Table 3. Cytokine and chemokine concentrations in PBMC cultures exposed to P. chrysogenum, C. herbarum, or media alone ex vivo.
PBMCs + Exposure | Mold-Exposed Patients | Unexposed Controls | Controls/ Patients | ||
---|---|---|---|---|---|
Cytokine or Chemokine | Mean ± SEM | Mean ± SEM | p-value | Fold Change | |
P. chrysogenum (4,000 spores/ml) | Eotaxin (pg/ml) | 23 ± 5 | 84 ± 14 | 0.00001 | 3.61 |
IL-8 (ng/ml) | 16.6 ± 4.7 | 63.7 ± 20.6 | 0.0026 | 3.84 | |
MCP-1 (ng/ml) | 4.8 ± 1.1 | 11.8 ± 2.0 | 0.005 | 2.42 | |
MIP-1α (ng/ml) | 1.4 ± 0.3 | 13.0 ± 5.5 | 0.0019 | 9.45 | |
MIP-1β (ng/ml) | 1.7 ± 0.4 | 7.8 ± 2.6 | 0.0017 | 4.57 | |
C. herbarum (10,000 spores/ml) | IL-1β (pg/ml) | 349 ± 83 | 2585 ± 678 | 0.008 | 7.41 |
IL-6 (pg/ml) | 486 ± 127 | 9596 ± 5304 | 0.0037 | 19.7 | |
MCP-1 (ng/ml) | 7.8 ± 2.2 | 2.6 ± 0.6 | 0.011 | 0.33 | |
MIP-1α (ng/ml) | 6.9 ± 1.5 | 17.6 ± 3.3 | 0.006 | 2.55 | |
Media | Eotaxin (pg/ml) | 16 ± 3 | 55 ± 7 | 0.00001 | 3.36 |
MIP-1α (ng/ml) | 0.11 ± 0.01 | 0.17 ± 0.01 | 0.0005 | 1.60 | |
RANTES (ng/ml) | 2.1 ± 0.4 | 5.2 ± 0.9 | 0.004 | 2.45 |
Cytokines and chemokines are listed alphabetically for each exposure. Only cytokines and chemokines whose concentrations were significantly different between mold-exposed patients and controls with an FDR q<0.05, and whose fold-changes were greater than in media alone are shown. Lower doses of P. chrysogenum and C. herbarum and all doses of A. niger did not cause significant changes (q<0.05) in cytokine and chemokine expression beyond that of the changes in eotaxin, MIP-1α, and RANTES that are visible in media alone. Log-transformed unadjusted case-control correlation was used to calculate p-values. Fold changes were calculated from case and control means.
