Infiltrating plasma cells maintain glioblastoma stem cells through IgG-Tumor binding.

Glioblastoma is a highly aggressive primary brain tumor with glioblastoma stem cells (GSCs) enforcing the intra-tumoral hierarchy. Plasma cells (PCs) are critical effectors of the B-lineage immune system, but their roles in glioblastoma remain largely unexplored. Here, we leverage single-cell RNA and B cell receptor sequencing of tumor-infiltrating B-lineage cells and reveal that PCs are aberrantly enriched in the glioblastoma-infiltrating B-lineage population, experience low level of somatic hypermutation, and are associated with poor prognosis.

ECSIT-X4 is Required for Preventing Pressure Overload-Induced Cardiac Hypertrophy via Regulating Mitochondrial STAT3.

Mitochondrial dysfunction is a key factor in exacerbating pressure overload-induced cardiac hypertrophy and is linked to increased morbidity and mortality. ECSIT, a crucial adaptor for inflammation and mitochondrial function, has been reported to express multiple transcripts in various species and tissues, leading to distinct protein isoforms with diverse subcellular localizations and functions. However, whether an unknown ECSIT isoform exists in cardiac cells and its potential role in regulating mitochondrial function and pathological cardiac hypertrophy has remained unclear.

SIGIRR plays a dual role in zebrafish infected with Edwardsiella piscicida: Boosting digestive system wellness and mitigating inflammation.

Single immunoglobulin interleukin-1 receptor-associated protein (SIGIRR) negatively regulates the inflammatory response induced by bacterial infection by inhibiting the excessive synthesis of inflammatory mediators and overactivation. This inhibitory mechanism reduces the fish's susceptibility to pathogens and enhances survival rates. Zebrafish lacking the SIGIRR gene were generated using CRISPR/Cas9 gene knockout technology.

Experimental Study on the Effects of Washing Time, Washing Temperature, and Particle Size on the Combustion and Ash Formation Characteristics of Rice Husk.

There are many problems in the direct combustion of biomass, such as low combustion efficiency and easy slagging.

Establishing age-group specific reference intervals of human salivary proteome and its preliminary application for epilepsy diagnosis.

Salivary proteins serve multifaceted roles in maintaining oral health and hold significant potential for diagnosing and monitoring diseases due to the non-invasive nature of saliva sampling. However, the clinical utility of current saliva biomarker studies is limited by the lack of reference intervals (RIs) to correctly interpret the testing result. Here, we developed a rapid and robust saliva proteome profiling workflow, obtaining coverage of >1,200 proteins from a 50-µL unstimulated salivary flow with 30 min gradients.
