The interaction between central and peripheral immune systems in methamphetamine use disorder: current status and future directions

Journal of Neuroinflammation, Journal Year: 2025, Volume and Issue: 22(1)

Published: Feb. 15, 2025

Methamphetamine (METH) use disorder (MUD) is characterized by compulsive drug-seeking behavior and substantial neurotoxicity, posing a considerable burden on individuals society. Traditionally perceived as localized central nervous system disorder, recent preclinical clinical studies have elucidated that MUD multifaceted influenced various biological systems, particularly the immune system. Emerging evidence suggests both peripheral responses play crucial role in initiation persistence of MUD. Conceptualizing it systemic process prompts significant inquiries regarding mechanisms communication between compartments. Also, whether this intercommunication could serve diagnostic biomarkers or therapeutic targets. This review begins offering an overview mechanistic pertaining to neuroimmune systems. Finally, future directions are suggested through integration innovative technologies multidimensional data promote translation basic research into interventions.

Paraventricular nucleus CRH neurons regulate acute lung injury via sympathetic nerve–neutrophil axis

Research Square (Research Square), Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 5, 2025

Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are severe conditions with high morbidity mortality, effective treatments limited. Neuroimmune interactions play a critical role in homeostasis, but it remains unclear if specific brain regions regulate inflammation. Here, we unveil the of neuroimmune signaling ALI, focusing on regulatory function corticotropin-releasing hormone (CRH) neurons paraventricular nucleus (PVN) hypothalamus. Using viral tracing, chemogenetic modulation, pharmacological interventions mouse models ALI induced by intranasal lipopolysaccharide cecal ligation puncture (CLP), found that activated CRH^PVN projected to lung. Activation these protected mice from death, reducing neutrophil infiltration effector functions In contrast, inhibiting exacerbated ALI. Notably, beneficial impact neuron activation is compromised pulmonary chemical sympathectomy or inhibition β₂-adrenergic receptor. These protective effects were dependent sympathetic nerves, norepinephrine released locally modulate via β₂-AR–β-arrestin2 signaling, NF-κB pathway. Our findings reveal brain-lung axis regulates immune responses suggesting novel therapeutic targets for ARDS.

Introduction Sepsis associated thrombocytopenia (SAT) is a common complication of sepsis. We designed this study to investigate factors influencing SAT. Methods Patients with sepsis (2984 in Peking union medical college hospital [PUMCH] database, 13165 eICU Collaborative Research [eICU] 11101 Medical Information Mart for Intensive Care IV [MIMIC-IV] database) were enrolled.

Plastic sex-trait modulation by differential gene expression according to social environment in male red deer

BMC Genomics, Journal Year: 2025, Volume and Issue: 26(1)

Mate competition encourages individuals to modulate characters involved in mating success. Adult Iberian red deer (Cervus elaphus hispanicus) males show a dark ventral patch (DVP) that plays central role rivalry, whose size and chemical compounds varied according the level of male-male within population. In pigmentation DVP appears, after urinary excretion, molecule called DOPEG originating from metabolism norepinephrine, leading us investigate whether differential expression mechanisms key genes dopamine B-hydroxylase (DBH) tyrosine hydroxylase (TH), encoding enzymes catalyzing process can be sensitive different competitive population situations responsible for plastic development deer. We found social environment with higher intrasexual competition, where male invest more sexual traits, was associated increased levels DBH TH transcripts, while Dopamine showed reversed values. alternative splicing gene, although differences between environments appeared just related levels. Our results support internal cause trait modulation based on gene relation conditions environment. propose quantification transcripts as molecular biomarker reproductive activity.

Early fluid plus norepinephrine resuscitation diminishes kidney hypoperfusion and inflammation in septic newborn pigs

Shock, Journal Year: 2024, Volume and Issue: unknown

Published: April 23, 2024

Sepsis is the most frequent risk factor for acute kidney injury (AKI) in critically ill infants. Sepsis-induced dysregulation of microcirculation newborns unresolved. The objective this study was to use translational swine model evaluate changes function during early phase sepsis and impact fluid plus norepinephrine resuscitation. Newborn pigs (3-7-day-old) were allocated randomly three groups: 1) sham, 2) (cecal ligation puncture) without subsequent resuscitation, 3) with lactated Ringer All animals underwent standard anesthesia mechanical ventilation. Cardiac output glomerular filtration rate measured noninvasively. Mean arterial pressure, total renal blood flow, cortical perfusion, medullary tissue oxygen tension (mtPO 2 ) determined 12 h. Cecal puncture decreased mean pressure cardiac by more than 50%, a proportional increase vascular resistance 60-80% reduction mtPO compared sham. also ~79% increased AKI biomarkers. Isolated foci tubular necrosis observed septic piglets. Except , all these parameters ameliorated resuscitated Resuscitation attenuated sepsis-induced increases levels plasma C-reactive protein, proinflammatory cytokines, lactate dehydrogenase, alanine transaminase, aspartate aminotransferase, NLRP3 inflammasome. These data suggest that newborn subjected cecal develop hypodynamic AKI. Early implementation resuscitation lessens degree inflammation, AKI, liver injury.
