用重组水痘带状疱疹病毒(VZV)糖蛋白E (gE)和I (gI)免疫的豚鼠在血清、玻璃体和结膜洗液中产生抗原特异性抗体。免疫动物的血清中和了无细胞和细胞相关的VZV,并且外周血淋巴细胞在体外对重组gE和gI以及来自VZV感染细胞的抗原作出反应而增殖。免疫后的豚鼠玻璃体内接种VZV,诱导慢性葡萄膜炎。与单独接种佐剂的对照组相比,接种gE和gI的动物视网膜中VZV DNA的清除速度更快,传染性VZV的分离频率更低。尽管如此,在接种VZV后21天,在佐剂单独和ge - gi免疫的动物中,玻璃体、视网膜和脉络膜的细胞浸润都很普遍。免疫VZV gE和gI诱导了有效的体液和细胞反应,加速了VZV DNA的清除,并可能在眼内中和病毒。
Guinea pigs immunized with recombinant varicella-zoster virus (VZV) glycoproteins E (gE) and I (gI) developed antigen-specific antibodies in the sera, vitreous, and conjunctival washes. Sera from immunized animals neutralized both cell-free and cell-associated VZV, and peripheral blood lymphocytes proliferated in vitro in response to recombinant gE and gI and to antigens from VZV-infected cells. Immunized guinea pigs were inoculated intravitreally with VZV, which induces chronic uveitis. VZV DNA was more rapidly cleared and infectious VZV was isolated less frequently from the retinas of animals immunized with gE and gI compared with that in controls receiving adjuvant alone. Nonetheless, cellular infiltrates in the vitreous, retina, and choroid were prevalent 21 days after VZV inoculation in both the adjuvant-alone- and gE-gI-immunized animals. Immunization with VZV gE and gI induced potent humoral and cellular responses that accelerated the clearance of VZV DNA and may neutralize virus within the eye.
