The levels of adenosine deaminase (ADA) were determined in the erythrocytes of 10 patients with sexually transmitted HIV-1 infection [five cases with AIDS-related complex (ARC) and five with AIDS] before and after therapy with zidovudine (azidothymidine; AZT). A linear increase in ADA activity was
Adenosine deaminase (ADA), an enzyme involved in purine metabolism, has been shown to be of clinical importance in several diseases in humans. To investigate whether ADA is of any clinical significance in cats, plasma adenosine deaminase (P-ADA) and T cell adenosine deaminase (T-ADA) activities were
The purine metabolic enzymes adenosine deaminase (ADA), purine nucleoside phosphorylase (PNP), and 5'nucleotidase (5NT) have been shown to be important for normal lymphocyte maturation. Abnormalities of these enzymes have been associated with hereditary as well as acquired immunodeficiency states.
The association between human immunodeficiency virus type I (HIV-I) infection and high levels of erythrocyte adenosine deaminase (ADA) has been suggested by Cowan et al [1986]. We have analyzed the specific activities of the same enzyme during different stages of acquired immunodeficiency syndrome
The levels of purine enzyme activities were studied in 10 patients with acquired immunodeficiency syndrome (AIDS) or AIDS related complex (ARC) and in 6 healthy individuals with antibodies against human immunodeficiency virus (HIV). All AIDS/ARC patients studied had ecto-5'nucleotidase (ecto-5'NUC)
It is hypothesized that SIDS mimics AIDS and atopic eczema in that defective T lymphocytes and overactive B cells overstimulate pro-inflammatory cytokines in the mucosal immune system. Virally infected cells are unable to convert linoleic acid (LA) into gamma-linolenic acid (GLA) which eventually
Restoration of immune functions through promoting cell cycle might delay acquired immunodeficiency syndrome development. Therefore, stimulation of peripheral lymphocytes of human immunodeficiency virus-1 infected patients in successive clinical stages was studied by phytohaemagglutinin and other
