Vascular endothelial growth factor (VEGF) is a major regulator of blood vessel formation during development and in the adult organism. Recent evidence indicates that this factor also plays an important role in sustaining the proliferation and differentiation of different cell types, including progenitor cells of different tissues, including bone marrow,(More)
BACKGROUND Active myocarditis is characterized by large heterogeneity of clinical presentation and evolution. This study describes the characteristics and the long-term evolution of a large sample of patients with biopsy-proven active myocarditis, looking for accessible and valid early predictors of long-term prognosis. METHODS AND RESULTS From 1981 to(More)
HIV-specific mucosal and cellular immunity was analyzed in heterosexual couples discordant for HIV status in serum and in HIV-unexposed controls. HIV-specific IgA but not IgG was present in urine and vaginal wash samples from HIV-exposed seronegative individuals (ESN), whereas both IgA and IgG were observed in their HIV-seropositive partners; antibodies(More)
Right ventricular dysplasia, a heart muscle disease of unknown cause, anatomically characterized by variable replacement of myocardial muscle with adipose or fibroadipose tissue, is usually considered a selective disorder of the right ventricle. However, concomitant left ventricular involvement has been noted in a few cases. The aim of this study was to(More)
OBJECTIVES The purpose of this study was to determine the prevalence of enteroviral infection in the myocardium of patients with idiopathic dilated cardiomyopathy by using a highly sensitive and specific detection technique. BACKGROUND Recent molecular studies have suggested that enteroviral persistence (in particular, coxsackieviruses type B) may(More)
Vectors based on the adeno-associated virus (AAV) deliver therapeutic genes to muscle and heart at high efficiency and maintain transgene expression for long periods of time. Here we report about the synergistic effect on blood vessel formation of AAV vectors expressing the 165 aa isoform of vascular endothelial growth factor (VEGF165), a powerful activator(More)
The presence and activity of human immunodeficiency virus (HIV)-specific antibodies were analyzed in the sera of 15 sexually exposed seronegative persons who had systemic HIV-specific cell-mediated immunity and IgA-mediated mucosal immunity and in their HIV-infected partners. The HIV-positive subjects had HIV-specific serum IgG and IgA; the seronegative(More)
The cytokines interleukin (IL)6 and IL10 appear to be involved in the progression of melanoma because they are secreted by malignant cells and their serum levels are associated with poor survival and with advanced stages of the disease. Antitumour immunity is considered to be a T-cell response, mediated mainly by type 1 cytokines such as IL12 and(More)
A case of acute advanced atrioventricular block in a young patient is described. An endomyocardial biopsy performed to confirm myocarditis showed findings compatible with rickettsial endomyocarditis. Treatment with tetracycline was therefore started and a rapid remission of the atrioventricular block was observed. Healing of the disease was subsequently(More)
Seminal to the process of arterial restenosis after balloon angioplasty is extracellular matrix degradation by metalloproteinases (MMPs); activity of these proteins is strongly inhibited by the tissue inhibitors of MMPs (TIMPs). Here we exploit gene transfer using an adeno-associated virus (AAV) for TIMP1 gene delivery in a rat model of intimal hyperplasia.(More)
