GENERAL DESCRIPTION

The team has two main research fields focused on one hand on the characterization of the molecular target of lipid mediators, such as leukotriene and thromboxane receptors and their physiological role, and on the other hand the study of neurophysiology with particular focus on the effects of a prolonged muscular inactivity on neurogenesis, neuro-muscular interaction and on the role of gene-environment interaction on the physiopathology of neuropsychiatric and neurodegenerative diseases.

RESEARCH TOPICS

  1. Characterization and classification of leukotriene receptors and their physio-pathological role
  2. Development and characterization of a new class of dualistic anti-inflammatory drugs
  3. Effects of a prolonged muscular inactivity on neurogenesis and neuro-muscular interaction
  4. New pharmacological approaches to the spinal muscular atrophy (SMA)
  5. Gene-environment interaction on the physiopathology of neuropsychiatric and neurodegenerative diseases
  6. Study of the beneficial effects of physical exercise.

 

DESCRIPTION OF THE RESEARCH TOPICS

1. Characterization and classification of leukotriene receptors and their physio-pathological role
This line of research is focused on the study, at a molecular level, of the GPCRs, with particular attention to the leukotriene and thromboxane receptors. Our interest has long been focused on the involvement of these receptors in the respiratory, cardiovascular and neurodegenerative diseases, on their classification, on the discovery of new drugs modulating their activities and on the discovery of new possible molecular targets. Furthermore, the lab is actively engaged in studying the possible cardiovascular protective effects of some drugs already used as anti-asthmatic and, more recently, on their possible role in COVID-19 syndrome (drug repurposing).
The lab is also interested on the functioning of particular P2Y receptors and their cross-talk with the leukotriene system.

2. Development and characterization of a new class of dualistic anti-inflammatory drugs
In collaboration with several Italian and European research groups, our lab has been long involved in the development and characterization of a new generation of anti-inflammatory drugs (bivalent molecules) with a better pharmacological and tolerability profile, both from the gastrointestinal and cardiovascular point of view, to be utilized in several chronic inflammatory diseases, including neurodegenerative diseases, and in selected forms of cancer.

3. Effects of prolonged muscle inactivity on neurogenesis and neuro-muscular interaction
The main aim of this project is to depict the effects of long physical inactivity on mammals' neurogenesis. With this line of research, we plan to continue our study about movement impairment in a healthy animal model in which is induced a reduction of gravity effects as those that represent in people who stay on wheelchair, in bed rest, or astronauts, particularly characterizing a gene/protein that acts as methylthiotransferase which expression is reduced in our mouse hindlimb unloading model and that also seems involved in mitochondria metabolism.

4. New pharmacological approaches to spinal muscular atrophy (SMA)
This study aims to search for new pharmacological approaches that can help SMA patients who have extended lower motor neuron degeneration and consequently cannot be treated with the recently approved drug for SMA. Using a mild SMA model or a cellular model (human SMA iPSCs), in which there is also a low capacity of movement, we plan to perform a comparative analysis with a model of reduction of movement (described in the previous line) with the intent of determining if also in those models there are similar gene expression alteration in particular for CDK5RAP1.

5. Gene-environment interaction in the physiopathology of neuropsychiatric and neurodegenerative diseases
The aim of this line of research is to investigate how genetic variations (BDNFVal66Met), environmental factors (stress, inflammation, diet, aging) and their interaction can alter the physiology and neuronal plasticity contributing to the onset of neuropsychiatric and neurodegenerative diseases. In particular, we are interest on the possible role of epigenetic mechanisms and oxidative stress. Moreover, we are involved in some studies aimed to investigate the comorbidity between neuropsychiatric and cardiovascular diseases.

6. Study of the beneficial effects of physical exercise.
The aim of this study is to understand the beneficial effects of physical exercise on brain plasticity and behavior. Our goal is to understand the possible physiological, neuroanatomical, molecular, and epigenetic mechanisms trigger the positive effects of exercise.
