New Insights Into HIV Immunity Suggest Alternative Approach to Vaccines

...niversity Medical Center researchers as to how HIV evades the human immune system may offer a new approach for developing HIV vaccines. The findings suggest some HIV vaccines may have failed because they induce a class of antibodies that a patient's own immune system is programmed to destroy. The Duke team...

Ancient immune defense mechanism is no match for HIV-1

...utic strategies making use of RNAi. "Because HIV-1 evades all other RNAi by point mutations, we reason that its requirement for an SRS is solely to shield this last 'Achilles' heel that we think HIV-1 cannot alter for functional reasons. The sequence we describe may represent a viable target for RNAi that H...

Newly discovered protein an important tool for sleeping sickness research

...eating African sleeping sickness. The trypanosome evades the human immune system because it is coated with a surface antigen called variant surface glycoprotein (VSG). The human body makes antibodies for VSG, but trypanosomes randomly switch to another antigen when the organisms divide and reproduce. Trypa...

MSKCC researchers uncover structure of key protein complex in cells

...or destruction. But in cells with damaged DNA, p53 evades getting tagged with ubiquitin to allow its accumulation, thus enabling the p53 suppressor protein to stifle the formation of tumors. Three scientists -- two Israelis and an American -- were awarded the 2004 Nobel Prize in Chemistry for their work sh...

MRSA use amoeba to spread, new research shows

The MRSA 'superbug' evades many of the measures introduced to combat its spread by infecting a common single-celled organism found almost everywhere in hospital wards, according to new research published in the journal Environmental Microbiology. Scientists from the Universit...

Study shows how herpes infects cornea, evades immune cells

...nfecting cornea cells that may also explain how it evades the immune system, according to a study by researchers at the University of Illinois at Chicago College of Medicine. The study appears in the Sept. 25 issue of the Journal of Cell Biology. Both strains of the herpes virus -- HSV-1, the strain tha...

The quest for an effective HIV vaccine presents new possibilities, challenges

...rts to improve our understanding of HIV and how it evades the immune system, to design new vaccine candidates and to assess the most promising ones in clinical trials." Dr. Johnston adds, "An important research challenge is to determine if these so-called T-cell vaccines that primarily induce a cellular...
