Objective To investigate the effect of Schistosoma japonicum ova on the expression of intestinal NOD2/CARD15 in the mice induced by 2,4,6-trinitrobenzesulfonic acid (TNBS). Methods Mice (n=50) in the experiment were randomly allocated into 3 groups: control group (n=10), TNBS+saline (n=20) and TNBS+Schistosoma japonicum ova (n=20). TNBS enema (100 mg/kg) was applied to the two TNBS groups in order to establish a colonitis model. Schistosoma japonicum ova was administered i.p. on the 14~(th) and 3~(rd) day before the instillation of haptenating agent. All mice were killed on the 7~(th) day after colitis induction. The transcription level of NOD2 in colon tissues was measured by Real time PCR, and the expression of NOD2 protein was measured by Western blot. Results The transcription and protein levels of NOD2 in TNBS-induced mice increased statistically compared with those of the normal group (P<0.05). Compared with the TNBS-induced mice, Schistosoma japonicum ova-treated ones exhibited a statistical reduction of gene and protein expression (P<0.05). Conclusions TNBS-treated mice exhibited a statistical increased expression of NOD2/CARD15, Schistosoma japonicum ova treatment reduced the severity of experimental colitis through down-regulating NOD2/CARD15.

The impairment of learning and memory function in the central nervous system(CNS)is one of the main features of aging and Alzheimer' s disease (AD). Many experimental results have showed that long- term memory(LTM) is related to long- term potentiation(LTP) and long- term depression (LTD). They intluenee each other. The relationship between LTP and LTD is complex. Therefore, it is important to study the learning and memory mechanism from LTP、LTD and gene expression in the CNS.
