Multiple sclerosis(MS)is a neuroinflammatory demyelinating disease,mediated by pathogenic T helper 17(Th17)***,the therapeutic effect is accompa-nied by the fluctuation of the proportion and function of Th17 cells,which prompted us to find the key regulator of Th17 differentiation in ***,we demonstrated that the triggering receptor expressed on myeloid cells 2(TREM-2),a modulator of pattern recognition receptors on innate immune cells,was highly expressed on pathogenic CD4-positive T lymphocyte(CD4^(+)T)cells in both patients with MS and experimental autoimmune encephalomyelitis(EAE)mouse *** knockout of Trem-2 in CD4^(+)T cells significantly alleviated the disease activity and reduced Th17 cell infiltration,activation,differentiation,and inflammatory cytokine production and secretion in EAE ***,with Trem-2 knockout in vivo experiments and in vitro inhibitor assays,the TREM-2/zeta-chain associated protein kinase 70(ZAP70)/signal transducer and activator of transcription 3(STAT3)signal axis was essential for Th17 activation and differentiation in EAE *** conclusion,TREM-2 is a key regulator of pathogenic Th17 in EAE mice,and this sheds new light on the potential of this therapeutic target for MS.

作者： Ning Yu Yufei Qin Wenhan Kang Jiukai Zhang Lijia Chen Hongtian Wang Xiaoyan Wang Ying Chen Chinese Academy of Inspection and Quarantine College of Food Science and Engineering Nanjing University of Finance and Economics Food allergy department Beijing Shijitan Hospital Capital Medical University

Sesame is one of the eight major allergens that cause food allergies. Study of the epitopes of sesame allergens is important for understanding their sensitization mechanisms. Currently， less information is available on the epitope studies of sesame allergens. In this study， we analyzed the molecular characteristics， structure and homology of Ses i 3， one of the important sesame allergens. We predicted the B-cell linear epitopes of Ses i 3 using bioinformatics tools and characterized them by slot blot immuno-microarrays technology. Eight peptides as B-cell linear epitopes of Ses i 3 were identified， in addition， key amino acids in these epitopes were predicted and leucine 422 was identified as a key amino acid. The present work will contribute to further understanding of the sesame allergen and provide some help in the prevention and treatment of sesame allergy.
