One of my very favorite aspects of being a scientist is being right on the cutting edge of modern research. I have the pleasure of working in an environment where new discoveries are made daily that span from the mundane to the revelatory. Today I want to take the time to write about a recent paper that for me came to my attention that falls solidly in the revelatory category.

 

 

This 2012 Nature paper by Balazs et al is a great example of modern virology in combination with immunology is being used in novel ways to combat different health issues. Read on to see how this group used a viral vector to give mice protective immunity against HIV infection. Continue reading Designer immunity, vectored immunoprophylaxis and the future of medicine

In through the backdoor: How controlled viral replication can be immunologically advantageous

It may surprise many of you to know that some vaccines currently being used are actually composed of a living virus that actively replicates in your body in order to generate immunity. I’ve written about one of these live vaccines before on this site: the oral polio vaccine (OPV). These are effective vaccines that mount a long-term adaptive immunity to the pathogen in question.  This is done by immune cells that break down the virus and present small parts known as antigens to immature immune cells, which then mature in response to the antigen and are then capable of mounting an immune response to this same challenge in the future.

A recent paper to come out has shown one way that these live but attenuated viruses can be capable of generating such an effective immune response in vivo. Read on to see a potentially novel mechanism in generating an adaptive immune response to cytopathic viruses.
