Summary: This study investigated the effects of ischemia-reperfusion and ex vivo lung perfusion (EVLP) on gene expression in human pulmonary microvascular endothelial cells and epithelial cells. The results showed that both cell types exhibited changes in gene expressions after ischemia-reperfusion or EVLP, with the former showing upregulated pro-inflammatory genes and downregulated cell metabolism pathways, while the latter showed downregulation of cell metabolism without any inflammatory signals.

Summary: This study found that the occurrence of sterile lung inflammation during lung transplantation is significantly dependent on the conditions, and EVLP may promote inflammation, while factors such as HMGB1 and S100A8 may play important roles in the pathogenesis of LTx.

Summary: Ex vivo lung perfusion (EVLP) serves as a platform for pharmacologic repair before lung transplantation (LTx). This study demonstrates that transient heat application during EVLP can effectively recondition damaged lungs and improve their outcomes after transplantation.

Summary: Recent advances in tagging and biologging technology have provided unprecedented insights into wild animal physiology, but analyzing time-series data from wild tracking studies presents numerous challenges, requiring careful application of existing statistical tools to obtain robust quantitative estimates. Researchers can optimize information yield by avoiding pitfalls, optimizing study design, and addressing inherent limitations through a combination of simulated and real datasets.

Summary: Sheep lungs acquired from an abattoir can be perfused ex vivo under similar conditions as lab animal lungs, with similar results in terms of oxygenation and ATP restoration. Furthermore, costs can be significantly reduced by using this abattoir model. By increasing accessibility and lowering costs for lung perfusion experiments, more results can be achieved in the field of lung diseases.

Summary: The immune response is crucial in determining disease severity in COVID-19. Research has found that in the early stages of infection, monocyte-derived macrophages in the lungs exhibit the earliest and strongest transcriptional response to infection.

Summary: The study suggests that EVLP of diseased human lungs is suitable for translational research on chronic lung diseases. By perfusing the lungs for 6 hours with EVLP, researchers were able to assess airway mechanics, pulmonary hemodynamics, gas exchange, and biochemical parameters continuously. Tissue biopsies were also collected to isolate RNA and DNA for identifying unique gene expressions of different diseases, demonstrating the utility of EVLP as a relevant experimental model for understanding pulmonary pathophysiology and various human lung diseases.

Summary: This mini review discusses the current status, advantages, and disadvantages of large animal modeling of breast cancer (BC). Recently, there has been interest in developing porcine BC models, which show promising results for mimicking human disease. The widely used rodent models of BC are also briefly reviewed. The availability of large animal BC models could provide additional tools for BC research and models with greater biological relevance.

Summary: Summary: Out of 222 Nobel Prize of Physiology or Medicine (NPPM) awarded projects, 144 used mammalian models, with rodents being the most commonly used group of species. Additionally, 92 researchers included domestic species in their work. The criteria for choosing species, number of animals used, and experimental protocol are debatable and dependent on the scientific area, but the 3R's principle applies to most fields. Despite the species, animal models can be classified based on ecology, genetics, and mode of action.

Summary: A study found that freezing and injecting allogeneic mitochondria into damaged lung tissue can reduce graft rejection caused by ischemia-reperfusion injury during lung transplantation. The transplanted mitochondria induce autophagy and improve lung function through anti-inflammatory and antioxidant effects. The results provide new insights into the therapeutic potential of mitochondrial transplant to alleviate ischemia-reperfusion injury during lung transplant.

Summary: This study characterized the progression of muscle and fat changes over time after the repair of a chronic rotator cuff tear in a rabbit model. The results showed that atrophy and muscle degeneration peaked around 2 weeks after repair, with no significant regeneration observed. Fat accumulation and fibrosis were increased at all time points compared to the contralateral side.

Summary: This study developed a novel adjuvant candidate by combining liposome and QS-21 adjuvant, which can induce strong Th1 or Th17 cellular immunity and provide protection against pertussis. Results showed that the liposome + QS-21 adjuvant group had a rapid and higher antibody response, induced neutralizing antibodies, and recruited more IL-17A-secreting T-RM cells in mice, thus providing a key basis for developing an acellular pertussis vaccine.
