Vaccination of interleukin-4 (IL-4) receptor alpha (IL-4Ralpha) chain-deficient BALB/c mice with Helicobacter pylori urease and cholera toxin or with urease-expressing, live attenuated Salmonella enterica serovar Typhimurium cells revealed that protection against H. pylori infection is independent of IL-4- or IL-13-mediated signals. A comparison of male and female mice suggests a sexual dimorphism in the extent of bacterial colonization that is particularly evident in the absence of the IL-4Ralpha chain.
用幽门螺杆菌尿素酶和霍乱毒素或表达尿素酶的减毒活肠炎沙门氏菌血清型鼠伤寒杆菌细胞对白细胞介素-4(IL-4)受体α(IL-4Rα)链缺陷的BALB/c小鼠进行疫苗接种,结果显示,针对幽门螺杆菌感染的保护作用独立于IL-4或IL-13介导的信号。对雄性和雌性小鼠的比较表明,在细菌定植程度上存在性别差异,这在缺乏IL-4Rα链的情况下尤为明显。
