RESEARCH AREA AND TRANSLATIONAL RESEARCH

The function of the kidney depends on the precise organization and coordination of more than 30 cell types, forming the functional units called nephrons. A variety of clinical conditions, such as diabetes, drug toxicity, and autoimmune diseases, can damage kidney cells and alter the balance necessary for the organ to properly function. Since the kidney loses the ability to generate new nephrons after birth, the maintenance of renal function after kidney injury depends on the compensatory adaptation of the remaining nephrons, and the ability of the kidney to repair damaged nephrons. Unfortunately, this process is often incomplete and can result in the persistence of altered cells and a dysfunctional tissue architecture, which contribute to the progression of renal disease towards renal failure. In this stage the kidney damage is irreversible, and the patient rely on dialysis or kidney transplant to survive. Our research aims to characterize and better understand the biological processes of kidney repair. The goal is to support functional tissue regeneration processes and prevent the progression to chronic kidney disease.

RESEARCH METHODS
MOUSE MODELS

Our lab uses phenotypically and genetically characterized mouse models of transition of AKI to CKD, which mimic clinical conditions and allow to investigate adaptive and maladaptive repair.  Transgenic mice can be implemented in our experimental strategy to perform functional validation of the identified targets.

TRANSLATIONAL MODELS

We focus on selected patient cohorts clinically well-characterized that have specific features enabling the study of precise aspects of the processes of kidney injury and repair.

SINGLE CELL TRANSCRIPTOMICS

Our lab established single-cell RNA sequencing based on the Drop-seq technology developed by 10x genomics to analyse frozen samples obtained from mouse models and importantly for our translational interest, from patients with AKI.

BIOINFORMATICS AND ARTIFICIAL INTELLIGENCE

Our laboratory employs computational approaches to analyse single-cell RNA sequencing data, investigate the cellular composition and the molecular responses in kidney repair. In collaboration with the Institute Dalle Molle of Artificial Intelligence (IDSIA), our lab is developing a computational pipeline which applies machine learning and statistical methods to exploit the relevance of single-cell RNA sequencing data in clinical settings.

BRIEF CV

Pietro Cippà obtained his MD degree in 2007 from the University of Zurich. He worked as a clinical and research fellow from 2009 to 2015 at the University Hospital Zurich, where he obtained his PhD, his clinical specialization in internal medicine and in nephrology and the venia legendi. From 2016 to 2018 he worked at the Broad Center for Regenerative Medicine and Stem Cell Biology at the University of Southern California, Los Angeles (USA). Since 2018 he has been the chief of the division of Nephrology in Lugano and the group leader of the nephrology research group. Since 2020 he has been the Medical Director of the Department of Medicine of the EOC.
