Nova terapia promissora no controlo a longo prazo do HIV

«A new study of the effects of a new antibody treatment suggests it may offer a long-term solution for the control of HIV.
The results of the trial suggest that the antibody therapy not only exerts pressure on blood levels of the virus and stops it infecting new immune cells, but it may also shorten the survival of infected cells.
There is no doubt that antiretroviral therapy (ART) for HIV has transformed what used to be a death sentence into a chronic condition, allowing infected people to live decades longer.
But ART has its drawbacks, not only in terms of physical side effects such as decreased bone density and kidney problems, but also in that stopping treatment or just missing a few doses causes the virus to resurge.
The new study, published in the journal Science, concerns a different and potentially superior approach, in the form of a lasting immunotherapy that triggers an infected person's immune system to make antibodies against HIV and clear it from the body.
Dr. Till Schoofs, one of the study's first authors, and a researcher in molecular immunology at Rockefeller University in New York, NY, says:
"This study provides evidence that a single dose of an antibody stimulates patients' immune response, enabling them to make new or better antibodies against the virus."
Last year, the team reported that the same treatment, based on a molecule called 3BNC117, can greatly reduce the amount of virus present in a patient's blood.»

Comentário do Bloguista: Este estudo vem promover desenvolvimento de estratégias terapêuticas cada vez mais eficazes no tratamento de um vírus tão bem conhecido relativamente ao seu impacto na saúde mundial. Com recurso à imunoterapia, estabelece-se a possibilidade da promoção de um efeito anti-viral cada vez mais potente, exercendo também um efeito na diminuição da sobrevivência das células infetadas.
The creation of this blog came from a challenge posed to Masters students of Biomedical Sciences of the University of Beira Interior, Covilhã (Portugal), by Professor Doctor José Eduardo Cavaco within the course "Project in Biomedical Sciences''. The Biomedical Sciences combine the areas of Biology, Biochemistry, Physics, Management and Engineering, stimulating the capacity for self learning, critical thinking and adaptation to new technologies. Thus, the Biomedics integration in different areas of the national and international job market is possible as technical supporters in clinical environment, consulting, industry, education and research.
