Abstract
Dramatic developments in vaccinology and immunology over the last decade have led to the identification of novel antigens, adjuvants and delivery systems, and combinations thereof, that may prove to be highly efficacious vaccines. Despite this explosion in technological developments, in reality, very few novel vaccines for human use have reached the market. Liposomes are one of the most intensively studied areas of vaccine and delivery system research. Several intrinsic features of liposomes lend themselves to their use in vaccines, particularly in terms of safety, versatility and adjuvant properties. Modifications to liposomal structures in terms of additional adjuvants are also playing a role in potential medical applications. The most significant progress to date has been made with virosomes, a novel antigen delivery system that incorporates the haemagglutinin from influenza virus into liposomes and can induce both humoral- and cell-mediated immunity to antigens. This review discusses the presentation and processing of antigens delivered by virosomes, in light of both licensed vaccines and potential vaccine candidates.

Advances of natural products, bio-actives and novel drug delivery system against emerging viral infections
Due to the increasing prevalence of viral infections and the ability of these human pathogens to develop resistance to current treatment strategies, there is a great need to find and develop new compounds to combat them. These molecules must have low toxicity, specific activity and high bioavailability. The most suitable ...read more
Electrospun Fibers as Drug Delivery Systems
In recent years, electrospun fibers have attracted considerable attention as potential platforms for drug delivery due to their distinctive properties and adaptability. These fibers feature a notable surface area-to-volume ratio and can be intentionally designed with high porosity, facilitating an increased capacity for drug loading and rendering them suitable for ...read more
Emerging Nanotherapeutics for Mitigation of Neurodegenerative Disorders
Conditions affecting the central nervous system (CNS) present a significant hurdle due to limited access of both treatments and diagnostic tools for the brain. The blood-brain barrier (BBB) acts as a barrier, restricting the passage of molecules from the bloodstream into the brain. The most formidable challenge facing scientists is ...read more
Nanotechnology Based Chemotherapy for the treatment of Head & Neck Cancer
The escalating recurrence rates observed in Head and Neck cancer, particularly within the chemo-therapeutically treated cohort (50-60%), can be attributed to the non-selective nature of current anticancer drug delivery modalities. In this context, nanotechnology-based drug delivery systems emerge as a promising avenue for achieving precise localization of therapeutic agents to ...read more
