Abstract:
The effect of immunisation with virus non-producer Marek's disease (MD) lymphoma-derived lymphoblastoid cells on virus replication and lymphoid organ pathogenesis following MD virus challenge was studied with chickens from two related inbred lines and their F(1 )offspring. Protection against peripheral blood lymphocyte-associated viraemia as well as MD virus-caused weight changes of the spleen and bursa of Fabricius and degenerative bursal lesions was significantly greater among syngeneic and semi-syngeneic (F(1)) recipients than among allogeneic recipients of the lymphoblastoid cells. The results suggest that the protective immunity observed may be major histocompatibility complex (MHC) antigen-restricted and that non-infectious MD virus-transformed cells possess antigens that can induce anti-viral immunity.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
