FIG. 4.

Indicators of lung damage in CD4⁺-depleted CXCR2-KO and BALB/c wild-type (WT) mice 35 days after inoculation with 10⁷ Pneumocystis organisms, as well as those in nondepleted, noninfected BALB/c control mice (CON). (Upper panel) Respiratory rates determined by whole-body plethysmography, expressed in breaths per minute. (Center panel) Oxygen partial pressures in arterial blood (PaO₂), measured in millimeters of mercury (mm Hg). (Bottom panel) Albumin concentrations in BAL fluid in milligrams per milliliter. Values are means ± SD. n = 5. Results shown are representative of those from two independent experiments.
