Figure 2.

H-L-g7xK mice develop lymphoid-like tissue. H-L-g7xK mice were evaluated for lymphoid infiltration in the lung. (A) Lymphoid-like lesions were found in the large airways of H-L-g7xK mice (magnification, ×10). (B) Higher magnification was focused on bronchus-associated lymphoid tissue (BALT)–like area (magnification, ×20). (C) Example of peribronchial and perivascular lymphocytic infiltration (magnification, ×10). (D) Smaller airway with an example of peribronchial lymphocytic infiltration in an H-L-g7xK mouse (magnification, ×20). (E) H-L-g7xK, K/BxN, and H-Lx-K lungs were scored for the presence of lymphoid-like tissue or lymphocytic peribronchial infiltrates according to the appearance of the histology, as already described.
