Figure 6From: Characterization of the innate immune response to chronic aspiration in a novel rodent modelChanges in CD4:CD8 T cell ratios as a result of chronic aspiration of gastric fluid. Relative CD4:CD8 T cell ratios in bronchoalveolar lavage (BAL) specimens following aspiration of either gastric fluid or normal saline are shown. †p < 0.10, **p < 0.01 based on two-tailed Student's t test.Back to article page
