抗原变异可使得多种致病微生物易于逃避宿主免疫应答。表达在感染红细胞表面的恶性疟原虫红细胞表面蛋白1（PfPMP1）与感染红细胞、内皮细胞、树突状细胞以及胎盘的单个或多个受体作用，在黏附及免疫逃避中起关键的作用。每个单倍体基因组var基因家族编码约60种成员，通过启动转录不同的var基因变异体为抗原变异提供了分子基础。

2013 ACCF/AHA Guideline for the Management of Heart Failure: A Report of the American College of Cardiology Foundation/American Heart Association Task Force on Practice Guidelines

Ventricular fibrillation (VF) is a major cause of death after acute myocardial infarction (MI), accounting for the majority of deaths that occur within an hour after the onset of symptoms (Fulton et al. 1969), Ventricular fibrillation has been estimated to occur in 4 to 18% of patients with acute MI in coronary care units (Pasternak et al. 1992). In an attempt to reduce the complications resulting from VF during acute MI, the use of prophylactic antiarrhythmic drugs has been recommended (Harrison & Berte 1982; Julian et al. 1964; Lown et al. 1967). Lidocaine (lignocaine) has generally been the agent used for this indication, because of its fast onset of action, relatively rapid elimination kinetics, and lack of haemodynamic depressant action (Nattel et al. 1987). However, the results of clinical trials to establish the value of lidocaine prophylaxis in acute MI have been conflicting, leading some physicians to suggest that the uncertain benefits of lidocaine therapy are outweighed by the potential risks (Kertes & Hunt 1984). Recent meta-analyses have suggested that, while lidocaine may reduce the prevalence of VF, the drug does not reduce, and may even increase, mortality in patients with acute MI (Hine et al. 1989; MacMahon et al. 1988). Because of these changing perceptions, we have critically reviewed the evidence available regarding lidocaine prophylaxis in acute MI. The value of any therapy is determined by the balance between its beneficial and harmful actions. In order to judge the benefits of lidocaine prophylaxis against primary VF in acute MI, one must kI'lOw the likelihood of the target arrhythmia, the efficacy of lidocaine in preventing it, and the consequences should the arrhythmia occur. To assess harmful actions, one must appreciate the frequency and severity of the adverse consequences of lidocaine therapy. Controlled clinical trials provide the most direct indication of risk-benefit ratio. On the other hand, the interpretation of such trials may be complicated by their specific design.

42 – The Molecular Pathophysiology of Atrial Fibrillation

Endogenous cardiac pacemaker function regulates the rate and rhythm of cardiac contraction. The mutation p.Lys23Glu in the cohesin protein Shugoshin-1 causes severe heart arrhythmias due to sinoatrial node dysfunction and a debilitating gastrointestinal motility disorder, collectively termed the Chronic Atrial and Intestinal Dysrhythmia Syndrome, linking Shugoshin-1 and pacemaker activity. Hyperpolarization-activated, cyclic nucleotide-gated cation channel 4 (HCN4) is the predominant pacemaker ion-channel in the adult heart and carries the majority of the “funny” current, which strongly contributes to diastolic depolarization in pacemaker cells. Here, we study the mechanism by which Shugoshin-1 affects cardiac pacing activity with two cell models: neonatal rat ventricular myocytes and Chronic Atrial and Intestinal Dysrhythmia Syndrome patient-specific human induced pluripotent stem cell derived cardiomyocytes. We find that Shugoshin-1 interacts directly with HCN4 to promote and stabilize cardiac pacing. This interaction enhances funny-current by optimizing HCN4 cell-surface expression and function. The clinical p.Lys23Glu mutation leads to an impairment in the interaction between Shugoshin-1 and HCN4, along with depressed funny-current and dysrhythmic activity in induced pluripotent stem cell derived cardiomyocytes derived from Chronic Atrial and Intestinal Dysrhythmia Syndrome patients. Our work reveals a critical non-canonical, cohesin-independent role for Shugoshin-1 in maintaining cardiac automaticity and identifies potential therapeutic avenues for cardiac pacemaking disorders, in particular Chronic Atrial and Intestinal Dysrhythmia Syndrome. A mutation in Shugoshin-1 causes the Chronic Atrial and Intestinal Dysrhythmia (CAID) Syndrome, but the underlying mechanisms are unknown. Here, the authors show that Shugoshin-1 controls cardiac pacemaker activity by interacting with HCN4 to enhance its cell-surface expression, and that the CAID-Syndrome mutation disrupts cardiac pacemaking by interfering with this important non-canonical interaction.
