New dent in HIV-1′s armor: promising target for HIV/AIDS treatment

New dent in HIV-1′s armor: promising target for HIV/AIDS treatment

Like a slumbering dragon, HIV can lay dormant in a person’s cells for years, evading medical treatments only to wake up and strike at a later time, quickly replicating itself and destroying the immune system. Scientists at the Salk Institute have uncovered a new protein that participates in active HIV replication, as detailed in the latest issue of Genes & Development . The new protein, called Ssu72, is part of a switch used to awaken HIV-1 (the most common type of HIV) from its slumber. Continue reading

German academies call for consequences from the Ebola virus epidemic

German academies call for consequences from the Ebola virus epidemic

The Ebola virus is spreading rapidly and to an unexpected extent. The outbreak does not follow the patterns experienced in the past and the virus shows a new disease dynamic in regions where it has never been recorded before. For this reason, the German National Academy of Sciences Leopoldina, acatech — the German Academy of Science and Engineering, and the Union of the German Academies of Sciences and Humanities have presented a statement on the Ebola epidemic today Continue reading

Universal Ebola drug target identified by researchers

Universal Ebola drug target identified by researchers

University of Utah biochemists have reported a new drug discovery tool against the Ebola virus. According to a study published in this week’s online edition of Protein Science , they have produced a molecule, known as a peptide mimic, that displays a functionally critical region of the virus that is universally conserved in all known species of Ebola. This new tool can be used as a drug target in the discovery of anti-Ebola agents that are effective against all known strains and likely future strains Continue reading

Ebola genome browser now online to aid researchers’ response to crisis

Ebola genome browser now online to aid researchers’ response to crisis

The UC Santa Cruz Genomics Institute late Tuesday (Sept. 30) released a new Ebola genome browser to assist global efforts to develop a vaccine and antiserum to help stop the spread of the Ebola virus. The team led by University of California, Santa Cruz researcher Jim Kent worked around the clock for the past week, communicating with international partners to gather and present the most current data.

Stem cell transplant does not cure SHIV/AIDS after irradiation of infected rhesus macaques

Stem cell transplant does not cure SHIV/AIDS after irradiation of infected rhesus macaques

A study published on September 25th in PLOS Pathogens reports a new primate model to test treatments that might cure HIV/AIDS and suggests answers to questions raised by the “Berlin patient,” the only human thought to have been cured so far. Being HIV-positive and having developed leukemia, the Berlin patient underwent irradiation followed by a bone-marrow transplant from a donor with a mutation that abolishes the function of the CCR5 gene.

Dengue fever, malaria in the Himalayas

Dengue fever, malaria in the Himalayas

Research by Nepalese and German scientists from the Nepal Health Research Council, Goethe University and the LOEWE Biodiversity and Climate Research Centre analyzes the current situation of these diseases in the Himalayan country of Nepal and highlights how they profit from climate change and globalization. Dengue fever: high risk, little knowledge Although the first case of dengue fever in Nepal was only reported in 2004, the country was shaken by an epidemic already in 2010 Continue reading

Possible 6,800 new Ebola cases this month, research predicts

Possible 6,800 new Ebola cases this month, research predicts

New research published today in the online journal PLoS Outbreaks predicts new Ebola cases could reach 6,800 in West Africa by the end of the month if new control measures are not enacted. Arizona State University and Harvard University researchers also discovered through modelling analysis that the rate of rise in cases significantly increased in August in Liberia and Guinea, around the time that a mass quarantine was put in place, indicating that the mass quarantine efforts may have made the outbreak worse than it would have been otherwise. Deteriorating living and hygiene conditions in some of the quarantined areas sparked riots last month Continue reading
