The recent article published in Signal Transduction and Targeted Therapy sheds light on the significance of N6-methyladenosine(m6A)methyltransferase-like protein METTL14 in mitigating the progression of metabolic dysfunction-associated fatty liver disease(MAFLD).1 In this study,Wang et al.elucidated the downregulation of METTL14 in hepatocytes from both MAFLD patients and high-fat diet(HFD)-induced MAFLD mouse models,underscoring its pivotal role in maintaining hepatic lipid and redox homeostasis in normal livers.

Lysosomes are discrete organelles that act as recycling centers for extracellular and intracellular materials,playing a pivotal role in maintaining cellular homeostasis.Their acidic environment,maintained by numerous hydrolytic enzymes,facilitates substrate degradation.Dysfunction in lysosomal processes can lead to abnormal substrate degradation,significantly impacting cellular homeostasis.High energy-demanding cells,such as post-mitotic neurons,are especially vulnerable to these changes,often resulting in neurological diseases.Autophagy,a conserved catabolic process,requires extensive lysosomal utilization.It plays a key role in removing unnecessary intracellular components,ensuring cellular homeostasis,and promoting cell survival during stress conditions such as starvation,infection,or cellular damage.

Neurons are energy-demanding cells.Disruptions in energy metabolism can quickly interrupt neuronal function,leading to cell death and neurodegeneration.For instance,ischemia rapidly depletes adenosine triphosphate(ATP)thereby disrupting energy-dependent cellular processes crucial for homeostasis,and axon degeneration is preceded by a collapse of axonal ATP levels.

The critical role of calcium dyshomeostasis in the pathogenesis of Alzheimer’s disease(AD):AD is a progressive neurodegenerative disease characterized by cognitive decline,memory impairment,and behavioral changes.With an estimated 50 million people being affected worldwide,the incidence of AD is constantly increasing globally.The hallmark of AD is the accumulation of amyloid-beta protein(Aβ)in the form of amyloid plaques and hyperphosphorylated tau protein in the form of neurofibrillary tangles.However,increasing evidence suggests that calcium ion(Ca2+)dysregulation also plays a crucial role in the pathogenesis of AD(Calvo-Rodriguez and Bacskai,2021).As a key second messenger,Ca2+regulates a wide range of cellular processes,including the release of neurotransmitters,gene expression,and cell death.Ca^(2+)also regulates the activity of Calcium/calmodulin-dependent protein kinase II,which is critical for synaptic plasticity,learning,and memory(Kaushik et al.,2022).Alternation in the Ca^(2+)signal is an early event in the pathogenesis of AD,which can lead to synaptic dysfunction,neuronal loss,and cognitive impairment.

Neurodegenerative diseases,such as Alzheimer’s disease,Parkinson’s disease,and amyotrophic lateral sclerosis,despite the diversity in clinical symptoms,share a striking feature at the cellular level:the accumulation of insoluble aggregates of misfolded proteins that are sequestered in intraneuronal inclusion bodies.Besides mutations in disease-associated proteins that render them aggregation-prone,the decline of protein homeostasis(i.***.proteostasis)with aging is also believed to be a contributing factor to the accumulation of protein aggregates.

Macrophages and neutrophils are key components of myeloid cells and play critical roles in innate immune responses,organ formation,and tissue homeostasis.The integrity of their functions heavily relies on the generation of a proper number of mature macrophages and neutrophils through embryonic and adult myelopoiesis.In mammalian adult myelopoiesis,oligopotent common myeloid progenitors(CMPs)are known to be the earliest myeloid progenitors,which give rise to granulocyte-macrophage progenitors(GMPs),subsequently differentiate into unipotent neutrophil and macrophage precursors,and finally,mature macrophages and neutrophils(Orkin and Zon,2008).In contrast,the ontogeny of embryonic myelopoiesis and the mechanism underlying the formation of macrophages and neutrophils remainless understood.

Background:Development and homeostasis of the brain are enabled through the precise control of the cell microenvironment by the blood-brain barrier(BBB),which interfaces between the brain parenchyma and the lumen of blood microvessels,and by the blood-cerebrospinal fluid barrier,which separates the cerebrospinal fluid from the blood vessels of the choroid plexus(Villabona-Rueda et al.,2019).Here,the focus will be on the BBB,the impairment of which is considered the earliest common denominator in neurovascular diseases.

Phospholipids hold a multifaceted function in cellular biology.The primary function of phospholipids is to serve as essential building blocks of cell membranes,which gives cells crucial structural support and facilitates cellular organization.Beyond that,phospholipids also act as key signaling molecules that coordinate vital cellular processes such as organismal development,homeostasis,and adaptation to environmental changes.Despite being the smallest and simplest phospholipid,phosphatidic acid(PA)plays a crucial role as a metabolic intermediate and second messenger.

Fibroblast growth factor21(FGF21)is a hormone that can balance nutrient fluctuations,control metabolic processes,and maintain energy homeostasis.Endogenous FGF21 is produced by a variety of cell types,including hepatocytes,adipocytes,bone cells,myocardial cells,and pancreas cells,and act on various effector tissues such as brain,adipose tissue,liver,heart,and skeletal muscle.1 The target that FGF21 interacts with is the cell-surface receptor composed of FGF receptors in complex with the single-pass transmembrane proteinβ-Klotho.These receptors are abundantly expressed,both in peripheral tissues and some regions of the CNS,such as the hypothalamus and amygdala and the locus coeruleus(LC).2 Physiologically,FGF21 can be induced by various metabolic stresses,including hunger,protein deficiency,monosaccharides,and alcohol,by acting onβ-Klotho receptor in corresponding tissues,ultimately exerting regulatory effects(Fig.1)

For decades,the immune system has been associated with host protection against infectious pathogens or tumors,while also contributing to autoimmunity.Notwithstanding,this paradigm is now changing,with recent studies highlighting novel roles for immune mediators in the maintenance of steady-state tissue homeostasis.In this perspective,we review some of the latest findings featuring immune modulators of the nervous system pathophysiology,with a special focus on interleukin(IL)-17.
