Figure 1.

K/BxN mice develop perivascular and peribronchial lymphocytic infiltrates in the lungs. K/BxN mice were evaluated for lymphoid infiltration in the lung. (A) Representative lung with no infiltrates is shown (magnification, ×10). (B) K/BxN lung exhibited multiple areas of lymphocytic infiltration around vessels (arrowheads) and airways (arrows) (magnification, ×4). (C) Higher magnification of lung in B demonstrates peribronchial infiltrates around large airways (magnification, ×10). (D) Higher magnification of infiltrates around small airways and vessels (magnification, ×10).
