The macrophages of mice in 3 groups collected from respective peritoneal cavities were prepared into two kinds of specimens, including slide and nitrocellulose membrane (NCM). The iNOS mRNA, iNOS and hsp 70 were detected respectively with in situ hybridization, cytochemistry, immunohistochemistry and RNA and protein dot blots. The results showed that the signals of iNOS mRNA and iNOS product were localized in the macrophage cytoplasm; the immunoreactivity(IR) of hsp 70 localized in both cytoplasm and nucleus. The dot blot signal scanning value of those in 3 groups in comparison with each other showed as follows: EA group>C 2 group>C 1 group, (P<0.01).展开更多

In addition, some HSPs are new immunoactive molecules which play important roles in both adaptive and innate immunity. They could activate CD8 + and CD4 + lymphocytes, induce innate immune response including natural killer (NK) cell activation and cytokine secretion, and induce maturation of dendritic cells (DCs). These characteristics have been used for immunotherapy of various types of cancers and infectious diseases. This review focuses on the main HSP families——HSP70 and 90 families. The mechanism of HSPs′ function in eliciting immune response are elucidated and various forms of HSPs used in immunotherapy are discussed in details. At the end of this review, authors summarize clinical trials related to HSPs and evaluate their clinical efficacy.展开更多
