Correlation between the degree of immune activation, production of IL-2 and FOXP3 expression in CD4+CD25+ T regulatory cells in HIV-1 infected persons under HAART.

Chronic immune activation is the leading event in the pathogenesis of HIV-1 infection and is associated with depletion of CD4+ T cells and Th1/Th2 imbalance. The role of Tregs in HIV infection is still controversial as these cells may control both immune activation and HIV-specific T cell responses. Aim of the present study was to correlate the degree of immune activation with FOXP3 expression and production of IL-2 and IL-10.

A comparative analysis of the effects of in-vivo and in-vitro abscisic-acid treatment on the surface electrical properties of barley chloroplast membranes.

The effects of in-vivo and in-vitro abscisic acid (ABA) treatments on the surface charge density (σ) of barley (Hordeum vulgare L.) thylakoids were compared using 9-aminoacridine fluorescence. The estimated surface charge density of isolated thylakoid membranes from control (non-treated) barley leaves was-0.
