Sauna therapy can act via two distinct mechanisms to raise the levels of BH4, acting in both cases by raising the levels of the enzyme GTP cyclohydrolase I (GPCH), the first and rate-limiting enzyme in the de novo synthesis pathway for BH4.
Sauna therapy acts to raise the biosynthesis of BH4 by raising the levels of GPCH, but that much of this BH4 can be subsequently oxidized to BH2 and biopterin, showing that there is still a lot of oxidative stress going on in these patients following sauna therapy.
GTP cyclohydrolase I (GPCH), in lymphocytes isolated from blood, was assayed by the method of Werner et al.
61), including that of biopterin, (Biop in the urine, columns 2 & 3), dihydrobiopterin (BH2, columns 4 & 5), tetrahydrobiopterin (BH4, columns 6 & 7), the enzyme GTP cyclohydrolase I in lymphocytes (GPCH, columns 8 & 9), 3-nitrotyrosine (3-NT, columns 10 & 11), and neopterin in the urine (Neo, columns 12 & 13).
Under inflammatory conditions, several inflammatory cytokines induce both the inducible nitric oxide synthase (iNOS; see Figure 1) and also GPCH, with the GPCH induction providing the increased BH4 needed to prevent widespread uncoupling of the iNOS enzyme.
A cette occasion, le GPCH a noue plusieurs partenariats dont la CNA -FEDERMODA en Italie, l'IKTIB en Turquie et maintenant avec l'expertise de la MMMM dans le domaine de la formation, de l'accompagnement et le soutien des jeunes createurs, le groupement visera a permettre aux laureats du Festival un meilleur rayonnement a l'international et a valoriser l'image du secteur du textile -habillement en Tunisie.
