Summary: Vascular aging is characterized by the fragmentation of elastic fibers and collagen deposition, leading to reduced distensibility and increased stiffness in the blood vessels. Research shows that aging promotes changes in smooth muscle cell phenotypes, ultimately resulting in mechanical impairment of aging arteries. Understanding the role of ECM changes during aging may help in developing new strategies to prevent or delay arterial aging and cardiovascular diseases.

Summary: The study suggests that inducible deletion of PHD2 in endothelial cells can lead to progressive lung disease, while deletion in arterial smooth muscle cells results in elevated right ventricular pressure without alterations in vascular tone regulators. Mechanistically, PHD2 inhibition in smooth muscle cells involves actin polymerization-related tension development via activated cofilin.

Summary: A study using single-cell RNA sequencing on mouse AAA tissues revealed 12 distinct populations of 8 cell types. The percentages of each population and gene expression were compared between sham and AAA tissue, showing that populations within major cell types such as smooth muscle cells, fibroblasts, and macrophages may contribute differently to AAA pathogenesis.

Summary: In this study, the involvement of RGC-32 in cell proliferation and cell cycle activation in endothelial cells and smooth muscle cells in atherosclerosis was investigated. Overexpression of RGC-32 enhanced the cell cycle activation and proliferation induced by C5b-9, while silencing of RGC-32 inhibited this activation.

Summary: The pathophysiology of high-altitude pulmonary edema is thought to be the result of exacerbated hypoxic pulmonary vasoconstriction. In this review, the authors focus on the cellular mechanisms in the pulmonary acinus that respond to hypoxia, leading to the accumulation of fluid in the alveoli. These mechanisms include damage to the fluid reabsorption capacity of alveolar epithelial cells, increased permeability of endothelial and epithelial cells, activation of inflammation by alveolar macrophages, disruption of extracellular matrix architecture and tight junctions, and induced pulmonary vasoconstriction. The complex intercellular network of the alveolar-capillary barrier is affected by acute hypoxia in all its components, resulting in rapid water accumulation in the alveoli.

Summary: This study reveals that aortic cells adapt to stress by modifying their functions, leading to a protective adaptive response against aortic aneurysm and dissection (AAD). The adaptive response involves upregulation of genes related to wound healing, elastin and collagen production, proliferation, migration, cytoskeleton organization, cell-matrix focal adhesion, and PI3K-PKB/Akt and TGF-beta signaling. YAP is identified as an important transcription complex driving the expression of these genes and plays a role in mechanical signal transduction.

Summary: A new coculture model was developed in this study to investigate cellular interactions under higher wall shear stress (WSS) conditions. The model showed similar characteristics to healthy blood vessels under high WSS conditions and exhibited different expression ratios of matrix metalloproteinases and their inhibitors.

Summary: The study found that the ECM deposited by asthmatic and non-asthmatic ASM cells under non-stimulated conditions had similar composition and angiogenic potential, both capable of regulating the behavior of endothelial cells. This suggests that the dysregulation of airway ECM in asthma is driven by even low levels of inflammation, emphasizing the need for more effective anti-inflammatory therapies to maintain airway ECM and regulate aberrant angiogenesis.

Summary: There is little doubt that final victories over pandemics, such as COVID-19, are attributed to herd immunity, either through post-disease convalescence or active immunization of a high percentage of the world's population with vaccines, which demonstrate protection from infection and transmission and are available in large quantities at reasonable prices. However, it is assumable that humans with immune defects or immune suppression, e.g., as a consequence of allograft transplantation, cannot be immunized actively nor produce sufficient immune responses to prevent SARS-CoV-2 infections. These subjects desperately need other strategies, such as sophisticated protection measures and passive immunization.

Summary: Proteomics is an essential analytical technique for studying biological systems using different proteins. The study compared the qualitative and quantitative performance of two commonly used proteomics techniques, label-free shotgun and 2D-DIGE, using six technical and three biological replicates of the human prostate carcinoma cell line DU145. The results showed that label-free shotgun quickly provides an annotated proteome but with reduced robustness compared to 2D-DIGE, which offers qualitative and quantitative information on proteoforms and post-translational modifications. However, the 2D-DIGE technique requires more time and manual work. Ultimately, this work highlights the different outputs and applications of these two techniques for biological research.
