Cardiolipin (1) is a dimeric phospholipid found in the mitochondrial membranes of both plants and animals. In order to understand better its role, we report the preparation of an immobilised analogue (2) using phosphoramidite chemistry; the probe has been used successfully to bind a recombinant protein containing a cardiolipin-binding domain.

The present report illustrates the response to osmotic stress of an extreme halophilic archaeon, Halorubrum sp., isolated from the saltern ponds of Margherita di Savoia in southern Italy. The hypotonic stress induces relevant changes in the membrane lipid composition: archaeal cardiolipin content markedly increases, whereas phosphatidylglycerol (PG) decreases. Membranes isolated from this archa...

The magnesium transporter A (MgtA) is a specialized P-type ATPase, believed to import Mg(2+) into the cytoplasm. In Salmonella typhimurium and Escherichia coli, the virulence determining two-component system PhoQ/PhoP regulates the transcription of mgtA gene by sensing Mg(2+) concentrations in the periplasm. However, the factors that affect MgtA function are not known. This study demonstrates, ...

Certain surface active substances produce a non-syphilitic flocculation reaction if cardiolipin is replaced by them in the VDRL test system (Tuomioja 2nd Kajanne, 1956). The test was called the APC test because these surface active substances were products of the Atlas Powder Company (Wilmington, Delaware). The most active was Span 60, stated by the manufacturer to be mainly sorbitan monosteara...

Anti-phospholipid syndrome (APS) is a potentially life-threatening autoimmune condition characterized by the presence of anti-phospholipid antibodies (aPL) giving rise to increased hypercoagulability, which induces venous or arterial thrombotic events at whatever age and recurrent fetal loss in the fertile age. Antigens that are targeted by aPL include cardiolipin and beta2-glycoprotein I. Prim...
