Highlights•Tissue-resident, SFB-elicited Th17 cells are non-inflammatory•Citrobacter-elicited show high plasticity towards inflammatory cytokines•SFB metabolically similar to resting memory cells•Citrobacter highly glycolytic effector cellsSummaryT helper 17 (Th17) pathogenic in many diseases, but also support the integrity of intestinal barrier a non-inflammatory manner. It is unclear what distinguishes elicited by pathogens and tissue-resident homeostatic commensals. Here, we compared characteristics differentiating response commensal bacteria (SFB) those pathogen (Citrobacter rodentium). Homeostatic exhibited little expression cytokines, were characterized metabolism typical quiescent or T cells, did not participate processes. In contrast, infection-induced showed extensive pro-inflammatory disseminated widely into periphery, engaged aerobic glycolysis addition oxidative phosphorylation for cells. These findings will help ensure that future therapies directed against do inadvertently damage resident gut population.Graphical abstract

Mitochondria are highly dynamic organelles undergoing coordinated cycles of fission and fusion, referred as ‘mitochondrial dynamics’, in order to maintain their shape, distribution size. Their transient rapid morphological adaptations crucial for many cellular processes such cell cycle, immunity, apoptosis mitochondrial quality control. Mutations the core machinery components defects dynamics have been associated with numerous human diseases. These transitions mainly ensured by large GTPases belonging Dynamin family. Mitochondrial is a multi-step process allowing division one mitochondrion two daughter mitochondria. It regulated recruitment GTPase Dynamin-related protein 1 (Drp1) adaptors at actin- endoplasmic reticulum-mediated constriction sites. Drp1 oligomerization followed leads 2 terminate membrane scission. Inner has proposed be an independent calcium influx. fusion driven two-step outer mediated mitofusins inner optic atrophy 1. In addition role lipid composition, several members can undergo post-translational modifications modulating these processes. Understanding molecular mechanisms controlling decipher how shape meets function increase knowledge on basis diseases morphology defects. This article will describe overview that govern mammals.

Abstract Alzheimer’s disease (AD) is a neurodegenerative characterized by progressive memory loss along with neuropsychiatric symptoms and decline in activities of daily life. Its main pathological features are cerebral atrophy, amyloid plaques, neurofibrillary tangles the brains patients. There various descriptive hypotheses regarding causes AD, including cholinergic hypothesis, tau propagation mitochondrial cascade calcium homeostasis neurovascular inflammatory metal ion lymphatic system hypothesis. However, ultimate etiology AD remains obscure. In this review, we discuss related clinical trials. Wealthy puzzles lessons have made it possible to develop explanatory theories identify potential strategies for therapeutic interventions AD.

Mitochondria are organelles with a highly dynamic ultrastructure maintained by delicate equilibrium between its fission and fusion rates. Understanding the factors influencing this balance is important as perturbations to mitochondrial dynamics can result in pathological states. As terminal site of nutrient oxidation for cell, powerhouses harness energy form ATP process driven electron transport chain. Contemporaneously, electrons translocated within chain undergo spontaneous side reactions oxygen, giving rise superoxide variety other downstream reactive oxygen species (ROS). Mitochondrially-derived ROS mediate redox signaling or, excess, cause cell injury even death. Recent evidence suggests that tightly coupled generation depending on physiological status cell. Yet, mechanism which changes shape modulate function homeostasis less clear. Aberrant morphology may lead enhanced formation, which, turn, deteriorate health further exacerbate oxidative stress self-perpetuating vicious cycle. Here, we review latest findings intricate relationship production, focusing mainly role malignant disease.
