Nearly half of the world's population is at risk of infection by the dengue virus, yet there is no specific treatment for the disease. Now a therapy to protect people from the virus could finally be a step closer, thanks to a team at MIT. http://medicalxpress.com/news/2013-04-advances-therapy-dengue-virus.html Diseases, Conditions, Syndromes Mon, 08 Apr 2013 16:18:40 EST news284656447 Researchers have learned the precise structure of the mosquito-transmitted chikungunya virus pathogen while it is bound to antibodies, showing how the infection is likely neutralized. http://medicalxpress.com/news/2013-04-reveals-antibodies-neutralize-mosquito-borne-virus.html Medical research Tue, 02 Apr 2013 12:37:59 EST news284125062 (Medical Xpress)—A new study by Los Alamos National Laboratory and University of Pennsylvania scientists defines previously unknown properties of transmitted HIV-1, the virus that causes AIDS. The viruses that successfully pass from a chronically infected person to a new individual are both remarkably resistant to a powerful initial human immune-response mechanism, and they are blanketed in a greater amount of envelope protein that helps them access and enter host cells. http://medicalxpress.com/news/2013-04-deciphers-hiv.html HIV & AIDS Mon, 01 Apr 2013 09:38:43 EST news284027912 Fresh insights into the protective seal that surrounds the DNA of our cells could help develop treatments for inherited muscle, brain, bone and skin disorders. http://medicalxpress.com/news/2013-02-cell-discovery-key-inherited-diseases.html Medical research Tue, 26 Feb 2013 11:39:36 EST news281101152 Results from a recent study show that novel vaccine combinations can provide partial protection against infection by Simian Immunodeficiency Virus (SIV) in rhesus monkeys. In addition, in the animals that became infected, the optimal vaccine combinations also substantially reduced the amount of virus in the blood. Results from the studies were published online today in the journal Nature. http://medicalxpress.com/news/2012-01-experimental-vaccine-partially-monkeys-hiv-like.html HIV & AIDS Wed, 04 Jan 2012 13:00:03 EST news244898042 Researchers at The Scripps Research Institute have uncovered the surprising details of how a powerful anti-HIV antibody grabs hold of the virus. The findings, published in Science Express on October 13, 2011, highlight a major vulnerability of HIV and suggest a new target for vaccine development. http://medicalxpress.com/news/2011-10-scientists-reveal-picture-powerful-antibody.html HIV & AIDS Thu, 13 Oct 2011 14:00:09 EST news237732653 Researchers at Duke University Medical Center, Beth Israel Deaconess Medical Center and Harvard Medical School have demonstrated an approach to HIV vaccine design that uses an altered form of HIV's outer coating or envelope protein. http://medicalxpress.com/news/2011-09-hiv-vaccine-approach-desirable-immune.html HIV & AIDS Thu, 01 Sep 2011 17:31:33 EST news234117057 Specific types of "helper" T cells that are crucial to maintaining functioning immune systems contain an enzyme called PDI (protein disulfide isomerase). http://medicalxpress.com/news/2011-06-sugar-binding-protein-role-hiv-infection.html HIV & AIDS Tue, 14 Jun 2011 07:45:07 EST news227256222
