Dengue virus (DENV) envelope [E] protein is the major surface protein of the virions that indued neutralizing antibodies. The domain III of envelope protein (EDIII) is an immunogenic region that holds potential for the development of vaccines; however, the epitopes of DENV EDIII, especially neutralizing B-cell linear epitopes, have not been comprehensively mapped. We mapped neutralizing B-cell linear epitopes on DENV-1 EDIII using 27 monoclonal antibodies against DENV-1 EDIII proteins from mice immunized with the DENV-1 EDIII. Epitope recognition analysis was performed using two set of sequential overlapping peptides (16m and 12m) that spanned the entire EDIII protein from DENV-1, respectively. This strategy identified a DENV-1 type- specific and a group-specific neutralizing epitope, which were highly conserved among isolates of DENV-1 and the four DENV serotypes and located at two regions from DENV-1 E, namely amino acid residues 309-320 and 381-392(aa 309-320 and 381-392), respectively. aa310 -319(310KEVAETQHGT319)was similar among the four DENV serotypes and contact residues on aa 309 -320 from E protein were defined and found that substitution of residues E309 , V312, A313 and V320 in DENV-2, -3, -4 isolates were antigenically silent. We also identified a DENV-1 type-specific strain-restricted neutralizing epitope, which was located at the region from DENV-1 E, namely amino acid residues 329-348 . These novel type- and group-specific B-cell epitopes of DENV EDIII may aid help us elucidate the dengue pathogenesis and accelerate vaccine design.

3.Evaluation of immune regulation effects of Chinese medicinal formulae based on immunomics of traditional Chinese medicine.
China Journal of Chinese Materia Medica 2008;33(24):2958-2960
OBJECTIVETo investigate the possibility of evaluation the Chinese medicinal formulae with immune regulation effects according to the immunomics of traditional Chinese medicine.
METHODThe possibility of Chinese medicinal formulae with immune regulation effects was obtained from the discriminant equation of the Chinese medicine with immune regulation effects. The original articles about the Chinese medicinal formulae with immune regulation effects were found since 1980 in CNKI. Using literatures determinate immune effects.
RESULTThere were 53 kinds, that with calculated determination, from total 60 Chinese medicinal formulae with literatures determinate on immune regulation effects. The coincidence was 88% (53/60). The discriminant score was 0. 89 +/- 0. 03 in group one (there were two or more than two articles have been published to support the medicines immune effects and the articles were finished by different unites independently) and was 0.60 +/- 0.29 in group of random Chinese medicinal formulae. There was a significant deviation (P < 0.05).
CONCLUSIONIt was proved preliminarily that the principle of calculation presented in this paper is valuable for the immunomics of traditional Chinese medicine.

OBJECTIVEIntends to create mathematical model and analysis of correlation between Chinese medicinal characteristics and immunoregulatory activity based on literature informatics.
METHODThe numbers of the Chinese medicines with immune effects were worked out within the framework of "The China Pharmacopeia" of 2005 edition, from the literature publicized since 1980. The correlation and mathematical model were figured out between Chinese medicinal characteristics including biological classification, different tastes, channel tropism as well as the parts used and immunoregulatory activity based on the statistical software SPSS.
RESULTThe results showed that the immunoregulatory activity was related to the five tastes of Chinese medicines, and the pungent medicines had less immune effect. The Chinese medicines of underground parts had more immune effect compared with other parts of the medicine. Medicines acting upon heart and kidneys were more powerful as for the immune effects (P <0.05). The coincidence was 74.7% between mathematical computing and original classification.
CONCLUSIONThere are correlations,between Chinese medicinal characteristics and immunoregulatory activity. The mathematical model based on these results can be used for immunopharmacology.
