Abstract: We have previously shown that neonatal rats with graft versus host disease (GVHD) (1) synthesize significantly less cerebellar RNA, (2) have RNA that is less translationally active, and (3) have changes in the relative abundance of certain mRNAs, including the induction of one coding for protein r that is present neither in control cerebellum nor in other brain regions at any age. Here we report on the ability of the cerebellum to recover from GVHD‐induced changes in the synthesis of total RNA and in the relative levels of specific mRNAs. In order to halt the disease, 11‐day‐old diseased Fischer animals were injected with hyperimmune alloantiserum daily for 3 days. Cytoplasmic RNAs were isolated from the cerebella of 14‐day‐old serum‐treated animals, their diseased littermates that were not treated with serum, and litter‐mate controls. Comparison, by two‐dimensional gel analysis, of the in vitro synthesized mRNA translation products showed that most GVHD‐induced alterations in the levels of specific mRNAs were not present in serum‐treated animals. In particular, protein r was not synthesized by cerebellar RNAs isolated from serum‐treated animals. These results show that the adverse effects of this disease are reversible at the molecular level.
