The α2-adrenergic receptors are cell surface proteins expressed in several cell-types including macrophages to which recent evidence suggests that they play an important role in the modulation of inflammation. This study aimed to investigate the role of α2-adrenergic receptors in macrophage activation, survival, and cytokine production.

In the air pouch model, an acute mouse model of inflammation, guanfacine, an α2 adrenergic agonist, reduces myeloid cell infiltration and levels of pro-inflammatory cytokines by specifically targeting the α2A adrenergic receptor subtype. In the K/BxN arthritis mouse model, guanfacine significantly modulated the clinical and functional outcome of arthritis.

Radial blood pressure waveforms were recorded for 1 min in 203 individuals who received the vaccine at a medical center. Participants were categorized into four groups: no side effects (n = 18), cardiac side effects (n = 45), vascular side effects (n = 68), and combined cardiac or vascular side effects (n = 72). Spectral analysis was performed on 40 harmonic indices derived from the pulse waveform, including amplitude proportions, phase angles, and variability indices. These features were analyzed using both a self-developed pulse distribution method and a standard machine learning (ML) algorithm. Significant changes in spectral indices were observed post-vaccination. The pulse distribution method achieved an area under the curve (AUC) of 0.76 in detecting cardiovascular side effects, outperforming the ML approach. The performance was not significantly influenced by potential confounders. These findings suggest that vaccine-induced vascular stiffness may cause a mismatch in elastic properties of the vasculature, and that spectral analysis of the arterial pulse may offer a noninvasive approach to assess such changes.</p>","PeriodicalId":12004,"journal":{"name":"European journal of pharmacology","volume":" ","pages":"178269"},"PeriodicalIF":4.7,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145328490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
