Leukemia virus activation in chronic allogeneic disease
Summary
In mice, injecting lymphoid cells activated latent leukemia viruses. This suggests autoimmune reactions might trigger latent viruses, a finding relevant to leukemia virus activation and autoimmunity research.
Area of Science:
- Immunology
- Virology
- Oncology
Background:
- Young adult (BALB/c x A/J)F(1) hybrid mice lack detectable leukemia viruses.
- Graft-induced allogeneic disease shares similarities with spontaneous autoimmunity.
Purpose of the Study:
- To investigate the activation of leukemia viruses in (BALB/c x A/J)F(1) hybrid mice.
- To explore the potential role of autoimmune reactions in latent virus activation.
Main Methods:
- Inoculation of young adult (BALB/c x A/J)F(1) hybrid mice with parental BALB/c spleen lymphoid cells.
- Monitoring for the activation of leukemia viruses in the host.
Main Results:
- Leukemia viruses were rapidly activated in the injected host mice.
- The activation occurred despite the absence of detectable viruses in the inoculated lymphoid cells.
Conclusions:
- Graft-induced allogeneic disease can lead to the activation of latent leukemia viruses.
- Autoimmune reactions are proposed as a potential mechanism for activating latent viruses.
