the important role of p23 in the Hsp90 cycle, it came as a surprise that it is not absolutely essential for viability in the budding yeast or for mouse development. Mice without p23 develop quite normally until birth and then all die perinatally because of immature lungs...

There are many types of biologic compartments in the body. Tight junctions (TJs) function to create a dynamic paracellular barrier to separate these compartments and maintain homeostasis. The TJ component claudin-1 is the major transmembrane protein responsible for forming the paracellular barrier in the epidermis; other claudins in the epidermis include claudin-3, -4, -12, -23 and -25. Accumulating evidence points to a relationship between claudin-1 and skin diseases; for example, a decrease in claudin-1 is reported in human atopic dermatitis...

The healing of chronic wounds remains a considerable challenge in clinical trials and imposes severe financial and physiological burdens on patients. Many works are being tried to find ideal clinical promoting-wound-healing biomaterials. Small bioactive peptides with low cost and easy production, store and transfer become excellent candidates. Here, we identified a novel peptide (named OM-LV20) from skin secretions of odorous frog Odorrana margaretae. The peptide had an amino acid sequence of 'LVGKLLKGAVGDVCGLLPIC', contained an intramolecular disulfide bridge at the C-terminus, and was produced by posttranslational processing of a 71-residue prepropeptide...

Diabetic foot ulcers (DFUs) are associated with an increased risk of secondary infection and amputation. Platelet-rich fibrin (PRF), a platelet and leukocyte concentrate containing several cytokines and growth factors, is known to promote wound healing. However, the effect of PRF on diabetic wound healing has not been adequately investigated. The aim of the study was to investigate the effect of PRF on skin wound healing in a diabetic mouse model. Platelet-rich fibrin was prepared from whole blood of 8 healthy volunteers...

The association of specific skin disorders with diabetes mellitus (DM) has been well established. Current literature suggests that approximately 30-91% of patients with diabetes will experience at least one cutaneous manifestation of this systemic disease in their lifetime. To date, there are limited articles summarizing the link between necrobiosis lipoidica diabeticorum (NLD) prognosis and glycemic control in patients with diabetes. The objective of the study is to summarize and appraise the available evidence assessing the relationship between glycemic control and NLD...

Psoriasis is a chronic immune-mediated inflammatory skin disease in which the alteration of the interleukin-23 (IL-23)/IL-17 cytokine axis appears to be crucial from a pathogenetic perspective. This has been confirmed by the efficacy of monoclonal antibodies blocking IL-17A, such as secukinumab and ixekizumab. Brodalumab is a human anti-IL-17 receptor A (IL-17RA) monoclonal antibody that inhibits the biological activity of IL-17A, IL-17F and other IL-17 isoforms, and has been approved (210 mg s.c. at weeks 0, 1, 2 and every 2 weeks thereafter) for the treatment of psoriasis vulgaris, psoriatic arthritis, pustular psoriasis and psoriatic erythroderma in Japan (Lumicef)...

Neonatal lupus (NL) is an acquired autoimmune disease of the newborn, caused by transplacental passage of the maternal autoantibodies anti SS-A/Ro and anti SS-B/La. When the clinical picture starts directly at birth, it is known as congenital lupus (CL). The clinical manifestations are variable. Except for cardiac involvement, the other manifestations tend to be benign, and resolve with the child's clearance of maternal antibodies. We report a patient who presented at birth with very severe involvement of the skin, and subsequent contractures of hands and feet, leading to functional impairment...

Platelets are a popular source of native growth factors for tissue engineering applications. The aim of the study was to verify the use of platelet lysate as a fetal bovine serum (FBS) replacement for skin cell culture. The cytokine content of the platelet lysate was characterized using the Bio-Plex system. The cells (fibroblasts, melanocytes, and keratinocytes) were cultured on PCL nanofibrous scaffolds to mimic their natural microenvironment. The cytokine content of the platelet lysate was determined, and to the cells, a medium containing platelet lysate or platelet lysate in combination with FBS was added...

T-cell lymphoma is a relatively rare hematologic malignancy that accounts for 10-20% of non-Hodgkin lymphomas. Treatment strategies for T-cell lymphomas are different from that for B-cell lymphomas and have poor prognoses. Among various subtypes of T-cell lymphomas, adult T-cell leukemia-lymphoma (ATL) has the worst prognosis. To achieve further improvement in the treatment outcome of T-cell lymphomas, several novel agents such as brentuximab vedotin, lenalidomide, romidepsin, and pralatrexate are actively being studied...
