NK cells from subjects carrying <i>*h/*y+B*57</i> and <i>3DS1+*80I</i> suppress viral replication better than those from <i>Bw6hmz</i> and <i>*l/*x+B*57</i> carriers.

<p>The box and whisker plots show the percent viral inhibition observed when NK cells from subjects positive for <i>*h/*y+B*57</i> (n = 7) <i>3DS1+*80I</i> (n = 9), <i>Bw6hmz</i> (n = 10) and <i>*l/*x+B*57</i> (n = 4) are cultured with autologous HIV infected CD4 (iCD4) cells at a ratio of 10∶1 for up to 10 days. The line in each box represents the median value, the lower and upper limits of the boxes the 25% and 75% quartiles and the whiskers the minimum and maximum values for each group; each point is the percent viral inhibition value for a single individual. Lines linking groups indicate comparisons where medians were significantly different. “*” = p<0.05, “**” = p<0.01.
