One of the most characteristic clinical features in cutaneous leishmaniasis is the development of nodules followed by ulcerations at the site of infection. Leishmania amazonensis-infected mice show similar ulcerative lesions. Leishmania-infected severe combined immunodeficiency (SCID) mice, however, have been shown to develop nonulcerative nodules. In the present study, the roles of T cells in ...
To better understand the peculiar functional behavior of engrafted maternal T cells in a severe combined immunodeficiency (SCID) patient, we characterized, at the molecular level, the T-cell repertoire of a SCID child with a high number of engrafted, mature, activated lymphocytes. We found that, although these transplacentally acquired T cells express a random set of T-cell receptor variable be...
Patients with Omenn syndrome (OS) have hypomorphic RAG mutations and develop varying manifestations of severe combined immunodeficiency. It is not known which symptoms are caused directly by the RAG mutations and which depend on other polymorphic genes. Our current understanding of OS is limited by the lack of an animal model. In the present study, we identified a C57BL/10 mouse with a spontane...
Early diagnosis of severe combined immunodeficiency (SCID) is important to enable prompt referral to a supraregional centre for bone marrow transplantation before the occurrence of end organ damage secondary to infective complications. This review outlines clinical, microbiological, and immunopathological clues that aid the diagnosis of SCID and emphasises the multidisciplinary approach needed ...
Despite the first application of gene therapy in 1990, gene therapy has until recently failed to meet the huge expectations set forth by researchers, clinicians, and patients, thus dampening enthusiasm for an imminent cure for many life-threatening genetic diseases. Nonetheless, in recent years we have witnessed a strong comeback for gene therapy, with clinical successes in young and adult subj...
To characterize thymic epithelial cells of SCID (severe combined immunodeficiency) mice in comparison with those of Balb C mice, we did an immunohistochemical study using cortical and medullary epithelial cell specific monoclonal antibodies (MoAbs), Th-3 and Th-4, as well as gel electrophoresis and immunoblotting. The thymi of SCID mice were composed of epithelial cells and a few lymphocytes. M...
Bacille Calmette-Guerin (BCG) vaccine is administered to all newborns in countries where tuberculosis is still endemic. It is a live attenuated vaccine and considered quite safe in immunocompetent children. Disseminated BCG disease is the most serious complication seen only in individuals with underlying primary or secondary immunodeficiencies. We report a case of disseminated BCG disease in an...
The benefits and risks of bacille Calmette-Guerin vaccination among infants at high risk for both Title: tuberculosis and severe combined immunodeficiency: assessment by Markov model
BACKGROUND Oral poliovirus vaccine (OPV) has not been used in the United States since 2000. Type 1 vaccine-derived poliovirus (VDPV) was identified in September 2005, from an unvaccinated Amish infant hospitalized in Minnesota with severe combined immunodeficiency. An investigation was conducted to determine the source of the virus and its means of transmission. METHODS The infant was tested ...
