IRSS Webinar: Introduction to Extracellular Vesicles and their Role in Respiratory Toxicology

Speakers:
Angelica Ortiz, PhD, New York University Grossman School of Medicine
Gregory Smith, PhD, University of North Carolina at Chapel Hill

Description: Extracellular vesicles (EV) are different types of lipid-bound vesicles secreted into the extracellular space from almost all host cells and are found widely distributed throughout the body. They have recently been found to play a myriad of roles in normal human physiology, including intracellular communication. This IRSS-sponsored webinar will provide an introduction to EVs and expand upon their role in pulmonary events in relation to respiratory toxicology. Dr. Angelica Ortiz will provide a background and overview of EVs including their origin, composition and purpose, as well as their role in signaling and mediation of toxicological effects. Dr. Gregory Smith will provide a case study of how ozone exposure alters EV release and EV miRNA expression, leading to immune cell dysfunction and respiratory inflammation. We believe this webinar will be of great interest to all respiratory and inhalation toxicologists, researchers of pulmonary infection and those toxicologists interested in mechanisms, translational medicine, drug discovery or exposure assessment, among other multi-disciplinary groups.

IRSS Webinar: Role of Inhaled Pollutants in Risk of Pathogenic Infection

Speaker:
Stephania Cormier, PhD, Wiener Chair Professor at University of Louisiana
Sarath Raju, MD, MPH, Assistant Professor of Medicine at Johns Hopkins University school of Medicine

Description: Environmental pollution and inhaled toxicants are prevalent in every society, and it is understood that such pollutants may predispose or exacerbate infection in the lung. This IRSS sponsored webinar will focus on the Impact of inhaled toxicant exposure on response to infection.

Dr. Sarath Raju will provide an epidemiological overview of air pollution as an example of an inhaled pollutant that can lead to increased susceptibility of infection. Dr. Stephania Cormier will present on a mechanistic viewpoint on early life exposure to inhaled pollutants and immune modulation leading to increased infection susceptibility. We believe this webinar will be of great interest to inhalation toxicologists and researchers of pulmonary infection.

IRSS Webinar: Intersection of Environmental Justice, Air Pollution and Climate Change: We are All in this Together

Speakers:
George Thurston, ScD, Professor, Departments of Environmental Medicine and Population Health, NYU Grossman School of Medicine
Jada Brooks, PhD, MPSH, RN, FAAN Assistant Professor, University of North Carolina at Chapel Hill School of Nursing

Description: A variety of factors such as climate change, natural disasters, occupations, and other societal activities can cause us to be exposed to inhaled toxicants. We are all at risk, but it has become evident that the resulting impacts are often disproportionate, whereby the health of specific populations and/or marginalized communities are most adversely affected. This webinar on Environmental Justice features two expert panelists who will provide insight on how various groups are differentially impacted from the perspective on inhalation-based toxicity. Dr. George Thurston will introduce the nature, complexities, and disparities in how different communities are subject to greater environmental risk and health impacts. Dr. Jada Brooks will provide a case-study focusing on American Indians and women of color, and how they are disproportionality susceptible to inhaled pollutants.

IRSS Webinar: Microplastics and Pulmonary Risk: Environmental Prevalence, Exposure and Mechanisms of Pulmonary Action

Speakers:
James McGrath, PhD, Professor of Biomedical Engineering, University of Rochester
Eliseo Castillo, PhD, Assistant Professor, Molecular Genetics and Microbiology University of New Mexico

Description: As a rapidly growing field of study, plastics in the environment are being assessed for their impact on ecosystems and their potential impact on human health. Microplastics (plastic less than 5 mm in size) in the environment consist of various types, prevalence and by extension, risk of inhalation and/or the toxicological impact on the respiratory system. This webinar will have two panelists covering different aspects relevant to this topic. Dr. James McGrath will review the different types of microplastics and their prevalence in the environment (e.g., bodies of water) and refer to those of inhalation concern. Dr. Eliseo Castillo will discuss the mode of action-based toxicity of these particles on a cellular level and how they relate to inhalation or respiratory toxicology. The webinar will provide the audience with the current understanding of the concerns of microplastics in the environment and the potential consequences of inhalation exposures or system effects on the respiratory system.

IRSS Webinar: Inhalation Toxicology of COVID-19

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel coronavirus that causes coronavirus disease 2019 (COVID-19). Classified as a pandemic by the World Health Organization, it has impacted nearly every country and has caused hundreds of thousands of deaths. A COVID-19 infection is characterized by flu-like symptoms, progressing in some cases to acute respiratory distress syndrome and other clinical manifestations. This webinar will review COVID-19 and the pediatric population: risk factors for severe infection and hospitalization (Dr. Matthew McGraw), and then examine the inhalational exposures as potential risk factors for COVID-19 in adolescents (Dr. Ilona Jaspers). The webinar will review the current understanding of the COVID-19 respiratory toxicities to date.

IRSS Webinar: Novel Applications for a Non-invasive Sampling Method of the Nasal Mucosa in Inhalation Toxicology

Speakers: Meghan Rebuli, PhD and Ilona Jaspers, PhD, University of North Carolina, Chapel Hill, NC

Chairs: Irfan Rahman, PhD, Professor, University of Rochester, Rochester, NY
Matthew J Campen, PhD, MSPH, Regents’ Professor of Pharmaceutical Sciences Chair,
Environmental Health Signature Program KL2 Program Director University of New Mexico, Albuquerque, NM

The webinar entitled, “Non-invasive Nasal Mucosa Sampling Technique: Uses in Toxicology,” presents and demonstrates the non-invasive nasal mucosa sampling technique described in Rebuli et al (2017) Novel applications for a non-invasive sampling method of the nasal mucosa. Am J Physiol Lung Cell Mol Physiol. doi: 10.1152/ajplung. 00476.2016. This method was specifically designed to collect concentrated and replicable samples from the nasal mucosa and improve on the current gold standard, nasal lavage. This method because of its quick and non-invasive nature is easily adaptable to epidemiological studies as a biomarker collection technique, field studies because of its stable capture of proteins, and in the clinic in a variety of populations. This webinar will allow us to share this technique with others in the field of respiratory toxicology and potentially facilitate new translational research.

The second part of the webinar will describe current research using the technique and innovative ways to utilize the technique to answer research questions. Examples include detection of low abundance cytokines and chemokines, detection of viral particles, and analysis of nasal microbiome, protease activity, and proteomics.

IRSS Webinar: 3D Organ-on-Chip Framework and Translational Research by Environmental Exposures in Inhalation Toxicology

Chair: Irfan Rahman, PhD, Professor, University of Rochester, Rochester, NY; and Matthew J Campen, PhD, MSPH, Regents' Professor of Pharmaceutical Sciences Chair, Environmental Health Signature Program KL2 Program Director University of New Mexico, Albuquerque, NM

Speaker: Kambez H. Benam, Assistant Professor, University of Colorado, Aurora, CO

No Recording Available for this Webinar

Development of new therapeutics for pulmonary disorders, and advancement in our understanding of inhalational toxico-pathology have been significantly hindered by challenges to study organ-level complexities of human lung in vitro. Moreover, clinical relevance of widely used animal models of respiratory diseases such as chronic obstructive pulmonary disease (COPD), which poses a huge public health burden, is questionable. Here, we applied a tissue microengineering approach to create a human lung “Small Airway-on-a-Chip” that supports full differentiation of a pseudostratified mucociliary bronchiolar epithelium from normal or diseased donors underlined by a functional microvascular endothelium.

Exposome is defined as the measure of all the exposures of an individual in a lifetime and how those exposures relate to health (CDC). The exposome encompasses life-course environmental exposures (including lifestyle factors) from the prenatal period onwards. It is the cumulative measure of environmental influences and associated biological responses throughout the lifespan, including exposures from the environment, diet, behavior, and endogenous processes. This webinar will provide the state-of-the-art approaches as well as the recent developments on exposomes and exposomics in inhalation toxicological sciences. Further, it will provide the information on the role of the exposome and genome (exposomics) and their interplay in life-course health and disease by integrating inhalation toxicology.
