Complement activation drives the phagocytosis of necrotic cell debris and resolution of liver injury.
Front Immunol
January 2025
Laboratory of Molecular Immunology, Department of Microbiology, Immunology and Transplantation, Rega Institute for Medical Research, KU Leuven, Leuven, Belgium.
Cells die by necrosis due to excessive chemical or thermal stress, leading to plasma membrane rupture, release of intracellular components and severe inflammation. The clearance of necrotic cell debris is crucial for tissue recovery and injury resolution, however, the underlying mechanisms are still poorly understood, especially . This study examined the role of complement proteins in promoting clearance of necrotic cell debris by leukocytes and their influence on liver regeneration.

Mov Disord Clin Pract
January 2025
Parkinson Disease and Movement Disorders Center, University of Pennsylvania, Philadelphia, Pennsylvania, USA.
Background: Dystonia may respond to VMAT2 inhibition.
Objectives: Providing pilot data on the safety, tolerability, and efficacy of deutetrabenazine in non dopa-responsive dystonia.
Methods: Deutetrabenazine was titrated by adults with isolated dystonia.
Primary Iliopsoas Abscess and Drug-Induced Liver Injury in the Emergency Department: A Case Report.
Diseases
December 2024
Department of Cardiology, "Victor Babes" University of Medicine and Pharmacy, E. Murgu Square No. 2, 300041 Timisoara, Romania.
Background And Objective: Iliopsoas abscess (IPA) is a rare condition with varied symptomology and etiology. Less than one-third of patients with IPA present in the emergency department (ED) with the traditional triad of fever, back pain, and restricted hip motion (or limp), leading to delays in diagnosis and management. Acute liver failure is also a rare clinical presentation in the ED, being associated with high morbidity and mortality.

Eur J Pharmacol
January 2025
State Key Laboratory of Pharmaceutical Biotechnology, School of Life Sciences, Nanjing University, Nanjing, Jiangsu, 210023, China; Chemistry and Biomedicine Innovative Center, Nanjing University, Nanjing, Jiangsu, 210023, China. Electronic address:
Full-thickness skin grafts often face challenges related to inefficient vascularization in clinical settings. Senescent cells, known for secreting various growth factors, have demonstrated excellent effects on angiogenesis. In this study, we induced senescence in a subset of fibroblasts in the donor dermis by co-administering trametinib and palbociclib before harvesting the skin grafts for transplantation.

Toxicol Sci
December 2024
Laboratory of Molecular Pharmacokinetics, Graduate School of Pharmaceutical Sciences, The University of Tokyo, Tokyo, Japan.
Drug-induced emesis is one of the major symptoms of gastrointestinal toxicity. Preclinical risk assessment of emesis has been challenging owing to the lack of suitable animal models or in vitro assay systems. One of the triggers of emesis is an excessive serotonin (5-HT) release from enterochromaffin (EC) cells in the intestinal tract, which activates the vomiting center in the brain stem and elicits the vomiting reflex.
