Exploration the significance of Tfh and related molecules on C57BL/6 mice model of experimental autoimmune hepatitis.

Background: This study aimed at establishing the autoimmune hepatitis (AIH) model of C57BL/6 mice, and examining the expression and significance of T follicular helper (Tfh) cells, T follicular regulatory (Tfr) cells, effector B cells and other indicators in this experimental autoimmune hepatitis (EAH) model.

Methods: C57BL/6 mice in experimental group were administered by intraperitoneal injection after fully emulsified on 1st day and 7th day with 0.5 mL of 0.

Nocardiopsis rhizosphaerae sp. nov., isolated from rhizosphere soil of Halocnermum strobilaceum (Pall.) Bieb.

An alkalitolerant actinomycete strain, designated EGI 80674T, was isolated from a rhizosphere soil of Halocnermumstrobilaceum (Pall.) Bieb in Xinjiang, north-west China and subjected to a taxonomic characterization using a polyphasic approach. Strain EGI 80674T formed white aerial hyphae with long spore chains.

Lipingzhangella halophila gen. nov., sp. nov., a new member of the family Nocardiopsaceae.

An alkaliphilic and halophilic actinomycete strain, designated EGI 80537T, was isolated from a saline-alkali soil sample of Xinjiang, north-west China and subjected to a taxonomic characterization using a polyphasic approach. Strain EGI 80537T formed reticulate long aerial hyphae. Whole-cell hydrolysates of the isolate contained meso-diaminopimelic acid as the cell-wall diamino acid and mannose as the diagnostic sugar.

Phytoactinopolyspora alkaliphila sp. nov., an alkaliphilic actinomycete isolated from a saline-alkaline soil.

An alkaliphilic, filamentous actinomycete, designated EGI 80629T, was isolated from a soil sample of Xinjiang, north-west China. Strain EGI 80629T grew at pH 6.0-11.

Tomitella cavernea sp. nov., an actinomycete isolated from soil.

A Gram-staining-positive, aerobic, non-spore-forming, irregular rod-shaped actinobacterium, designated YIM C00895(T), was isolated from a soil sample collected from Jiuxiang Scenic Region, Yunnan province, south-west China. The strain was able to grow at 10-28 °C, pH 6.0-10.

Improved methods of isolation and purification of myxobacteria and development of fruiting body formation of two strains.

By using baiting techniques and different purification methods, a high number of myxobacterial strains have been isolated as pure cultures from soil of different regions of China. Because myxobacterial cells do not disperse easily in liquid media, a medium containing an enzymatic hydrolysate of casein (CEH) medium have been used for purification and purity tests combined in a single step. The key method, in which isolates are reintroduced to sterile rabbit dung to induce fruiting bodies formation, facilitates purification of myxobacteria.
