Summary: The discovery of pyroptosis and its implications in infection and immunity has provided new insights into host defense against pathogens. However, the regulation of pyroptosis is complex and varies between cell types, stimulation conditions, pathogens, and animal species. Excessive inflammation caused by pyroptosis contributes to the development of sepsis. Understanding the regulation of pyroptotic pathways is crucial for identifying potential therapeutic targets for sepsis.

Summary: The study demonstrates that Men1 has conflicting roles in pulmonary fibrosis, as it attenuates fibrosis by inhibiting fibroblast activation and promoting macrophage fibrotic phenotype and migration. The profibrotic role of Men1 in macrophages may be mediated by regulating macrophage pyroptosis and OPN expression.

Summary: GSDMD and GSDME, members of the gasdermin protein family, are involved in the formation of plasma membrane channels contributing to cell rupture during a certain type of necrosis called pyroptosis. This study found that the expression of the GSDMD gene increases significantly during LPS-induced pyroptosis, while GSDME expression decreases. Additionally, glucose availability was found to be important for the increasing effect of LPS on GSDMD expression.

Summary: The study shows that oxidized phospholipids can induce pyroptosis via noncanonical inflammasome activation, promoting the development of atherosclerosis. Further experiments demonstrate that inflammatory signaling mediated by caspase-11 and gasdermin D is significantly activated in peripheral blood mononuclear cells from patients with coronary heart disease.

Summary: The necroptotic signaling pathway of macrophages is significantly activated in the lungs of silicosis mouse models, promoting the progression of silicosis through enhancing lung inflammatory responses and fibrogenesis. Increased M1 macrophage infiltration and up-regulation of pro-inflammatory cytokines were observed in this study, along with the up-regulation of pro-fibrotic factors and fibrosis biomarkers, which were recovered by the specific inhibitor of RIP1 kinase-dependent necroptosis. These findings provide new insights for the treatment of silicosis.

Summary: Stroke, a major cause of death and disability, leads to neuroinflammation which can be targeted for therapeutic interventions. Pyroptosis, a form of programmed cell death, involves GSDMD as a key player in triggering inflammatory responses and cell death in ischemic stroke. Understanding the role of GSDMD may provide new insights for novel therapeutic strategies.

Summary: Elevated levels of cytokines IL-1(3 and IL-6 are associated with severe COVID-19. Investigating the underlying mechanisms, it was found that primary human airway epithelia (HAE) are not the source of IL-1(3 released upon SARS-CoV-2 infection. The SARS-CoV-2 E protein upregulates inflammasome gene transcription via TLR2 in leukocytes, while infected HAE supply a second signal, including genomic and mitochondrial DNA, to stimulate leukocyte IL-1(3 release.

Summary: This study revealed the upregulation of IRF4 in fibrotic lung tissues of mice exposed to silica particles and verified the increased expression of IRF4 in SiO2-treated macrophages and TGF-beta 1-treated fibroblasts. The down-regulation of IRF4 impeded macrophage polarization and the release of pro-fibrotic factors, as well as alleviated migration, invasion, and the expression of fibrotic molecules in fibroblasts. IRF4 was found to regulate the transcriptional activity of the IL-17A promoter, stimulating fibroblast activation, migration, and invasion. In vivo experiments showed that IRF4 knockdown alleviated the fibrotic responses in mouse lung tissues.

Summary: The effects of integrated stress response inhibitor (ISRIB) on cellular senescence and pulmonary fibrosis in silicosis were evaluated. ISRIB significantly reduced the degree of pulmonary fibrosis and reversed the expression of senescence-related factors in mice with silicosis. These findings suggest that ISRIB may alleviate pulmonary fibrosis in silicosis by inhibiting cellular senescence.

Summary: This study established silicosis mouse models to investigate the effectiveness of tetrandrine in early and late therapeutic administration, revealing its novel mechanism of attenuating silicosis by inhibiting the NLRP3 inflammasome pathways in lung macrophages. The findings not only demonstrated promising results against silicosis-associated inflammation and fibrosis, but also laid the groundwork for understanding the molecular targets of tetrandrine, potentially leading to a globally accepted therapeutic strategy for silicosis.

Summary: Surface albedo plays a crucial role in the energy and water cycles, and the parameterizations of surface albedo greatly impact the simulation of radiation partition in climate models. In this study, in-situ measurements and MODIS albedo product were used to evaluate the simulated surface albedo by 24 Global Climate Models. The results showed varying monthly albedo among models, with the ensemble mean closer to in-situ measurements. Some models exhibited significant biases in annual surface albedo cycle, and snow albedo parameterization schemes varied in fitting snow albedo attenuation over time in all models.

Summary: Under the intensification of global warming, the characteristics of the Three Rivers source region in China were diagnosed using observations and reanalysis data. The study found significant interdecadal variability in summer precipitation in this region, with a noticeable increase after 2002, which was strongly associated with the interdecadal position and intensity of the East Asian westerly jet. The study also revealed a negative correlation between the position index of the East Asian westerly jet and precipitation in the Three Rivers source region.

Summary: This study evaluated the impacts of regional climate and vegetation change on runoff in the Three Rivers Source Region (TRSR). The results showed that precipitation was the dominant factor affecting runoff and evapotranspiration (ET), while temperature had a relatively small contribution to runoff. Vegetation change had a significant impact on runoff, and the Dynamic Global Vegetation Model (DGVM) effectively simulated the changes in vegetation and runoff.

Summary: Extreme snowfall events have been increasing in the Tibetan Plateau and have caused greater variations in snow cover conditions. This study analyzed the impacts of snow cover on water-heat transfer in alpine meadows using five years of observation data. The findings indicate that snow cover decreases soil temperature and inhibits extremely low temperatures in the soil. Different snow conditions also affect soil thawing, snowmelt infiltration, and surface soil water evaporation. The study provides insights into soil water-heat transfer under extreme snow cover conditions in the Tibetan Plateau.

Summary: Evapotranspiration plays a crucial role in maintaining the ecological stability of oases and is influenced by irrigation and urbanization expansion. By analyzing the spatial and temporal characteristics of evapotranspiration in Zhangye Oasis, Jinta Oasis, and Ejina Oasis, it is found that there are differences in evapotranspiration intensity among different oases, and urbanization expansion leads to a decrease in evapotranspiration intensity in oases.

Summary: This paper investigates the local and non-local climatic effects of wetter arid areas of Northwestern China (ANWC) in summer using a fully coupled climate model. The results show that with increasing soil moisture, the local air temperature decreases significantly and precipitation increases during summer. The wetter ANWC leads to a warmer and rainless climate over the Central part of North China Plain (CNCP), while its influence on Tibetan Plateau (TP) precipitation is negligible due to the high altitude.

Summary: The seasonal ice cover in lakes of the Qinghai-Tibet Plateau is a vulnerable part of the cryosphere that is influenced by regional climate. This study focuses on the mechanism of solar thermal accumulation under ice using temperature observations from Ngoring Lake and a lake model. The results show that solar radiation is the main source of under-ice warming, and the accumulated heat has a delayed effect on land-atmosphere heat exchange.
