The epileptogenesis process is associated with large-scale changes in gene expression, which contribute to the remodelling of brain networks permanently altering excitability. About 80% of the protein coding genes are under the influence of the circadian rhythms. These are 24-hour endogenous rhythms that determine a large number of daily changes in physiology and behavior in our bodies. In the brain, the master clock regulates a large number of pathways that are important during epileptogenesis and established-epilepsy, such as neurotransmission, synaptic homeostasis, inflammation, blood-brain

Epileptogenesis is a gradual and dynamic process leading to difficult-to-treat seizures. Several cellular, molecular, and pathophysiologic mechanisms, including the activation of inflammatory processes. The use of human brain tissue represents a crucial strategy to advance our understanding of the underlying neuropathology and the molecular and cellular basis of epilepsy and related cognitive and behavioral comorbidities, The mounting evidence obtained during the past decade has emphasized the critical role of inflammation in the pathophysiological processes implicated in a large spectrum o

Cancer-related fatigue is a prominent and debilitating side effect of cancer and its treatment. It can develop prior to diagnosis, generally peaks during cancer treatment, and can persist long after treatment completion. Its mechanisms are multifactorial, and its expression is highly variable. Unfortunately, treatment options are limited. Our research uses syngeneic murine models of cancer and cisplatin-based chemotherapy to better understand these mechanisms. Our data indicate that both peripherally and centrally processes may contribute to the developmental of fatigue. These processes includ

My research focuses broadly on the lifelong health disparities associated with experiences of adversity early in life. In this talk I will present the results of our recently completed Teen Resilience Project, a prospective and longitudinal study of first onset depression during adolescence. First, I will present the results on whether and how inflammatory processes may be shaped by early life adversity. Second, I will present data on the role of stress-induced inflammation in reward-related psychological processes. Finally, I will discuss the biobehavioral predictors of first-onset depression

Our goal is to understand why myelin repair fails in multiple sclerosis and to develop regenerative medicines for the nervous system. A central obstacle for progress in this area has been the complex biology underlying the response to CNS injury. Acute CNS damage is followed by a multicellular response that encompasses different cell types and spans different scales. Currently, we do not understand which factors determines lesion recovery. Failure of inflammation to resolve is a key underlying reason of poor regeneration, and one focus is therefore on the biology of microglia during de- and re

Every year around 100,000 people in the UK will have a stroke. Stroke is a leading cause of adult disability, and cerebrovascular disease more broadly is a major cause of dementia. Understanding these diseases – both acute and chronic manifestations of cerebrovascular disease – requires consideration not only of the brain itself, but also the blood vessels supplying it. Atherosclerosis – the hardening of arteries as we age – may predispose to stroke by triggering the formation of blood clots that block the blood supply to the brain, but also involves inflammation that may cause chronic damage

There are currently no approved therapies to slow down the accumulation of neurological disability that occurs independently of relapses in multiple sclerosis (MS). International agencies are engaging to expedite the development of novel strategies capable of modifying disease progression, abrogating persistent CNS inflammation, and support degenerating axons in people with progressive MS. Understanding why regeneration fails in the progressive MS brain and developing new regenerative approaches is a key priority for the Pluchino Lab. In particular, we aim to elucidate how the immune system, i

Inflammation is a key component of the innate immune response. Primarily designed to remove noxious agents and limit their detrimental effects, the prolonged and/or inappropriately scaled innate immune response may be detrimental to the host and lead to a chronic disease. Indeed, there is increasing evidence suggesting that a chronic deregulation of immunity may represent one of the key elements in the pathobiology of many brain disorders. Microglia are the principal immune cells of the brain. The consensus today is that once activated microglia/macrophages can acquire a wide repertoire of pro

ONS figures suggest that at least 10% of individuals suffering COVID -19 Infection continue to experience several weeks after testing positive, and other studies report the proportions as even higher (e.g. Logue et al., 2021). One of the most prevalent reported symptoms among these “Long Covid” sufferers is cognitive dysfunction (Davis et al., 2020). However, to date the cognitive sequelae of COVID -19 are little understood. There are a number of reasons why COVID -19 infection might be associated with cognitive impairment and mental illness (e.g. Bougakov et al., 2020). In particular, increas

An imbalance in lipid metabolism in neurodegeneration is still poorly understood. Phospholipids (PLs) have multifactorial participation in vascular dementia as Alzheimer, post-stroke dementia, CADASIL between others. Which include the hyperactivation of phospholipases, mitochondrial stress, peroxisomal dysfunction and irregular fatty acid composition triggering proinflammation in a very early stage of cognitive impairment. The reestablishment of physiological conditions of cholesterol, sphingolipids, phospholipids and others are an interesting therapeutic target to reduce the progression of AD

Recent research highlights inflammation's pivotal role in the etiology of psychotic disorders, emphasizing the potential of inflammatory markers as diagnostic and prognostic tools. This study aimed to elucidate the differential profiles of neutrophil-to-lymphocyte ratio(NLR), monocyte-to-lymphocyte ratio(MLR), platelet-to-lymphocyte ratio(PLR), and systemic immune-inflammatory index(SII) in schizophrenia versus acute psychosis. Conducting a retrospective analysis, we included 126 patients from Prof. Dr. Alexandru Obregia Hospital in Bucharest, divided into two cohorts: 67 patients diagnosed wi
