FXYD proteins are a family of seven small regulatory proteins, expressed in a tissue-specific manner, that associate with Na,K-ATPase as subsidiary subunits and modulate kinetic properties. This study describes an additional property of FXYD proteins as stabilizers of Na,K-ATPase. FXYD1 (phospholemman), FXYD2 (γ subunit), and FXYD4 (CHIF) have been(More)
Edible vaccines offer exciting possibilities for significantly reducing the burden of diseases like hepatitis and diarrhoea, particularly in developing world where storing and administering vaccines are the major problems. Edible vaccines are prepared by molecular farming using the science of genetic engineering. Selected genes are introduced into the(More)
This work investigates the preparation and in vivo efficacy of plasmid DNA loaded chitosan nanoparticles for nasal mucosal immunization against hepatitis B. Chitosan pDNA nanoparticles were prepared using a complex coacervation process. Prepared nanoparticles were characterized for size, shape, surface charge, plasmid loading and ability of nanoparticles to(More)
In this study, hepatitis B surface antigen (HBsAg) loaded poly(lactic-co-glycolic acid) (PLGA) microparticles were prepared and coated with chitosan and trimethyl chitosan (TMC) to evaluate the effect of coating material for nasal vaccine delivery. The developed formulations were characterized for size, zeta potential, entrapment efficiency, and mucin(More)
Solid lipid nanoparticles (SLNs) are essentially composed of triglyceride(s) that orient to form a polar core with polar heads oriented toward the aqueous phase, resembling chylomicrons. The composition of such SLNs may alter the course of drug absorption predominantly to and through lymphatic route and regions, presumably following a transcellular path of(More)
The transcytotic capability and expression of distinct carbohydrate receptors on the intestinal M-cells render it a potential portal for the targeted oral vaccine delivery. PLGA nanoparticles loaded with HBsAg were developed and antigen was stabilized by co-encapsulation of trehalose and Mg(OH)(2). Additionally, Ulex europaeus 1 (UEA-1) lectin was anchored(More)
Osmolytes produced under stress in animal and plant systems have been shown to increase thermal stability of the native state of a number of proteins as well as induce the formation of molten globule (MG) in acid denatured states and compact conformations in natively unfolded proteins. However, it is not clear whether these solutes stabilize native state(More)
PLA/PLGA nanoparticles are well known as efficient vaccine delivery systems, but they have got limitation in oral vaccine delivery because of their sensitivity to harsh gastric environment. The aim of present study was to improve the stability of PLA nanoparticles in such environment by copolymerizing PLA with PEG. Nanoparticles were formulated using(More)
Bacillus anthracis genome harbors a toxin-antitoxin (TA) module encoding pemI (antitoxin) and pemK (toxin). This study describes the rPemK as a potent ribonuclease with a preference for pyrimidines (C/U), which is consistent with our previous study that demonstrated it as a translational attenuator. The in silico structural modeling of the PemK in(More)
We are reporting highly economical plant based method for the production of luminescent water soluble carbon dots (C-dot) using Indian water plant Trapa bispinosa peel extract without adding any external oxidizing agent at 90 °C. C-dots ranging from 5 to 10nm were found in the solution with a prominent green fluorescence under UV-light (λex=365 nm). UV-vis(More)
