Acute inflammation induces acute megakaryopoiesis with impaired platelet production during fetal hematopoiesis.

Development

January 2025

Institute for Regenerative Medicine, State Key Laboratory of Cardiology and Medical Innovation Center, Shanghai East Hospital, School of Life Sciences and Technology, Tongji University, Shanghai 200092, China.

Hematopoietic development is tightly regulated by various factors. The role of RNA m6A modification during fetal hematopoiesis, particularly in megakaryopoiesis, remains unclear. Here, we demonstrate that loss of m6A methyltransferase METTL3 induces formation of double-stranded RNAs (dsRNAs) and activates acute inflammation during fetal hematopoiesis.

Discovery of a heparan sulfate binding domain in monkeypox virus H3 as an anti-poxviral drug target combining AI and MD simulations.

Elife

January 2025

State Key Laboratory of Coordination Chemistry, Chemistry and Biomedicine Innovation Center (ChemBIC), School of Chemistry and Chemical Engineering, Nanjing University, Nanjing, China.

Viral adhesion to host cells is a critical step in infection for many viruses, including monkeypox virus (MPXV). In MPXV, the H3 protein mediates viral adhesion through its interaction with heparan sulfate (HS), yet the structural details of this interaction have remained elusive. Using AI-based structural prediction tools and molecular dynamics (MD) simulations, we identified a novel, positively charged α-helical domain in H3 that is essential for HS binding.

January 2025

Department of Pediatric Surgery, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, No. 1095 Jiefang Avenue, Qiaokou District, Wuhan, Hubei 430030, China.

Hirschsprung's disease (HSCR) is a congenital enteric neuropathic disorder characterized by high heritability (>80%) and polygenic inheritance (>20 genes). The previous genome-wide association studies (GWAS) identified several common variants associated with HSCR and demonstrated increased predictive performance for HSCR risk in Europeans using a genetic risk score, there remains a notable gap in knowledge regarding Chinese populations. We conducted whole exome sequencing in a HSCR case cohort in Chinese.

Biomed Opt Express

January 2025

Athinoula A. Martinos Center for Biomedical Imaging, Department of Radiology, Massachusetts General Hospital, Harvard Medical School, Charlestown, MA 02129, USA.

Two-photon phosphorescence lifetime microscopy has been a key tool for studying cerebral oxygenation in mice. However, the accuracy of the partial pressure of oxygen (pO) measurements is affected by out-of-focus signal. In this work, we applied reconfigurable differential aberration imaging to characterize and correct for out-of-focus signal contamination in intravascular pO imaging.

PROTAR Vaccine 2.0 generates influenza vaccines by degrading multiple viral proteins.

Nat Chem Biol

January 2025

State Key Laboratory of Quantitative Synthetic Biology, Shenzhen Institute of Synthetic Biology, Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences, Shenzhen, China.

Manipulating viral protein stability using the cellular ubiquitin-proteasome system (UPS) represents a promising approach for developing live-attenuated vaccines. The first-generation proteolysis-targeting (PROTAR) vaccine had limitations, as it incorporates proteasome-targeting degrons (PTDs) at only the terminal ends of viral proteins, potentially restricting its broad application. Here we developed the next-generation PROTAR vaccine approach, referred to as PROTAR 2.

The ER protein CANX (calnexin)-mediated autophagy protects against alzheimer disease.

Autophagy

January 2025

Guangdong Key Laboratory of Age-Related Cardiac and Cerebral Diseases, Department of Neurology, Affiliated Hospital of Guangdong Medical University, Zhanjiang, China.

Although the relationship between macroautophagy/autophagy and Alzheimer disease (AD) is widely studied, the underlying mechanisms are poorly understood, especially the regulatory role of the initiation signaling of autophagy on AD. Here, we find that the ER transmembrane protein CANX (calnexin) is a novel interaction partner of the autophagy-inducing kinase ULK1 and is required for ULK1 recruitment to the ER under basal or starved conditions. Loss of CANX results in the inactivity of ULK1 kinase and inhibits autophagy flux.

The two contradictory entities in nature often follow the principle of unity of opposites, leading to optimal overall performance. Particularly, aggregation-induced emission luminogens (AIEgens) with donor-acceptor (D-A) structures exhibit tunable optical properties and versatile functionalities, offering significant potential to revolutionize cancer treatment. However, trapped by low molar absorptivity (ε) owing to the distorted configurations, the ceilings of their photon-harvesting capability and the corresponding phototheranostic performance still fall short.

Smart and Noninvasive SERS Immunosensors for Monitoring Dynamic Expression of Cytokines during Cell Pyroptosis.

Anal Chem

January 2025

Guangdong Key Laboratory of Biomedical Measurements and Ultrasound Imaging, School of Biomedical Engineering, Shenzhen University Medical School, Shenzhen University, Shenzhen 518060, PR China.

Accompanying the occurrence of inflammatory reaction to release cytokines, pyroptosis can activate an immune response for resistance against cancer. Consequently, elevated levels of cytokines released by cancer cells are highly correlated with the effectiveness of cancer treatment. Herein, a noninvasive surface-enhanced Raman spectroscopy (SERS) immunosensor was developed to sensitively and specifically measure the tumor necrosis factor-α (TNF-α), a proinflammatory cytokine, during the cell pyroptosis process.
