Ultrastructural morphology (particularly on mitochondrial cristae) by HRSEM, mitochondrial physiology.
Currently, two projects are developing. The first is on liver mitochondrial bioenergetics in an animal model of hepatic steatosis and NASH. Evaluation of liver mitochondria’s oxidative efficiency of the OXPHOS (oxidative phosphorylation) complexes in rat fed with a hyperlipidic diet and controls fed with an isocaloric one is pursued by means of a Clark-type electrode. The associated variations in mitochondrial cristal structure have been searched by HRSEM and TEM, too.
The second project is on the effects of long-term diabetes (more than 4 months) on the cardiovascular system of female rats. This project will evaluate the changes in connective tissue composition of the portal vein and aorta and of the left ventricle and will relate them with the physiology of contractility of portal vein and of the heart’s papillary muscle contractile force (the latter two done by the other Unit). Variations in mitochondria OXPHOS efficiency in right and left ventricle will be associated with electron microscopy morphological changes of mitochondria in the same areas. Mitochondrial efficiency will be also associated to the extent of mitochondrial complexes associations, namely respirosomes or supercomplexes.
Collaborating to other projects involving the assessment of the presence of receptors, belonging to the non-adrenergic non-cholinergic system, not yet identified in human salivary glands, by immunoblotting and immunohistochemistry technique.
Past interests dealt with adrenal gland mitochondrial cristae 3D morphology, Candida albicans ultrastructure, cell biology studied by means of fluorescent probes (study of the mitochondrial potential, of ROS production, etc.). First research interest was in the Neuroscience field, by investigating on alcohol and nicotine addiction in animal models.
