Shankar, K. (author), Pivik, R.T. (author), Johnson, S.L. (author), van Ommen, B. (author), Demmer, E. (author), Murray, R. (author)Understanding health requires more than knowledge of the genome. Environmental factors regulate gene function through epigenetics. Collectively, environmental exposures have been called the "exposome." Caregivers are instrumental in shaping exposures in a child's initial years. Maternal dietary patterns, physical activity, degree of weight gain,...article 2018

(author), TNO Kwaliteit van Leven (author)Toll-like receptors (TLRs) are innate immunity receptors that are expressed on a wide range of cell types, including CNS glial cells. In general, TLR engagement by specific sets of microbial ligands triggers production of pro-inflammatory factors and enhances antigen-presenting cell functions. The functional roles of TLR in the CNS, however, are...article 2006
