Cellular cholesterol efflux mediated by HDL isolated from subjects with low HDL levels and coronary artery disease

Abstract: Because the HDL fraction of CAD patients with low HDL-C have normal ability to extract cholesterol from cells of the vessel wall, it is suggested that low HDL-C atherogenicity should be ascribed to diminished concentrations of HDL particles rather than to the qualitative properties of the HDL fraction.

“…The LDL-C and HDL-C fractions in liver tissue were extracted by sequential ultracentrifugation as previously described by Nishi et al , 26 and Uint et al 27 The LDL particles were isolated immediately after centrifugation by dialysis at 4 °C against PBS buffer containing 0.25 mM EDTA and then used to quantify LDL cholesterol. HDL was separated from LDL by chemical precipitation after the removal of VLDL, and used to calculate HDL cholesterol.…”

“…Estudos recentes têm enfatizado aspectos não ligados simplesmente à concentração plasmática das lipoproteínas. No que diz respeito a HDL, análises qualitativas da lipoproteína, como capacidade de causar efluxo de colesterol, propriedades anti-oxidantes e anti-inflamatórias vêem sendo estudadas (LAMARCHE et al, 1999;LIRA et al, 2000;ASZTALOS et al, 2000;SVIRIDOV et al, 2002;UINT et al, 2003;KONTUSH, CHAPMAN, 2006 -AMPLIS, 1981;SINGHAD et al, 1983;SPADY et al, 1986;BERRY-LORTSCH;NISTOR et al, 1987;JACKSON et al, 1989;ONTKO et al, 1990;KOWALA et al, 1991;BISHOP, 1992;GROOT et al, 1992;GOULINET, 1993;TSUTSUMI et al, 2001) Tendo em vista que o hábito alimentar e os esforços para controlar os fatores envolvidos no desenvolvimento de aterosclerose ou DAC podem resultar em prevenção e melhora na qualidade de vida, o estudo do circuito do transporte reverso do colesterol após suplementação dietética com diferentes AG pode ser de grande valia.…”

“…Neste contexto, têm sido muitos os esforços destinados a metodologias capazes de aumentar as concentrações plasmáticas de HDLcolesterol (HDL-C). A CETP contribui para o metabolismo das lipoproteínas e particularmente parece estar envolvida com a concentração de HDL-C (KOTAKE et al, 2002;NICHOLLS et al, 2007 (LAMARCHE et al, 1999;LIRA et al, 2000;ASZTALOS et al, 2000;SVIRIDOV et al, 2002;UINT et al, 2003;KONTUSH;CHAPMAN, 2006 (SEYDELL, 2007;AZEVEDO, 2007;DAMINELLI et al, 2008;STRUNZ et al, 2008;MANIERO, 2009;FEITOSA-FILHO et al, 2009;GIRIBELA et al, 2009LO PRETE et al, 2009;ROCHA et al, 2009 (SINGHAD et al, 1983;SPADY et al, 1983;SPADY et al, 1986;BERRY-LORTSCH, SABLE-AMPLIS, 1981;GROOT et al, 1992;GOULINET, 1993;TSUTSUMI et al, 2001), e por ser um modelo animal nos permite avaliar e elucidar de forma mais completa e controlada as possíveis alterações no metabolismo da HDL. A concentração de EC foi obtida pela diferença entre a concentração de HDL-C e de CL da fração HDL.…”
