Serum adipsin levels in rheumatic diseases: defining its role in disease activity and progression in rheumatoid arthritis and axial spondyloarthritis.

Rheumatoid arthritis (RA) and axial spondyloarthritis (axSpA) are the most common rheumatic diseases (RDs). They are characterised by chronic inflammation of the joints and musculoskeletal components. Adipose tissue releases adipokines that regulate numerous biological processes, including inflammation, thus stabilising the relationship between RDs and adipokines, such as adiponectin and leptin. The correlation between these adipokines and RA highlights a possible role of other adipokines in RDs. Therefore, we decided to analyse the role of the adipokine adipsin in the context of RDs. Adipsin …

Dietary methionine restriction (MR) produces multiple metabolic health benefits and extends the healthspan of several model organisms, inclu … so propose a model for the mechanistic basis of such benefits, which involves reduced activation of leptin-responsive pro-inflammatory pathways.

Adaptive Responses in Severe Acute Malnutrition: Endocrinology, Metabolomics, Mortality, and Growth.

Malnutrition afflicts millions of the world's children and predisposes to death from diarrhea and infectious diseases. Children with severe … in, red blood cells, and renal medulla and conserve muscle mass. White adipose tissue also secretes leptin, which facilitates the immune response and may protect against mortality from infection. Euglycemia and survival in SAM are thereby prioritized over linear growth, which is suppressed owing to inhibition of insulin-like growth factor 1 production an …

Полиморфизм меланкортина - генезиалы с воспалением и болезнями.

Рецепторы Меланокортина (МКР) выполняют различные функции: от пигментации кожи, регулирования аппетита, реакции на стресс и когниции, синтеза стероидов и энергетического баланса до регенерации клеток и иммуномодуляции. Генетический полиморфизм с распределением тканей от мозга, лимбической системы и адренальной коры до нейтрофилов, моноцитов и макрофазов проявляется в MCR. Мутации в генах MC1R, MC2R, MC3R и MC4R связаны с риском меланомы, семейной глюкокортикоидной недостаточности, ожирения и типа 2 Диафиозный сахар, соответственно. Тем временем, MC1R, MC2R и MC5R связаны с риском серьезного де

Comprehensive analysis of peripheral blood free amino acids in MASLD: the impact of glycine-serine-threonine metabolism.

Little is known about how blood free amino acids (FAAs) change in metabolic dysfunction-associated steatotic liver disease (MASLD). This stu … enhanced glycolysis via pyruvate. High-Gly, Ser, and Thr diet ameliorated pathogenesis of MASLD in leptin-deficient mice. Most FAAs increase due to cardiometabolic abnormalities, particularly IR. However, interventions targeting the metabolism of Gly, Ser, and Thr have the potential to improve MASLD.
