Dr Castorina began his academic journey at the Department of Anatomy "G.F. Ingrassia" in Catania (Italy) in 2004, where he worked on his Master Degree thesis entitled "Biomechanics of the coxo-femural joint - the positive effects of physical activity". In 2005 he started an internship at the same Department, and had the unique possibilty to receive research training on several molecular and cell biology techniques. Soon after he undertook PhD studies and early in 2009 he received his PhD in Neuropharmacology. For the subsequent 2 years he continued to pursue his molecular studies as a post-doctoral fellow, an appointment that was extended for a 3rd year thanks to his successful scientific achievements. In 2011 he was appointed as Lecturer in Human Anatomy and Neuroanatomy at the University of Catania, and his role was confirmed as Senior four years later.
In 2014 he was awarded an International Research Collaborative Award from the University of Sydney to work in collaboration with the School of Molecular Bioscience. This award gave Dr Castorina the opportunity to also visit Sydney and appreciate this wonderful Country. As a consequence, in September 2015 he took a 1 year sabbatical to join the Discipline of Anatomy & Histology (University of Sydney) as a Research Fellow.
In 2016 Dr Castorina took on a new challenge by deciding to move permanently to Australia and pursue his future academic career here in Sydney. In September 2016 he was appointed as Senior Lecturer in Human Anatomy by the University of Technology Sydney (UTS).
Dr Castorina is now Deputy Discipline Leader for the discipline of Medical Science at UTS. He is also the Head of the Laboratory of Cellular and Molecular Neuroscience (LCMN). In 2019, Dr Castorina also joined the Australial Society for Medical Research NSW State committee, where he is the current Deputy Convenor for the ASM 2019.
Dr Castorina has more than 40 publications in international journals and has authored a book chapter. His current H-Index is 16 (according to Scopus), with more than 500 citations.

His research interests in the last ten years have been focused on investigating the broad function of two neuroprotective/immunomodulatory neuropeptides known as PACAP and VIP in cellular systems (in vitro) and experimental animals (in vivo), with the aim to get a better understanding of the potential therapeutical implications of these endogenously produced protective molecules in the treatment of neurodegenerative / neuroinflammatory / neurological / neurotraumatic conditions.
A parallel line of research, carried out in collaboration with the Section of Pharmacology at the University of Catania (Italy), has been to comprehend the involvement of dopamine D3 receptors in the development or resilience to addictive behaviors and in mediating dopamine-driven acquisition of fear-related memories.
Having identified many of the potential therapeutical benefits (but also drawbacks) arising from the use of PACAP and VIP in his past research activities, Dr Castorina is now planning to start a new series of investigations with the aim to identify novel upstream post-transcriptional mechanisms governing endogenous PACAP/VIP gene expression in neuronal cells and in rodent models of disease.
Dr Castorina international teaching experience encompasses Human Anatomy in all its aspects, including Musculoskeletal, Visceral, Neuroanatomy and Functional Neuroscience.
He had taught Human Anatomy to both Medical and Science students both in Italy and in Australia. He also taught Visceral and Neuroanatomy in several Allied Health courses, including Neurorehabilation Technicians, Speech Therapy and Orthoptics.
His teaching interests are mainly concentrated in understanding the physical connections between different cortical and subcortical brain structures and their function, but he is also devoted to get deliver to student the knowledge necessary to understand the relationship between the morphology of organ systems and their physiological function.
He lectures and tutors in the subjects Neuroscience (91706) at UTS and for the Notre Dame Medical School (MED1000 and MED2000) and he is the Subject Coordinator for Human Anatomy 2 (91812) and Human Anatomy 3 (91813), two core subjects of the Bachelor of Advanced Sciences.

© 2019 Osteoarthritis (OA) is a degenerative disease of the articular cartilage, resulting in pain and total joint disability. Recent studies focused on the role of the metabolic syndrome in inducing or worsening joint damage suggest that chronic low-grade systemic inflammation may represent a possible linking factor. This finding supports the concept of a new phenotype of OA, a metabolic OA. The gut microbiome is fundamental for human physiology and immune system development, among the other important functions. Manipulation of the gut microbiome is considered an important topic for the individual health in different medical fields such as medical biology, nutrition, sports, preventive and rehabilitative medicine. Since intestinal microbiota dysbiosis is strongly associated with the pathogenesis of several metabolic and inflammatory diseases, it is conceivable that also the pathogenesis of OA might be related to it. However, the mechanisms and the contribution of intestinal microbiota metabolites in OA pathogenesis are still not clear. The aim of this narrative review is to review recent literature concerning the possible contribution of dysbiosis to OA onset and to discuss the importance of gut microbiome homeostasis maintenance for optimal general health preservation.

Multiple sclerosis (MS) is a devastating disease, and with the increasing number of cases each year, it is becoming a significant socioeconomic burden for the affected people and the entire community. The aetiology of MS is largely unknown, but genetic susceptibility, exposure to infections and/or environmental toxicants are recognised as risk factors. MS is characterised by the appearance of lesions/plaques in the central nervous system, caused by destruction of the myelin sheet by auto-reactive T cells. Symptoms range from mild impairment of daily motor functions to severe sensory and cognitive disabilities necessitating mobility assistance, medical and support from caregivers. Due to the progressive nature of the disease, MS is gaining more attention and research to better understand its multifaceted pathogenesis. In the present review, we focus on some of the latest research related to the neuroinflammatory component of the disease, since it appears to play a critical role in MS pathogenesis. The goal is to shed more light on this specific domain of MS, in an attempt to assist in the identification of novel treatment trajectories and management plans.
Dipeptidyl peptidase IV (DPP-IV) is a serine protease best known for its role in inactivating glucagon-like peptide-1 (GLP-1), pituitary adenylate cyclase-activating polypeptide (PACAP) and glucose-dependent insulinotropic peptide (GIP), three stimulators of pancreatic insulin secretion with beneficial effects on glucose disposal. Owing to the relationship between DPP-IV and these peptides, inhibition of DPP-IV enzyme activity is considered as an attractive treatment option for diabetic patients. Nonetheless, increasing studies support the idea that DPP-IV might also be involved in the development of neurological disorders with a neuroinflammatory component, potentially through its non-incretin activities on immune cells. In this review article, we aim at highlighting recent literature describing the therapeutic value of DPP-IV inhibitors for the treatment of such neurological conditions. Finally, we will illustrate some of the promising results obtained using berberine, a plant extract with potent inhibitory activity on DPP-IV.

Following peripheral nerve injury, dysregulations of certain non-coding microRNAs (miRNAs) occur in Schwann cells. Whether these alterations are the result of local inflammation and/or correlate with perturbations in the expression profile of the protective vasoactive intestinal peptide (VIP)/pituitary adenylate cyclase-activating polypeptide (PACAP) system is currently unknown. To address these issues, we aimed at profiling the expression of selected miRNAs in the rat RT4 Schwann cell line. Cells exposed to lipopolysaccharide (LPS), to mimic the local inflammatory milieu, were appraised by real-time qPCR, Western blot and ELISAs. We found that upon LPS treatment, levels of pro-inflammatory cytokines (IL-1β, -6, -18, -17A, MCP-1 and TNFα) increased in a time-dependent manner. Unexpectedly, the expression levels of VIP and PACAP were also increased. Conversely, levels of VPAC1 and VPAC2 receptors were reduced. Downregulated miRNAs included miR-181b, -145, -27a, -340 and -132 whereas upregulated ones were miR-21, -206, -146a, -34a, -155, -204 and -29a, respectively. Regression analyses revealed that a subset of the identified miRNAs inversely correlated with the expression of VPAC1 and VPAC2 receptors. In conclusion, these findings identified a novel subset of miRNAs that are dysregulated by immune challenge whose activities might elicit a regulatory function on the VIP/PACAP system.

© 2016 Elsevier Inc.Angiogenesis plays a crucial role in progression of pleural malignant mesothelioma. A significantly increased incidence of pleural mesothelioma has been attributed to exposure to fluoro-edenite, a fibrous amphibole extracted from a local stone quarry. In this study, we have investigated the expression of CD68-positive macrophages, tryptase-positive mast cells and CD31 positive areas, as expression of microvascular density, in lung tissue of sheeps exposed to fluoro-edenite fibers vs controls, by immunohistochemical, morphometric and Western blot analysis. The result have evidenced a significant increase in the expression of CD68-positive macrophages, tryptase-positive mast cells as well as a significant increase in microvascular density evaluated as CD31 positive areas in lung tissue of of sheeps exposed to fluoro-edenite fibers vs controls. These data confirmed the important role played by tumor microenvironment components, including macrophages and mast cells, in favour of angiogenesis in pleural mesothelioma induced by fluoro-edenite exposure.

Emerging evidence indicates that the dopamine D3 receptor (D3R) mediates protective roles both in neuronal and non-neuronal cell lines. In a previous study we proposed that neurofibromin, a large tumor suppressor protein encoded by the neurofibromatosis type 1 gene (NF1), may increase susceptibility to apoptosis after serum deprivation in malignant peripheral nerve sheath tumor (MPNST) cells, thus acting as a proapoptotic gene. In addition, it has been observed that D3Rs are functionally correlated to neurofibromin. In this study, we examined whether 7-OH-PIPAT, a potent dopamine D3R agonist, exerts an antiapoptotic role under the same culture conditions and then correlated this effect to changes in NF1 expression. Results showed that serum deprivation caused a significant reduction of cell viability (MTT assay) both after 24 and 48 h (p<0.001). Treatment with increasing concentrations of 7-OH-PIPAT (10-9-10-5 M) induced a progressive increase in cell viability both after 24 and 48 h as compared to vehicle-treated cells, with significant changes at the highest concentrations tested (10-6 and 10-5 M). Consistently, at the latter two concentrations, a significant reduction in oligonucleosomes formation was observed, thus suggesting an antiapoptotic role of 7-OH-PIPAT. These results were confirmed by Hoechst 33254 nuclear staining. To investigate whether these effects were correlated to changes in NF1 transcript and protein expression, quantitative real-time PCR, Western blot and immunofluorescence analyses were performed. Results demonstrated that the upregulation of NF1 transcripts and protein levels induced by serum withdrawal were remarkably attenuated by 10-6 and 10-5 M agonist treatment within 24 h (p<0.01 and p<0.001, respectively), whereas similar effects were observed already at a lower concentration (10-7 M) after 48 h treatment (p<0.001). In conclusion, these results suggest that D3R might mediate the protective response to serum deprivation in MPNST cell...
