immune system

parotid gland inflammation ( J:172701 )

• between 8 and 12 months

submandibular gland inflammation ( J:172701 )

• between 8 and 12 months

abnormal T cell differentiation ( J:172701 )

• as detected by marker expression, T cell development from the double positive to single positive stage is delayed compared to in wild-type mice

• however, single positive cells are able to enter the medulla

increased CD4-positive, alpha-beta memory T cell number ( J:172701 )

• slightly and unchanged by age

increased CD8-positive, alpha-beta memory T cell number ( J:172701 )

• slightly and unchanged by age

increased gamma-delta T cell number ( J:172701 )

• in the thymus

decreased T cell number ( J:172701 )

• the number of mature alpha-beta T cells in the thymus is decreased compared to in wild-type mice

decreased CD4-positive, alpha-beta T cell number ( J:172701 )

• in the thymus

• in the spleen of young mice

• however, numbers are normal in aged mice

decreased CD8-positive, alpha-beta T cell number ( J:172701 )
