Pezzanite Research Team

Our research program can be divided programmatically into three focus areas in the field of comparative orthopedics and regenerative medicine: study of pathological responses in osteoarthritis, elucidation of the role of the gut microbiome in orthopedic conditions, and the development of cellular and immunomodulatory approaches to treat musculoskeletal disease. Our laboratory’s work spans bench to bedside, integrating basic molecular-cellular biology techniques and preclinical animal models of orthopedic conditions to inform clinical interventions in veterinary and human patients. The overall goal is to pursue a basic study of musculoskeletal homeostasis and disease to develop therapeutic strategies addressing key orthopedic challenges including osteoarthritis and multidrug-resistant infection.

The Pezzanite research lab is part of the:

Collaborations

research project

Transcriptomic response in post-traumatic osteoarthritis

This study will highlight the role that cells of the immune system play to contribute to disease progression of osteoarthritis toward the goal of developing treatments for each stage of disease.

research project

Role of the gut microbiome and bacterial metabolites in osteoarthritis

These studies will further our understanding of the mechanistic underpinnings of microbiome-skeletal interactions in disease progression.

research project

Identification of optimal senolytic drug therapies to treat osteoarthritis

These studies will investigate and compare biological activity of senolytic drugs to selectively induce apoptosis and modulate senescence associated secretory phenotype for improved osteoarthritis treatment.

research project

Translational musculoskeletal research

These studies seek to promote limb restoration and functional mobility, with translational application to both veterinary and human patients.
