Ming-Sing Si, Richard G Ohye
In specific forms of congenital heart defects and pulmonary hypertension, the right ventricle (RV) is exposed to systemic levels of pressure overload. The RV is prone to failure in these patients because of its vulnerability to chronic pressure overload. As patients with a systemic RV reach adulthood, an emerging epidemic of RV failure has become evident. Medical therapies proven for LV failure are ineffective in treating RV failure. Areas covered: In this review, the pathophysiology of the failing RV under pressure overload is discussed, with specific emphasis on the pivotal roles of angiogenesis and oxidative stress...

BACKGROUND: Oxidative stress-induced mitochondrial dysfunction may contribute to inflammation and remodeling in chronic obstructive pulmonary disease (COPD). Mesenchymal stem cells (MSCs) protect against lung damage in animal models of COPD. It is unknown whether these effects occur through attenuating mitochondrial dysfunction in airway cells. OBJECTIVE: To examine the effect of induced-pluripotent stem cell-derived MSCs (iPSC-MSCs) on oxidative stress-induce mitochondrial dysfunction in human airway smooth muscle cells (ASMCs) in vitro and in mouse lungs in vivo...

PURPOSE: Rituximab is an anti-CD20 monoclonal antibody that is used to suppress B-cell function in graft-versus-host-disease (GVHD). We sought to determine the effects of rituximab treatment on lung function in those patients with bronchiolitis obliterans syndrome (BOS) as a manifestation of GVHD. METHODS: Thirteen patients were treated with rituximab with a diagnosis of BOS and a significant reduction in the forced expiratory volume in 1 s (FEV1) after hematopoietic stem cell transplantation (HSCT)...

OBJECTIVE: Late-onset non-infectious pulmonary complications (LONIPCs) contribute to higher morbidity and mortality after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Therefore, we investigated the risk factors of LONIPCs in pediatric patients. METHOD: Between 2001 and 2011, 74 pediatric patients (range, 7 months to 22.7 years old; median 6.5 years old), including 29 with a primary immunodeficiency underwent 80 allo-HSCTs at our institution. Sixty-seven patients who survived more than 3 months after allo-HSCT were analyzed retrospectively...

Human bone marrow derived mesenchymal stem cells (BM-MSCs) resides in their niches in close proximity to hematopoietic stem cells (HSCs). These naïve MSCs have tremendous potential in regenerative therapeutics, and may also be exploited by cancer and infectious disease agents. Hence, it is important to study the physiological and pathological roles of naïve MSC. However, our knowledge of naïve MSCs is limited by lack of appropriate isolation and in vitro culture methods. Established culture methods use serum rich media, and serial passaging for retrospective isolation of MSCs...

BACKGROUND: Late-onset noninfectious pulmonary complications (LONIPCs), which occur more than 3 months after allogeneic hematopoietic stem cell transplantation (HSCT), are major causes of morbidity and mortality after transplantation. Among LONIPCs, we occasionally treat patients with late-onset severe restrictive lung defect after HSCT; however, its clinical features have not been fully elucidated. METHODS: A retrospective chart review of a single center on cases of late-onset severe restrictive lung defect after HSCT was performed...

End-stage lung disease is the third leading cause of death worldwide, accounting for 400,000 deaths per year in the United States alone. To reduce the morbidity and mortality associated with lung disease, new therapeutic strategies aimed at promoting lung repair and increasing the number of donor lungs available for transplantation are being explored. Because of the extreme complexity of this organ, previous attempts at bioengineering functional lungs from fully decellularized or synthetic scaffolds lacking functional vasculature have been largely unsuccessful...

The development of radiation-induced pulmonary fibrosis represents a critical clinical issue limiting delivery of therapeutic doses of radiation to non-small cell lung cancer. Identification of the cell types whose injury initiates a fibrotic response and the underlying biological factors that govern that response are needed for developing strategies that prevent or mitigate fibrosis. C57BL/6 mice (wild type, Nrf2 null, Nrf2(flox/flox), and Nrf2(Δ/Δ); SPC-Cre) were administered a thoracic dose of 12Gy and allowed to recover for 250 days...

Pulmonary vein leiomyosarcoma is extremely rare and has a poor prognosis. Surgical resection with a wide margin seems to offer the only chance of cure. The role of adjuvant therapy is controversial, and the exact efficacy of chemotherapy has not been observed. In this report, we present an 18-year-old male patient with pulmonary vein leiomyosarcoma in whom the use of paclitaxel (PAX) proved to be effective. Because the tumor originated from the left superior pulmonary vein and diffused into the left atrial wall and the junction of the right superior pulmonary vein and left atrium, the en bloc excision of the tumor was impossible...

The kidney is the most common organ affected by immunoglobulin light-chain (AL) amyloidosis and monoclonal immunoglobulin deposition disease (MIDD), often leading to end stage renal disease (ESRD). High-dose melphalan and stem cell transplantation (HDM/SCT) is effective for selected patients with AL amyloidosis, with high rates of complete hematologic responses and potential for improvement in organ dysfunction. Data on tolerability and response to HDM/SCT in patients with ESRD due to AL amyloidosis and MIDD are limited...

The survival rate of preterm neonates increases significantly with the development of neonatal care and comprehensive treatment, but more and more high-risk preterm neonates suffer from bronchopulmonary dysplasia (BPD). Currently, there is no effective treatment for BPD, thus it is still a major cause of disability and mortality in neonates. Thus, it is imperative to investigate the pathogenesis and treatment of BPD in depth. Fibroblast growth factor-10 (FGF-10) is a paracrine growth factor binding its receptors (FGFR1 and FGFR2) to regulate a lot of biological processes...

Biomarkers of heart failure in adults have been extensively studied. However, biomarkers to monitor the progression of heart failure in children with univentricular physiology are less well understood. We proposed that as mediators of diverse pathophysiology, miRNAs contained within circulating microvesicles could serve as biomarkers for the presence and progression of heart failure in univentricular patients. To test this, we studied the association of heart failure with elevations in specific miRNAs isolated from circulating microvesicles in a cohort of children with univentricular heart disease and heart failure...

Myeloid cells, including monocytes and macrophages participate in steady state immune homeostasis and help mount the adaptive immune response during infection. The function and production of these cells in sterile inflammation, such as pulmonary hypertension (PH), is understudied. Emerging data indicate that pulmonary inflammation mediated by lung perivascular macrophages is a key pathogenic driver of pulmonary remodeling leading to increased right ventricular systolic pressure (RVSP). However, the origin of these macrophages in pulmonary inflammation is unknown...

RATIONALE: Mesenchymal stem/stromal cell (MSC) therapies have shown promise in preclinical models of pathologies relevant to newborn medicine, such as bronchopulmonary dysplasia (BPD). We have reported that the therapeutic capacity of MSCs is comprised in their secretome, and demonstrated that the therapeutic vectors are exosomes produced by MSCs (MSC-exos). OBJECTIVE: To assess efficacy of MSC-exo treatment in a pre-clinical model of BPD and to investigate mechanisms underlying MSC-exo therapeutic action...

Prostacyclin (prostaglandin I2, PGI2) over-production in FVB/N mice prevents the formation of carcinogen and tobacco smoke induced adenomas, and administration of the oral prostacyclin analog iloprost to wild type mice also prevented carcinogen-induced mouse lung adenoma formation. Former smokers taking oral iloprost showed improved bronchial dysplasia histology compared to placebo. Next generation oral prostacyclin analogues, like treprostinil, were developed for treatment of pulmonary arterial hypertension (PAH)...

In the last years, significant progress has been made in the clinical follow-up of leukemia patients who are especially prone to various infections because of the specific immunosuppressive state following chemotherapy. The follow-up of such patients is of special interest and is based on modern imaging protocols especially computer tomography (CT). Still, CT may not always be effective in the diagnosing of respiratory infections. We report a chronic lymphocytic leukemia patient in which the pleuro-pulmonary complications were successfully diagnosed and followed up using transthoracic ultrasonography...

The amniotic fluid is a clinically accessible source of mesenchymal stem cells (AF-MSC) during gestation, which enables autologous cellular therapy for perinatal disorders. The origin of AF-MSC remains elusive: renal and neuronal progenitors have been isolated from the AF-MSC pool, yet no cells with pulmonary characteristics. We analyzed gene expression of pulmonary and renal markers of 212 clonal lines of AF-MSC isolated from amniocentesis samples. AF-MSC were cultured on dishes coated with extracellular matrix (ECM) proteins from decellularized fetal rabbit lungs...

Pulmonary diseases cusecs a large portion of mortality in the world. There is no more cure for pulmonary diseases and many approaches are needed for finding ways to cure. Nowadays, implantation and drugs are only ways for curing those people who are facing with these diseases. Tissue engineering and regenerative medicine have been appeared as multidisciplinary field and also, they presents new therapeutic approaches for pulmonary diseases. One of these therapeutic approaches is decellularization which removes cellular but leaves intact important extracellular matrix (ECM) proteins and three-dimensional (3D) architecture and also, this approach has been studied for in-vitro and ex-vivo...

Radiation-induced pulmonary fibrosis (RIPF) is a debilitating side effect that occurs in up to 30% of thoracic irradiations in breast and lung cancer patients. RIPF remains a major limiting factor to dose escalation and an obstacle to applying more promising new treatments for cancer cure. Limited treatment options are available to mitigate RIPF once it occurs, but recently, mesenchymal stem cells (MSCs) and a drug treatment stimulating endogenous stem cells (GM-CSF) have been investigated for their potential in preventing this disease onset...

Lymphangioleiomyomatosis (LAM) is a progressive destructive neoplasm of the lung associated with inactivating mutations in the TSC1 or TSC2 tumor suppressor genes. Cell or animal models that accurately reflect the pathology of LAM have been challenging to develop. Here we generated a robust human cell model of LAM by reprogramming TSC2 mutation-bearing fibroblasts from a patient with both Tuberous Sclerosis Complex (TSC) and LAM (TSC-LAM) into induced pluripotent stem cells (iPSCs), followed by selection of cells that resemble those found in LAM tumors by unbiased in vivo differentiation...
