Abstract: The disclosure relates to an in vitro technology of detecting presence of a plaque particle, isolating the plaque particle followed by its composition analysis in several diseases states or before the disease sets in. A mechanism and a process leading to plaque formation, identifying a component in the mechanism of plaque formation, an identification of a biomarker for diagnosis/early diagnosis of plaque associated disease is described. A method of screening a candidate agent as an anti-plaque agent using flow cytometer, mass spectrometer and specific biomarkers is performed. Provided also are kits for use in practicing embodiment of the methods. A plaqueproteome database is also generated with novel protein sequences for diagnosis and specific antibodies for specific proteins are also disclosed.

Abstract: A novel non-enzymatic assay for lipid modulating drugs is being described for biological samples. For the first time non-enzymatic mechanism of statin drugs in modulating lipid aggregates and forming lipid particles is being shown. A simple flow cytometer based testing for detection of lipid particles, the effect of lipid modulating drug such as statin in vitro and testing for efficacy of the drug for an individual, dosage adjustment and drug discovery mechanism is being described. The lipid modulating drugs either individually or in combination can be discovered, optimized or efficacy tested using this assay. A novel statin induced lipid particle formation described can be used for diagnosis, personalized medicine and biomarker identification as well.

Abstract: Provided herein are methods and compositions for the in vitro formation of multi subunit biological platforms. The biological platforms may be used to screen chemical or biological compounds, in particular compounds that may disrupt or otherwise affect the formation of the multi subunit complexes, or disrupt already-formed in vitro assembled multi subunit complexes. Also provided herein are methods and compositions for the in vivo formation of multi-subunit biological complexes. The methods and compositions described herein may be used to develop animal models of diseases or disorders.

Abstract: Provided herein are methods and compositions for the in vitro formation of an array of plaque particles for use in biological assays, diagnosis, drug discovery and drug development. More specifically, the embodiments described herein relate to the in vitro synthesis of plaque particles when treated with biofluids and identification of such plaque particles by a variety of detection systems. In particular, the resulting in vitro plaque particles resemble atherosclerotic and amyloid plaques. The plaque embodiments described may be used to enable rapid, sensitive and/or efficient drug discovery, medical diagnostics and patient stratification.
