Psicobiologia dello stress

Psicobiologia dello stress

Nel nostro laboratorio siamo interessanti a comprendere come i microRNA regolano la neurotrasmissione in specifici circuiti cerebrali nella regolazione di comportamenti difensivi innati. Per i nostri studi utilizziamo approcci in-vivo (fiber photometry, in-vivo microdialysis, optogenetics) e ex-vivo su modelli murini geneticamente modificati.

MicroRNA-34a regulates the depression-like behavior in mice by modulating the expression of target genes in the Dorsal Raphè

Chronic or cumulative stress sustained over a long period of time increases the risk of affective illness. Mounting clinical and preclinical evidences support the involvement of the miR-34 family of microRNAs in stress-related psychiatric conditions and in the neurobiological mechanisms that underlie the regulation of stress response.

Early-onset behavioral and neurochemical deficits in the genetic mouse model of phenylketonuria

Phenylketonuria (PKU) is one of the most common human inborn errors of metabolism, caused by phenylalanine hydroxylase deficiency, leading to high phenylalanine and low tyrosine levels in blood and brain causing profound cognitive disability, if untreated. Since 1960, population is screened for hyperphenylalaninemia shortly after birth and submitted to early treatment in order to prevent the major manifestations of the disease.

Pharmacological treatment of depression in Alzheimer's disease: a challenging task

Besides the memory impairment, Alzheimer's disease (AD) is often complicated by neuropsychiatric symptoms also known as behavioral and psychological symptoms of dementia, which occur in one-third of patients at an early stage of the disease. Although the relationship between depressive disorders and AD is debated, the question if depression is a prodromal symptom preceding cognitive deficits or an independent risk factor for AD is still unclear.

Old neurochemical markers, new functional directions?: an editorial for ‘Distinct gradients of various neurotransmitter markers in caudate nucleus and putamen of the human brain’ on page 650

The dorsal striatum coordinates input-output processing of numerous functions including those related to motor activity, motivation, and learning. Considerable anatomical and biochemical heterogeneity across striatal subregions has long been known to result in distinct functional outcomes, and for imbalances in these pathways to contribute to many complex disorders.

Water extract from inflorescences of industrial hemp futura 75 variety as a source of anti-inflammatory, anti-proliferative and antimycotic agents: results from in silico, in vitro and ex vivo studies

Industrial hemp (Cannabis sativa) is traditionally cultivated as a valuable source of fibers and nutrients. Multiple studies also demonstrated antimicrobial, anti-proliferative, phytotoxic and insecticide effects of the essential oil from hemp female inflorescences. On the other side, only a few studies explored the potential pharmacological application of polar extracts from inflorescences. In the present study, we investigated the water extract from inflorescences of industrial hemp Futura 75 variety, from phytochemical and pharmacological point of view.
