...rude shock, for they encounter one of nature's most incredible and complex creations: the human immune system. Inside the body, a trillion highly specialized cells, regulated by dozens of remarkable proteins and honed by hundreds of millions of years of evolution, launch an unending battle against the alien organisms. It is high-pitched biological warfare, orchestrated with such skill and precision that illness in the average human being is relatively rare...
...thought to be autoimmune. Among them: Type 1 diabetes, myasthenia gravis, multiple sclerosis, rheumatoid arthritis and systemic lupus erythematosus. In these and other autoimmune diseases, the immune system mounts a selective and ferocious assault against parts of the body, destroying cells or cell components that it mistakenly identifies as alien...
Ever since the pioneering transplant operations of the 1960s, the chief obstacle to the full recovery of transplant patients has been the immune system's xenophobic zeal to destroy anything that is foreign to the body. Once the alien threat has been identified, agents known as helper T cells unleash the powerful immune response that attacks grafted tissue. During the 1970s, physicians found that they could minimize this reaction by more closely matching the MHC proteins, or immunological "dog tags," of a donor with those of the recipient. Even so, they could not completely eliminate the rejection response. To make...
...immune system is made up of a trillion specialized cells, regulated by powerful biochemicals, that wage an unending war on alien organisms that cause illness, suffering and death. Spurred along by the AIDS epidemic, research into its complex and wondrous workings is bringing about promising developments in the treatment of deadly diseases. See MEDICINE...
Part of the problem in depicting a Dukakis presidency, of course, is that soaring poetry and air castles of ideas are as alien to Dukakis as they are natural to Jesse Jackson. But in fairness, it must be said that the reality of a Dukakis presidency would be more uplifting than its anticipation. As a pragmatic problem solver, Dukakis is often at his best reacting decisively rather than initiating boldly. "Michael likes to make decisions," Hale Champion, the Governor's chief of staff, has said. "He never stalls to get irrelevant information. His basic impulse is to get on with...
