Peroxisomes carry out a diverse set of metabolic functions, including oxidation of very long-chain fatty acids, degradation of D-amino acids and hydrogen peroxide, and bile acid production. Many of these functions are upregulated on demand; therefore, cell ...
IntroductionDesulfitobacterium hafniense was isolated for its ability to use organohalogens as terminal electron acceptors via organohalide respiration (OHR). In contrast to obligate OHR bacteria, Desulfitobacterium spp. show a highly versatile energy meta ...
Recognition of pathogen-derived molecules through germline-encoded receptors is a fundamental principle of innate immunity. Pattern recognition receptors detect specific intracellular danger signals to trigger potent immune responses. The DNA sensor cyclic ...
Mitochondria, the main site of cellular energy harvesting, are derived from proteobacteria that evolved within our cells in endosymbiosis. Mitochondria retained vestiges of their proteobacterial genome, the circular mitochondrial DNA, which encodes 13 subu ...
Mitochondrial Ca2+ signals have been proposed to accelerate oxidative metabolism and ATP production to match Ca2+-activated energy-consuming processes. Efforts to understand the signaling role of mitochondrial Ca2+ have been hampered by the inability to ma ...
Functional neuroimaging has undergone spectacular developments in recent years. Paradoxically, its neurobiological bases have remained elusive, resulting in an intense debate around the cellular mechanisms taking place upon activation that could contribute ...
