title: Age-related decrease in the naive (OX22+) T cells in F344 rats.
abstract: The frequency of the cells bearing the naive marker (OX22+) in T cells, helper, and cytotoxic/suppressor T cell subsets isolated from the spleens of young and old F344 rats were measured by flow cytometry. The percentage of naive cells in T cells decreased significantly with age and this decline occurred primarily in the helper subset.
