Allergic rhinitis is a common disease, which was released by the IgE-mediated atopic individuals exposed to allergens in the earlier researches. However, there are variety of immunocompetent cells and cytokines involved in the nasal mucosa immunologic mechanism in nowadays researches. The mechanism of AR is caused by the imbalance of the Th1/Th2, a kind of allergic inflammation who is characterized by the nasal Th2 immune response dominant. Th1 cells mainly produce of IFN-gamma (does not include IL-4 and IL-5), Th2 cells produce IL-4, IL-5, IL-9 and IL-13 (not including IFN-gamma). Recently it was found that regulatory T cells (T regulatory cells, Treg) and Th17 cell research played a crucial role in the occurrence of allergic inflammation.

Objective To evaluate the impact of influenza virus hemagglutitin (HA) 306-318 peptide on T cell activation and to investigate the inhibitory effect of the altered HA306-318 peptide on T cell proliferation. Methods HA306-318 peptide and its mutant containing amino acid substitutions were synthesized. They were used in T cell activation assay using HLA-DR1 transfected cells. Responses were determined by MTT proliferation assays. The HA mutant without stimulating effect on T cells was then examined by inhibiting HLA-DR1-restricted T cell activation. Results It was demonstrated in this study that the altered HA306-318 peptide bound to HLA-DR1 molecule on L57.23 cells transfected with HLA-DR1 cDNA, but not on the control cells. The altered HA306-318 peptide had no stimulating effect on T cells compared with the wild type HA306-318 which induced T cell proliferation. It was shown that the altered HA peptide inhibited T cell activation mediated by wild type HA306-318 as well as by CⅡ263-272 which was the specific T cell antigen. Conclusions This study suggests that HA306-318 peptide is antigenic and can induce responses in HLA-DR1 specific T cells. Altered HA306-318 peptide is hyporesponsive in T cell activation with inhibitory effect on antigen-driven T cell responses, and it is potentially a therapeutic agent in rheumatoid arthritis.

AIM: To explore the way and the feasible time of olfactory ensheathing cells (OECs) transplanting to experimental autoimmune encephalomyelitis (EAE) rats, and to investigate the migration of OECs after transplanted to EAE and the possible mechanism of inducing the protective effect. METHODS: The Lewis rats, which were divided into MOG group and GPSCH group according to the induction by MOG~Igd and GPSCH separately, were used to made EAE model. The animals in MOG group were divided into 3 subsets: OECs blank group (MOG0 group, 4 rats );OECs transplantation by vena caudalis (MOG1 group, 7 rats);OECs transplantation by lateral cerebral ventricle (MOG2 group, 4 rats). The animals in GPSCH group were also divided into 2 subsets: OECs blank group (GPSCH0 group, 4 rats);OECs transplanted by vena caudalis (GPSCH1 group, 4 rats). OECs transplanted through different ways in peak incidence, then the rats were measured to determine whether the symptom was ameliorated. Two weeks after transplantion, the rats were killed and the methods of histofluorescence and histopathology (HE staining and Luxol fast blue staining) were used to examine the distribution of the labeled OECs in EAE rats' bodies and to explore whether there was some amelioration in histology. RESULTS: After OECs transplantation by vena caudalis or lateral cerebral ventricle, the rats' symptom improved. Compared to OECs blank groups, there was significant difference in clinical scores (F=18.470, P<0.01;t=-7.147, P<0.01). No significant difference between MOG1 group and MOG2 group was observed (P>0.05). The labeled OECs entered into the brain through the broken blood-brain-barrier after transplantation by vena caud-alis, the labeled OECs near the subpial area and around the lesions were found. OECs transplantation by the way of lateral cerebral ventricle showed great migration potential, the cells moved towards to the lesions extensively. No significant difference between OECs transplantation group and OECs blank group in histopathology (HE staining and LFB staining) was observed (P>0.05), and the same thing also happened between MOG1 group and MOG2 group (P>0.05). CONCLUSION: The transplantation of adult rats' OECs improves the EAE rats' symptom at some degree by the ways of vena caudalis or lateral cerebral ventricle.

Objective To obtain an accurate and effective method for thalamus segmentation based on resting-state functional magnetic resonance imaging (fMRI).Methods Based on the fact that resting-state fMRI technique examined spatial synchronization of spontaneous fluctuations in blood oxygen level-dependent (BOLD) signals indirectly reflect the neuronal and synaptic activity,the in-thalamus BOLD signal correlations were calculated,and then the k-means clustering algorithm was applied to obtain functional connectivity-based thalamus segmentation.Results The thalamus was divided into seven regions.Voxels within the same region were highly correlated with each other.The segmentation result was similar to that divided by functional connectivity between thalamus and the cerebral cortex.Conclusions Resting-state fMRI could provide not only the functional connectivity network between cortical and subcortical brain regions,but also the functional characteristics of thalamus.Segmentation algorithm using only internal information of thalamus shows lower computational complexity and higher processing speed than that based on the functional connectivity between thalamus and the cerebral cortex.
