    Moreover, ginseng intake decreased the level of renal oxidized glutathione.Nevertheless, there are many limitations of this study, which should be considered in interpretation of these overall eects.Therefore, more indepth studies are needed to better understand how ginseng intake regulates blood vessel health and renal oxidative stress, and the relationship between ginsengaected steroid hormones and physiological changes in healthy animal models and humans.In addition, further investigation on the bioactive compounds of ginseng will be needed.Overall, our ndings suggest that ginseng intake can improve blood vessel health via modulation of vasodilation, oxidation stress, and proinammatory cytokines.Moreover, the decrease in renal oxidized glutathione indicated that ginseng intake is positively related to the reduction in oxidative stressinduced renal dysfunction.This article is an open access article distributed under the terms and conditions of the Creative Commons Attribution. Successful delivery of this intact transmembrane protein to the target site is quite intriguing.Amidst numerous nanocarriers, a novel class of new generation macrophage membranecoated nanocarriers is endowed with innate tumor homing abilities and inherent capacity of escaping bodys defense machinery.In this perspective, a novel therapeutic module has been fabricated by coating a nontoxic, biodegradable chitosan nanoparticle core with engineered macrophage membranetethered TNF.Herein, the expression of membranebound TNF was induced by challenging Targetmol’s Saxagliptin phorbol myristate acetatedierentiated THP cells with bacterial lipopolysaccharide.Additionally, evaluation of expression of several interleukins after treatment demonstrated excellent biocompatibility of the membranecoated nanoparticles.Proteins, either in secreted or in membranebound forms, interact with their respective receptors, which modulates intricate signaling networks to maintain balance in the overall behavior of the cells.Highly regulated signaling pathways by the proteins replace dead cells with new healthy cells.In case of cell deathrelated pathways, death signals like TNF, CDL, and TRAIL are important.Binding of these proteins on their corresponding receptors initiates the deathsignaling cascade, which results in cell apoptosis.Recently, the role of the transmembrane proteins in apoptosis has been widely studied.Among the signaling molecules, transmembrane tumor necrosis factor alpha has gained much interest in recent years because of its characteristic cell killing ability after binding to its receptor.However, such recombinant proteins are unstable with short halflife and are susceptible to disintegration.Therefore, in order to unleash the true potential of the biological macromolecule, there should be a judicious combination of the therapeutic moiety and a proper de livery veh icle. This imperative need has motivated researchers to develop nanobased delivery systems.A diverse array of nanoparticles ranging from metallic, semimetallic to polymeric particles has emerged.Amongst these, biodegradable polymeric nanoparticles are the most promising class for delivering biological molecules and drugs.These polymeric nanoparticles are armed with multitude of advantages such as, enhanced stability, higher drug payload, tunable physicochemical properties, homogeneous particle distribution, and controlled drug release.However, use of bare nanoparticles often leads to rapid clearance from blood stream because of opsonization.Coating nanoparticles with layers of hydrophilic poly has been established to deceive the body immune system.Hence, a new generation of novel biomimetics could be an alternative to cloak the synthetic nanocarriers by coating with natural membranes.Among them, macrophages could easily produce TNF upon induction with lipopolysaccharide.
