Critical considerations for adenovirus-based HIV vaccine trials

A clinical trial testing a candidate HIV vaccine known as the STEP study was halted in September 2007 after interim analysis indicated that the vaccine did not work. Moreover, subsequent analyses indicated that the vaccine made some individuals more susceptible to HIV, in particular individuals who had pre-existing immune effectors (antibodies) that recognized a component of the vaccine (adenovirus serotype 5 [Ad5]).

Synthetic drugs treat Crohn's disease in mice

A team of Weizmann Institute scientists has turned the tables on an autoimmune disease. In such diseases, including Crohn's and rheumatoid arthritis, the immune system mistakenly attacks the body's tissues. But the scientists managed to trick the immune systems of mice into targeting one of the body's players in autoimmune processes, an enzyme known as MMP9.
