The brain's primary immune cells, microglia, are a leading causal cell type in Alzheimer's disease (AD). Yet, the mechanisms by which microglia can drive neurodegeneration remain unresolved. Here, we discover that a conserved stress signaling pathway, the integrated stress response (ISR), characterizes a microglia subset with neurodegenerative outcomes.

Recent advancements in flexible bioelectronics have enabled continuous, long-term stable interrogation and intervention of biological systems. However, effectively utilizing the interrogated data to modulate biological systems to achieve specific biomedical and biological goals remains a challenge. In this study, we introduce an AI-driven bioelectronics system that integrates tissue-like, flexible bioelectronics with cyber learning algorithms to create a long-term, real-time bidirectional b ioelectronic interface with o ptimized a daptive intelligent m odulation (BIO-AIM).

The development of in vitro hepatocyte cell culture systems is crucial for investigating drug-induced liver injury (DILI). One prerequisite for monitoring DILI related immunologic reactions is the extension of primary human hepatocyte (PHH) cultures towards the inclusion of macrophages. Therefore, we developed and characterized an autologous co-culture system of PHH and primary human hepatic macrophages (hepM) (CoC1).

Phosphorylated small molecule metabolites play crucial roles in physiological processes such as glycogen metabolism and inflammation regulation. However, their high polarity, structural similarity, poor chromatographic separation, and weak mass spectrometric signals make their accurate quantification challenging, thereby hindering the study of related metabolic mechanisms and diseases. To address these challenges, we developed a novel derivatization reagent, DMQX (5-diazomethane quinoxaline), and combined it with liquid chromatography-mass spectrometry (LC-MS).

Dermal hyperpigmentation stands out among the various skin pigmentation phenotypes in chickens, where most other pigmentation variants affect feather color and patterning predominantly. Despite numerous black chicken breeds worldwide, only a select few exhibit comprehensive black pigmentation, which encompasses the skin, meat, flesh, and bones. The process of skin melanin pigmentation is intricate and develops successively.

Targeted therapy has emerged as a transformative breakthrough in modern medicine. Oligonucleotide drugs, such as antisense oligonucleotides (ASOs) and small interfering RNAs (siRNAs), have made significant advancements in targeted therapy. Other oligonucleotide-based therapeutics like clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR-associated protein (Cas) systems are also leading a revolution in targeted gene therapy.

During viral infections, autophagy functions as a cell-intrinsic defense mechanism by facilitating the delivery of virions or viral components to the endosomal/lysosomal pathway for degradation. In this study, we report that internalized African swine fever virus (ASFV) virions enter autolysosomes during the early phase of viral infection. Autophagy selectively targets the major capsid protein p72 within the ASFV virion.

Transglutaminase (TGase)-mediated cross-linking has gained significant attention due to its potential to reduce the allergenicity of food proteins. This study investigates the effects of TGase cross-linking on allergenicity and conformational modifications in a dual-protein system comprising soy protein isolate (SPI) and β-lactoglobulin (β-LG). The results showed that TGase cross-linking effectively decreased the allergenic potential of both SPI and β-LG, with a more pronounced reduction observed in the allergenicity of soy protein in the dual-protein system.

Understanding the molecular targets of natural products is crucial for elucidating their mechanisms of action, mitigating toxicity, and uncovering potential therapeutic pathways. Icaritin (ICT), a bioactive flavonoid, demonstrates significant anti-tumor activity but lacks defined molecular targets. This study employs an advanced strategy integrating proteolysis targeting chimera (PROTAC) technology with quantitative proteomics to identify ICT's key targets.

Background: Precancerous lesions of gastric cancer (PLGC) represent critical stages in gastric cancer progression, with a high risk of malignancy. Current treatments, such as Helicobacter pylori eradication, show limited efficacy in reversing precancerous molecular changes. Zuojin Pill (ZJP), a traditional Chinese medicine, has demonstrated potential for treating digestive disorders and may offer a promising approach for PLGC intervention.

Due to the differences and variances in genetic background, in vitro and animal models cannot meet the modern medical exploration of real human brain structure and function. Recently, brain organoids generated by human pluripotent stem cells (hPSCs) can mimic the structure and physiological function of human brain, being widely used in medical research. Brain organoids generated from normal hPSCs or patient-derived induced pluripotent stem cells offer a more promising approach for the study of diverse human brain diseases.

Triterpenoids are natural products found in plants that exhibit industrial and agricultural importance. Triterpenoids are typically synthesized through two main pathways: the mevalonate (MVA) and methylerythritol 4-phosphate (MEP) pathways. They then undergo structural diversification with the help of squalene cyclases (OSCs), cytochrome P450 monooxygenases (P450s), UDP glycosyltransferases (UGTs), and acyltransferases (ATs).

In recent years, great progress has been made in haploidentical hematopoietic stem cell transplantation (haplo-HSCT) treatment for hematological malignant diseases because of the advent of novel conditioning regimens, optimized graft manipulation, improved graft-versus-host disease (GVHD) prophylaxis, and advances in supportive care. Recent studies have shown very favorable outcomes in severe aplastic anemia (SAA) patients, with comparable outcomes to those of patients receiving immune suppressive therapy (IST) and allogeneic HSCT from a matched sibling donor (MSD) or matched unrelated donor (MUD). However, most of the previous studies relied on single-center data analyses, and the conditioning regimen, GVHD prophylaxis and supportive care used were relatively singular.
