2015考研英语阅读集中练:Combating addiction

  THE idea of vaccinating drug addicts against their affliction is an intriguing one.

  In principle, it should not be too hard.

  The immune system works, in part, by making antibodies that are specific to particularsorts of hostile molecule.Such antibodies recognise and attach themselves to these molecules, rendering themharmless.

  Vaccines work by presenting the immune system with novel targets, so that it can learn toreact to them if it comes across them again.

  The problem is that the molecules antibodies recognise and react to are the big ones, suchas proteins, that are characteristic of bacteria, viruses and other infectious agents.

  Small molecules, such as drugs, go unnoticed.But not for much longer, if Kim Janda of the Scripps Research Institute in San Diego has hisway.

  In a paper just published in the Journal of the American Chemical Society, Dr Janda and hiscolleagues suggest how a vaccine against methamphetamine, a popular street drug, mightbe made.

  If their method works, it would open the possibility of vaccinating people against other drugs,too.

  The idea of a methamphetamine vaccine is not new.The problem is getting the immune system to pay attention to a molecule that is such asmall target.The way that has been tried in the past is to build the vaccine from several components.
