Small increases or 'blips' in HIV levels do not signal mutations leading to drug-resistant HIV
...ns were found in an analysis of nearly 1,000 viral clones
for mutations in HIV's two key enzymes which are blocked by drug therapy, protease and reverse transcriptase. The authors also found that blips were not, again, detected when blood samples were assayed twice in independent laboratories. "The lack o...

...oning CD8+ cells from people with latent TB. These clones
will be used to help the team identify the antigens and epitopes. "From an immunologist's standpoint, TB is a really challenging disease to work on because we need to understand how the cellular system works in order to create better vaccines," David...
Reprogrammable cells from fat are true adult stem cells

of these cells for up to 25 doublings. The cells w...further investigations," Guilak said. "More of the clones
developed into bone, cartilage and nerve cells than they did into fat cells, which is another intere...
Increasing MRSA in California jails
...olleagues are attempting to understand why certain clones
are spreading so rapidly outside the hospital environment and what drives their resistance to numerous drugs. The ability to track the spread of individual strains is made possible by using techniques like Pulsed Field Gel Electrophoresis (PFGE) and ...
T cell clones shrink melanoma tumors
...ported in article #6000, indicate that the T cells clones
were able to home in on the tumors, which regressed slightly or stabilized in 8 of the 10 patients, for an average period of 11 months. In addition to T cells, the injections contained IL-2, a chemical that stimulates the T cells to replicate, resup...
