Traditional submerged cell culture techniques have well-known limitations for aerosol exposure studies; for instance, the impact of exposure dilution within the media and the poor solubility/sedimentation of some exposure particles1. Air liquid interface (ALI) cultures are a technique whereby cells are grown on a microporous membrane insert, immersed in a media-containing well.
Combining implantable telemetry with whole body plethysmography offers a powerful approach that provides researchers with an in-depth understanding of respiratory patterns and mechanisms.
COVID-19 has rapidly spread throughout the world and was declared a pandemic in March of 2020. Currently, there is no clinically validated treatment or vaccine for COVID-19.
Since COVID-19 was declared a global pandemic in March 2020, a massive wave of mobilization has been seen from various companies and organizations at different fronts
State of cannabis research Since the recent legalization of recreational cannabis, there is an increased interest in research into both the pulmonary effects of inhaled cannabis, as well as improving our understanding of the endocannabinoid
Studies demonstrate the ability of Polystyrene microplastics to penetrate deep into the lungs, where they can induce oxidative stress, inflammation and airway remodeling. A recent study by Balkrishna et al. (2025) investigates these effects in a murine model and evaluates Bronchom, a plant-based herbal formulation, as a potential protective intervention.
Idiopathic pulmonary fibrosis (IPF) is a devasting lung disease characterized by progressive scarring of lung tissue. As fibrosis develops, patients experience worsening shortness of breath, reduced lung capacity and ultimately respiratory failure.
Exercise-induced bronchoconstriction (EIB) is a hallmark of asthma and other respiratory diseases. It occurs when vigorous physical activity triggers transient and reversible airway narrowing. Environmental factors such as cold, dry air and air pollution are known to exacerbate symptoms, particularly in athletes and individuals exercising in urban environments.
Cannabis is used by an estimated 192 million people around the world. Most people use cannabis through the inhalation of cannabis smoke, which contains combustion by-products that can negatively affect lung health. . There is currently no standardized in vitro model for assessing the effects of dry cannabis vapor.
While combustible cigarette smoke (CCS) is a well-established carcinogen, the oncogenic potential of electronic cigarette vapor (ECV) remains underexplored. A recent study led by Dr. Moghaddam et al. at The University of Texas MD Anderson Cancer Center provides a rigorous comparative analysis of CCS and ECV exposure in a KRAS-mutant lung adenocarcinoma (KM-LUAD) mouse model.
The Food and Drug Administration’s (FDA) recent Roadmap to Reducing Animal Testing in Preclinical Safety Studies marks a pivotal shift toward the adoption of innovative, human-relevant methodologies commonly known as New Approach Methodologies (NAMs).
Asthma remains a complex and multifactorial disease, with airway hyperresponsiveness to methacholine being a hallmark feature. A recent study by Rojas-Ruiz (2025) utilizes SCIREQ’s innovative physioLens (ex vivo) and flexiVent (in vivo) platforms to shed light on the interplay between lung tissue compliance and methacholine response, offering new insights into the mechanisms driving asthma pathology.
As cannabis use increases, so does the availability of products marketed as safe alternatives to smoking. One of these products is the dry herb vaporizer, which heats the cannabis flower without burning it. This process releases cannabinoids for inhalation. But how safe are these products?
For five years since the onset of the COVID-19 pandemic, the scientific community delved deep into the mysteries of the SARS-CoV-2 virus, to understand its impact on our health and develop antiviral therapies and vaccine.
Obesity is a metabolic condition resulting from an imbalance between the energy consumed and the energy expended. This is often caused by an increase in the intake of calorie-dense foods and a decrease in physical activity, leading to an abnormal build-up of fat. Such fat accumulation can have serious health consequences, raising the risk of chronic diseases like cardiovascular conditions, diabetes, and some cancers. It is usually associated with a higher prevalence of non-alcoholic fatty liver disease (NAFLD) and asthma.
Obesity is a significant contributor to respiratory disorders such as Obesity Hypoventilation Syndrome (OHS) and sleep apnea, both of which are characterized by reduced respiratory chemosensitivity. These conditions not only impair breathing but also exacerbate the health risks associated with obesity.
Yang, L., et al (2024) introduces LungVis 1.0, an AI-driven imaging platform integrating light sheet fluorescence microscopy (LSFM) and deep learning for mapping nanoparticle (NP) deposition across murine lungs. The research highlights the advantages of aerosol-based delivery methods over traditional liquid-based approaches, emphasizing the uniformity of NP deposition in distal alveolar regions achieved via ventilator-assisted aerosol delivery (VAAD).
