There is little evidence regarding the maintenance of long-term clinical remission by adalimumab (ADA) therapy in Crohn's disease (CD) patients naïve to anti-tumor necrosis factor treatment (naïve CD patients), since most CD patients are treated with ADA after infliximab (IFX) therapy. The long-term clinical response to ADA was retrospectively analyzed in 17 naïve CD patients for at least 24 mo...
Adenosine deaminase (ADA) deficiency in humans results in a severe combined immunodeficiency (SCID). This immunodeficiency is associated with severe disturbances in purine metabolism that are thought to mediate lymphotoxicity. The recent generation of ADA-deficient (ADA(-/-)) mice has enabled the in vivo examination of mechanisms that may underlie the SCID resulting from ADA deficiency. We demo...
Concurrency introduces a high degree of combinatory which may be the source of subtle mistakes. We present a new tool, Quasar, which is based on ASIS and which uses fully the concept of patterns. The analysis of a concurrent Ada program by our tool proceeds in four steps: automatic extraction of the concurrent part of the program; translation of the simplified program into a formal model using ...
Antibodies against biopharmaceuticals (anti-drug antibodies, ADA) have been a well-integrated part of the clinical care of multiple sclerosis (MS) in several European countries. ADA data generated in Europe during the more than 10 years of ADA monitoring in MS patients treated with interferon beta (IFNβ) and natalizumab have been pooled and characterized through collaboration within a European ...
We have investigated the structural gene for adenosine deaminase (ADA) in a female infant with ADA deficiency associated severe combined immune deficiency (ADA-SCID) disease and her family by DNA restriction-fragment-length analysis. In this family a new ADA-specific restriction-fragment-length variant was detected, which involves a 3.2-kb deletion spanning the ADA promoter as well as the first...
also suggest that early initiation of PEG-ADA should be considered for ADA-deficient patients suffering from PAP, particularly when rapid hematopoietic stem cell transplantation cannot be performed. Our study also has several significant limitations. While we focused on AMs, future studies are needed to assess the role of pneumocytes and other lung cell abnormalities in the development of PAP i...
Human adenosine deaminase (ADA; adenosine aminohydrolase, EC 3.5.4.4) was expressed at high levels in cultured mouse cells using a transmissable murine retrovirus vector system. A cDNA clone encoding ADA has been inserted into a plasmid vector containing retroviral transcription and packaging signals as well as a selectable gene for G418 resistance. The constructions were transfected into psi 2...
Adenosine acts as anti-inflammatory mediator on the immune system and has been described in regulatory T cell (Treg)-mediated suppression. In the absence of adenosine deaminase (ADA), adenosine and other purine metabolites accumulate, leading to severe immunodeficiency with recurrent infections (ADA-SCID). Particularly ADA-deficient patients with late-onset forms and after enzyme replacement th...
Extracellular levels of adenosine increase during hypoxia. While acute increases in adenosine are important to counterbalance excessive inflammation or vascular leakage, chronically elevated adenosine levels may be toxic. Thus, we reasoned that clearance mechanisms might exist to offset deleterious influences of chronically elevated adenosine. Guided by microarray results revealing induction of...
Adenosine deaminase (ADA) was detected immunohistochemically in neuronal cell bodies of dorsal root ganglia (DRG) of the rat. ADA-immunoreactivity was confined exclusively to small type B ganglion neurons in cervical, thoracic and lumbar sensory ganglia; large type A neurons in sensory ganglia were devoid of immunostaining for ADA. It was consistently found that only a small proportion of type ...
