Exploring TNFR1: from discovery to targeted therapy development.
J Transl Med
January 2025
School of Medicine, Shanghai Baoshan Luodian Hospital, Shanghai University, Shanghai, 201908, China.
This review seeks to elucidate the therapeutic potential of tumor necrosis factor receptor 1 (TNFR1) and enhance our comprehension of its role in disease mechanisms. As a critical cell-surface receptor, TNFR1 regulates key signaling pathways, such as nuclear factor kappa-B (NF-κB) and mitogen-activated protein kinase (MAPK), which are associated with pro-inflammatory responses and cell death. The intricate regulatory mechanisms of TNFR1 signaling and its involvement in various diseases, including inflammatory disorders, infectious diseases, cancer, and metabolic syndromes, have attracted increasing scholarly attention.

J Cardiothorac Surg
January 2025
The First Hospital of Lanzhou University, Lanzhou, China.
Background: This article aims to use high-throughput sequencing to identify miRNAs associated with ferroptosis in myocardial ischemia-reperfusion injury, select a target miRNA, and investigate its role in H9C2 cells hypoxia-reoxygenation injury.
Methods: SD rats and H9C2 cells were used as subjects. ELISA kits quantified MDA, SOD, GSH, LDH, and ferritin levels.
Clinical outcome changes in sarcopenic obesity: a meta-analysis of exercise training methods.
BMC Geriatr
January 2025
The First Affiliated Hospital of Zhejiang Chinese Medical University (Zhejiang Provincial Hospital of Chinese Medicine), 54 Youdian Road, Hangzhou, Zhejiang Province, 310053, China.
Aim: Assessing the effect of various forms of exercise training on patients with sarcopenic obesity.
Methods: Two independent reviewers systematically searched English and Chinese databases (PubMed, Embase, Cochrane Library, Web of Science, CNKI) for randomized controlled trials on various exercise training effects in sarcopenic obesity patients until October 2023. Reference materials and grey literature were also included.
Opportunities and limitations of B cell depletion approaches in SLE.
Nat Rev Rheumatol

B cell depletion with rituximab, a chimeric monoclonal antibody that selectively targets B cells by binding CD20, has been used off label in severe and resistant systemic lupus erythematosus (SLE) for over two decades. Several biological mechanisms limit the efficacy of rituximab, including immunological reactions towards the chimeric molecule, increased numbers of residual B cells, including plasmablasts and plasma cells, and a post-treatment surge in B cell-activating factor (BAFF) levels. Consequently, rituximab induces remission in only a proportion of patients, and safety issues limit its use.

The hippocampus (HPC) has emerged as a critical player in the control of food intake, beyond its well-known role in memory. While previous studies have primarily associated the HPC with food intake inhibition, recent research suggests a role in appetitive processes. Here we identified spatially distinct neuronal populations within the dorsal HPC (dHPC) that respond to either fats or sugars, potent natural reinforcers that contribute to obesity development.
