Chitosan-Based Nanoparticles Against Viral Infections

Vaccination against Mosquito Borne Viral Infections: Current Status

Mosquito borne infectious diseases are among important group of diseases worldwide. Vaccination is available for some tropical mosquito-borne diseases, especially for Japa-nese encephalitis virus infection and yellow fever. There are also several attempts to develop new vaccines for the other mosquito-borne diseases such as malaria, dengue infection and West Nile virus infection. In this articl...

Chitosan-based Nanoparticles in Mucosal Vaccine Delivery

Most infectious diseases are caused by pathogenic infiltrations from the mucosal tract. Nowadays, the use of vaccines has been widely investigated for the prevention of different infectious diseases, infertility, immune disorders, malignancies, and allergies. Broad-spectrum adjuvant substances have been studied for immune system stimulation with a greater efficiency against specific antigens. V...

Lipid Nanoparticles as Carriers for RNAi against Viral Infections: Current Status and Future Perspectives

The efforts made to develop RNAi-based therapies have led to productive research in the field of infections in humans, such as hepatitis C virus (HCV), hepatitis B virus (HBV), human immunodeficiency virus (HIV), human cytomegalovirus (HCMV), herpetic keratitis, human papillomavirus, or influenza virus. Naked RNAi molecules are rapidly digested by nucleases in the serum, and due to their negati...

Chitosan nanoparticles as non-viral gene delivery vehicles based on atomic force microscopy study.

Chitosan (CS), a biocompatible and biodegradable material, can act as a non-viral delivery vehicle with low toxicity. In this study, plasmid DNA (pDNA) and siRNA were encapsulated in CS nanoparticles (NPs) to prepare CS-DNA and CS-siRNA NPs using a complex coacervation process. The CS-DNA particle size was within the range of 180-370 nm with a surface charge ranging from 0 to 18 mV at pH 5.5. T...
