Table 1.
Parameter | Stable SIV infection2 | Progressive SIV infection3 |
---|---|---|
Number of mDCs in blood | Increased to ~200% of pre-infection levels4 | Decreased to 60% of pre-infection levels |
Activation of mDCs in blood | Minor increase in CCR7; CD80/86 elevated | Major increase in CCR7; CD80/86 elevated |
Proportion of mDCs in lymph node | Similar to naïve | Similar to naïve |
Activation of mDCs in lymph node | CCR7, CD40, CD86, MHC class II low | CCR7, CD40, CD86, MHC class II normal |
Expression of CCL19 mRNA in lymph node | Similar to naïve | 8-fold higher than naïve |
Apoptosis of mDCs in lymph node | Similar to naïve | 3-fold higher than naïve |
Data adapted from [53]
Healthy at elective sacrifice at a mean of 60 weeks post infection (range 56 to 63 weeks)
Sacrificed due to AIDS-defining illness at a mean of 32 weeks post infection (range 11 to 43 weeks)
Blood mDCs in stable infection had initial decline at 2 weeks post infection
