Hydrophobic Inflammatory cells

Substrate hydrophilicity is required for the adhesion of certain biomaterials, such as living tissues. This property has an important role for human body implants, such as orthopedic prostheses. A typical case in which substrate hydrophobicity is required relates to an ophthalmologic scenario, when the surfaces of an intraocular polymer lens should preferably not adhere to proteins in order to avoid the formation of inflammatory cells. 

In bile-duct epithelial cells, the anti-apoptotic protein Mcl-l is strongly expressed in the pre-neoplastic bile-duct inflammatory disease, primary sclerosing cholangitis." This condition appears to involve intra-cellular accumulation of hydrophobic bile acids. 

Flavones consist chiefly of glycosides of luteolin, chrysin, and apigenin. They are less common in fruits [8]. Polymethoxylated flavones, the most hydrophobic flavonoids, present in citrus fruits (mainly in the peel, the nonedible part of the fruit) are tangeretin and nobiletin. Apigenin and chrysin possess anti-inflammatory and free-radical scavenging properties in several cancer cell lines and inhibit tumor cell invasion, metastasis, and mitogen-activated protein kinases (MAPK) and their downstream oncogenes [26]. 

Morisaku et al. support this h3 othesis. The phosphoiylcholine groups were found to possess a hydrophobic hydration layer that did not disturb the hydrogen bonding between the water molecules. PMB-30 is a promising polymer for use in the modification of a wide variety of substrates, providing a stable polymer layer that is resistant to protein adsorption and cell/bacteria adhesion, and can initiate an anti-inflammatory response. The polymer has been filed in the Master Access File of the FDA, USA ( MAF2103, 2012) as LIPIDURE-CM5206, NOF Co., Japan.
