Does astrocytic L-lactate enhance cognition through myelination?

Introduction:Astrocytes,the predominant glial cell in the brain,play a vital role in a plethora of central nervous system *** are the major storage site of glycogen in the central nervous *** produce L-lactate by glycogenolysis and glycolysis which is then transported to neurons(Magistretti and Allaman,2018).Multiple evidence using diverse behavioral paradigms,such as fear conditioning,conditioned place avoidance,rat gambling task(RGT),and flavor-place paired associate(PA)learning suggest that L-lactate has a beneficial effect on various aspects of cognition(Wang et al.,2017;Akter et al.,2023b).While the molecular mechanisms underlying the cognitive benefits of L-lactate are still emerging,it is well-established that astrocytic L-lactate can be used as an energy substrate by neurons and can induce N-methyl-D-aspartate receptor-dependent plasticity-driven gene expression during cognition(Magistretti and Allaman,2018).Additionally,recent evidence has revealed more roles of L-lactate which include myelination,neuronal mitochondrial biogenesis,and antioxidant defense(Sanchez-Abarca et al.,2001;Ichihara et al.,2017;Akter et al.,2023a,b).Myelin in the central nervous system is a specialized lipid-rich membrane formed by oligodendrocytes.

Under the pressure of carbon neutrality,many carbon capture,utilization and storage technologies have witnessed rapid development in the recent years,including oxy-fuel combustion(OFC)***,the conventional OFC technology usually depends on the flue gas recirculation system,which faces significant investment,high energy consumption,and potential low-temperature corrosion *** these deficiencies,the direct utilization of pure oxygen to achieve particle fluidization and fuel combustion may reduce the overall energy consumption and CO_(2)-capture *** this paper,the fundamental structure of a self-designed 130 t·h^(-1) pure-oxygen combustion circulating fluidized bed(CFB)boiler was provided,and the computational particle fluid dynamics method was used to analyze the gas-solid flow characteristics of this new-concept boiler under different working *** results indicate that through the careful selection of design or operational parameters,such as average bed-material size and fluidization velocity,the pure-oxygen combustion CFB system can maintain the ideal fluidization state,namely significant internal and external particle ***,the contraction section of the boiler leads to the particle backflow in the lower furnace,resulting in the particle suspension concentration near the wall region being higher than that in the center ***,the upper furnace still retains the classic core-annulus flow *** addition to increasing solid circulation rate by reducing the average bed-material size,altering primary gas ratio and bed inventory can also exert varying degrees of influence on the gas-solid flow characteristics of the pure-oxygen combustion CFB boiler.
