Biography

Dr. Alan Dardik is a surgeon-scientist who harnesses the power of molecular biology to achieve a modern understanding of vascular disease, and then use the basic science laboratory to ultimately benefit patients with vascular diseases.

Dr. Dardik trained at Yale, the University of Pennsylvania, and the Johns Hopkins Hospital before his appointment to the Yale faculty in 2001. Dr. Dardik focuses his clinical practice on teaching at the VA Connecticut, where he was formerly the Chief of Vascular Surgery and currently serves as the Chief of Surgery. Dr. Dardik has won the C. Elton Cahow Award for Outstanding Faculty Teaching from Yale’s Department of Surgery and the Faculty Teaching Award from St. Mary’s Hospital. Dr. Dardik has served Yale’s Department of Surgery as a Vice Chair of Faculty Affairs, as well as Interim Division Chief of Vascular and Endovascular Surgery.

The Dardik laboratory studies the healing and function of blood vessels, fistulae and vessel patches that are used in patients having vascular surgery. The laboratory is trying to understand the fundamental molecular mechanisms by which vein graft adaptation and arteriovenous fistula maturation result in positive remodeling and successful adaptation to the arterial environment, yet often proceed, in the long-term, to neointimal hyperplasia and failure. The laboratory also studies novel methods to deliver stem cells to diabetic wounds. The laboratory is funded from the NIH as well as Yale's Department of Surgery.

Dr. Dardik currently serves as the Editor-in-Chief for the translational science journal JVS-Vascular Science; he is the past President of the New England Society for Vascular Surgery, the Association of VA Surgeons as well as of the International Society for Vascular Surgery. Dr. Dardik has run several national and international meetings, including the Society for Vascular Surgery Vascular Research Initiatives Conference, and has served on numerous peer review committees including review for the NIH, the VA, and Vascular Cures. Dr. Dardik has edited several textbooks including “Vascular Surgery: A Global Perspective” and “Stem cell therapy for vascular diseases.”

Research

Overview

The Dardik laboratory uses modern molecular techniques to study the diseases and therapeutics that vascular surgeons care for in their patients. As part of Yale’s Vascular Biology and Therapeutics program, we take advantage of our rich collaborative environment to push our field forward, focusing on basic and translational research that is relevant to our patients.

A major focus of our laboratory is to understand the healing and function of blood vessels and synthetic blood vessel substitutes and patches that are used in vascular reconstruction. We are currently trying to understand the fundamental molecular mechanisms by which vein graft adaptation and arteriovenous fistula maturation result in positive remodeling and successful adaptation to the arterial and fistula environments, yet often proceed, in the long-term, to neointimal hyperplasia and graft failure. We are focusing on the role of vascular identity in controlling the response to vascular intervention; the laboratory made the original observation that vein graft adaptation is associated with diminished Eph-B4 expression without increased Ephrin-B2 expression, e.g. vein grafts lose venous identity without gaining arterial identity (Kudo et al., ATVB 27:1562, 2007; Muto et al., J Exp Med 208:561, 2011). However, arteriovenous fistula maturation is characterized by retention of venous identity with gain of arterial identity (Protack et al., Sci Rep 7:15386, 2017). We are currently exploring downstream mechanisms by which vessel identity regulates vessel remodeling and the success or failure of vascular therapeutics (Sadaghianloo et al., Ann Vasc Surg 41:225, 2017) as well as the role of the extracellular matrix in controlling vascular remodeling (Kuwahara et al., ATVB 37:1147, 2017). This work has led to the new RADAR procedure that shows improved outcomes compared to the conventional radial-cephalic AV fistula (Bai & Sadaghianloo et al., Science Transl Med 12(557):eaax7613, 2020). We have recently shown the importance of the immune system in venous remodeling during AVF maturation (Matsubara et al, ATVB 41:e160, 2021) including the presence of a PD-L1 mechanism (Matsubara et al, ATVB epub Oct 21, 2021).

Studying mechanisms of vascular remodeling has also led us to examination of vascular patch remodeling, including demonstration that patches heal by infiltration of vascular stem cells according to their environment (Li et al., PLoS ONE 7:e38844, 2012; Bai et al., Physiol Rep 4:e12841, 2016; Bai et al., J Biomed Mater Res A 105:3422, 2017). This work led to the first description of a mechanism of pseudoaneurysm formation after patch angioplasty (Bai et al., ATVB epub Nov 16 2017) as well as description of a novel drug delivery system (Bai et al., Sci Rep 7:40142, 2017). We also study remodeling of tissue engineered vascular grafts using both in vivo and in vitro models.
