Inhibited proteases of leukocytic origin probably are partly responsible for the damage to the lung in the absence of the major protease inhibitor.
The ovalbumin-treated mice, but not the control mice, displayed widespread deposition of collagen beneath the airway epithelial cell layer and in the interstitium at sites of leukocytic infiltration.
The epithelium covering the tonsils is extensively infiltrated by lymphocytes, plasma cells, and polymorphonuclear leucocytes .
For all these cases, hepatocytes were more immunoreactive than endothelial cells and leukocytes .
Finally, there were other techniques for separating red blood cells from leucocytes .
White blood cells (also called leukocytes or WBCs) help the body fight infections.
Necrotic tissue, blood vessels, and leukocytes were excluded from the quantification process.
Immune cells or leukocytes circulate continuously from the blood, into various organs, and back into the blood.
Thus, changes in airway hyperresponsiveness between experimental groups did not result from differences in leukocytic infiltration into the lung in response to Aspergillus extract.
Some giant cells exhibited phagocytosis of mononuclear tumor cells and leukocytes such as lymphocytes and polymorphonuclear cells.
