However, two β-AR antagonists, carvedilol and nebivolol, can attenuate the formation of the NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasome. Many β-AR agonists have proved to mediate anti-inflammatory signals, especially in regard to suppressing the inflammatory response of macrophages or providing protective effects in cases of hypoxia. The activation of beta-adrenergic receptors can, however, be a double-edged sword, as their overactivation may result in cardiac inflammation.

Adrenergic signaling has traditionally been described to be immunosuppressive, but some recent results are challenging this paradigm, in particular those related to <em>in vivo</em> models of stress and findings in human patients. Also, cumulative evidence reveals that the final pro- or anti-inflammatory outcome of adrenergic inputs in myeloid cells appears to be very dependent on the experimental setup utilized or on the cellular context (resting vs stimulated conditions, <em>in vivo</em> vs <em>in vitro</em> settings, mice vs human cells, health vs pathology). Varying doses and/or time points may result in seemingly contradictory results that depend on the nature of receptor engaged (α or β adrenergic receptor subtypes), the downstream cascades involved, the presence of additional stimulatory or inhibitory signals, and the actual kinetics of the process studied. We will thus address some of these apparently paradoxical findings, review several pathological settings in which adrenergic modulation of neutrophil or macrophage-mediated immunity is relevant, and discuss open questions that still remain unanswered.</div></div>","PeriodicalId":52156,"journal":{"name":"Current Opinion in Physiology","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142416297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
