Christine Freeman Basmajian, PhD

Research Assistant Professor, Department of Internal Medicine
Deputy Associate Chief of Staff - Research, VA Ann Arbor Healthcare System

Degrees and Fellowships

  • PhD, University of Michigan, 2006
  • Pulmonary and Critical Care Research Fellow, University of Michigan, 2009 

Research Interests

The long term goal of my research is to improve understanding of how the immune system contributes to Chronic Obstructive Pulmonary Disease (COPD) progression. I am particularly interested in the role of CD8+ T cells, NK cells, and NK T cells in COPD pathogenesis and providing insight into the mechanisms by which these cells could be causing lung destruction. For these studies, we use human lung tissue from clinically-indicated surgical procedures. We have developed innovative techniques that allow us to directly study the response of cytotoxic cells in vitro and correlate this to patient data.

John Erb-Downward, PhD

Assistant Research Scientist, Department of Internal Medicine 

Degrees and Fellowships

  • BS, Cornell University, 1996
  • PhD, Microbiology and Immunology, University of Michigan, 2005
  • Fellowship, Pulmonary & Critical Care Medicine, University of Michigan, 2009

Research Interests

Dr. Erb-Downward's investigative career has focused on the communication between host and microbe, including the microbiome. Some of my initial publications identified the ability of a pathogenic fungus, Cryptococcus neoformans, to produce immunomodulatory prostaglandins. These investigations demonstrated that through small molecules, microbes were capable of communicating directly with mammalian host cells in the same language that the host cells use to communicate with each other. This research led me to study microbial ecology and the interactions between the host and the indigenous microbiota of the lung. Broadly, my current research involves elucidating the role of the lung microbiome in lung disease through an examination of the bacterial communities present in the lungs of healthy individuals and those with lung disease (COPD, IPF, lung cancer, ALI and after lung transplantation). To characterize these bacterial communities I use culture-independent methods such as high-throughput 454 pyrosequencing of the bacterial 16S rRNA gene along with multivariate visualization and analysis tools to identify community differences. I am working with several different investigators combining microbial community data with clinical data to determine which bacterial communities drive the differences between health and disease, and which host factors correlate with community differences. 

Dr. Erb-Downward is a member of Dr. Gary Huffnagle's lab team.

Research Interests

The dynamic interactions between cancer cells and the tumor microenvironment (TME) foster tumor growth, metastasis and may influence the outcome of a given therapy. It is apparent that understanding the unique molecular circuitry of the TME is essential for successful control of a malignancy. In spite of being the leading cause of cancer death world-wide, the nature and the role of TME in lung tumor progression and metastasis is poorly understood. Towards this goal, our efforts are focused on delineating basic mechanisms and interactions in lung TME particularly that are mediated by the cytokine TGF-beta, and to develop therapeutic strategies to disrupt these interactions. Projects that we are currently pursuing are 1) targeting TGF-beta mediated Epithelial-mesenchymal transition for prognosis and therapy of lung cancer; 2) regulation of immune evasive mechanisms in tumor microenvironment; and 3) restoring tumor suppressive functions of TGF-b.

Research Interests

Scientific interest of our group focuses on the host-pathogen interaction at the interface of the adaptive and innate immunity. The effects of these interactions on the development of protective responses against fungal and bacterial pathogens are a common theme of these studies. Following areas of investigation have been established: Mechanisms involved in pathogenesis of Cryptococcus neoformans infection and persistence of this microbe are main focus of our work. The interplay between the host and microbial factors especially, the role of microbial factors, urease, laccase-lac1, ena1, pyk1, rub1, vad1 and Hsp70 homologue Ssa1 on different aspects of innate and adaptive host response. Studies of macrophage M1/M2 polarization and their plasticity in the context of cryptococcal infection Alternative activation of macrophages promotes persistence of C. neoformans we look into the mechanisms that promote and or prevent the alternative activation. These mechanisms include cytokines, direct effects of cryptococcal virulence factors, and pattern recognition receptors such as TLR9. We study how these factors affect macrophage biology in context of cryptococcal infection. Studies of the role of macrophage lysosomal damage and its effects on macrophage fungicidal activities and cryptococcal antigen cross-presentation. Differential outcomes of infections are observed in various strains of mice infected with C. neoformans. We are interested in inheritance of these factors and the evaluation how genetic differences affect phenotype of the immune response to C. neoformans. Mechanisms modulating the development of the adaptive immune responses to C. neoformans, particularly the role of cytokines, chemokines and growth factors including TNF-alpha and IL-12, CCL7 (MCP-3), CCL3 (MIP-1 alpha) and GMCSF. Effects of these factors during the early responses (dendritic cells and macrophages) and their subsequent effects on T cell response polarization are studied.

Marc Peters-Golden, MD

Marc Peters-Golden, MD, conducts research on the mechanistic aspects of lung inflammation, antimicrobial defense, and fibrosis. Using tools of molecular and cell biology, cells from diseased patients, as well as animal models of disease, we focus on the functions of two key cells in the lung, macrophages and fibroblasts, and how these cells interact with each other and with neighboring epithelial cells. Ongoing current projects include: 1) the role of extracellular vesicles in cell-cell communication in lung health and disease, and 2) cellular programs dictating aberrant fibroblast activation in pulmonary fibrosis. We are currently examining disease states including asthma, cigarette smoke-induced inflammation, lung cancer, lung infection, and idiopathic pulmonary fibrosis. Our ultimate goal is to gain novel insights into lung homeostasis and disease pathogenesis, and to identify new strategies for therapeutic targeting. The laboratory consists of a highly interactive and collaborative group of students as well as M.D. and Ph.D. postdoctoral trainees from around the world.
