Inefficient immune killer cells abet HIV infection

...cLean, and their colleagues turned to mathematical modeling to measure the overall effect of the CTL response on the lifespan of infected cells in patients with HIV. Applying different metrics to 28 independent datasets spanning 14 years, the researchers found that CTLs kill roughly 10 million infected cells ...

According to computer modeling results, it is expected that comparisons among the 24 genome sequences will allow conserved sequences as small as six base pairs to be identified reliably. Six base pairs is roughly the size of a transcription factor binding site: a small DNA sequenc...
