We report that freshly isolated, unstimulated Kupffer cells (KC) from MRL/lpr female mice in short-term culture spontaneously produce high levels of TNF-alpha. TNF production was first detected in KC cultures at age 6 wk and increased with the age of the mice. Moreover, the levels of spontaneous TNF production by KC directly correlated with the age of the MRL/lpr mice. Although TNF production by KC could be induced with C. parvum in vivo or LPS in vitro in all nonautoimmune C3H/HeN, BALB/c, DBA/2, C57B16 mice, the only other strain in which spontaneous TNF production by KC was observed was MRL/++ mice greater than 10 mo old.
我们报告称,从MRL/lpr雌性小鼠新鲜分离的未受刺激的库普弗细胞(KC)在短期培养中会自发产生高水平的肿瘤坏死因子-α(TNF-α)。TNF的产生在6周龄的KC培养物中首次被检测到,并随着小鼠年龄的增长而增加。此外,KC自发产生TNF的水平与MRL/lpr小鼠的年龄直接相关。虽然在所有非自身免疫性的C3H/HeN、BALB/c、DBA/2、C57B16小鼠中,KC产生TNF可在体内被微小隐孢子虫诱导或在体外被脂多糖诱导,但观察到KC自发产生TNF的唯一其他品系是大于10月龄的MRL/++小鼠。
