Iron improves the antiviral activity of NK cells.
Front Immunol
January 2025
Institute for Virology, University Hospital Essen, University of Duisburg-Essen, Essen, Germany.
Natural killer (NK) cells are innate immune cells that play a crucial role as a first line of defense against viral infections and tumor development. Iron is an essential nutrient for immune cells, but it can also pose biochemical risks such as the production of reactive oxygen species. The importance of iron for the NK cell function has gained increasing recognition.

BMC Med
January 2025
Department of Epidemiology/Department of Maternal, Child and Adolescent Health, School of Public Health, Qilu Hospital, Shandong University, Jinan, Shandong, China.
Background: Mechanisms underlying the association of life-course adiposity with incident hypertension in adulthood have not been comprehensively investigated. In this study, we aimed to investigate the potential biochemical and metabolomic mechanisms underlying the association between adiposity and incident hypertension.
Methods: A total of 180,527 participants from the UK Biobank aged 37 to 73 years were included.
Extracellular acyl-CoA-binding protein as an independent biomarker of COVID-19 disease severity.
Front Immunol
January 2025
Inflammation and Immunity in Global Health Program, Research Institute of the McGill University Health Centre, Montreal, QC, Canada.
Background: Factors leading to severe COVID-19 remain partially known. New biomarkers predicting COVID-19 severity that are also causally involved in disease pathogenesis could improve patient management and contribute to the development of innovative therapies. Autophagy, a cytosolic structure degradation pathway is involved in the maintenance of cellular homeostasis, degradation of intracellular pathogens and generation of energy for immune responses.

Transl Lung Cancer Res
December 2024
Department of Medicine and Cancer Center, Massachusetts General Hospital, Boston, MA, USA.
For over a century, we have appreciated that the biochemical processes through which micro- and macronutrients are anabolized and catabolized-collectively referred to as "cellular metabolism"-are reprogrammed in malignancies. Cancer cells in lung tumors rewire pathways of nutrient acquisition and metabolism to meet the bioenergetic demands for unchecked proliferation. Advances in precision medicine have ushered in routine genotyping of patient lung tumors, enabling a deeper understanding of the contribution of altered metabolism to tumor biology and patient outcomes.

Front Vet Sci
December 2024
Laboratory of Inflammation Pharmacology and Immunometabolism, Institute of Pharmacology and Morphophysiology, Faculty of Veterinary Sciences, Universidad Austral de Chile, Valdivia, Chile.
D-lactic acidosis is associated with fermentative disturbances and is often marked by elevated levels of D-lactic acid in the blood, ruminal fluid, and synovial fluid in cattle. D-lactic acidosis is linked to various inflammatory manifestations, and although the causative factors have been extensively explored, the exact pathogenesis of the associated inflammation remains elusive. Notably, less attention has been given to D-lactate, a stereoisomer found in the plasma of affected animals, which may lead to D-lactic acidosis.
