Dietary protection against the visual and motor deficits induced by experimental autoimmune encephalomyelitis.

Introduction: Five to eight percent of the world population currently suffers from at least one autoimmune disorder. Despite multiple immune modulatory therapies for autoimmune demyelinating diseases of the central nervous system, these treatments can be limiting for subsets of patients due to adverse effects and expense. To circumvent these barriers, we investigated a nutritional intervention in mice undergoing experimental autoimmune encephalomyelitis (EAE), a model of autoimmune-mediated demyelination that induces visual and motor pathologies similar to those experienced by people with multiple sclerosis (MS).

Sperm very long-chain polyunsaturated fatty acids: relation to semen parameters and live birth outcome in a multicenter trial.

Objective: To determine whether the levels of sperm very long-chain polyunsaturated fatty acids (VLC-PUFAs) are correlated with sperm parameters and the outcome of live birth after conventional therapy for unexplained infertility.

Design: Cohort analysis of the Reproductive Medicine Network's Assessment of Multiple Intrauterine Gestations from Ovarian Stimulation randomized controlled trial.

Setting: Multicenter randomized controlled trial.

Transmembrane protein 135 regulates lipid homeostasis through its role in peroxisomal DHA metabolism.

Transmembrane protein 135 (TMEM135) is thought to participate in the cellular response to increased intracellular lipids yet no defined molecular function for TMEM135 in lipid metabolism has been identified. In this study, we performed a lipid analysis of tissues from Tmem135 mutant mice and found striking reductions of docosahexaenoic acid (DHA) across all Tmem135 mutant tissues, indicating a role of TMEM135 in the production of DHA. Since all enzymes required for DHA synthesis remain intact in Tmem135 mutant mice, we hypothesized that TMEM135 is involved in the export of DHA from peroxisomes.
