Brian Southern, MD

Associate Staff
Location: Cleveland Clinic Main Campus

Research


Biography

Dr. Southern is a Staff Physician in the Respiratory Institute and Assistant Professor of Molecular Medicine at the Cleveland Clinic Lerner College of Medicine of Case Western Reserve University. He has a secondary appointment as an Associate Staff Scientist in the Lerner Research Institute Department of Pathobiology, where his research focus is Idiopathic Pulmonary Fibrosis (IPF). Dr. Southern explores how fibroblasts and myofibroblasts (the scar-producing cells in IPF) interact with lung tissue matrix to propagate fibrosis. He has identified that the molecular motor protein, non-muscle myosin II, is a critical molecule driving fibrosis, and is further characterizing the myosin II pathway in fibroblasts in order to identify novel targets to halt fibrosis in patients with IPF.

In addition to his research activities, Dr. Southern conducts an outpatient clinic where he cares for patients with interstitial lung disease and sarcoidosis, and he is a co-investigator on a number of clinical trials for patients with IPF. He serves as the physician leader for the Cleveland area Pulmonary Fibrosis Support Group.

Research

  • Overall areas of interest  
    • Pulmonary fibrosis, idiopathic pulmonary fibrosis, mechanotransduction, wound repair, fibroblast biology, myofibroblast transdifferentiation, non-muscle myosin biology

 

  • Tools and expertise of the lab
    • Ex vivo normal and fibrotic lung assay systems (Rahaman JCI 2014, Grove JBC 2014, Southern JBC 2016, Mao Gut 2021)
    • Mouse models of pulmonary fibrosis (Rahaman JCI 2014, Southern JBC 2016)
    • Wound repair models (Ding Am J Pathol 2013, Grove JBC 2014, Southern JBC 2016)
    • Traction force microscopy (Southern JBC 2016, Grove Sci Signal 2019)
    • Mechanotransduction assays (Rahaman JCI 2014, Scheraga Immunol 2016, Southern JBC 2016, Grove Sci Signal 2019, Scheraga Immunol 2020)
    • Isolation of fibroblasts and lung tissue from patients with pulmonary fibrosis (Southern JBC 2016)

 

  • Examples of collaborators
    • Thaddeus Stappenback/PAI-I inhibition in pulmonary fibrosis
    • Andre Ivanov/Non-muscle myosin II signaling
    • Florian Reider/Cell migration in IBD and pulmonary fibrosis
    • Anne Bresnick, Einstein College of Medicine/S100A4 protein signaling
    • Daniel Tschumperlin, Mayo Clinic/Mechanotransduction pathways

 

  • Lab discoveries
    • Identified non-muscle myosin II as a critical signaling molecule in the pathogenesis of  pulmonary fibrosis (Southern JBC 2016)
    • Discovered TRPV4 as a novel regulator of mechanotransduction in pulmonary fibrosis and lung injury and infection (Rahaman JCI 2014, Scheraga Immunol 2016, Grove Sci Signal 2019, Scheraga Immunol 2020)
    • Developed new ex vivo assays using normal and fibrotic lung to study fibroblast signaling (Rahaman JCI 2014, Southern JBC 2016)
    • Identified the role of the urokinase receptor in hypermotile fibroblasts in pulmonary fibrosis (Grove 2014)

 

  • How could these discoveries help patients?
    • New classes of therapies for idiopathic pulmonary fibrosis
    • Novel ways to study fibrosis that may impact numerous diseases
    • New ways to targeting mechanotransduction signaling as a treatment for fibrotic diseases
    • Better understanding of disease mechanisms in pulmonary fibrosis
