Adrenaline May Contribute to Prothrombotic Condition via Augmentation of Platelet Procoagulant Response, Enhancement of Fibrin Formation, and Attenuation of Fibrinolysis. Front Physiol 2021; 12:657881.

Abstract
Background: Adrenaline is believed to play a role in thrombosis and hemostasis. The complex effect of its clinically relevant concentrations on thrombus formation, coagulation and fibrinolysis in human blood has never been specifically studied. Methods: Confocal microscopy was used to study thrombus formation under flow, exposure of phosphatidylserine (PS) in adhered platelets, to evaluate clots density, and to measure kinetics of fibrin formation and external fibrinolysis under flow. Flow cytometry was utilized to assess PS exposure in non-adhered platelets. Kinetics of clot formation and internal fibrinolysis was evaluated by thromboelastometry. Platelet aggregation was measured by optical aggremometry. Kinetics of clot retraction was assessed by using digital camera. Results: We found that adrenaline (1-10 nM) is able to enhance platelet activation evoked by subthreshold collagen (150 ng/ml), resulting in augmentation of platelet aggregation, thrombus formation under arterial flow conditions, platelet PS exposure, and formation of platelet-fibrin clots. The development of platelet procoagulant response evoked by adrenaline + low collagen was associated with the formation of denser platelet-fibrin clots and the decrease in rate of fibrinolysis despite whether lysis was initiated inside (internal fibrinolysis) or outside the clot (external fibrinolysis). The above phenomena were abolished by the α2-adrenergic receptor antagonist, rauwolscine. Adrenaline-collagen synergism, expressed as PS exposure, was significantly reduced by cyclooxygenase inhibitor (acetylsalicic acid), GPIIb/IIIa receptor blocker (tirofiban), and P2Y12 receptor antagonist (PSB 0739). Conclusion: Clinically relevant concentrations of adrenaline may significantly augment responses of human platelets in the presence of subthreshold concentrations of collagen, which should be considered during therapies involving adrenaline infusion. Routinely used antiplatelet drugs may reduce the prothrombotic state evoked by adrenaline-collagen synergism.

Pulmonary platelet accumulation induced by catecholamines: Its involvement in lipopolysaccharide-induced anaphylaxis-like shock. Int Immunopharmacol 2016; 43:40-52. [PMID: 27939824 DOI: 10.1016/j.intimp.2016.11.034] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2016] [Revised: 10/29/2016] [Accepted: 11/29/2016] [Indexed: 11/15/2022]
Abstract
Intravenously injected lipopolysaccharides (LPS) rapidly induce pulmonary platelet accumulation (PPA) and anaphylaxis-like shock (ALS) in mice. Macrophages reportedly release catecholamines rapidly upon stimulation with LPS. Here, we examined the involvement of macrophage-derived catecholamines in LPS-induced PPA and ALS. A catecholamine or Klebsiella O3 (KO3) LPS was intravenously injected into mice, with 5-hydroxytryptamine in the lung being measured as a platelet marker. The tested catecholamines induced PPA, leading to shock. Their minimum shock-inducing doses were at the nmol/kg level. The effects of epinephrine and norepinephrine were inhibited by prazosin (α1 antagonist) and by yohimbine (α2 antagonist), while dopamine's were inhibited only by prazosin. Use of synthetic adrenergic α1- and/or α2-agonists, platelet- or macrophage-depleted mice, a complement C5 inhibitor and C5-deficient mice revealed that (a) α2-receptor-mediated PPA and shock depend on both macrophages and complements, while α1-receptor-mediated PPA and shock depend on neither macrophages nor complements, (b) the PPA and ALS induced by KO3-LPS depend on α1- and α2-receptors, macrophages, and complements, and (c) KO3-LPS-induced PPA is preceded by catecholamines decreasing in serum. Together, these results suggest the following. (i) Catecholamines may stimulate macrophages and release complement C5 via α2-receptors. (ii) Macrophage-derived catecholamines may mediate LPS-induced PPA and ALS. (iii) Moderate PPA may serve as a defense mechanism to remove excess catecholamines from the circulation by promoting their rapid uptake, thus preventing excessive systemic effects. (iv) The present findings might provide an insight into possible future pharmacological strategies against such diseases as shock and acute respiratory distress syndrome.
