Mechanical forces can be recognized by mechanical signal receptors on the cell surface, such as cell adhesion molecules and ion channels, and transformed into intracellular biological signals, in turn activating different signaling pathways and thereby regulating the phagocytosis, migration, and polarization of macrophages. The phenomenon in which macrophages transform into different activated phenotypes and perform different functions under varying environmental stimuli is also known as macrophage polarization. In this review, we discuss the roles of mechanically sensitive integrins and ion channels in the mechanical signal sensing of macrophages. We expound on several downstream signaling pathways closely related to integrins and ion channels, such as the nuclear factor-κB (NF-κB), mitogen-activated protein kinase (MAPK), and Yes-associated protein (YAP)/transcriptional co-activator with PDZ-binding motif (TAZ) pathways, which have made good research progress. In addition, we summarize some in vitro experiments on the regulation of macrophage polarization by external mechanical forces, some current cell models for macrophages in vitro, and some commonly used force application devices, with the aim to provide convenience for future in vitro research on macrophages. This paper offers a deep understanding of the mechanical sensitivity and conduction mechanisms of macrophages, which can provide new ideas for the treatment of human diseases.</p>","PeriodicalId":17797,"journal":{"name":"Journal of Zhejiang University SCIENCE B","volume":"27 2","pages":"129-148"},"PeriodicalIF":5.7,"publicationDate":"2025-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12885616/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146142679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Succinate, primarily known as a metabolic intermediate in the tricarboxylic acid (TCA) cycle, has emerged as a regulator of cellular functions beyond its metabolic role. Under stress, succinate accumulates in mitochondria and acts as a signaling molecule, modulating cellular processes. Notably, succinate activates angiogenesis and inflammation by stabilizing hypoxia-inducible factor-1α (HIF-1α). Moreover, it influences various pathophysiological processes by interacting with the succinate receptor 1 (SUCNR1), thereby impacting immune response, inflammation, cancer metastasis, and bone homeostasis. The multifaceted roles of succinate as a signaling molecule vary depending on its cellular location and concentration. Recent metabolomic analyses have revealed elevated succinate levels in bone-related diseases, indicating its potential association with these conditions.

The substrate, acting both as a physical support and a nutrient reservoir, is critical for orchid development. Therefore, the careful selection of an appropriate growth substrate is of paramount importance. However, existing research on the relationship between orchid growth and substrate properties relies mainly on manual measurements of physiological indicators, with limited application of high-throughput phenotyping (HTP) platforms. In this study, we evaluated three distinct substrate types, peat soil mixed with perlite, pine bark, and river sand, which were applied to two orchid species, <i>Cymbidium goeringii</i> and <i>Cymbidium faberi</i>. Using the high-throughput Plantarray lysimetric system, we continuously recorded environmental parameters (photosynthetically active radiation, humidity, and temperature) as well as key growth metrics (biomass accumulation, canopy conductance, and transpiration rate). This platform enabled precise and rapid quantification of orchid growth indicators. The results show that the type of substrate significantly affects orchid growth. Under controlled conditions, mixed substrates that provide balanced nutrition and excellent drainage enhanced orchid growth compared to other substrates. Additionally, when the data obtained from the HTP platform were compared with those from traditional manual measurements, the automated system showed higher reliability and accuracy.

Bacteria performing simultaneous nitrification and denitrification (SND) can be effective biological instruments to remove ammonia nitrogen completely from effluents. For the first time, <i>Pseudomonas oleovorans</i> QS-7 with SND function, isolated from the biogas treatment system of a pig farm, was found to efficiently remove ammonia nitrogen. Through the determination of key enzymes and functional genes related to the nitrogen metabolism of strain QS-7, combined with nitrogen balance measurements of the nitrogen metabolic process, it was speculated that the SND pathway of the novel strain is N H 4+ →NH<sub>2</sub>OH→ N O 2- → N O 3- → N O 2- →NO→N<sub>2</sub>O→N<sub>2</sub>. QS-7 exhibited 98.6% ammonia nitrogen removal and a maximum ammonia degradation rate of 9.2 mg/(L·h) at 18 h in 100 mg/L ammonia nitrogen solution. This strain also has a certain capacity to remove nitrate and nitrite nitrogen; the maximum removal efficiencies were 54.22% and 73.93%, respectively, in systems with 100 mg/L of nitrate or nitrite nitrogen as the sole nitrogen source. Nitrogen metabolic balance analysis for QS-7, using ammonia (100 mg/L) as the sole nitrogen source, demonstrated that assimilation (56.1%) is the main mode of nitrogen removal, followed by conversion to N<sub>2</sub> (43.6%). Meanwhile, N O 2- was not detected, and almost no NO<i><sub>x</sub></i> was produced, which indicates that the nitrogen removal process of QS-7 is environmentally friendly. The optimal environmental conditions for QS-7 were found to be sodium citrate as the carbon source, C/N=10, pH=7.0, 150 r/min, and 30 ℃.
