The Role of Natriuretic peptides in Renovascular Hypertension and its correlation with the Evolution of Myocardial Hypertrophy

The interactions between pressure and volume overload that occur in hypertension lead to different patterns of cardiac hypertrophy and to increase in natriuretic peptides (NPs). The profiles of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) synthesis and secretion have been investigated in models of hypertension. However, the different evolution of these profiles during the acute and chronic periods of pressure overload-induced cardiac hypertrophy is still unknown. For this reason, we studied one-kidney, one clip model using Sprague-Dawley rats at weeks 2, 4, 6 and 12 and correlated the evolution of these profiles with cardiac hypertrophy and hypertension. We observed a positive correlation between blood pressure elevation and the degree of cardiac hypertrophy, with a time-dependent increase in both parameters from week 2. Levels of BNP expression showed an early increase after 2 weeks of treatment while ANP increased significantly after 6 weeks. Yet, the increase in ANP expression was gradual, allowing its correlation with hypertrophy and hypertension. The NP expression has a differential response in the early stages of the development of hypertrophy induced by the renovascular model, with an early increase in BNP expression. Once hypertrophy develops, BNP expression is no longer specific and the increase of both NPs depends on and correlates with the degree of cardiac hypertrophy.Fil: Cerrudo, Carolina Susana.

The renin angiotensin system in the central nervous system

The first evidences indicating that angiotensin II (ANG II) was a peptide with action on the brain were shown in 1961 when it was found that the intraventricular injection of ANG II induces a centrally mediated pressor response. As a neuropeptide, ANG II belongs to the class of neuromodulators. The brain renin angiotensin system (RAS) exerts paracrine, autocrine and intracrine functions independently of circulating blood-borne ANG II which has a limited access to the brain by the blood-brain barrier (BBB) in the circumventricular organs (CVOs). Brain-generated ANG II controls several physiological processes like stimulation of thirst, water intake and sodium appetite, acting as a neurotransmitter in neurons of brain areas such as the Subfornical organ (SFO) and Organum vasculosum of the lamina terminalis (OVLT). Generated angiotensins (ANGs) at the central nervous system (CNS) also stimulate endocrine secretions like argininevasopressin (AVP), oxytocin (OT), corticotrophin-releasing hormone (CRH) and adenocorticotrophin (ACTH secretion). Brain ANG II modulates the sympathetic autonomic functions and regulates blood pressure by increasing AVP and ACTH secretion and modulating the baroceptor reflex and the sympathetic output. During the last decade it has been established that, apart from its classical actions, ANG II exhibits other effects induced by direct action on its receptors or via local effects of its metabolites . Thereby, central actions of ANGs are not exclusively associated with their traditional roles. Indeed, several studies have shown that central ANGs are also involved in sexual behavior, stress, learning, and memory.Fil: Choi, Marcelo Roberto. Universidad de Buenos Aires.

Natriuretic Peptides Synthesis and Secretion Profiles during the Evolution of Cardiac Hypertrophy in DOCA-Salt Hypertensive Rats

Durante el desarrollo de la hipertensión arterial, las interacciones entre las sobrecargas de presión y de volumen conducen a diferentes patrones de hipertrofia cardíaca y a un aumento de los péptidos natriuréticos (PN). Los perfiles de síntesis y secreción de ANP y BNP se han investigado en modelos de hipertensión arterial; sin embargo, aún no se ha estudiado la evolución diferencial de estos perfiles durante períodos agudos y crónicos de la hipertrofia cardíaca producida por sobrecarga de volumen. Por este motivo estudiamos ratas Sprague- Dawley con el modelo DOCA-sal a las 2, 4, 6 y 12 semanas, correlacionando la evolución de dichos perfiles con la hipertrofia cardíaca y la hipertensión arterial. El grado de hipertrofia cardíaca se correlacionó positivamente con la expresión del ANP en el ventrículo izquierdo y con los niveles de ANP en plasma. La expresión del ANP aumentó a las 4 semanas de tratamiento, mientras que la de BNP se incrementó recién a las 6 semanas. Asimismo, el BNP plasmático se incrementó sólo en el grupo con 12 semanas de tratamiento, mientras que el ANP plasmático mostró un aumento a partir de las 2 semanas de tratamiento. Durante el desarrollo de la hipertrofia cardíaca producida en el modelo DOCA-sal, la síntesis y la secreción de los PN responden en forma diferencial, con incremento precoz del ANP. Además, el aumento de éste superó al de BNP en todos los grupos DOCA-sal, lo que permitiría considerar al ANP como un marcador más específico de la sobrecarga de volumen.The interactions between pressure and volume overload that occur in hypertension lead to different patterns of cardiac hypertrophy and to increase in natriuretic peptides (NPs).

NP secretion has a differential response in the early stages of the development of cardiac hypertrophy induced by the DOCA-salt model, with an early increase in ANP. As ANP levels were exceeded to those of BNP in all the DOCA-salt groups, ANP might be considered a more specific marker of volume overloadFil: Cerrudo, Carolina Susana. Universidad de Buenos Aires.

Immunostimulation by Lactobacillus kefiri S-layer proteins with distinct glycosylation patterns requires different lectin partners

S-layer (glyco)-proteins (SLPs) form a nanostructured envelope that covers the surface of different prokaryotes and show immunomodulatory activity. Previously, we have demonstrated that the S-layer glycoprotein from probiotic Lactobacillus kefiri CIDCA 8348 (SLP-8348) is recognized by Mincle (macrophage inducible C-type lectin receptor) and its adjuvanticity depends on the integrity of its glycans. However, the glycan´s structure has not been described so far. Herein, we analyze the glycosylation pattern of three SLPs, SLP-8348, SLP-8321, and SLP-5818, and explore how these patterns impacts their recognition by Ctype lectin receptors (CLRs) and the immunomodulatory effect of the L. kefiri SLPs on antigen-presenting cells. HPAEC-PAD performed after β-elimination showed glucose as the major component in the O-glycans of the three SLPs, however, some differences in the length of hexose chains were observed. No N-glycosylation signals were detected in SLP-8348 and SLP-8321, but SLP5818 was observed to have two sites carrying complex N-glycans based on a site-specific analysis and a glycomic workflow of the permethylated glycans. SLP-8348 was previously shown to enhance LPS-induced activation on both RAW264.7 macrophages and murine BMDCs; we now show SLP-8321 and SLP-5818 have a similar effect regardless of the differences in their glycosylation patterns. Studies performed with BMDCs from CLR-deficient mice revealed that the immunostimulatory activity of SLP-8321 depends on its recognition by Mincle, whereas SLP-5818’s effects are dependent on SignR3 (murine ortholog of human DC-SIGN). These findings encourage further investigation of both the potential application of these SLPs as new adjuvants and the protein glycosylation mechanisms in these bacteria.Fil: Malamud, Mariano.

Acute sodium overload produces renal tubulointerstitial inflammation in normal rats

The aim of the present study was to determine whether acute sodium overload could trigger an inflammatory reaction in the tubulointerstitial (TI) compartment in normal rats. Four groups of Sprague-Dawley rats received increasing NaCl concentrations by intravenous infusion. Control (C): Na + 0.15M; G1: Na+ 0.5M; G2: Na+ 1.0M; and G3: Na+ 1.5M. Creatinine clearance, mean arterial pressure (MAP), renal blood flow (RBF), and sodium fractional excretion were determined. Transforming growth factor β1 (TGF-β1), α-smooth muscle actin (α-SMA), RANTES, transcription factor nuclear factor-kappa B (NF-κB), and angiotensin II (ANG II) were evaluated in kidneys by immunohistochemistry. Animals with NaCl overload showed normal glomerular function without MAP and RBF modifications and exhibited a concentration-dependent natriuretic response. Plasmatic sodium increased in G2 (P G2>C group. These results suggest that an acute sodium overload is able 'per se' to initiate TI endothelial inflammatory reaction (glomerular and peritubular) and incipient fibrosis in normal rats, independently of hemodynamic modifications. Furthermore, these findings are consistent with the possibility that activation of NF-κB and local ANG II may be involved in the pathway of this inflammatory process.Fil: Roson, Maria Ines.

Cardiac Natriuretic Peptide Profiles in Chronic Hypertension by Single or Sequentially Combined Renovascular and DOCA-Salt Treatments

The involvement of natriuretic peptides was studied during the hypertrophic remodeling transition mediated by sequential exposure to chronic hemodynamic overload. We induced hypertension in rats by pressure (renovascular) or volume overload (DOCA-salt) during 6 and 12 weeks of treatment. We also studied the consecutive combination of both models in inverse sequences: RV 6 weeks/DS 6 weeks and DS 6 weeks/RV 6 weeks. All treated groups developed hypertension. Cardiac hypertrophy and left ventricular ANP gene expression were more pronounced in single DS than in single RV groups. BNP gene expression was positively correlated with left ventricular hypertrophy only in RV groups, while ANP gene expression was positively correlated with left ventricular hypertrophy only in DS groups. Combined models exhibited intermediate values between those of single groups at 6 and 12 weeks. The latter stimulus associated to the second applied overload is less effective than the former to trigger cardiac hypertrophy and to increase ANP and BNP gene expression. In addition, we suggest a correlation of ANP synthesis with volume overload and of BNP synthesis with pressure overload-induced hypertrophy after a prolonged treatment. Volume and pressure overload may be two mechanisms, among others, involved in the differential regulation of ANP and BNP gene expression in hypertrophied left ventricles. Plasma ANP levels reflect a response to plasma volume increase and volume overload, while circulating BNP levels seem to be regulated by cardiac BNP synthesis and ventricular hypertrophy.Fil: Cerrudo, Carolina Susana.

Electrical impedance tomography for non-invasive identification of fatty liver infiltrate in overweight individuals

Non-alcoholic fatty liver disease (NAFLD) is one of the most common causes of cardiometabolic diseases in overweight individuals. While liver biopsy is the current gold standard to diagnose NAFLD and magnetic resonance imaging (MRI) is a non-invasive alternative still under clinical trials, the former is invasive and the latter costly. We demonstrate electrical impedance tomography (EIT) as a portable method for detecting fatty infiltrate. We enrolled 19 overweight subjects to undergo liver MRI scans, followed by EIT measurements. The MRI images provided the a priori knowledge of the liver boundary conditions for EIT reconstruction, and the multi-echo MRI data quantified liver proton-density fat fraction (PDFF%) to validate fat infiltrate. Using the EIT electrode belts, we circumferentially injected pairwise current to the upper abdomen, followed by acquiring the resulting surface-voltage to reconstruct the liver conductivity. Pearson’s correlation analyses compared EIT conductivity or MRI PDFF with body mass index, age, waist circumference, height, and weight variables. We reveal that the correlation between liver EIT conductivity or MRI PDFF with demographics is statistically insignificant, whereas liver EIT conductivity is inversely correlated with MRI PDFF (R = −0.69, p = 0.003, n = 16). As a pilot study, EIT conductivity provides a portable method for operator-independent and cost-effective detection of hepatic steatosis

In depth N-glycoproteomics shows glyco-features of chicken egg white

Chicken egg white proteins have been studied using proteomic approaches. Some glycomic studies of isolated egg white proteins and of the complex egg white have been reported. However, no detailed glycoproteomic studies on the whole egg white have been performed so far to simultaneously characterize the modified peptides along with their glycan moieties. In this study, using a nanoHPLC-ESI-Orbitrap-HCD analysis, glycoproteins from chicken egg white were studied in a single experiment using a three-step workflow. Using this glycoproteomic approach, 19 glycoproteins were characterized. Among them, glycosylation sites and their linked glycan structures in 6 low abundance proteins (heat shock cognate 71 kDa protein, vimentin (fragment), E1BY93 uncharacterized protein, transforming growth factor beta-2 proprotein, ITA6_CHICK integrin alpha-6 and VIT2_CHICK vitellogenin-2) were obtained. Chicken egg white is an easily available source of high quality proteins in the human diet. However, there are reports describing protein-induced allerginicity associated with egg consumption probably due to glycosylated proteins. This new characterization will be useful for the development of appropriate processing methods to decrease the adverse health effects of glycoproteins and expand egg white nutraceutical applications.Fil: Cavallero, Gustavo Javier.
