Summary: Multiple studies have shown that P2X purinergic receptors play a crucial role in inflammation. These receptors, when activated, release inflammatory cytokines and contribute to the progression of inflammatory diseases. In an inflammatory microenvironment, cells release ATP to activate P2X receptors, leading to the activation of various intracellular signaling pathways and the release of multiple inflammatory cytokines, thereby amplifying the inflammatory response. P2X4 and P2X7 receptors are especially important in the process of inflammation, mediating the activation of microglia and different inflammatory cells, respectively, and contributing to tissue-wide inflammation. This paper discusses the role of P2X receptors in mediating inflammation and describes the effects of various antagonists on inflammation relief by targeting P2X receptors.

Summary: Aloe-emodin, a novel androgen receptor (AR) antagonist, has been identified to inhibit AR signaling by promoting apoptosis, modulating AR protein levels, inhibiting AR downstream target genes, and preventing the nuclear translocation of AR. These findings suggest that aloe-emodin may play a crucial role in prostate cancer prevention and treatment.

Summary: Historically, renal vascular and tubular function has been mainly controlled through neural and endocrine regulation. However, it is now acknowledged that complex humoral control systems exist within the kidney, complementing neuroendocrine regulation by fine-tuning renal function in response to rapid changes. The extracellular nucleotide/P2 receptor system plays a central role in intrinsic regulatory feedback loops within the kidney, contributing to the understanding and potential treatment of kidney disease.

Summary: By using a microfluidic chip-based technique, we have developed a method for studying ion currents and fluorescence signals in order to measure the kinetics of channel activation and deactivation, as well as ligand binding and unbinding. This approach allows for the rapid generation of concentration-activation relationships and activation kinetics, while minimizing the effects of interference.

Summary: The P2X7 receptor is a calcium-permeable cation channel activated by high concentrations of extracellular ATP, playing crucial roles in physiological and pathological processes. Investigation of the role of tyrosine at position 288 in the extracellular domain contributes to a deeper understanding of the structure-function relationships of the hP2X7R.

Summary: Epigenetic reprogramming and silk scaffolds were used to promote bone formation of human dental pulp stromal cells (hDPSCs). The study demonstrated that MI192 pre-treatment significantly enhanced hDPSCs alkaline phosphatase activity and promoted bone extracellular matrix deposition and mineralisation. The hDPSCs-silk scaffold constructs also enhanced vascularisation and extracellular matrix mineralisation in vivo.

Summary: The P2X4 purinergic receptor is upregulated in breast cancer patients and primarily localised in endolysosomes. It promotes breast cancer invasion, tumour growth, and metastasis by regulating lysosome acidity, promoting autophagy and cell survival. It is also associated with epithelial-to-mesenchymal transition and plays a more significant role under metabolic challenges.

Summary: The cooperation between IKCa and TRPC1 channels in mediating calcium influx and activating the ERK1/2 pathway is critical for vascular smooth muscle cell (VSMC) proliferation. Inhibition or knockdown of IKCa or TRPC1 suppresses serum-induced cell proliferation and increases in intracellular calcium concentration. Additionally, extracellular calcium removal or TRPC1 knockdown significantly inhibits VSMC proliferation. These findings provide new insights into the mechanisms underlying VSMC proliferation.

Summary: Microglial cell function and inflammation are regulated by the activation of Piezo1 channel. This study found that the activation of Piezo1 channel can inhibit the pro-inflammatory activation and production of pro-inflammatory cytokines in microglial cells by initiating intracellular Ca2+ signaling to inhibit the NF-kappa B inflammatory signaling pathway.

Summary: Stroke prognosis is negatively affected by elevated levels of serum bilirubin, but the mechanism of how bilirubin worsens outcomes is still unknown. This study found that post-stroke bilirubin levels, but not pre-stroke levels, are associated with infarct volume in hospitalized patients. Mouse models showed that bilirubin increases neuronal excitability and ischemic infarct size, and ischemic insults trigger the release of endogenous bilirubin, which activates TRPM2 channels. Knockout or antagonization of the TRPM2 channel attenuates these effects. These findings suggest a vicious cycle of stroke injury involving the release of endogenous bilirubin and activation of TRPM2 channels, exacerbating Ca2+-dependent brain injury.

Summary: In this study, it was found that the TRPM2 channel plays a crucial role in the development and progression of HCC. Inhibition or silencing of TRPM2, as well as inhibition of the downstream signaling pathway, significantly suppressed the proliferation of HCC cells. Furthermore, inhibition or depletion of TRPM2 also slowed down the growth of HCC xenografts in mice, indicating its potential as a therapeutic target for HCC.

Summary: Tau protein hyperphosphorylation and NFTs formation are key features of AD, and DpdtpA can attenuate these processes by regulating the PI3K/AKT/GSK-36 signaling pathway. DpdtpA also reduces microglial activation and inflammatory responses induced by Tau, offering a potential treatment option for AD-associated neuroinflammation.

Summary: This study found that TRPM2 deficiency could alleviate liver dysfunction, inflammation, and cell death caused by hepatic ischemia-reperfusion (IR) injury. Further research indicated that TRPM2 mediates hepatic IR injury through ferroptosis-related pathways. Animal experiments and in vitro studies showed that inhibition of TRPM2 and calcium depletion could significantly attenuate IR-induced ferroptosis. These findings reveal the crucial role of TRPM2-mediated ferroptosis in hepatic IR injury and suggest that pharmacological inhibition of TRPM2 may be an effective therapeutic strategy for hepatic IR injury-related diseases, such as during liver resection and transplantation.
