Macrophages are cells that play a role in the response of the immune system of mice and other mammals to invasive organisms such as bacteria.

巨噬细胞是在小鼠和其他哺乳动物的免疫系统对细菌等侵入性生物的反应中发挥作用的细胞。

They are reported to serve as biological response modifiers with the capability to activate macrophages and T-cells, and to produce cytokines, interleukins and tumor necrosis factors.

它们被认为是生物反应的调节者，具有有激活巨噬细胞和T细胞的能力，并产生细胞因子、白细胞介素和肿瘤坏死因子。

But unlike the normal mice, those with altered macrophages showed no signs of inflammation, such as changes in insulin production, high levels of immune chemicals, and macrophages in their belly fat.

但与正常小鼠不同，那些使用改变巨噬细胞的表明免疫炎症症状，像在胰岛素产生的变化那样，高水平免疫化学物，和在它们腹部脂肪中的巨噬细胞。

In 1979 pathologist Ross Gerrity showed that in pigs one of the first steps in the formation of artery plaque occurs when macrophages travel into the artery and gobble up cholesterol inside, forming fatty deposits.

FORBES: On The Cover/Top Stories

Over the next decade animal studies at UCLA and elsewhere showed that macrophages are attracted to arteries when cholesterol lodged in the arteries gets chemically altered, or oxidized, so that the immune system suddenly spots it as foreign and goes on the attack.

They found that Salmonella with an inactivated SifA gene no longer has this ability to multiply, and can be killed off by the macrophages.
