Increased levels of reactive oxygen species (ROS) by hyperglycemia can induce apoptosis of renal cells and diabetic nephropathy. The redox balance in the renal cell seems, therefore, of the utmost importance. ROS-mediated apoptosis may be further aggravated by an inadequate cytoprotective response a
INTRODUCTION: Glomerulonephritis is a major cause of morbidity and mortality in patients with systemic lupus erythematosus (SLE). Deposition of autoantibodies in the glomeruli plays a key role in the development of lupus nephritis (LN). Different groups have proposed that either anti-nucleosome anti
Atypical hemolytic uremic syndrome (aHUS) is a thrombotic microangiopathy associated with mutations in complement proteins, most frequently in the main plasma alternative pathway regulator factor H (FH). The hotspot for the FH mutations is in domains 19-20 (FH19-20) that are indispensable for FH act
The cell surface heparan sulfate proteoglycan syndecan-1 (CD138) modulates the activity of chemokines, cytokines, integrins, and other adhesion molecules which play important roles in the regulation of inflammation. We have previously shown that syndecan-1-deficient murine leukocytes display increas
BACKGROUND: Inhibition of the renin-angiotensin-aldosterone system (RAAS) provides renoprotection in adriamycin nephropathy (AN), along with a decrease in overexpression of glomerular heparanase. Angiotensin II (AngII) and reactive oxygen species (ROS) are known to regulate heparanase expression in
Heparinoids are used in the clinic as anticoagulants. A specific pentasaccharide in heparinoids activates antithrombin III, resulting in inactivation of factor Xa and-when additional saccharides are present-inactivation of factor IIa. Structural and functional analysis of the heterogeneous heparinoi
BACKGROUND Sperm heterogeneity in the human, as observed in oligo-astheno-teratozoospermia (OAT), is associated with hypospermatogenesis. METHODS The chromatin of sperm from OAT and normospermic males was characterized with antibodies specific for nucleosomes, the histone H3.1/H3.2 isoform, histone
Systemic lupus erythematosus (SLE) is a prototype inflammatory autoimmune disease resulting from autoimmune responses against nuclear autoantigens. During apoptosis many lupus autoantigens congregate inside the cells and are susceptible to modifications. Modified nuclear constituents are considered
