Human immunodeficiency virus (HIV)-1 is mainly transmitted mucosally during sexual intercourse. We therefore evaluated the protective efficacy of a vaccine active at mucosal sites. Macaca mulatta monkeys were immunized via both the intramuscular and intranasal routes with an HIV-1 vaccine made of gp41-subunit antigens grafted on virosomes, a safe delivery carrier approved in humans with self-ad...
Recombination between co-infecting poxviruses provides an important mechanism for generating the genetic diversity that underpins evolution. However, poxviruses replicate in membrane-bound cytoplasmic structures known as factories or virosomes. These are enclosed structures that could impede DNA mixing between co-infecting viruses, and mixing would seem to be essential for this process. We hypo...
The transdermal drug delivery system is an alternative method of administration drugs. Most the drugs are delivered by conventional oral, topical, intravenous, and intramuscular methods limited efficiency. However, now clinical use because stratum cornea skin act as effective barrier that limits permeation through skin. To overcome this disadvantage, there Recent developments in delivery, such ...
This paper reports the data concerning the net economic cost savings attributable to influenza vaccination in healthy children aged 2-5 years, and may be useful when deciding the best recommendations for the use of influenza vaccine in pediatrics. A total of 303 previously unprimed healthy children aged 2-5 years (163 males; mean age+/-S.D.: 3.22+/-2.43 years) were prospectively, blindly random...
Vaccinia virus replication is inhibited by etoposide and mitoxantrone even though poxviruses do not encode the type II topoisomerases that are the specific targets of these drugs. Furthermore, one can isolate drug-resistant virus carrying mutations in the viral DNA ligase and yet the ligase is not known to exhibit sensitivity to these drugs. A yeast two-hybrid screen was used to search for prot...
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...
