(author), van Loveren, H. (author), TNO Kwaliteit van Leven (author)Current developmental and reproductive toxicity protocols include only a limited set of parameters for effects on the developing immune system. In this study, a wide range of immunological parameters were included in a pre- and postnatal developmental toxicity study. Dose-response data were compared to determine the relative sensitivity of...article 2010

(author), TNO Kwaliteit van Leven (author)Background: The development of global tests for the fibrinolytic capacity in blood is hampered by the low base-line fibrinolytic activity in blood, by the involvement of both plasmatic components and blood cells in the fibrinolytic system and by the loss of fibrinolytic activity as a result of the action of plasminogen activator inhibitor-1 (PAI...article 2008

(author), TNO Kwaliteit van Leven (author)Background: Coeliac disease is caused by an immune response to gluten. As gluten proteins are proline rich they are resistant to enzymatic digestion in the gastrointestinal tract, a property that probably contributes to the immunogenic nature of gluten. Aims: This study determined the efficiency of gluten degradation by a post-proline cutting...article 2008

(author), Masereeuw, R. (author), TNO Kwaliteit van Leven (author)The multidrug resistance gene 1 product, P-glycoprotein (P-gp), is expressed in several excretory organs, including the apical membrane of proximal tubules. After inducing acute renal failure, P-gp expression is upregulated and this might be a protective function by pumping out toxicants and harmful products of oxidative stress. We characterized...article 2007

(author), Knulst, A.C. (author), Knol, E.F. (author), TNO Kwaliteit van Leven (author)Background: In peanut-allergic adults, IgE is mainly directed to Ara h1 and Ara h2. More recently, a role for Ara h6 has been suggested. In contrast to adults, IgE in children can fluctuate over time. Therefore, children may have a more dynamic reactivity to peanut. Objective: To examine the IgE reactivity to major peanut allergens in peanut...article 2007
