Experiments in vitro were made to study adenosine deaminase (ADA) and
5'-nucleotidase
(5-N) activity in NK after their treatment with interferon inductor--
Newcastle disease
virus (NDV) or with prostaglandin E2 (PGE2). It has been established that treatment of human NK with NDV leads to increasing of their cytotoxic activity (CTA), which is accompanied by rising of ADA activity and reducing of 5-N activity in these cells. Decrease of CTA under the influence of PGE2 occurs together with reduction of ADA activity and increase of 5-N activity in human NK. Changes in NK activity under the influence of various exogenous or endogenous factors may be due to the modification of activity of adenosine metabolism enzymes in these cells.

Newcastle disease
virus (NDV) has received much attention recently because of its non-specific immune stimulating potential and its various anti-tumor activities. Here we describe that NDV induces synthesis of NO and causes an activation of nuclear factor-kappa B (NF-kappa B) in murine macrophages. These reactions were part of an activation process which included also stimulation of adenosine deaminase and inhibition of
5'-nucleotidase
. NDV-mediated NO synthesis and NF-kappa B activation were blocked by an antioxidant (butylated hydroxyanisole), by an inhibitor of protein tyrosine kinase (genistein) and of protein kinase A (H-89), but not by an inhibitor of protein kinase C (staurosporin). These data suggest that signalling requirements of NF-kappa B activation and NO production in NDV-treated macrophages are similar.
