Strong cytoplasmic positivity was observed in lung macrophages, subsets of renal tubules, fraction of Leydig cells, cells in white pulp of spleen, hematopoietic cells and cardiac myocytes. Remaining normal tissues were weakly stained or negative.
Gastrointestinal tract, type 2 pneumocytes in lung, adrenal glands, parathyroid, cardiomyocytes, renal tubules and Leydig cells showed moderate to strong cytoplasmic and/or nuclear positivity. Other normal tissues were generally negative.
Type II pneumocytes of lung and renal tubules exhibited strong cytoplasmic immunoreactivity in granular pattern. Remaining normal tissues were negative.
Alveolar macrophages, alveolar type II cells and renal tubules showed strong cytoplasmic positivity. Remaining normal tissues were negative.
