Dissertation: Elucidating the role of the hypoxia associated factor (HAF) in NASH-driven hepatocellular carcinoma
Hepatocellular carcinoma is raising in the US due to an increase in the prevalence of obesity. Mouse models of HAF developed NASH-related HCC tumors suggesting HAF has a tumor suppressor role in HCC initiation. So far, I have found that HAF promotes the activation of the NF-kB pathway, potentially, through transcriptional regulation of TRADD and RIP1.

Dissertation: Determining the role of E3 ligase-substrate interation networks during early development
We have developed a microfluidics-based, high-throughput in vivo CRISPR/Cas9 genetic screening platform (MIC-Drop) that can be coupled to multiple downstream phenotypic readouts to examine gene function at a large scale in a vertebrate system. There are 634 human E3s, many of which have not been thoroughly characterized because of the complexity of the ubiquitin system and a lack of high-throughput technologies to study it have hindered the elucidation of the functions of the majority of E3s in early development. We propose to advance the understanding of the functional roles of E3s during early development by using MIC-Drop to mutagenize all E3 ligase orthologs in the zebrafish, perform morphometric evaluations of the mutagenized larvae to pinpoint E3-induced developmental changes and investigate the mechanisms of E3/E3-substrate pair function in development using both proteomics and classical biochemical approaches.

Dissertation: Development of focused ultrasound (FUS) approaches to modify neural circuits underlying seizures in temporal lobe epilepsy (TLE).
Carena's research focuses on FUS, which is a promising noninvasive technology that can be used for therapeutic purposes by ablating tissue or modulating neural circuit function. FUS could be used to reduce seizure frequency for the one-third of people with drug-resistant epilepsy that may not opt for surgery or may not be a good candidate for surgery.

Dissertation: Changes in structure and function of NG2-Glia during viral encephalitis
Theiler’s Murine Encephalomyelitis Virus (TMEV) is used to model virally induced seizures and epilepsy in mice. NG2-glia, also known as oligodendrocyte precursor cells, may contribute to the clearance of virus from the brain and may also contribute to seizure burden during acute infection. I am studying the synapses formed between NG2-glia and neurons, as well as the phagocytic activity of NG2-glia, in response to TMEV infection.

Dissertation: A pharmacokinetic and efficacy study of a relevant combination therapy in a mouse model of Dravet Syndrome
Dravet Syndrome (DS) is a rare but catastrophic infantile-onset genetic epilepsy characterized by febrile and spontaneous seizures with significant comorbidities. The use of monotherapies do fail to provide adequate seizure control in patients; thus, combination therapies have become important. However, there is a limited understanding of drug-drug interactions of antiseizure polytherapy, impeding therapy decision-making. This study utilizes a DS mouse model and a standard-of-care therapeutic approach as a proof-of-principle study to provide an essential drug discovery platform to inform future preclinical studies for new investigational compounds.

Dissertation: Mechanisms Underlying the Histone Modifier kdm6b’s Contribution to Development of Autism
The etiology of autism spectrum disorder (ASD) is partly explained by deficits in GABAergic neuron development in cortical regions and altered dynamics of histone lysine methyl modifications. I study the role of histone methyl modifiers in the development of autism with focus on GABAergic neuron development. The results of this study will further uncover potential selective drug targets for the treatment of autism.

Dissertation: Regulation of mitochondrial quality control by t-tubule microdomains in healthy and failing cardiomyocytes
Heart failure with preserved ejection fraction (HFpEF) is marked by mitochondrial dysfunction and increased oxidative stress. To better understand the molecular basis for this dysfunction, I study the regulation of mitochondrial quality control by cardiomyocyte transverse-tubule microdomains. Restoration of t-tubule microdomains offers a potential therapeutic approach to restoring mitochondrial function.

Dissertation: Discovering Novel Antibiotic RiPP (Ribosomally Synthesized and Post-Translationally Modified Peptide) Natural Products and Elucidating Their Biosynthesis by Great Salt Lake Actinomycetota
From a combination of genomic, metabolomic, and activity-guided screening techniques, our preliminary data show that actinomycetota isolated from Great Salt Lake sediment represent unique evolutionary lineages with a wealth of undescribed biosynthetic potential and many have demonstrated activity against multidrug resistant ESKAPE pathogens. Their genomes contain several novel RiPP biosynthetic gene clusters (BGCs), including many lasso peptide and linaridin BGCs with previously unreported post-translational modification enzymes (PTMEs). My goals are to isolate these RiPPs in order characterize their structures and activities to describe their biosynthesis and characterize these potentially novel PTMEs.

Dissertation: Coordinated Regulation of TRPA1, TRPV3, and Kinase Signalling Pathways in Lung Epithelial Cell Damage and Repair Following Environmental Pollutant Exposure
TRPA1 and TRPV3 have been found to be differentially expressed following various forms of lung epithelial cell injury. Kinase signaling pathways linked to growth factor signaling, and potentially TRP channels, may provide protection against environmental air pollutant injury in lung epithelial cells. Through inhibition or activation of various kinases followed by activation of TRPA1 and/or TRPV3, this may offer protection against damage and aid in lung epithelial cell recovery.

Dissertation: Cell-type-specific adaptations in the dorsal striatum of habitual cocaine-seeking behavior
My research involves the study of cell-type-specific adaptations in the dorsal striatum of habitual cocaine-seeking behavior. Excitatory synaptic function and plasticity following prolonged cocaine administration is likely contributing to the induction of behavioral states underlying habitual control of behavior. It is hypothesized that better understanding of excitatory synaptic transmission in the context of addiction will pave the way for therapeutic targets for novel treatments.

I have obtained my Ph.D. in Neuroscience from the University of Brescia – School of Medicine, Italy. During my academic experience, I have mainly worked on dissecting the molecular mechanisms of neurodegenerative diseases, such as Alzheimer´s disease, by using animal models and biochemical and molecular analyses. I have mainly been involved in project analyzing the pathways of programmed cell death, which lead to neuronal loss in several neurodegenerative conditions. Thanks to this experience, I was able to implement new and original approaches to neuroscience research. I am currently a Post Doc in the Bortolato’s lab, where I principally work on neurodevelopmental disorders, such as Tourette syndrome, to understand the underpinning mechanisms in order to be able to develop new therapeutical strategies.

I joined the Peterson lab in late 2020, after earning my PhD in Cell and Developmental Biology working in the lab of Dr. Brian Link at the Medical College of Wisconsin. As a postdoc in the Peterson lab I'm studying how skin functions as a sensory organ contributing to touch, itch, and pain sensation. To that end, I'm performing high-throughput genetic screens in zebrafish, and examining how the genes identified in these screens regulate the join development of the skin and it's innervating sensory neurons. I'm also using zebrafish to model rare and/or undiagnosed diseases, with a goal of developing screening platforms capable of identifying potential therapeutics for patients with these conditions.

I’m a behavioral pharmacologist and I have obtained my Ph.D. in Pharmacology in 2007 from the University of Cagliari, Italy.
During my over 10 years of scientific experience in the US, I focused my research on the characterization of the biological bases of neurodevelopmental disorders through the employment of behavioral tests in animal models, and on the characterization of biochemical and molecular mechanisms of psychoactive drugs acting at the level of the basal ganglia. I did my first postdoctoral at the National Institute on Drug Abuse (NIDA/IRP) working on the mechanisms of action of addictive drugs acting at the level of the basal ganglia. I have been mainly involved in projects examining functional and pharmacological significance of receptor heteromers, particularly the adenosine A2A receptor forming heteromers with the adenosine A1 receptor and D2 receptor, in animal models of drug abuse with different in vivo approaches.
My first experience at the Bortolato lab was in 2016 when I worked on a project for the identification of biomarkers and therapeutical targets for the prevention and treatment of pramipexole-increased risk-taking behaviors in a rodent animal model of gambling. From years 2020 to 2022 I combined research and teaching activities at PNU (Precarpathian National University) in Ukraine where I focused my research on the characterization of biochemical and molecular mechanisms of phytobiotic compounds on neurodevelopmental disorders in animal models of aging.
My current projects at the Bortolato’s lab are to examine the functional and pharmacological significance of neurosteroids using a 6-Hydroxy Dopamine (6-OHDA) animal model of neurotoxicity in animal models of Parkinson’s disease and to study the effects produced by brain-selective knock-down molecular constructs (KD) using viral approaches. The goal of this research is to clarify the role played by neurosteroids in the modulation of behavioral responses in animal models of PD.

I've always been fascinated about understanding underlying pathogenic mechanisms that contribute to disease phenotypes in order to identify novel drug targets. Epilepsy is a neurological disorder that affects more than 65 million people globally and has a complex pathophysiology. Pediatric epilepsies, in particular, are devastating and negatively impact the quality of life of patients and their caregivers. My research interests are multifaceted and include the following: (i) investigating how environmental pollutants might affect seizure outcomes in the Dravet Syndrome, a rare but catastrophic pediatric epilepsy (ii) understanding the role of metabolic alterations in causing sudden unexpected death in epilepsy (SUDEP) in Dravet Syndrome, and (iii) screening of drug compounds in the Dravet Syndrome mouse model which would aid in the identification of the next novel compound that could potentially treat certain genetic pharmacoresistant epilepsies. I work with mouse models of epilepsy, in particular the Dravet Syndrome mouse model. I have also worked with in-vitro and zebrafish models of hyperexcitability/seizures.
