> {"body": "Trichomonosis caused by the flagellate protozoan Trichomonas
> vaginalis represents the most prevalent nonviral sexually transmitted disease
> worldwide (WHO-DRHR 2012). In women, the symptoms are cyclic and often worsen
> around the menstruation period. In men, trichomonosis is largely asymptomatic
> and these men are considered to be carriers of T. vaginalis (Petrin et al.
> 1998). This infection has been associated with birth outcomes (Klebanoff et
> al. 2001), infertility (Grodstein et al. 1993), cervical and prostate cancer
> (Viikki et al. 2000, Sutcliffe et al. 2012) and pelvic inflammatory disease
> (Cherpes et al. 2006). Importantly, T. vaginalis is a co-factor in human
> immunodeficiency virus transmission and acquisition (Sorvillo et al. 2001,
> Van Der Pol et al. 2008). Therefore, it is important to study the
> host-parasite relationship to understand T. vaginalis infection and
> pathogenesis. Colonisation of the mucosa by T. vaginalis is a complex
> multi-step process that involves distinct mechanisms (Alderete et al. 2004).
> The parasite interacts with mucin (Lehker & Sweeney 1999), adheres to vaginal
> epithelial cells (VECs) in a process mediated by adhesion proteins (AP120,
> AP65, AP51, AP33 and AP23) and undergoes dramatic morphological changes from
> a pyriform to an amoeboid form (Engbring & Alderete 1998, Kucknoor et al.
> 2005, Moreno-Brito et al. 2005). After adhesion to VECs, the synthesis and
> gene expression of adhesins are increased (Kucknoor et al. 2005). These
> mechanisms must be tightly regulated and iron plays a pivotal role in this
> regulation. Iron is an essential element for all living organisms, from the
> most primitive to the most complex, as a component of haeme, iron-sulphur
> clusters and a variety of proteins. Iron is known to contribute to biological
> functions such as DNA and RNA synthesis, oxygen transport and metabolic
> reactions. T. vaginalis has developed multiple iron uptake systems such as
> receptors for hololactoferrin, haemoglobin (HB), haemin (HM) and haeme
> binding as well as adhesins to erythrocytes and epithelial cells
> (Moreno-Brito et al. 2005, Ardalan et al. 2009). Iron plays a crucial role in
> the pathogenesis of trichomonosis by increasing cytoadherence and modulating
> resistance to complement lyses, ligation to the extracellular matrix and the
> expression of proteases (Figueroa-Angulo et al. 2012). In agreement with this
> role, the symptoms of trichomonosis worsen after menstruation. In addition,
> iron also influences nucleotide hydrolysis in T. vaginalis (Tasca et al.
> 2005, de Jesus et al. 2006). The extracellular concentrations of ATP and
> adenosine can markedly increase under several conditions such as inflammation
> and hypoxia as well as in the presence of pathogens (Robson et al. 2006,
> Sansom 2012). In the extracellular medium, these nucleotides can act as
> immunomodulators by triggering immunological effects. Extracellular ATP acts
> as a proinflammatory immune-mediator by triggering multiple immunological
> effects on cell types such as neutrophils, macrophages, dendritic cells and
> lymphocytes (Bours et al. 2006). In this sense, ATP and adenosine
> concentrations in the extracellular compartment are controlled by
> ectoenzymes, including those of the nucleoside triphosphate
> diphosphohydrolase (NTPDase) (EC: 3.1.4.1) family, which hydrolyze tri and
> diphosphates and ecto-5’-nucleotidase (EC: 3.1.3.5), which hydrolyses
> monophosphates (Zimmermann 2001). Considering that de novo nucleotide
> synthesis is absent in T. vaginalis (Heyworth et al. 1982, 1984), this enzyme
> cascade is important as a source of the precursor adenosine for purine
> synthesis in the parasite (Munagala & Wang 2003). Extracellular nucleotide
> metabolism has been characterised in several parasite species such as
> Toxoplasma gondii, Schistosoma mansoni, Leishmania spp, Trypanosoma cruzi,
> Acanthamoeba, Entamoeba histolytica, Giardia lamblia and fungi, Saccharomyces
> cerevisiae, Cryptococcus neoformans, Candida parapsilosis and Candida
> albicans (Sansom 2012). In T. vaginalis , NTPDase and ecto-5’-nucleotidase
> activities have been characterised and they are involved in host-parasite
> interactions by controlling ATP and adenosine levels (Matos et al. 2001, d,
> de Jesus et al. 2002, Tasca et al. 2003). Considering that (i) iron plays a
> crucial role in the pathogenesis of trichomonosis, (ii) ATP exerts a
> proinflammatory effect in inflammation, (iii) adenosine is important to T.
> vaginalis growth and acts as an antiinflammatory factor (Frasson et al. 2012)
> and (iv) ectonucleotidases modulate the nucleotide levels at infection sites
> (such as those observed in trichomonosis), the aim of this study was to
> investigate the effect of iron on the extracellular nucleotide hydrolysis and
> gene expression of T . vaginalis."}
