Among the symptoms of SARS-CoV-2, follicular conjunctivitis has become relevant. The conjunctiva acts as an open lymph node, reacting to the viral antigen that binds the epithelial cells, forming follicles of B cells with activated T cells and NK cells on its surface, which, in turn, talk to monocyte-derived inflammatory infected macrophages. Here, the NLRP3 inflammasome is a major driver in releasing pro-inflammatory factors such as IL-6 and caspase-1, leading to follicular conjunctivitis and bulbar congestion, even as isolated signs in the 'asymptomatic' patient.
在新型冠状病毒肺炎（SARS-CoV-2）的症状中，滤泡性结膜炎已变得较为常见。结膜起着开放淋巴结的作用，对与上皮细胞结合的病毒抗原作出反应，在其表面形成含有活化T细胞和自然杀伤（NK）细胞的B细胞滤泡，而这些细胞又与单核细胞衍生的炎性感染巨噬细胞相互作用。在此，NLRP3炎性小体是释放白细胞介素-6（IL-6）和半胱天冬酶-1等促炎因子的主要驱动因素，可导致滤泡性结膜炎和球结膜充血，甚至在“无症状”患者中也可作为单独的体征出现。
