The cellular signaling crosstalk between memory B cells and tumor cells in nasopharyngeal carcinoma cannot be overlooked: Their involvement in tumor progression and treatment strategy is significant.

Nasopharyngeal carcinoma (NPC) refers to a cancerous tumor that develops in the upper and side walls of the nasopharyngeal cavity. Typically, individuals are often diagnosed with the disease when it has already progressed significantly, and those with advanced NPC tend to have an unfavorable outlook in terms of response rate to targeted treatments and overall clinical survival. Various molecular mechanisms, including Myeloid-derived suppressor cells and factors like PD-L1, have been explored to enhance the outcome of NPC.

ROS-responsive nanoparticles for bioimaging and treating acute lung injury by releasing dexamethasone and improving alveolar macrophage homeostasis.

Background: Acute lung injury (ALI) triggers the activation of pulmonary macrophages, which in turn produce excessive amounts of reactive oxygen species (ROS).

Results: We synthesized ROS-responsive red light-emitting carbon dots (RCMNs) that target lung macrophages, possess bioimaging capabilities, and efficiently eliminate intracellular ROS, thereby demonstrating anti-inflammatory effects for treating acute lung injury (ALI). In an LPS-induced ALI mouse model, RCMNs showed bioimaging and therapeutic potential, reducing lung damage and inflammation by targeting ROS-damaged tissue.

Adipose transplantation improves metabolism and atherosclerosis but not perivascular adipose tissue abnormality or vascular dysfunction in lipodystrophic null mice.

Adipose dysfunction in lipodystrophic SEIPIN deficiency is associated with multiple metabolic disorders and increased risks of developing cardiovascular diseases, such as atherosclerosis, cardiac hypertrophy, and heart failure. Recently, adipose transplantation has been found to correct adipose dysfunction and metabolic disorders in lipodystrophic knockout mice; however, whether adipose transplantation could improve lipodystrophy-associated cardiovascular consequences is still unclear. Here, we aimed to explore the effects of adipose transplantation on lipodystrophy-associated metabolic cardiovascular diseases in knockout mice crossed into atherosclerosis-prone apolipoprotein E () knockout background.

At present, a large number of studies have demonstrated that miRNAs can be used as biological indicators for the diagnosis and treatment of diseases such as tumours and cancer, so it is important to develop a new miRNA detection platform. In this work, miRNA-122 is used as the basis for targeting detection agents. We have designed an unlabelled DNA1 that undergoes partial hybridisation and has a 20 T base long strand.

Progress in the mechanism of autophagy and traditional Chinese medicine herb involved in alcohol-related liver disease.

Alcohol-related liver disease (ALD) is chronic liver damage caused by long-term heavy drinking with, extremely complicated pathogenesis. The current studies speculated that excessive alcohol and its metabolites are the major causes of liver cell toxicity. Autophagy is evolutionarily conserved in eukaryotes and aggravates alcoholic liver damage, through various mechanisms, such as cellular oxidative stress, inflammation, mitochondrial damage and lipid metabolism disorders.

Leaching kinetic mechanism of iron from the diamond wire saw silicon powder by HCl.

The diamond wire saw silicon powder (DWSSP) is considered to be a harmful to the environment because of finer particles, the large specific surface area and flammability. Removal of Fe impurity is very essential for recovering Si from DWSSP due to the large amount of Fe introduced during the silicon powder generation process. In the study, the thermodynamics of Fe leaching with HCl was analyzed and determined iron was theoretically present as ions in solution.

Recent advances in electrochemical proximity ligation assay.

Proximity ligation assay (PLA) is a vigorously developed homogeneous immunoassay assisted by DNA combining dual recognition of target protein by pairs of proximity probes, in which the detection of protein is tactfully converted to the detection of DNA. The booming developments in PLA have enabled a variety of ultrasensitive assays for the detection of protein and this concept of PLA is also extended to the detection of nucleic acids and some small molecule. The association between PLA and electrochemical method, defined as electrochemical proximity ligation assay (ECPLA), has gained much interests in disease diagnosis, food safety and environmental assays with the advantages, such as broad range of targets, simplicity, low cost and rapid response.

Single-cell sequencing resolves the landscape of immune cells and regulatory mechanisms in HIV-infected immune non-responders.

Immune non-responder after highly active antiretroviral therapy (HAART) is the main cause of opportunistic infections and high mortality in AIDS patients, but the mechanism underlying immune reconstitution failure is poorly understood. Here, we performed scRNA-seq, and scATAC-seq analysis of peripheral blood mononuclear cells (PBMCs) derived from immune non-responder (INR) and responder (IR) HIV-1-infected subjects. We found low expression of mucosal-associated invariant T (MAIT) cells in INRs, which exhibited transcriptional profiles associated with impaired mitochondrial function and apoptosis signaling.
