Parenchymal and Inflammatory Responses to Ozone Exposure in the Aging Healthy and Surfactant Protein C Mutant Lung.

Ozone (O) is a ubiquitous pollutant known to produce acute, transient inflammation through oxidative injury and inflammation. These effects are exacerbated in susceptible populations, such as the elderly and those exhibiting genetic mutations in central nodes of pulmonary function. To comprehend the impact of these predisposing factors, the present study examines structural, mechanical, and immunological responses to single acute O exposure (0.

Pro-inflammatory effects of inhaled Great Salt Lake dust particles.

Background: Climate change and human activities have caused the drying of marine environments around the world. An example is the Great Salt Lake in Utah, USA which is at a near record low water level. Adverse health effects have been associated with exposure to windblown dust originating from dried lakebed sediments, but mechanistic studies evaluating the health effects of these dusts are limited.

Application of deep learning models on single-cell RNA sequencing analysis uncovers novel markers of double negative T cells.

Double negative T (DNT) cells are a unique subset of CD3 + TCRαβ + T lymphocytes that lack CD4, CD8, or NK1.1 expression and constitute 3-5% of the total T cell population in C57BL/6 mice. They have increasingly gained recognition for their novel roles in the immune system, especially under autoimmune conditions.
