Background: Although physical exercise acutely increases the most widely used inflammatory biomarkers, there is no information on its effect on soluble urokinase plasminogen activating receptor (suPAR), a circulating biomarker increasingly used for the assessment of systemic inflammation.
Methods: suPAR was assessed with the quantitative suPARnostic Standard ELISA Assay (Virogates, Birkerød, Denmark) in 12 professional football players before and after a football match. The athletes were divided into two experimental groups. An oral dose of 300 mg of allopurinol was administered to one group of six participants four hours before a match; the other six participants received placebo.
Results: Serum suPAR concentration did not vary significantly after the match in both the placebo and allopurinol group. No significant differences were observed between placebo and allopurinol groups at baseline and after the game.
Conclusions: At variance with other consolidated inflammatory biomarkers, suPAR is not influenced by either physical exercise or administration of xanthine oxidase inhibitors.

Associations between social behaviour and proinflammatory immune activation are modulated by age in a free-ranging primate population.

The effect of the social environment on the proinflammatory immune response may mediate the relationship between social environment and fitness but remains understudied outside captive animals and human populations. Age can also influence both immune function and social behaviour, and hence may modulate their relationships. This study investigates the role of social interactions in driving the concentrations of two urinary markers of proinflammatory immune activation, neopterin and soluble urokinase plasminogen activator receptor (suPAR), in a free-ranging population of rhesus macaques, .

Psilocybin represents a novel therapeutic approach for individuals with major depressive disorder (MDD) who do not respond to conventional antidepressant treatment. Investigating the influence of psilocybin on the pathophysiological processes involved in MDD could enhance our neurobiological understanding of the presumed antidepressant action mechanism. This systematic review aims to summarize the results of human studies investigating changes in blood-based biomarkers of MDD to guide future research on potentially relevant analytes that could be monitored in clinical trials.

Introduction: We investigated the specific factors driving abnormal angiogenesis in Alzheimer's disease (AD) and its role in cerebrovascular lesions and neurodegeneration.
Methods: We assessed cerebrovascular pathologies, amyloid-beta (Aβ), and tau pathologies in post mortem human brains and detected 12 angiogenic factors in cerebrospinal fluid (CSF) from the China Aging and Neurodegenerative Disease Initiative (CANDI) cohort.
Results: We observed severe blood-brain barrier damage and elevated levels of the vascular marker CD31 in human AD brains, which had a stronger correlation with tau pathology than Aβ pathology.
Proteomics-Based Soluble Urokinase Plasminogen Activator Receptor Levels Are Associated With Incident Heart Failure Risk.
JACC Adv

Emory University School of Medicine, Division of Cardiology, Department of Medicine, Atlanta, Georgia, USA.
Background: Higher soluble urokinase plasminogen activator receptor (suPAR) levels are associated with adverse outcomes in chronic heart failure (HF).
Objectives: The authors assessed the association between proteomics-based suPAR levels and incident HF risk in the general population.
Methods: In 40,418 UK Biobank participants without HF or coronary artery disease at enrollment, the association between Olink-based suPAR levels measured as relative protein expression levels and incident all-cause, ischemic, and nonischemic HF was analyzed by competing-risk regression, while accounting for all-cause death as a competing risk.
Inflammatory Markers and Measures of Cardiovascular Autonomic Neuropathy in Type 1 Diabetes.

Background: Cardiovascular autonomic neuropathy (CAN) and inflammation predict more severe outcomes in type 1 diabetes (T1D). However, the link between CAN and inflammation in T1D remains unclear. We examined associations between CAN measures and inflammatory biomarkers in individuals with T1D.
