The Challenge & Our Mission
The Challenge
Retinitis Pigmentosa (RP) is a group of inherited retinal diseases affecting approximately 1 in 4,000 people. It causes progressive photoreceptor cell loss, leading to irreversible vision impairment and often complete blindness. Despite decades of research, there is still no generalized drug therapy that can halt or reverse the disease's progression.
Our Mission
The ReGenAI project proposes an innovative approach to address this challenge. Our mission is to leverage cutting-edge artificial intelligence and single-cell genomics to identify existing, approved drugs that can be repurposed to treat Retinitis Pigmentosa, with the goal of significantly accelerating the journey from scientific discovery to clinical application.
A Three-Phase Strategy
Decoding the Disease
We generate a high-resolution "genetic fingerprint" of RP using single-cell RNA sequencing on the RD10 mouse model.
AI-Powered Discovery
Our AI model screens thousands of drugs from the LINCS database to find molecules that can "reverse" the disease fingerprint.
Pre-clinical Validation
The top drug candidates are tested on RD10 mice to confirm their efficacy in improving retinal function and structure.
How Our AI Works
Input 1: Disease Data
scRNAseq profiles from RD10 mouse retinas
Input 2: Drug Data
LINCS database of drug-induced gene expression
Adversarial AI Model
The model uses a shared encoder and an adversarial classifier to learn the true biological signature of RP, ignoring dataset-specific noise, and predicts which drugs can reverse it.
Meet the Team
This project is driven by a synergistic collaboration between two highly specialized research units, led by principal investigators with complementary expertise.
Biomedical Unit — UNINA
This unit conducts the core biological experiments of the project. Leveraging its state-of-the-art Genomic and Animal Facilities (TIGEM), the team manages the animal models, generates all the single-cell transcriptomic data, and performs the in-vivo validation of the drug candidates identified by the AI, using advanced functional and morphological assays (ERG, OCT).
Computational Unit — UNISANNIO
This unit manages the project's computational research. With access to a high-performance Superdome server, the team develops and trains the sophisticated AI model. They are responsible for analyzing the complex single-cell data, prioritizing drug candidates through large-scale virtual screening, and performing the final bioinformatic analysis of treated samples.
Principal Investigators
Prof. Michele Pinelli
Associate Professor of Medical Genetics
As the project's PI, Prof. Pinelli coordinates the biomedical and computational efforts. His research focuses on the transcriptomics of the human retina and the diagnosis of rare genetic diseases. His expertise is fundamental for generating high-quality biological data and ensuring the clinical relevance of the project's findings.
Prof. Francesco Napolitano
Associate Professor of Bioinformatics
Prof. Napolitano leads the development of the project's computational strategy. As a Computer Scientist, his work centers on creating innovative machine learning and deep learning models for computational drug discovery. He develops the novel AI tools and analytical pipelines that are essential for identifying therapeutic candidates from complex genomic data.
