Molecular and Cellular Dissection of the New Food Allergy Disease Eosinophilic Esophagitis
Dr. Marc Rothenberg, MD, PhD
2:00pm CDT 
Watch in Our Members Video Archive 


Since the original description of eosinophils, clinicians and scientists have been struck by the number of disease associated with selective eosinophilia, in the blood and/or tissues. Over the past several decades, I have had the privilege of helping to elucidate the mechanisms that explain eosinophilia, which in turn has contributed to a new class of drugs, referred to as anti-eosinophil therapy. This has provided a gratifying opportunity to better treat patients and a scientific means to define the role of this enigmatic cell in a variety of diseases, starting with diseases thought to be primary eosinophilic diseases, such as eosinophilic esophagitis (EoE). Herein, I will review pathways involved in regulating eosinophilia starting with the initial description of eosinophilopoeitins with a focus on eosinophil survival factors and their importance in human diseases. Molecular cloning and characterization of the eotaxins will be reviewed and a mechanism for cytokine regulation of eosinophilia will be presented. There will be a focus on the prototypic tissue eosinophilic disease, EoE, concentrating on the molecular, genetic, and cellular bases of disease pathogenesis, and their implications for emerging therapeutics and diagnostics. The genetic and environmental factors that contribute to risk for EoE—particularly early-life events will be discussed. A key role for epithelial inflammatory pathways (production of eotaxin-3 [encoded by CCL26]), impaired barrier function mediated by loss of desmoglein-1 and anti-protease surveillance mechanisms will be presented. Breakthroughs in understanding disease susceptibility with a focus on genome wide association studies and whole exome sequencing data will be presented. Genetic susceptibility involving common variants at 5q22 (TSLP) and 2p23 (CAPN14), gene-gene interactions (between atopy genes and EoE specific genes), and gene-environment interactions will be presented. A mechanistic explanation for the tissue specific eosinophilia seen in EoE will be iterated. I will leave the message that substantial progress has been made in elucidating the molecular and genetic regulation of eosinophilia, providing opportunities for better treating eosinophilic disorders, and better understanding the function of this enigmatic cell in a variety of diseases.

Regulatory Natural Killer Cell Responses Shape the Outcome of Co-Infection by Lung and Gut Pathogens
Dr. Laurel L. Lenz, PhD
2:00pm CDT
Watch in Our Members Video Archive 


Pulmonary and systemic viral infections increase susceptibility to co-infection by pulmonary bacterial pathogens and are a leading cause of human deaths. I will discuss recent data demonstrating the dramatic impact of lung infection on susceptibility to co-infection by an oral bacterial pathogen. I will further discuss immune mechanisms contributing to increased invasive infection by orally encountered pathogens. These studies underscore the connectivity of gut and lung mucosae in determining the immune response to infection and overall resistance to disease.

Injury and Repair of the Alveolar Epithelial Barrier
Rachel Zemans, MD
2:00pm CDT
Watch in Our Members Video Archive


Several acute and chronic lung diseases result from ineffective regeneration of the alveolar epithelium after injury. We have no therapeutic options to promote regeneration, in part because of our limited understanding of the underlying mechanisms. The alveolar epithelium consists of type 1 and type 2 alveolar epithelial cells (AECs). AEC1s play a critical role in barrier function since they cover >95% of the alveolar surface and facilitate efficient gas exchange by virtue of their exquisitely thin morphology. However, AEC1s are highly susceptible to death during lung injury due to a variety of insults. Surviving AEC2s are the principal progenitor responsible for regenerating the injured alveolar epithelium. AEC2s proliferate to replace lost cells, then differentiate into AEC1s to restore normal alveolar architecture and function. Impaired regeneration results in lung disease, including pulmonary fibrosis. We have identified mechanisms underlying AEC2 proliferation and AEC2-to-AEC1 differentiation, including a novel AEC2-AEC1 transitional cell state that emerges transiently during normal regeneration but persists in pulmonary fibrosis. The role of immune cells in both promoting physiologic regeneration and impairing regeneration during disease pathogenesis will also be discussed. We hope these findings may eventually lead to novel therapies to promote normal regeneration and ameliorate lung disease.

Mucosal Therapies: Resolution Responses in Oral Cavity
Thomas Van Dyke DDS, PhD
8:00am CDT 
Watch in Our Members Video Archive


Periodontitis, the most common inflammatory disease of man, is an infectious/inflammatory disease associated with dysbiosis of the commensal oral microbiome. Importantly, recent studies demonstrate a relationship between oral infectious/inflammatory conditions, in particular periodontal disease, and risk for systemic diseases, including cardiovascular disease and Type 2 diabetes. Resolution of inflammation is an active, receptor agonist mediated, well-orchestrated return of tissue homeostasis, not inhibition of proinflammatory pathways. Preclinical studies have demonstrated that specialized proresolving lipid mediators (SPMs) are potent when topically applied in the prevention and treatment of periodontitis. A Phase 1 clinical trial in humans presented no safety concerns for oral topical applications. Characterization of the molecular basis for regulation of inflammation has changed our understanding of the relationship between infection and inflammation in the oral cavity. Early efficacy data in humans reveals that a specific lipoxin analog reduces gingivitis and established periodontitis. These first in human studies demonstrate safety and potential efficacy of a pro-resolving mimetic for the treatment of periodontal diseases in man.

  1. Understand active resolution of inflammation pathways.
  2. Understand the pathogenesis of periodontitis and treatment options.
  3. Appreciate the potential of new therapeutics based on active resolution of inflammation pathways.

Lung Resident Immunity to Respiratory Viruses
Donna Farber, PhD
2:00pm CDT 

Due to the cutting-edge COVID-19 research presented, a recording is not available for this presentation.
  • Define major components of lung resident immune cells, including tissue-resident memory t cells
  • Mechanisms for protection in mouse models of influenza infection
  • Lung resident and systemic immunes responses in severe COVID-19
Donna L. Farber, Ph.D. is the George H Humphreys, II Professor of Surgical Sciences (in Surgery) and Professor of Microbiology and Immunology at Columbia University. The focus of Dr. Farber’s research is on adaptive immunity, particularly to virus infections and how T cell differentiate and generate long-term immunological memory in diverse tissues sites. Dr. Farber’s laboratory identified subsets of tissue-resident memory T cells in the lung that mediate protective immunity to respiratory virus infection and has led an initiative in translational immunology to dissect human immune responses in tissues throughout the body, in multiple mucosal and lymphoid tissues from individual organ donors of all ages. She has also made important contributions to understanding how T cells seed tissues and mediate responses to viruses during different life stages including infancy. Dr. Farber leads NIH/NIAID-funded Program grants on human immunity, anti-viral responses and is part of the Human Immunology Project Consortium (HIPC), as well as the NIH/NHLBI consortium on human lung aging. In addition to the NIH, her research is supported by the Helmsley Charitable trust and the Chan-Zuckerberg seed network for the Human Cell Atlas. She has over 140 publications and has served on numerous advisory committees for the NIH, American Association of Immunologists, Federation of Clinical Immunology Societies and others.
