Вирус Zika усугубляет энцефаломиэлит, вызывая производство хемокина Т в астроцитах.

Zika virus exacerbates encephalomyelitis by inducing the production of T cell-attracting chemokines in astrocytes.

Recent outbreaks of the ZIKA virus (ZIKV) in Brazil and Puerto Rico have been linked to an increase in the incidence of fetal microcephaly and Guillain-Barré syndrome. In addition, although a causal relationship remains unproven, ZIKV has been found in the brains of multiple sclerosis (MS) patients, prompting interest in a possible link. The present study aimed to elucidate the role of ZIKV in the pathogenesis of MS. ZIKV-infected mice with experimental autoimmune encephalomyelitis (EAE) exhibited aggravated EAE symptoms with significant demyelination of the central nervous system (CNS). Moreover, ZIKV infection promoted pathogenic T cell infiltration into the CNS by enhancing the expression of chemokines for C-C motif chemokine receptor 2 (CCR2) in astrocytes, which was dependent on tumor necrosis factor receptor-associated factor 6 (TRAF6) signaling. Propagermanium, a CCR2 inhibitor, prevented ZIKV-induced exacerbation of EAE in mice. These findings highlight the critical role of TRAF6 signaling in the progression of neurological disorders caused by ZIKV infection.
