Entamoeba histolytica cell movement: A central role for self-generated chemokines and chemorepellents

Entamoeba histolytica cells, the cause of amoebic dysentery, are highly motile, and this motility is an essential feature of the pathogenesis and morbidity of amoebiasis. However, the control of E. histolytica motility within the gut and during invasion is poorly understood. We have used an improved chemotaxis assay to identify the key extracellular signals mediating Entamoeba chemotaxis. The dominant responses we observe are caused by factors generated by E. histolytica cells themselves. Medium that has been conditioned by E. histolytica growth causes both chemokinesis and negative chemotaxis. The speed of random movement is more than doubled in conditioned compared with fresh medium, and cells move efficiently away from conditioned medium by negative chemotaxis. Ethanol, the product of Entamoeba glucose metabolism, is the principal component of the chemokinetic response. The closely related but nonpathogenic Entamoeba dispar shows no change in motility in response to conditioned medium implying that these responses are central to E. histolytica pathogenesis

Visceral Fibromuscular Dysplasia: from asymptomatic disorder to emergency.

Fibromuscular dysplasia (FMD) is an idiopathic, segmental, non-atherosclerotic and non-inflammatory disease of the musculature of arterial walls, leading to stenosis of small and medium-sized arteries, mostly involving renal and cervical arteries. As a result of better and more systematic screening, it appears that involvement of the splanchnic vascular bed is more frequent than originally assumed. We review epidemiology, pathogenesis, clinical picture as well as diagnosis and treatment of visceral artery (VA) FMD. The clinical picture is very diverse and diagnosis is based on CT-, MR- or conventional catheter-based angiography. Involvement of VAs generally occurs among patients with multi-vessel FMD. Therefore, screening for VA FMD is advised especially in renal artery (RA) FMD and in case of aneurysms and/or dissections. Treatment depends on the clinical picture. However, the level of evidence is low and much of the common practice is extrapolated from visceral atherosclerotic disease. This article is protected by copyright. All rights reserved
