功能描述

Thrombin, which cleaves bonds after Arg and Lys, converts fibrinogen to fibrin and activates factors V, VII, VIII, XIII, and, in complex with thrombomodulin, protein C. Functions in blood homeostasis, inflammation and wound healing. Activates coagulation factor XI (F11); activation is promoted by the contact with negatively charged surfaces (PubMed:2019570, PubMed:21976677). Triggers the production of pro-inflammatory cytokines, such as MCP-1/CCL2 and IL8/CXCL8, in endothelial cells (PubMed:30568593, PubMed:9780208)
凝血酶在精氨酸和赖氨酸后裂解键，将纤维蛋白原转化为纤维蛋白，并激活因子 V、VII、VIII、XIII，并与血栓调节蛋白复合，激活蛋白 C。在血液稳态、炎症和伤口愈合中发挥作用。 激活凝血因子 XI (F11)； 与带负电的表面接触会促进激活（PubMed：2019570，PubMed：21976677）。 触发内皮细胞中促炎细胞因子的产生，例如 MCP-1/CCL2 和 IL8/CXCL8 (PubMed:30568593、PubMed:9780208)

Factor II deficiency

A very rare blood coagulation disorder characterized by mucocutaneous bleeding symptoms. The severity of the bleeding manifestations correlates with blood factor II levels.

Ischemic stroke

A stroke is an acute neurologic event leading to death of neural tissue of the brain and resulting in loss of motor, sensory and/or cognitive function. Ischemic strokes, resulting from vascular occlusion, is considered to be a highly complex disease consisting of a group of heterogeneous disorders with multiple genetic and environmental risk factors.

Thrombophilia due to thrombin defect

A multifactorial disorder of hemostasis characterized by abnormal platelet aggregation in response to various agents and recurrent thrombi formation.

Pregnancy loss, recurrent, 2

A common complication of pregnancy, resulting in spontaneous abortion before the fetus has reached viability. The term includes all miscarriages from the time of conception until 24 weeks of gestation. Recurrent pregnancy loss is defined as 3 or more consecutive spontaneous abortions.
