Th1/Th2 balance in canine peripheral blood lymphocytes--a flow cytometric study.

The canine immune system undergoes continuous remodeling with advancing age. We measured the Th1/Th2 balance in peripheral blood lymphocytes (PBLs) obtained from 23 Beagles ranging in age from 0.5 to 11.

Immunological effects of recombinant feline interferon-omega (KT-80) administration in the dog.

The immunological effects of recombinant feline interferon-omega (rFeIFN-omega ; KT-80, Toray) were examined on administration to healthy dogs. The activities of whole blood cells, macrophages, and natural killer cells were enhanced. Moreover, the whole blood activity was examined when KT-80 was administered to dogs which had been diagnosed as having natural canine parvovirus (CPV) infection.
