The finding opens the way for the development of a new type of anti-HIV drug based on acyclovir.http://www.biologynews.net/archives/2008/09/10/herpes_drug_acyclovir_also_suppresses_hiv_i... How STDs increase the risk of becoming infected with HIV- September 7, 2008 Individuals who have a sexually transmitted disease (e.g., genital herpes, gonorrhea, syphilis, and chlamydia) and women with yeast and bacterial vaginal infections have an increased risk of becoming infected with HIV if exposed to the virus through sexual contact. Although several explanations have been proposed, exactly how and why STDs have this effect has not been clear. Now, Teunis B.H. Geijtenbeek and colleagues, at VU University Medical Center, The Netherlands, have described a way in...http://www.biologynews.net/archives/2008/09/07/how_stds_increase_the_risk_of_becoming_infe... Atomic structure of the mammalian 'fatty acid factory' determined- September 5, 2008 Mammalian fatty acid synthase is one of the most complex molecular synthetic machines in human cells. It is also a promising target for the development of anti-cancer and anti-obesity drugs and the treatment of metabolic disorders. Now researchers at ETH Zurich have determined the atomic structure of a mammalian fatty acid synthase. Their results have just been published in Science magazine.http://www.biologynews.net/archives/2008/09/05/atomic_structure_of_the_mammalian_fatty_aci... New 'trick' allows HIV to overcome a barrier to infection- September 4, 2008 Researchers have discovered a new 'trick' that allows HIV to overtake resting T cells that are normally highly resistant to HIV infection, according to a report in the September 5th issue of the journal Cell, a Cell Press publication. The binding of the virus to the surface of those cells sends a signal that breaks down the cells' internal skeleton, a structure that otherwise may present a significant barrier to infection.http://www.biologynews.net/archives/2008/09/04/new_trick_allows_hiv_to_overcome_a_barrier_... |
