Figure 4. NK cells from subjects positive for *h/*y+B*57 secrete more CC-chemokines in response to autologous HIV infected CD4 (iCD4) cells than those from Bw6hmz.

Figure 4

Box and whisker plots show the levels of CCL3 (A), CCL4 (B) and CCL5 (C) secreted over 3 days into the supernatant of cultures of NK cells and autologous iCD4 cells at a 10∶1 ratio from individuals positive for *h/*y+B*57 (n = 7) or from Bw6hmz (n = 10). 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. Lines linking groups indicate comparisons where medians were significantly different.
