Figure 4

No differences in the open field activity between RAG-1^−/−/OT-I, RAG-1^−/−/OT-II and RAG-1^−/−. The bar graphs show the total number of rears, the latency to rear (expressed in seconds) and squares crossed in RAG-1^−/−/OT-I (a) or RAG-1^−/−/OT-II (b) compared with RAG-1^−/− during the 5-min open field test. Values are expressed as mean±s.e.m. of six mice and are representative of n=3–4 separate experiments. *P<0.05 indicates significant values compared with RAG-1^−/− mice (Mann–Whitney U-test).
