With imaging-based spatial transcriptomics, we analyzed the gene expression patterns in 17 human infant lungs at varying stages of development and injury, creating a spatial transcriptomic atlas of approximately 1.2 million cells. We applied computational clustering approaches to identify shared molecular patterns among this cohort, informing how tissue architecture and molecular spatial relationships are coordinated during development and disrupted in disease. Recognizing that all preterm birth represents an injury to the developing lung, we created a simplified classification scheme that relies upon the routinely collected objective measures of gestational age and lifespan. Within this framework, we have identified cell type patterns across gestational age and life span variables that would likely be overlooked when using the conventional \"disease versus control\" binary comparison.

We used a CB₁R inverse agonist, INV-202, in a mouse model of obese asthma and investigated changes in weight, inflammation, airway reactivity, and surfactant lipids. Mice were fed low or high-fat diets (LFD, HFD), and house dust mite (HDM) extract was delivered intranasally to induce allergic airway inflammation. Mice received INV-202 by oral gavage. Airway hyperresponsiveness was measured by FlexiVent, and lung tissue cytokines were measured by ELISA. Leukocytes and lipids in the bronchoalveolar lavage fluid (BALF) were analyzed by flow cytometry and mass spectroscopy, respectively.

Phosphatidylglycerol in BALF increased with INV-202, which significantly correlated with compliance in LFD mice.

We hypothesize that DI prohibition allows basal airway smooth muscle (ASM) tone to narrow and close airways over time, resulting in elevation of airway and lung resistance, as well as air trapping. We further hypothesize that DI or pharmacological bronchodilators can prevent or alleviate the resistance increase and air trapping. Physiological respiration was simulated in ex vivo sheep lungs. Lung resistance, elastance, and volume were measured using small tidal volume (120 mL), ventilation frequencies of 0.25 and 2 Hz, and transpulmonary pressure of 7.5 cmH₂O in the presence and absence of DI and bronchodilators. A DI maneuver, involving rapid inflation to total lung capacity followed by deflation to zero transpulmonary pressure, was used to resolve air trapping. Lung resistance and elastance were recorded pre- and post-DI. The experiments were also conducted in the presence of the bronchodilator salbutamol to assess the role of ASM. Ventilation without DI increased lung resistance and elastance, as well as air trapping. DI effectively resolved air trapping, restoring resistance and elastance to their initial values. Salbutamol also alleviated the increase in lung resistance, elastance, and air trapping. DI prevented air trapping and reduced lung resistance and elastance in ex vivo sheep lungs during tidal ventilation, playing a similar role as a pharmacological bronchodilator.<b>NEW & NOTEWORTHY</b> We showed that air trapping is a consistent feature in ex vivo sheep lungs possessing spontaneous bronchoconstriction, when the lungs are ventilated with small tidal volume without intermittent deep inspirations.

This study aimed to investigate the underlying molecular mechanism from the perspective of metabolites. Pregnant C57BL/6 mice received an intraperitoneal injection of LPS on <i>gestational day 12.5</i> to establish an intrauterine inflammation model. The results showed that prenatal LPS exposure induced bronchopulmonary dysplasia (BPD)-like alveolar simplification. Then, by LC/MS untargeted metabolomics analysis, succinic acid was found to be elevated in murine placentas and preterm human umbilical cord blood with intrauterine inflammation. Besides, the expression of succinate dehydrogenase B subunit (Sdhb), a key catalytic enzyme of succinic acid, was downregulated in the murine placentas with intrauterine inflammation. Tail intravenous administration of <i>Sdhb</i> siRNA led to the accumulation of succinic acid in the placenta and aggravated LPS-induced lung injury in the offspring. In offspring mice, intrauterine inflammation decreased E-cadherin levels in lung tissue, which were further reduced by <i>Sdhb</i> siRNA injection.
