Background and Aims: Influenza is one of the main respiratory infections of humans, responsible for 300,000–500,000 annual deaths world-wide. Vaccination is one of the best ways to prevent infections including influenza. Influenza virosomes are virus-like particles, which retain the cell binding and membrane fusion properties of the native virus, but lack the ribonucleoprotein (RNP). A vi...

Reconstituted influenza virosomes (virus membrane envelopes) have been used previously to deliver pDNA (plasmid DNA) bound to their external surface to a variety of target cells. Although high transfection efficiencies can be obtained with these complexes in vitro, the virosome-associated DNA is readily accessible to nucleases and could therefore be prone to rapid degradation under in vivo cond...

Reconstituted Sendai viral envelopes (virosomes) are well recognized for their promising potential in membrane fusion-mediated delivery of bioactive molecules to liver cells. Despite the known function of viral envelope glycoproteins in catalyzing fusion with cellular membrane, the role of host cell proteins remains elusive. Here, we used two-dimensional differential in-gel electrophoresis to a...

Virosomes are reconstituted viral envelopes that can fill in as vaccines and as vehicles for cell conveyance of different macromolecules. The prospect of drug delivery and targeting systems utilizing virosomes is an intriguing innovative work field. Since virosomes are biocompatible, biodegradable, non-poisonous and nonautoimmunogenuic; endeavors have been made to use them as antibodies or adju...

The respiratory tract with its ease of access, vast surface area and dense network of antigen-presenting cells (APCs) represents an ideal target for immune-modulation. Bio-mimetic nanocarriers such as virosomes may provide immunomodulatory properties to treat diseases such as allergic asthma. In our study we employed a triple co-culture model of epithelial cells, macrophages and dendritic cells...

Background: An increasing number of tumor associated antigens (TAA) capable of inducing immune responses have been identified in the last two decades. Unfortunately, they are weak immunogens and require potent adjuvants to promote their immunogenicity. Virosomes, nano-lipid vesicles containing viral protein spikes, have been proven amenable for transferring antigen (Ag) to the major histocompat...
