There are currently several antibody therapies that directly target tumors, and antibody-drug conjugates represent a novel moiety as next generation therapeutics. Here, we used a unique screening probe, DT3C, to identify functional antibodies that recognized surface molecules and functional epitopes, and which provided toxin delivery capability. Accordingly, we generated the 90G4 antibody, which induced DT3C-dependent cytotoxicity in endothelial cells. Molecular analysis revealed that 90G4 recognized CD321, a protein localized at tight junctions...

The folate receptor (FR) has been established as a promising target for imaging and therapy of cancer (FR-α), inflammation, and autoimmune diseases (FR-β). Several folate-based PET radiotracers have been reported in the literature, but an 18F- labeled folate-PET imaging agent with optimal properties for clinical translation is still lacking. In the present study, we report the design and preclinical evaluation of folate-PEG12-NOTA-Al18F (1), a new folate-PET agent with improved potential for clinical applications...

Stroke is a leading cause of morbidity and mortality worldwide, and consists of two types, ischemic and hemorrhagic. Currently, there is no effective treatment to increase the survival rate or improve the quality of life after ischemic and hemorrhagic stroke in the subacute to chronic phases. Therefore, it is necessary to establish therapeutic strategies to facilitate functional recovery in patients with stroke during both phases. Cell-based therapies, using microglia and monocytes/macrophages preconditioned by optimal stimuli and/or any therapies targeting these cells, might be an ideal therapeutic strategy for managing stroke...

Juvenile idiopathic arthritis (JIA) is the most common cause of chronic arthritis in childhood. Up to 50% of patients are resistant to standard therapy, which includes non-steroid anti-inflammatory drugs, corticosteroids, disease-modifying anti-rheumatic drugs and biologic therapies. Intra-articular injection of mesenchymal stem cells (MSCs) is proposed as a new approach to JIA treatment. MSCs can modulate inflammation via mechanisms of both adaptive and innate immune response. They are able to inhibit T and B cell proliferation, promote regulatory T cells, suppress the maturation of dendritic cells, stimulate macrophage differentiation into M2 phenotype and reduce effectiveness of natural killer cells...

A single protein, HMGB1, directs the triggering of inflammation, innate and adaptive immune responses, and tissue healing after damage. HMGB1 is the best characterized damage-associated molecular pattern (DAMP), proteins that are normally inside the cell but are released after cell death, and allow the immune system to distinguish between antigens that are dangerous or not. Notably, cells undergoing severe stress actively secrete HMGB1 via a dedicated secretion pathway: HMGB1 is relocated from the nucleus to the cytoplasm and then to secretory lysosomes or directly to the extracellular space...

Tissue damage frequently occurs. The immune system senses it and enforces homeostatic responses that lead to regeneration and repair. The synthesis of acute phase molecules is emerging as a crucial event in this program. The prototypic long pentraxin PTX3 orchestrates the recruitment of leukocytes, stabilizes the provisional matrix in order to facilitate leukocyte and stem progenitor cells trafficking, promotes swift and safe clearance of dying cells and of autoantigens, limiting autoimmunity and protecting the vasculature...

BACKGROUND: Intrahepatic microvascular derangements and microcirculatory dysfunction are key in the development of liver cirrhosis and its associated complications. While much has been documented relating to cirrhosis and the dysfunction of the microcirculation in the liver parenchyma, far less is known about the state of the extrahepatic microcirculation and the role this may have in the pathogenesis of multiple organ failure in end stage liver cirrhosis. AIM: To provide an update on the role of the microcirculation in the pathophysiology of cirrhosis and its associated complications and briefly discuss some of the imaging techniques which may be used to directly investigate the microcirculation...

BACKGROUND: Tumor necrosis factor α (TNFα) blocking drugs are in use for a wide range of autoimmune disorders. In up to 5% of patients, this class of drugs produces puzzling cutaneous side effects that are the subject of this investigation, namely psoriasiform and eczema-like skin inflammation. These side effects can occur after any time of treatment and regardless of the underlying disorders. The exact pathophysiology is as yet unknown. METHODS: 33 patients (19 female, average age 52 years) who had a cutaneous reaction to infliximab, adalimumab or etanercept were included...

Hepatopulmonary syndrome (HPS) is a severe complication of cirrhosis with increased risk of mortality. Pulmonary microvascular alterations are key features of HPS, but underlying mechanisms are incompletely understood, and studies on HPS are limited to rats. Placental growth factor (PlGF), a pro-angiogenic molecule that is selectively involved in pathological angiogenesis, may play an important role in HPS development, however, its role has never been investigated. In this study, we validated an HPS model by common bile duct ligation (CBDL) in mice, investigated the kinetic changes in pulmonary angiogenesis and inflammation during HPS development, and provide evidence for a novel therapeutic strategy by targeting pathological angiogenesis...

Bilirubin acts as a potent endogenous antioxidant, with higher concentrations associated with lower rates of CVD; the antiretroviral drug atazanavir (ATV) increases bilirubin levels but may also increase von Willebrand factor levels. We tested the hypothesis that increasing endogenous bilirubin using ATV would improve cardiometabolic risk factors and vascular function in older patients with HIV. Ninety participants were enrolled in two study protocols. In protocol 1, we evaluated markers of inflammation, thrombosis, and conduit artery endothelial function in subjects on non-ATV containing regimens...

Obesity and type 2-diabetes are becoming a worldwide health problem, reiterating the importance of alternative therapies to tackle their progression. Here, we hypothesized that supplementation of diet with 6% w/w of a freeze-dried strawberry-blueberry (5 : 1) powder (FDSB) could exert beneficial metabolic effects on Wistar rats. FDSB-supplemented animals experienced significantly reduced body weight gain, food efficiency and visceral adiposity accumulation in two independent experiments. FDSB supplementation also contributed to lower area under the curve after an intraperitoneal GTT and reduced serum insulin levels and an insulin resistance index (IR-HOMA) in HFS diet-fed animals, together with reduced plasma MCP-1 inflammation marker concentrations...

MicroRNA miR-34a is recognized as a master regulator of tumor suppression. The strategy of miR-34a replacement has been investigated in clinical trials as the first attempt of miRNA application in cancer treatment. However, emerging outcomes promote the re-evaluation of existing knowledge and urge the need for better understanding the complex biological role of miR-34a. The targets of miR-34a encompass numerous regulators of cancer cell proliferation, survival and resistance to therapy. MiR-34a expression is transcriptionally controlled by p53, a crucial tumor suppressor pathway, often disrupted in cancer...

BACKGROUND: Preterm birth (PTB) is a multifactorial syndrome occurring before the 37th week of full-term pregnancy [1]. Babies delivered preterm experience short-term and long-term complications affecting multiple organ systems, and serious maternal complications include hemorrhage and infection. Each year, an estimated 15 million babies are born preterm, and complications from prematurity are the leading cause of death among children up to 5 years of age [2]. With another increase in PTB rates over the last several years, the United States continues to have the highest incidence of any industrialized country [3]...
