Accumulating evidence from animal and human studies supports the notion that physical exercise can enhance neuroplasticity thus reduce risk of several neurodegenerative diseases (e.g., dementia). However, underlying neurobiological mechanisms induced are still largely unknown. One potential mediator effects is neurotrophin BDNF, which enhances via different pathways synaptogenesis, neurogenesis, long-term potentiation). Current research has shown (i) increased peripheral lactate levels (following high intensity exercise) associated with BDNF levels, (ii) infusion at rest increase central (iii) plays a very complex role in brain's metabolism. In this review, we summarize relationship neuroplasticity.

Monocarboxylate transporters (MCTs) constitute a family of 14 members among which MCT1-4 facilitate the passive transport monocarboxylates such as lactate, pyruvate and ketone bodies together with protons across cell membranes. Their anchorage activity at plasma membrane requires interaction chaperon protein basigin/CD147 embigin/gp70. are expressed in different tissues where they play important roles physiological pathological processes. This review focuses on brain cancer. In brain, MCTs control delivery produced by astrocytes, to neurons, it is used an oxidative fuel.

Brain lactate concentration is higher during wakefulness than in sleep. However, it unknown why arousal linked to an increase brain and declines within minutes of Here, we show that the glymphatic system responsible for state-dependent changes concentration. Suppression function via acetazolamide treatment, cisterna magna puncture, aquaporin 4 deletion, or body position reduced decline normally observed when awake mice transition into sleep anesthesia. Concurrently, same manipulations diminished accumulation cervical, but not inguinal lymph nodes were anesthetized. Thus, our study suggests excellent biomarker sleep-wake cycle increases further deprivation, because inversely correlated with glymphatic-lymphatic clearance. This analysis provides fundamental new insight energy metabolism by demonstrating glucose fully oxidized can be exported as fluid transport.

For decades, lactic acid has been considered a dead-end product of glycolysis. Research in the last 20+ years shown otherwise. Through its transporters (MCTs) and receptor (GPR81), plays key role multiple cellular processes, including energy regulation, immune tolerance, memory formation, wound healing, ischemic tissue injury, cancer growth metastasis. We summarize findings signaling, functions, many remaining questions.

More than two hundred years after its discovery, lactate still remains an intriguing molecule. Considered for a long time as waste product of metabolism and the culprit behind muscular fatigue, it was then recognized important fuel many cells. In particular, in nervous system, has been proposed that lactate, released by astrocytes response to neuronal activation, is taken up neurons, oxidized pyruvate used synthesizing acetyl-CoA be tricarboxylic acid cycle. recently, addition this metabolic role, discovery specific receptor prompted reconsideration now seen sort hormone, even involved processes complex memory formation neuroprotection. As matter fact, exercise offers benefits our organisms, seems delay brain aging neurodegeneration. Now, induces production release into blood which can reach liver, heart, also brain. Can beneficial molecule produced during exercise, offer neuroprotection? review, we summarize what have known on discussing roles attributed over time.

Memory, the ability to retain learned information, is necessary for survival. Thus far, molecular and cellular investigations of memory formation storage have mainly focused on neuronal mechanisms. In addition neurons, however, brain comprises other types cells systems, including glia vasculature. Accordingly, recent experimental work has begun ask questions about roles non-neuronal in formation. These studies provide evidence that all glial (astrocytes, oligodendrocytes, microglia) make important contributions processing encoded information storing memories. this review, we summarize discuss findings critical role astrocytes as providers energy long-lasting changes are long-term We focus three main findings: first, glucose metabolism learning- activity-dependent metabolic coupling between neurons service formation; second, astrocytic arousal, a state contributes very detailed memories; finally, light high demands during early development, will possible metabolisms early-life conclude by proposing future directions discussing implications these health disease.
