...defective mice with tissue taken from human fetal thymus, where certain immune and blood cells develop, and with blood-forming cells from fetal liver. The implanted tissues soon produced mature human T cells, specialized white blood cells that help provide immunity against disease. Mice that additionally received fetal lymph tissue -- needed for the functioning of some immune cells -- also developed mature human B cells. All fetal tissues were obtained from legally aborted fetuses with the consent of the mothers...
...bone-marrow failure and boosts white-cell counts in AIDS patients. Gamma interferon seems to remedy the defective functioning of monocytes and macrophages in a wide variety of diseases. Alpha interferon has been particularly effective against two types of leukemia and non-Hodgkin's lymphoma, a cancer of the lymph system. Says Dr. Jordan Gutterman, of Houston's M.D. Anderson Hospital and Tumor Institute: "There are ten different tumors in which potentially important anti-tumor activity by interferon has been demonstrated...
...immune system slow, then shut down. Scientists believe that still other immune specialists, known as suppressor T cells, call off the battle. As the carnage wanes, the B cells and T cells perform a last, vastly important task: they form memory cells that circulate in the bloodstream and lymph system for many years, primed to spring into action should the same strain of flu virus ever attack again. In addition, the body is protected by specialized antibodies, strategically deployed in mucus, saliva and tears, that immediately recognize any return of this particular virus...
...Thousand Oaks, Calif., was 44 and the mother of two teenagers when she discovered a lump in her breast two years ago. Two mammograms suggested that it was malignant, and when a biopsy confirmed the diagnosis, Hamby underwent surgery and radiation treatments. Because cancer cells had invaded a lymph node, six months of grueling chemotherapy followed. She knows that the chance of a recurrence will remain high for about another year. Says Hamby: "My prognosis is good, but it would have been better if the cancer had been found before it reached the lymph nodes. And it would have been...
Whatever their age, women with small tumors that have not invaded the lymph nodes have a 90% chance of surviving at least five years. As the disease spreads, however, the odds of survival drop sharply. Thus cancer experts agree that a woman's best hope for a cure, whatever her age, lies in finding tumors early. Mammography can detect tumors as small as an eighth of an inch in diameter. By contrast, most cancers detected by patients themselves are at least half an inch in diameter, and have been growing for eight to ten years, says Dr. Ferris Hall...
