An inflammatory state defines a high-risk T-lineage acute lymphoblastic leukemia subgroup.
Sci Transl Med
January 2025
Princess Margaret Cancer Centre, University Health Network, Toronto, ON M5G 2C4, Canada.
Article Synopsis
- T-lineage acute lymphoblastic leukemia (ALL) presents as an aggressive cancer with diverse subtypes, making traditional classification difficult.
- A multiomics analysis of bone marrow samples revealed a specific subset of T-lineage ALL with active inflammatory and stem gene programs, showing unique biological and treatment response characteristics.
- A computational inflammatory gene signature scoring system was developed to better classify patients, identifying a high-risk subtype that could guide targeted therapies for more effective treatment approaches.
Combined Use of Intranasal Methylprednisolone and Allopregnanolone: Revisiting Anti-inflammatory and Remyelinating Treatment in a Murine Model of Multiple Sclerosis.
Front Biosci (Landmark Ed)
December 2024
Department of Immunology, Institute of Biomedical Research Universidad Nacional Autónoma de México, UNAM, 04510 Mexico City, Mexico.
Background: Multiple sclerosis (MS) is a demyelinating, neuroinflammatory, progressive disease that severely affects human health of young adults. Neuroinflammation (NI) and demyelination, as well as their interactions, are key therapeutic targets to halt or slow disease progression. Potent steroidal anti-inflammatory drugs such as methylprednisolone (MP) and remyelinating neurosteroids such as allopregnanolone (ALLO) could be co-administered intranasally to enhance their efficacy by providing direct access to the central nervous system (CNS).

Front Cell Infect Microbiol
December 2024
Clinical and Research Infectious Diseases Department, National Institute for Infectious Diseases Lazzaro Spallanzani Istituto di Ricovero e Cura a Carattere Scientifico (IRCCS), Rome, Italy.
Article Synopsis
- The pathogenesis of long COVID (LC) involves uncertainty, complicating the search for effective therapies.
- The hypothesis suggests that chronic damage to the body's anti-inflammatory mechanisms, particularly through the vagus nerve, HPA axis, and mitochondrial function, plays a crucial role in LC development.
- The theory posits that SARS-CoV-2 alters these systems at various levels, leading to persistent inflammation due to impaired anti-inflammatory responses from acetylcholine and cortisol, warranting further investigation into glucocorticoid receptor sensitivity and potential long-term epigenetic effects.
The fungicide propiconazole induces hepatic steatosis and activates PXR in a mouse model of diet-induced obesity.
Arch Toxicol
December 2024
Nutrition, Metabolism and Genomics Group, Division of Human Nutrition and Health, Wageningen University, Wageningen, The Netherlands.
Propiconazole is a triazole fungicide previously shown to induce triglyceride accumulation in human liver HepaRG cells, potentially via activation of the Pregnane X Receptor (PXR). However, whether propiconazole can disrupt hepatic and whole-body metabolism in vivo is currently unknown. Therefore, we aimed to examine the metabolic effects of propiconazole in the context of metabolic dysfunction-associated steatotic liver disease (MASLD), obesity, and insulin resistance.

Department of Neurology, The First Affiliated Hospital, Guangdong Provincial Key Laboratory of Diagnosis and Treatment of Major Neurological Diseases, National Key Clinical Department and Key Discipline of Neurology, Sun Yat-Sen University, No. 58 Zhongshan Road 2, Guangzhou, 510080, China.
Background: Neuromyelitis Optica Spectrum Disorders (NMOSD) comprise a group of autoimmune-mediated, inflammatory, demyelinating central nervous system diseases caused by aquaporin-4 (AQP4) IgG autoantibodies. Efgartigimod is a human IgG Fc fragment that reduces antibody titers by targeting the neonatal Fc receptor (FcRn). This study documents the efficacy of efgartigimod combined with intravenous methylprednisolone (IVMP) in the acute phase of NMOSD.
