In this study, we show that membranes containing phosphatidylserine (PS), a negatively charged phospholipid, induce a rapid formation of fibers by a variety of proteins, viz., lysozyme, insulin, glyceraldehyde-3-phosphate dehydrogenase, myoglobin, transthyretin, cytochrome c, histone H1, and alpha-lactalbumin. Congo red staining of these fibers yields the characteristic light green birefringence of amyloid, and fluorescent lipid tracers further reveal them to include phospholipids. Our results suggest that PS as well as other acidic phospholipids could provide the physiological low-pH environment on cellular membranes, enhancing protein fibril formation in vivo. Interestingly, all the proteins mentioned above either are cytotoxic or induce apoptosis. PS-protein interaction could be involved in the mechanism of cytotoxicity of the aggregated protein fibrils, perturbing membrane functions. Importantly, our results suggest that this process induced by acidic phospholipids may provide an unprecedented and generic connection between three current major areas of research: (i) mechanism(s) triggering amyloid formation, (ii) cytotoxicity of amyloidal protein aggregates, and (iii) mechanism(s) of action of cytotoxic proteins.

Maybe our new part time CEO can call his contacts to find out how valuable PS Targeting is....maybe Johnny Stafford can be conferenced in but I am sure some have been listening to their conversations already

The problem with manipulation....is each time you manipulate ...it's easier to track because statistics and probabilities say it is not possible

MIT researchers with Tom Knight should know that and PS Targeting mapped to protein Biomarkers are priority
