DH-PS induced the secretions of multiple cytokines and
chemokines in vivo
In order to understand the immunological activities of DH-PS,
we investigated the profiles of cytokines and chemokines induced
by DH-PS in mice. BALB/c mice (n= 3 for DH-PS and phosphate
buffered saline (PBS) group) were injected intraperitoneally (IP)
with DH-PS (300 mg/mouse) in PBS or PBS only and the sera
were collected at 0 (before injection), 2 and 18 hrs after the
injection of DH-PS for the detection of cytokines and chemokines,
which were quantified by Beadlyte Mouse 21-plex Cytokine
Detection system and ELISA kits (for IL-1ra). Compared with PBS
group shown in Figure 1, the increase of TNF-a, IL-12 p40, IL-6,
IL-10 and RANTES were observed at 2 hrs, along with robust
inductions of KC, MCP-1 and MIP-1b. An apparent increase in
IL-1b at 2 hrs was noted but it did not reach statistical significance.
These results suggested that DH-PS induced Th1 (IL-12 p40), Th2
(IL-6, IL-10), inflammatory cytokines (TNF-a) and chemokines
(KC, RANTES, MCP-1, MIP-1b), which might further modulate
the downstream activations of immune cells. Furthermore, an antiinflammatory
molecule, IL-1ra, was increased from 465 to
4199 pg/ml (,9 folds of PBS control group) at 2 hrs. This
indicated that the amounts of IL-1ra induced were 10 folds more
than IL-1b (increased from 144 to 397 pg/ml, ,1.6 folds of PBS
control group), suggesting that DH-PS-induced IL-1ra might override
the activity induced by IL-1b.

关于DH-PS在体内诱导多种细胞因子和趋化因子的分泌的研究
为了阐明DH-PS的免疫学活性,我们研究了DH-PS在小鼠体内诱导的细胞因子和趋化因子的特性。BALB/c小鼠(DH-PS磷酸盐缓冲液组,3只)用DH-PS磷酸盐缓冲液(300mg/只)腹腔注射,磷酸盐缓冲液单独注射做对照,并在注射前,注射后2小时、18小时分别取血清,用于检测细胞因子和趋化因子。定量方法为Beadlyte Mouse 21-plex Cytokine Detection system(仪器)和酶联免疫试剂盒。试剂组和对照组的比较见图一,在2小时时,TNF-α,IL-12p40,IL-6,IL-10和RANTES都有增加,而且能够强烈的诱导产生KC,MCP-1和MIP-1等趋化因子。2小时时IL-1b的增加很明显,但并没有达到统计学意义上的显著性差异。这些表明DH-PS能够诱导产生Th1(IL-12p40),Th2(IL-6,IL-10),炎症性细胞因子(TNF-α)和趋化因子(KC,RANTES,MCP-1,MIP-1b)等,而这些因子可能会进一步调节其下游免疫细胞的活性。而且,抗炎分子IL-1ra在2小时的血清含量从465pg/ml增加到4199pg/ml(是对照组的9倍)。这表明诱导产生的IL-1ra的量可能会是IL-1b的10倍之多(IL-1b从144pg/ml增加到397pg/ml,是对照组的1.6倍),预示着DH-ps诱导产生的IL-1ra可能会掩盖IL-1b诱导产生的活性。
