Figure 5.
Chemokine protein levels in the lungs of young (white bar) and adult (black bar) mice throughout time after inoculation (n = 3 per group). Asterisks indicate statistically significant higher or lower chemokine levels in adult mice (P < 0.05) compared to young BALB/c mice. Adult mice showed earlier induction of MCP-1, MIP-1, and IP-10 in the lungs than young mice but these three chemokines and MIG and VEGF were at significantly higher levels in the lungs of young mice on day 2 after inoculation.
