The Prion Puzzle

The infectious prion then hijacks the body s machinery, reprogramming it into a willing executioner of prion replication. Since the disease s outbreak, it has been revealed that many common ailments including Alzheimer s disease and Parkinson s disease have similar properties.

Sensitive detection of pathogens, such as HIV, typically relies on the presence of nucleic acids (DNA or RNA), which are absent in prions. Recently, however, effective methods for amplifying prions have been developed, which could enable detection of the pathogen before it can damage its host.

In late 1995, two young people were diagnosed with Creutzfeldt Jakob disease a rare disease typically seen in elderly patients. Post mortem examinations of their brains revealed deposits of prions the infectious agents that cause scrapie, kuru, and mad cow disease.

Introducing an innocuous version of a pathogen into the body causes the immune system to produce antibodies, which will neutralize the wild pathogen if it enters the body later. A decade ago, my laboratory showed that an anti prion antibody could significantly delay and, in some cases, prevent infection in mice that had been exposed to prions.

CJD belongs to the family of what are called prion diseases, a unique group of neurodegenerative diseases that can be transmitted. Although the precise nature of the disease s transmission remains uncertain, a key event in these disorders is the conversion of the prion protein s normal cells to an abnormal form that appears to be the major (if not the sole) component of the infection.

The host s body produces its own version of the prion protein, and it is difficult to create a high quality antibody against a body s own components. As a result, rather than trying to induce immunity, researchers must develop prefabricated anti prion antibodies that can be delivered directly to patients.

The Swiss scientist Charles Weissmann demonstrated this using mice in a series of experiments two decades ago. Using recently developed zinc finger nuclease technology, any given gene can be removed from an animal s DNA.

These animals cannot host infectious prions. While the quality of their meat remains to be assessed, they can provide a safe source of biological agents such as therapeutic antibodies and growth factors for use in human medicine.

The plant was also used, after its acquisition by the biological weapons programme, for research on three viruses camelpox, enterovirus 70 and human rotavirus.

The Nutritional Health Project (PSN) is designed to improve the coverage and quality of health services relating to nutrition and family planning, to strengthen the organization and management of the health sector, and to raise further funding.

And certainly, this was the decade in which we discovered AIDS and the virus that causes it, HIV.

All right, I can see a rhinovirus and here's the blow up of the rhinovirus's little barcode but what about different rhinoviruses?

Variant CJD was first described in 1996, following intensive surveillance activities undertaken by the UK National CJD Surveillance Unit (NCJDSU) in Edinburgh. This new form of prion disease had distinctive clinical and pathological features, and occurred in young patients within a single genetic subgroup.

In fact, this is not unique to HIV. The vast majority of viruses come from animals.

And a pig disease, a pig virus, and a human virus can both proliferate, and because of their kind of reproduction, they can combine and produce a new virus.

The virus that causes AIDS is the trickiest pathogen scientists have ever confronted.
