SCOPE: Mushrooms are valued as an edible and medical resource for millennia. As macrofungi, they possess conserved molecular components recognized by innate immune cells like macrophages, yet unlike pathogenic fungi, they do not trigger the immune system in the same way. That these well-tolerated foods both avoid immuno-surveillance and have positive health benefits, highlights the dearth of information on the interactions of mushroom-derived products with our immune system. METHODS & RESULTS: Using powders produced from the common white button mushroom, Agaricus bisporus, it was observed that pre-treatment of mouse and human macrophages with mushroom powders attenuates innate immune signalling triggered by microbial ligands like LPS and  β-glucans, including NFκB activation and pro-inflammatory cytokine production...

SCOPE: A range of health benefits are attributed to consuming urolithin A (UA), such as improved muscle health, anti-aging activity and neuroprotection, whereas few studies raise possible adverse effects at high doses, including genotoxicity and estrogenic effects. Therefore, understanding UA bioactivity and safety depends on its pharmacokinetics. However, there is no physiologically-based pharmacokinetic (PBPK) model available for UA, thus limiting reliable assessment of effects observed from in vitro experimentation...

SCOPE: The aging biomarkers are alternatives and none of them could act as a strong predictor of frailty during the progression of aging. Several studies revealed the relationship between metabolites and frailty or gut microbiota and frailty. However, the connection between metabolites and gut microbiota in non-robust older adults hasn't been discussed yet. Our study aims to combine the findings of serum metabolites and gut microbiota in non-robust subjects as a possible diagnostic biomarker...

SCOPE: Zinc is important for a balanced immune system, but the mechanisms are not yet fully elucidated. One possibility is an interaction of zinc with the tricarbocylic acid cycle (TCA), in which zinc inhibits the mitochondrial aconitase leading to an increase in intracellular citrate concentration as described for prostate cells. Therefore, we studied the immune modulatory effects of zinc and citrate and their interaction in mixed lymphocyte cultures (MLC). METHODS AND RESULTS: After allogeneic (MLC) or superantigen stimulation, the interferon-γ (IFNγ) production was quantified by ELISA and T cell subpopulations were determined by Western Blot...
