Musculoskeletal abnormalities are common and multiple in diabetic patients. They often result from pathologic changes in the microvasculature (microangiopathy), connective tissue, and peripheral nerves related to chronic hyperglycaemia. Their prevalence in patients with diabetes vary depending upon the diagnostic criteria, the study population and is generally correlated with poor glycaemic control and the occurrence of other complications of diabetes. These entities are important to recognize because they often respond to treatment, preventing pain and disability and improving quality of life...

Marfan syndrome (MFS) is a connective tissue disorder, in which aortic rupture is the major cause of death. MFS patients with an aortic diameter below the advised limit for prophylactic surgery (<5cm) may unexpectedly experience an aortic dissection or rupture, despite yearly monitoring. Hence, there is a clear need for improved prognostic markers to predict such aortic events. We hypothesize that elastin fragments play a causal role in aortic calcification in MFS and that microcalcification serves as a marker for aortic disease severity...

The tumor-permissive and immunosuppressive characteristics of tumor-associated macrophages (TAM) have fueled interest in therapeutically targeting these cells. In this context, the colony-stimulating factor 1 (CSF1)/colony-stimulating factor 1 receptor (CSF1R) axis has gained the most attention, and various approaches targeting either the ligands or the receptor are currently in clinical development. Emerging data on the tolerability of CSF1/CSF1R-targeting agents suggest a favorable safety profile, making them attractive combination partners for both standard treatment modalities and immunotherapeutic agents...

Cartilage is a kind of special connective tissue which does not contain neither blood vessels nor lymphatics and nerves. Therefore, the damage in cartilage is difficult to be repaired spontaneously. Constructing tissue engineered cartilage provides a new technique for cartilage repairing. Mesenchymal stem cells (MSCs) possess a unique capability of self-renew and can differentiate into pre-chondrocytes which are frequently applied as seed cells in tissue engineering. However, in regenerated cartilage the chondrocytes derived from MSCs can hardly maintain homeostasis and preferentially present hypertrophic like phenotype...

This short insight covers some of the recent topics relevant to the field of cadherin-catenin adhesion in mediating connections between different cell types, so-called heterotypic or heterocellular connections, in both homeostasis and cancer. These scientific discoveries are increasing our understanding of how multiple cells residing in complex tissues can be instructed by cadherin adhesion receptors to regulate tissue architecture and function and how these cadherin-mediated heterocellular connections spur tumor growth and the acquisition of malignant characteristics in tumor cells...

The poly(ethylene glycol)-b-brush poly(l-lysine) polymer (PEG-b-(PELG50-g-PLL3)) was synthesized and evaluated as a nanocarrier for prolonging delivery of exenatide through the abdominal subcutaneous injection route. The isoelectric point of exenatide was 4.86, and exenatide could combine with PEG-b-(PELG50-g-PLL3) polymers via electrostatic interactions at pH 7.4. This polymer was a good candidate for achieving prolonged drug delivery for exenatide, considering its high molecular weight. Besides the physicochemical characterization of the polymer, in vitro and in vivo applications were researched as a sustained exenatide delivery system...

The transient receptor potential melastatin-3 (TRPM3) channel belongs to the family of transient receptor potential (TRP) cation channels that are expressed in a variety of tissues and cell types, including dorsal root ganglia, cardiomyocytes and pancreatic beta-cells. Although its natural ligands are currently unknown, TRPM3 channels can be activated by the neurosteroid pregnenolone sulfate, the synthetic ligand CIM0216, and by noxious heat. TRPM3 channels are regulated by phosphoinositides, and perhaps by calmodulin...

BACKGROUND/PURPOSE: Oral submucous fibrosis (OSF) is a premalignant condition caused by the chewing of areca nut (AN). Transforming growth factor β (TGFβ) plays a central role in the pathogenesis of OSF. Connective tissue growth factor (CTGF or CCN2) and early growth response-1 (Egr-1) are important mediators in the fibrotic response to TGFβ in several fibrotic disorders including OSF. Arecoline, a major AN alkaloid, induced the synthesis of CCN2 and Egr-1 in human buccal mucosal fibroblast (BMFs)...

BACKGROUND: Pulmonary artery aneurysms constitute <1% of aneurysms occurring in the thoracic cavity. Congenital cardiac defects are responsible for the majority (>50%) of cases, however, pulmonary artery aneurysm is a rare sequelae of pulmonary tuberculosis reported in about 5% of patients with chronic cavitary tuberculosis on autopsy. The natural history of this potentially fatal condition remains poorly understood and guidelines for optimal management are controversial. CASE PRESENTATION: A 24-year-old man, a nursing student of African descent, was referred to us from an up-country regional hospital with a 4-week history of recurrent episodes of breathlessness, awareness of heartbeats and coughing blood 3 weeks after completing a 6-month course of anti-tuberculosis drugs...

BACKGROUND: Calcified amorphous tumor of the heart is a rare, non-neoplastic cardiac mass characterized by nodular calcium in the background of amorphous degenerating fibrinous material. Clinical diagnosis of calcified amorphous tumor can be difficult, and current single imaging techniques do not specifically differentiate calcified amorphous tumor from other cardiac tumors such as calcified atrial myxoma, calcified thrombi, or vegetation. Complete surgical resection is the treatment of choice for both symptom improvement and prevention of embolization, as well as for pathological diagnosis...

Cells actively probe and respond to the stiffness of their surroundings. Since mechanosensory cells in connective tissue are surrounded by a disordered network of biopolymers, their in vivo mechanical environment can be extremely heterogeneous. Here we investigate how this heterogeneity impacts mechanosensing by modelling the cell as an idealized local stiffness sensor inside a disordered fibre network. For all types of networks we study, including experimentally-imaged collagen and fibrin architectures, we find that measurements applied at different points yield a strikingly broad range of local stiffnesses, spanning roughly two decades...

Distinction of chilblain lupus erythematosus (CLE) from idiopathic perniosis (IP) could predict an underlying connective tissue disease; however, histopathologic discrimination of the two is difficult. Increased CD123 plasmacytoid dendritic cells and CD30 lymphocytes have been demonstrated in various forms of cutaneous lupus erythematosus and IP, respectively. To our knowledge, CD123 and CD30 have not been examined in CLE. Our objective was to identify helpful histopathologic and immunohistochemical features in distinguishing CLE and IP...

Advanced colorectal cancer (CRC) remains a critical health care challenge worldwide. Various TGF-β superfamily members are important in colorectal cancer metastasis, but their signaling effects and predictive value have only been assessed in isolation. Here, we examine cross-regulation and combined functions of the two most prominent TGF-β superfamily members activin and TGF-β in advanced colorectal cancer. In two clinical cohorts we observed by immune-based assay that combined serum and tissue activin and TGF-β ligand levels predicts outcome in CRC patients and is superior to single ligand assessment...

Solitary fibrous tumours are a rare group of tumours that originate from connective tissues such as the pleura and mediastinum. When growing within the thoracic cavity these tumours exert pressure on vital organs and large vessels. We have successfully operated on two patients with large solitary fibrous tumours and managed the pathophysiological changes manifested as superior vena cava syndrome resulting from these tumours.

BACKGROUND: Low back pain causes more global disability than any other condition. Once the acute pain becomes chronic, about two-thirds of sufferers will not fully recover after 1-2 years. There is a paucity of effective treatments for non-specific, chronic low back pain. It has been noted that low back pain is associated with changes in the connective tissue in the affected area, and a very low-impact treatment, Esoteric Connective Tissue Therapy (ECTT), has been developed to restore flexibility in connective tissue...

BACKGROUND: Marfan syndrome is a genetic disease, presenting with dysfunction of connective tissues leading to lesions in the cardiovascular and skeletal muscle system. Within these symptoms, the most typical is weakness of the connective tissue in the aorta, manifesting as aortic dilatation (aneurysm). This could, in turn, become annuloaortic ectasia, or life-threatening dissection. As a result, life-saving and preventative cardiac surgical interventions are frequent among Marfan syndrome patients...
