Spanish researchers from the IrsiCaixa AIDS Research Institute have discovered the molecule responsible for the entry of the HIV virus into dendritic cells, belonging to the immune system, which contribute to the spread of the virus in the body. The finding, published in PLoS Biology, opens the door to a new family of drugs against AIDS, capable of blocking this molecule and thus avoiding the resistance to therapy that current treatments entail.
According to the 2012 Global Security Report, prepared by Trustwave, the time when the highest amount of malicious mail is received is between 8 and 9 in the morning. This is the conclusion they have reached after observing the correlation between time slots and the sending of computer viruses.
A small protein inhibits the hepatitis C virus and prevents it from reproducing within infected cells. This molecule could be a good candidate to improve conventional treatments against the disease in patients who have become resistant to them. The work is published in the journal Hepatology and has proven the efficacy of the peptide in cellular tissues.
The AIDS virus has been filmed for the first time infecting the body. The recording shows how the human immunodeficiency virus (HIV) penetrates into immune cells that become a kind of "Trojan horse" and allow the infection to proliferate rapidly. The knowledge of this pathway of entry of the pathogen is key for the development of new treatments to combat the disease.
A team of scientists has designed a vaccine against Ebola that achieves 80 percent protection in mice exposed to the virus. The results of this trial have been published in the US journal Proceedings of the National Academy of Sciences and open the door to the development of a vaccine that can be used in humans.
Richard Larson and Stan Finkelstein, engineers at the Massachusetts Institute of Technology (MIT), have investigated for five years what non-pharmacological measures can minimize the spread of the flu. And they have come to the conclusion that we can prevent the people we live with from transmitting the virus to us by applying five basic measures.
On the coast of Las Cruces, in Chile, scientists have found the largest virus discovered so far. It is called 'Megavirus chilensis' and measures around 0.7 microns in diameter, which implies that it is 10 to 20 times larger than the average virus, and larger than some bacteria.
A phase I clinical trial reveals the immune efficacy of the Spanish candidate MVA-B as a preventive vaccine against the human immunodeficiency virus (HIV). 90% of the volunteers subjected to the compound, elaborated and patented by the Higher Council for Scientific Research (CSIC), have developed an immune response to the virus and 85% of them have maintained it for at least one year. Its safety and efficacy are described in two articles in the Vaccine and Journal of Virology magazines.
Danni Büchner is invited to Sam Dylan's Halloween party. But the "Goodbye Germany" emigrant has no desire for many other party guests. And find clear words.
