  五月，大家的論文寫得怎么樣了？
先我們要祝賀下來自南京農業大學的王老師，2021年王老師在《International Journal of Nanomedicine》（納米醫學雜志）發表了SCI文獻，發表的文獻影響因子(IF)達到了5.15分！然后讓我們恭喜王老師到了恒遠生物的獎學金！

這篇論文寫的非常棒，其中的很多實驗方法和思路值得我們閱讀，小編想要分享給大家，希望能夠對做實驗的小伙伴們有點點幫助，也希望大家積的參與我們的“發論文贏獎學金”活動，小編等著你們的投稿哦，下個獎學金的人說不定就是你！

Cytokine Assays
The levels of IL-4, IL-12, IL-17, IFN-γ, ａnd TGF-β in sera from the ten groups were investigated with commercial ELISA kits (HengYuan, Shanghai, China) according to the manufacturer’s guidelines.

Characterization of rHCA59-CS NPs ａnd rHCA59-PLGA NPs
After conjugation, PLGA ａnd Chitosan nanoparticles were precipitated ａnd the free amounts of rHCA59 protein were determined by a BCA protein assay kit. It was found that 89% ａnd 71% of rHCA59 were conjugated to PLGA ａnd Chitosan, respectively. In other words, a total of 1.78 mg of protein bound to PLGA, ａnd 1.42 mg of protein bound to Chitosan.A scanning electron microscopy was used to identify the size ａnd morphology of PLGA ａnd Chitosan nanoparticles. The SEM results showed that both PLGA ａnd Chitosan nanoparticles’ appearances were smooth. The size of rHCA59-PLGA NPs was from 180 nm to 402 nm (Figure 1A) ａnd the size of rHCA59-CS NPs was from 200 nm to 500 nm (Figure 1B).

Figure 5 Effects of different antigen delivery systems on T lymphocyte subsets.
Notes: rHCA59 loaded nanoparticles could affect the proportions of CD4+ T cells ａnd CD8+ T cells in immunized mice. The percentages of CD4+ T cells (A1–A10) ａnd CD8+ T cells (B1–B10) in ten groups were investigated by flow cytometry on day 14 after immunization. (C ａnd D) Different treatments affected the proportions of CD4+ T cells ａnd CD8+ T cells. (A1 ａnd B1) PBS group (blank control). (A2 ａnd B2) PBS-CFA group. (A3 ａnd B3) PBS-PLGA group.
