Micea | MAb treatmentb | MSTc | D/Td | Chitin content (mean μg of glucosamine ± SEM/pair of lungs)e |
---|---|---|---|---|
DBA/2 → C3H/HeJ | Control | 5 | 8/8 | 49 ± 4 |
DBA/2 → C3H/HeJ | K10 | >60f | 3/8 | 13 ± 1g |
Neutropenic DBA/2 | Control | 6 | 8/8 | 44 ± 5 |
Neutropenic DBA/2 | K10 | >60f | 0/8 | 17 ± 2g |
Recipient C3H/HeJ mice were lethally irradiated, received, transplants of T-cell-depleted BM cells from DBA/2 mice, and were infected 3 days later with 2 × 107 A. fumigatus conidia that were given intranasally for 3 consecutive days. DBA/2 mice were treated with an anti-Ly6G (RB6-8C5) MAb that was given intraperitoneally at a dose of 100 μg per injection on the day before and 2 days after the first fungal intranasal inoculation.
Control or K10 MAb was administered intranasally at a dose of 1 μg per injection twice a day on the day before the first fungal challenge and 1, 2, and 3 days later.
MST, median survival time in days.
D/T, number of dead animals/total number of infected mice.
Chitin content in the lungs was evaluated 1 day after the last fungal inoculation.
Significantly different (P < 0.05) from the value for untreated mice as calculated by the Mann-Whitney U test.
Significantly different (P < 0.05) from the value for untreated mice as calculated by Student's t test.
