Medicare Medical Care, Rapid Development of Drug-Resistant, 2009 H1N1 Influenza Reported in Two Cases Two people with compromised immune systems who became ill with 2009 H1N1 influenza developed drug-resistant strains of virus after less than two weeks on therapy, report doctors from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. Doctors who treat prolonged influenza infection should be aware that even a short course of antiviral treatment may lead to drug-resistant virus, say the authors, and clinicians should consider this possibility as they develop initial treatment strategies for their patients who have impaired immune function....
  6. Scientists find approach to enhance and prolong immune attack against tumor cells Investigators have identified a new class of human immune cells that behave like stem cells. These cells, a subtype of T lymphocytes, which comprise a small fraction of white blood cells, may prove more effective than any previously reported type of T cell for treating tumors. The study, by scientists at the National Cancer Institute […]...

  8. Cells’ energy factories linked to damaging inflammation Scientists have discovered that molecules called reactive oxygen species (ROS) produced by the energy factories, or mitochondria, in cells, may play a role in a rare inherited disorder in which uncontrolled inflammation damages the body’s tissues. Their research in human and mouse cells suggests that blocking these molecules could reduce inflammation in TNF receptor-associated periodic […]...

Origins of XMRV deciphered, undermining claims for a role in human disease Delineation of the origin of the retrovirus known as XMRV from the genomes of laboratory mice indicates that the virus is unlikely to be responsible for either prostate cancer or chronic fatigue syndrome in humans, as has been widely published. The virus arose because of genetic recombination of two mouse viruses. Subsequent infection of lab […]...
