Ann-Kathrin Lederer,Luciana Hannibal,Manuel Hettich,Sidney Behringer,Ute Spiekerkoetter,Carmen Steinborn,Carsten Gründemann,Amy Marisa Zimmermann-Klemd,Alexander Müller,Thomas Simmet,Michael Schmiech,Andrea Maul-Pavicic,Yvonne Samstag,Roman Huber +13 more
TL;DR: Plasma holo-TC may be a fast-responding biomarker to monitor adequate supply of vitamin B12 in plant-based individuals to reduce the risk of micronutrient deficiencies in Vegans.
Journal ArticleDOI
Vegan diet reduces neutrophils, monocytes and platelets related to branched-chain amino acids - A randomized, controlled trial.
Ann-Kathrin Lederer,Andrea Maul-Pavicic,Luciana Hannibal,Manuel Hettich,Carmen Steinborn,Carsten Gründemann,Amy Marisa Zimmermann-Klemd,Alexander Müller,Bettina Sehnert,Ulrich Salzer,Reinhild Klein,Reinhard E. Voll,Yvonne Samstag,Roman Huber +13 more
TL;DR: Four weeks of a controlled VD affected the number of neutrophils, monocytes and platelets but not the number or function of lymphocytes, and the relation with branched-chain amino acids and GM-CSF suggests a mode of action via the mTOR signaling pathway.
Journal ArticleDOI
A Vegan Diet Is Associated with a Significant Reduction in Dietary Acid Load: Post Hoc Analysis of a Randomized Controlled Trial in Healthy Individuals
Alexander Müller,Amy Marisa Zimmermann-Klemd,Ann-Kathrin Lederer,Luciana Hannibal,Stefanie Kowarschik,Roman Huber,Maximilian Andreas Storz +6 more
TL;DR: In this paper, a randomized controlled trial was conducted to examine whether an isocaloric vegan diet lowers dietary acid load (DAL) as compared to a meat-rich diet, which was determined using potential renal acid load and net endogenous acid production (NEAP) scores at baseline and after 3 and 4 weeks.
Journal ArticleDOI
Immunosuppressive Activity of Artemisia argyi Extract and Isolated Compounds
Amy Marisa Zimmermann-Klemd,Jakob K. Reinhardt,Anna Morath,Wolfgang W. A. Schamel,Peter Steinberger,Judith Leitner,Roman Huber,Matthias Hamburger,Carsten Gründemann +8 more
TL;DR: Investigation of the T cell proliferation inhibitory potential of an extract library of plants used in traditional Chinese medicine found that an ethyl acetate extract of Artemisia argyi was found to suppress the proliferation of human primary T lymphocytes in vitro in an IL-2-dependent manner.
Journal ArticleDOI
Boswellia carteri extract and 3-O-acetyl-alpha-boswellic acid suppress T cell function.
Amy Marisa Zimmermann-Klemd,Jakob K. Reinhardt,Thanasan Nilsu,Anna Morath,Chiara Madlen Falanga,Wolfgang W. A. Schamel,Roman Huber,Matthias Hamburger,Carsten Gründemann +8 more
TL;DR: Transcription factor analysis showed that the immunosuppressive effects of the extract are based on specific NFAT-conditioned suppression within T cell signaling, and 3-O-acetyl-alpha-boswellic acid was identified as the compound responsible for theNFAT-based mechanism.
