Mitochondria are central to neuronal health, serving as the primary energy producers within cells. This vital role makes them a focal point in understanding various neurological disorders. Across conditions such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis (ALS), multiple sclerosis, neuroinflammatory disorders, neurodevelopmental disorders, stroke, and traumatic brain injury (TBI), mitochondrial dysfunction emerges as a common thread. In Alzheimer's disease, for instance, dysfunctional mitochondria contribute to the accumulation of amyloid-beta plaques and tau protein tangles, accelerating neurodegeneration. Similarly, in Parkinson's disease, mitochondrial impairment disrupts cellular energy production, exacerbating the loss of dopaminergic neurons and leading to motor dysfunction. ALS, characterized by the progressive degeneration of motor neurons, also exhibits mitochondrial dysfunction, further contributing to the disease pathology. Additionally, in conditions like multiple sclerosis and neuroinflammatory disorders, dysfunctional mitochondria exacerbate inflammation and neuronal damage. The role of mitochondria extends beyond neurodegenerative diseases; in neurodevelopmental disorders such as autism and intellectual disabilities, disturbances in mitochondrial dynamics impact neuronal connectivity and synaptic function. Furthermore, mitochondrial impairment plays a significant role in acute neurological insults like stroke and TBI, exacerbating neuronal injury and complicating recovery processes. Despite the challenges posed by mitochondrial dysfunction in neurological disorders, there is growing interest in mitochondrial therapeutics as a promising avenue for neuroprotection and disease modification. Investigating the neuroprotective potential of mitochondrial-targeted interventions opens new avenues for therapeutic development and offers hope for mitigating the impact of mitochondrial dysfunction across a spectrum of neurological conditions.

Mitochondrion, a sub-cellular organelle originated from primary endosymbiosis, plays a vital role in energy metabolism of eukaryotic cells. The transfer of electrons through the electron transport chain (ETC) to molecular oxygen accompanied by the extrusion of protons from the matrix generate an electrochemical gradient across the inner mitochondrial membrane (IMM) that is used for ATP synthesis by oxidative phosphorylation. Despite many aspects of ATP synthesis have been delineated, regulatory mechanisms responsible for energy synthesis and transfer still remain to be uncovered. In addition to energy function, mitochondria play a crucial role in cell metabolism under both physiological and pathological conditions through their participation in many intracellular signaling pathways. Studies over the last 30 years provide strong evidence that mitochondria are the nexus of various stresses which initiate cell death through apoptosis, oncosis, necrosis and autophagy depending on the severity of the stress and cellular energy status. The release of several pro-apoptotic proteins such as cytochrome c, Smac/DIABLO, AIF, endonuclease G from intermembrane space initiates both caspase-dependent and caspase-independent apoptosis. The formation of the mitochondrial permeability transition pore in the IMM promotes cell death mostly through necrosis whereas a mild stress activates autophagy. Due to their critical roles in both cell death and survival mitochondria have been widely considered as an important target for various pharmacological and conditional therapeutic approaches. Currently, a large number of mitochondria-targeted agents are suggested to prevent (in ischemia reperfusion injury, cardiovascular, neurodegenerative and other diseases) or stimulate (in various cancers) cell death. This Research Topic focuses on the role of mitochondria in the regulation of cell metabolism and signaling under physiological and pathological conditions. Studies performed on cultured cells and isolated organs/tissues using different animal and cellular models of various diseases are also included and discussed.

From the preface: “Neural Metabolism In Vivo aims to provide a comprehensive overview of neurobiology by presenting the basic principles of up-to-date and cutting-edge technology, as well as their application in assessing the functional, morphological and metabolic aspects of the brain. Investigation of neural activity of the living brain via neurovascular coupling using multimodal imaging techniques extended our understanding of fundamental neurophysiological mechanisms, regulation of cerebral blood flow in connection to neural activity and the interplay between neurons, astrocytes and blood vessels. Constant delivery of glucose and oxygen for energy metabolism is vital for brain function, and the physiological basis of neural activity can be assessed through measurements of cerebral blood flow and consumption of glucose and oxygen.... This book presents the complex physiological and neurochemical processes of neural metabolism and function in response to various physiological conditions and pharmacological stimulations. Neurochemical detection technologies and quantitative aspects of monitoring cerebral energy substrates and other metabolites in the living brain are described under the “Cerebral metabolism of antioxidants, osmolytes and others in vivo” section. Altogether, the advent of new in vivo tools has transformed neuroscience and neurobiology research, and demands interdisciplinary approaches as each technology could only approximate a very small fraction of the true complexity of the underlying biological processes. However, translational values of the emerging in vivo methods to the application of preclinical to clinical studies cannot be emphasized enough. Thus, it is our hope that advances in our understanding of biochemical, molecular, functional and physiological processes of the brain could eventually help people with neurological problems, which are still dominated by the unknowns.” -- In-Young Choi and Rolf Gruetter

Part of the in-depth and practical Pattern Recognition series, Practical Surgical Neuropathology, 2nd Edition, by Drs. Arie Perry and Daniel J. Brat, helps you arrive at an accurate CNS diagnosis by using a pattern-based approach. Leading diagnosticians in neuropathology guide you from a histological (and/or clinical, radiologic, and molecular) pattern, through the appropriate work-up, around the pitfalls, and to the best diagnosis. Almost 2,000 high-quality illustrations capture key neuropathological patterns for a full range of common and rare conditions, and a "visual index" at the beginning of the book directs you to the exact location of in-depth diagnostic guidance. Instructive algorithms provide detailed guidance based on 8 major (scanning magnification) patterns and 20 minor (high magnification) patterns – helping you narrow the range of diagnostic possibilities. A user-friendly design color-codes patterns to specific entities, and key points are summarized in tables, charts, and graphs so you can quickly and easily find what you are looking for. Sweeping content updates keep you at the forefront of recent findings regarding gliomas, embryonal neoplasms, meningiomas, pituitary region and pineal tumors, epilepsy pathology, peripheral nerve sheath tumors, neurodegenerative disorders, tumor predisposition syndromes, and much more. Improved pattern call-outs are now linked directly within the chapter, reinforcing the patterns for more efficient and complete understanding.

Mitochondria are far more than the “powerhouse” of the cell as they have classically been described. In fact, mitochondria biological activities have progressively expanded to include not only various bioenergetic processes but also important biosynthetic pathways, calcium homeostasis and thermogenesis, cell death by apoptosis, several different signal transduction pathways mainly related to redox control of gene expression and so on. This functional and structural complexity may undergo important derangements so to justify the definition of ‘mitochondrial medicine’, which should include all the clinical consequences of congenital or acquired mitochondrial dysfunctions. There are actually a growing number of studies which assign a significant pathogenic role to damaged mitochondria in different diseases: ischemia/reperfusion injury, neurodegenerative diseases, cancer with its dramatic sequelae (i.e, metastasis), metabolic syndrome, hyperlipidemias, just to mention a few of the most important pathologies. In this context, a further aspect that should not be disregarded is the interaction of pharmacological agents with mitochondria, not only in regard of the toxicological aspects but, above all, of the potential therapeutic applications. In fact, it is interesting to note that, while the properties of different so-called “mitoxicants” are well-known, the subtle linkages between drugs and mitochondria is still in need of a real pharmacological and therapeutic control at the clinical level. This lack of consideration can often lead to an underestimation of unwanted toxic effects but also of desirable therapeutic activities. A reevaluation of the potential clinical role of mitochondria could give a new light on some yet obscure aspects of human pathophysiology.
