Figure 3. Quantification of leukocyte subsets in the BALF of mice instilled with increasing doses of two archaeal species.

Figure 3

A) Total immune cell numbers in BALF of mice instilled with 6.25, 25 or 100 µg of MBS or MSS for 3 weeks. B) Leukocyte subset numbers in BALF of mice exposed to 6.25, 25 and 100 µg of MBS for 3 weeks. C) Leukocyte subset numbers in BALF of mice exposed to 6.25, 25 and 100 µg of MSS for 3 weeks. Results expressed as average ± SEM. For both archaeal species, BALF cell subtypes were mainly composed of macrophages and lymphocytes. MSS also induced a significant accumulation of eosinophils and of neutrophils. Letters a and b represent statistical differences between treatment regimens within a same cell type. Results from two pooled experiments obtained with similar results are presented and 14 to 22 mice per group were analyzed. p<0.05.
