In other studies [6, 9], the bursa of Fabricius, thymus, caecal tonsil, and spleen were collected 4 days postinoculation of Quail2006 isolate (velogenic strain) in commercial 5 weeks old broiler chickens, whereas the bursa of Fabricius, thymus, Harderian gland
, caecal tonsil, bone marrow, and spleen were collected 4 days postinoculation of LaSota (lentogenic strain) in another group of 5-week-old broiler chickens.
Specimens for histopathology were obtained from 10 chicken of each group at 15, 25 and 30 days old in order to examine the pathological changes in thymus and Harderian gland
. All specimens were processing and stained with Hematoxylin and Eosin stain and examined under the light microscope .
High relative expression levels of goose IFITM3 were detected in the Harderian gland
and lung compared to the other tissues (Figure 5).
porphyrin: A red discharge from the Harderian gland
, located behind the eyes of many rodents.
The team was also able to transplant lipid-secreting harderian glands
, which are also essential for good tear function.

This happens because the harderian glands
in their eyesproduce red pigments called porphyrins.
