Impact of antibiotics and probiotic aerosolization on J chain protein expression in the lung. Lung parenchyma (A) and intratumoral tissue (B) J chain protein level in formalin-fixed, paraffin-embedded lung specimens evaluated by IHC. Data are expressed as positive cells/mm² (4 section/lung, 8–9 mice/group) (mean ± SEM). Lung parenchyma and intratumoral tissue representative staining with anti-mouse J chain antibody in saline- (C,G), vanco/neo- (D,H), live L.RGG- (E,I) and heat-killed L.RGG- (F,J) treated lungs are shown; 20× magnification. * p ≤ 0.05 by unpaired Student t-test.
