Immune Stimulation of Interferon-Gamma- and Biopterin Synthesis with Endotoxin in Animal-Experimental Peritonitis [PDF]

Pteridines, 1993
As a result to a microhial stimulus different defence systems are activated. Bacterial lipopolysaccharids (endotoxins) can lead to activation of the immune system in which phagocytic cells like macrophages.

Tetrahydrobiopterin, responsive, hyperphenylalaninemia without biopterin defiCIency

Pteridines, 2000
Hyperphenylalaninemia (HPA) results from a deficiency of the enzyme phenylalanine hydroxylase (PAH) or of its cofactor, tetrahydrobiopterin (BH4). In 1999, Kure et al reported that some patients with PAH deficiency showed lowering of blood Phe levels after BH4 loading (1). We found several patients with HPA whose serum phenylalanine levels decreased at

Biopterin responsive phenylalanine hydroxylase deficiency [PDF]

Genetics in Medicine, 2004
Phenylketonuria (PKU) is an autosomal recessive disorder caused by mutations in the phenylalanine hydroxylase (PAH) gene. There have been more than 400 mutations identified in the PAH gene leading to variable degrees of deficiency in PAH activity, and consequently a wide spectrum of clinical severity.
