- Acetaminophen (APAP) is a widely used analgesic and antipyretic agent that is safe at therapeutic doses. However, due to its extensive misuse, APAP-induced liver injury has become a major public health concern. Although mesenchymal stem/stromal cells (MSCs) represent a promising emerging therapy for APAP-induced liver injury, considerable research has focused on enhancing their efficacy, notably through genetic modification. Fibroblast growth factor 21 (FGF21), an endocrine hormone activated by metabolic stress, is known to regulate energy homeostasis, glucose and lipid metabolism, and to promote the homing of MSCs to sites of injury. Consequently, this study was designed to determine whether genetically engineering MSCs to overexpress FGF21 (FGF21-MSCs) augments their therapeutic potential against APAP-induced acute liver injury (ALI). - Source: PubMed

Host factors including enteric dysfunction, systemic inflammation, and nutritional status may influence responses, yet their role in shaping OCV immune responses is not fully understood. This study examined associations between pre-vaccination biomarkers spanning these domains and vibriocidal seroconversion to an OCV, while characterizing how the same biomarker profiles are altered during acute natural infection. - Source: PubMed

However, the mechanisms behind this phenomenon are not well understood. Here, using genetic loss-of-function models for fibroblast growth factor 21 (Fgf21) and its obligate co-receptor β-Klotho (Klb), we demonstrate that FGF21-KLB signalling in adipocytes is indispensable for the anti-senescence effects of PR. Specifically, adipocyte FGF21 signalling preserves mitochondrial integrity, maintains an anti-inflammatory milieu and sustains nicotinamide adenine dinucleotide (NAD) homeostasis under PR. Mechanistically, FGF21 enhances adipocyte NAD abundance through activation of AMP-activated protein kinase to maintain mitochondrial integrity. Additionally, high-protein feeding induces adipocyte senescence and metabolic dysfunction could be mitigated by exogenous FGF21 supplementation. Together, these findings establish adipose FGF21 signalling as a pivotal endocrine axis that couples dietary protein availability to adipocyte NAD metabolism and identify it as a promising target for the prevention and treatment of age-related metabolic disorders. KEY POINTS: Dietary protein restriction improves metabolic health and extends lifespan, but the mechanisms responsible for these benefits are not fully understood. Fibroblast growth factor 21 (FGF21) is a hormone strongly induced by low-protein diets and has emerged as an important regulator of metabolic adaptation. We show that FGF21 signalling specifically in adipose tissue is essential for the anti-senescence effects of dietary protein restriction. FGF21 preserves mitochondrial integrity by maintaining nicotinamide adenine dinucleotide metabolism through AMP-activated protein kinase activation. Targeting the FGF21-adipose tissue pathway may provide new strategies to prevent or treat age-related metabolic dysfunction. - Source: PubMed

The persistently high global prevalence of childhood undernutrition and consequent stunting underscores the urgent need to better understand how nutritional status shapes developmental trajectories. Biological sex has recently emerged as a key risk factor for stunting, with boys consistently exhibiting greater vulnerability. This review examines the biological basis of sex differences in physiological adaptation to nutritional stress, focusing specifically on dietary protein deficiency during the juvenile period. Two critical developmental processes display pronounced sexual dimorphism under protein restriction: linear growth and reproductive maturation. Evidence from both preclinical and clinical studies indicates that juvenile protein restriction differentially affects these processes in males and females, highlighting the necessity of considering sex as a biological variable in experimental design and data interpretation. Shared endocrine signals, including Fibroblast Growth Factor 21, may contribute to these sex-specific adaptive responses. Further elucidating the nutritional, endocrine and metabolic mechanisms underlying sexually dimorphic outcomes of juvenile development is essential for enhancing the mechanistic value and translational relevance of preclinical and clinical research. - Source: PubMed
