CLINICAL NANOBIOCHEMISTRY GROUPS
The research of the group is focused into the design, synthesis, characterization and validation of red biotech systems and bio-inspired particles for treatment and diagnosis of human diseases, in particular those affecting the Central Nervous System
1) DESIGN OF BIOTECH NANOSIZED DEVICES FOR THE THERAPY OF CENTRAL NERVOUS SYSTEM DISEASES
This activity is finalized to the production of NPs able to cross the BBB for therapy and diagnosis of neurodegenerative diseases. The focus of the research is mainly on Alzheimer disease, on glioblastoma and on amyotrophic lateral sclerosis.
a) BBB crossing. NP made of different materials, e.g. Lipid based –liposomes, SLN/ polymeric/ Gold, are functionalized with an arsenal of ligands and tested to boost the crossing of BBB, mainly relying on receptor-mediated transcytosis mechanisms. Noteworthy, one line of research is exploiting the functionalization with blood-borne proteins . The efficacy of BBB crossing is followed either in vivo, on healthy mouse or TG mouse models or in vitro on cellular BBB transwell models. When designed for therapy purposes, NP are loaded with drugs , e.g. Doxorubicin or proprietary therapeutic peptides. However, the lab is also developing nanoparticles with original functionalizations that are able at the same time to promote the BBB crossing and interact with diseased cells.
b) Alzheimer disease. Within the FP7 European project “NAD” Nanoparticles for therapy and diagnosis of Alzheimer’s disease” coordinated by our group, we have developed multi-functionalized liposomes able to destroy Abeta plaques (present in Alzheimer diseased brain), or to prevent their formation and to restore the impaired cognitive function in transgenic mouse models of the disease. These NP have been patented and liposomes registered under the trade mark “Amyposomes”. Relying on the patents, a Spin off company, Amypopharma, has been founded (2015).
c) Glioblastoma multiforme, GBM. GBM also called grade IV astrocytoma is one of the most deadly brain tumors, with a short median patient survival and a very limited response to therapies. Our research aim is to specifically deliver chemotherapeutics to tumour cells, reducing their side effects, through smart bionanotech system. The results show that the product developed is able to reach the brain and to selectively trigger apoptosis in patientderived xenografts (PDXs) rodent model.
d) Amyotrophic lateral sclerosis (SLA). Despite more than 100 disease-modifying or neuroprotective agents have been tested in clinical trials, no cure has yet been found. Our research aim is to validate targeted lipid-based particles as carrier for HK1-Nterminal based peptide (NHK1), which is able to restore the cell viability of motor neuron-like NSC-34 cells. The results show that these particles are able to deliver NHK1 peptide across the BBB, preserving its ability to counteract the oxidative stress in a ALS cellular model.
e) Brain oxidative stress. Different neurological disorders are strongly interwined with reactive oxygen species (ROS) production and oxidative stress, which are considered
common effectors in the cascade of degenerative and pathological events in the brain. Our research aim is to test the antioxidant properties of Cerium oxide nanoparticles (CeONPs), thanks to theri ability known to act as strong, recyclable ROS scavengers by shuttling between Ce3+ (reduced) and Ce4+ (oxidized) oxidation states. The results show that CeONPs are able to strongly reduce the oxidative stress associated to beta-amyloid aggregates, typical hallmarks of Alzheimer’s disease
2) DESIGN OF BIOMIMETIC AND BIO-INSPIRED SYSTEMS FOR DIAGNOSIS AND THERAPY OF HUMAN DISORDERS
a) Bio-inspired nanoparticles for drug delivery. Nature offers a wide-range of sources of inspiration for the synthesis of more effective drug delivery platforms. Because the nano-bio-interface is the key driver of nanoparticle behavior and function, the modification of nanoparticles’ surfaces allows the transfer of biological properties to synthetic carriers by imparting them with a biological identity. Modulation of these surface characteristics governs nanoparticle interactions with the biological barriers they encounter.By mimicking these biological entities, we will learn how to more efficiently interact with the human body and refine our ability to negotiate with the biological barriers that impair the therapeutic efficacy of nanoparticles.
b) Bio-hybrid Nanoparticles to CROSS Biological Barriers. Incapability of effective cross-talk with biological environments has partly impaired the in vivo functionality of nanoparticles (NPs). Homing, biodistribution, and function of NPs could be engineered through regulating their interactions with in vivo niches. Inspired by communications in biological systems, endowing a “biological identity” to synthetic NPs is one approach to control their biodistribution, and immunonegotiation profiles. This synthetic-biological combination is referred to as biohybrid NPs, which comprise both i) engineerable, readily producible, and trackable synthetic NPs as well as ii) biological moieties with the capability to cross-talk with immunological barriers.
c) Protein corona on nanoparticles for personalized diagnostics. It is now well understood that once in contact with biological fluids, nanoscale objects lose their original identity and acquire a new biological character, referred to as a protein corona. Recently it has been shown that the protein corona is strongly affected by the patient’s specific disease. Therefore, the same nanomaterial incubated with plasma proteins of patients with different pathologies adsorb protein coronas with different compositions, giving rise to the concept of personalized protein corona.
d) Nanodiscs inspired to human discoidal lipoproteins (HDL). Plasma levels of high-density lipoproteins (HDL) and apoA-I, the major protein component of plasma HDL, inversely correlate with the development of many disorders, including cardiovascular diseases, diabetes, obesity, cancer, infectious diseases and neurodegenerative diseases. We recently found that apoA-I-based nanodiscs are able to cross the blood-brain barrier and strongly destabilize the conformation of Aβ aggregates, compared to spherical HDL.
3) ADVANCED IN VITRO CELLULAR MODELS OF BRAIN BIOLOGICAL BARRIERS
As a support of the activity finalized to the production of NPs able to cross the BBB for therapy and diagnosis of neurodegenerative diseases, in vitro transwell cellular models of the blood brain barrier (BBB) or the blood cerebrospinal- fluid barrier (BCB) are currently available at UNIMIB, in order to minimize the need for animals in high throughput preclinical studies. The models allow to evaluate quickly and in a reproducible way the predictive in vivo permeability of compounds and nano-based drug delivery systems under development and to identify specific transport mechanisms, for neurotoxicity and neuroprotection studies. Examples of our models are based on rat brain endothelial cell lines, rat choroidal epithelial cell lines and human micro-endothelial cell lines.
The development of realistic in vitro blood-brain barrier (BBB) models that recapitulate the physiological parameters and molecular aspect of the neurovascular unit (NVU) is of fundamental importance not only in CNS drug discovery but also in translational research. We have different BBB platforms, starting from unicellular models to advanced multicellular models of functional BBB in vitro. We are also working on advanced 3D printing technologies for engineering BBB models, which use is now fast expanding among researchers.
