黄病毒对全球健康构成越来越大的威胁,它们有可能在数百万人中引起严重疾病。保护性和长期免疫与CD4 T细胞的产生密切相关,CD4 T细胞提供B细胞帮助并支持高亲和力中和抗体应答。在过去几年中进行的研究揭示了重要的新见解的抗原特异性和不同的效应功能的CD4 T细胞对黄病毒的反应。此外,参与调节T细胞特异性和功能的机制的鉴定为我们理解如何建立持久的保护性免疫提供了重大进展。在这里,我们总结了什么是已知的人CD4 T细胞对黄病毒的反应,特别强调CD4 T细胞,提供直接帮助B细胞产生中和和保护性抗体。我们回顾了在黄病毒蛋白的原子结构背景下识别表位位点的最新进展,并强调了在感染或疫苗接种的背景下塑造人CD4 T细胞应答的特定影响。最后,我们讨论了疫苗努力产生适当的CD4 T细胞反应所面临的挑战,以及最近的策略,以提高T细胞介导的抗体反应。
Flaviviruses pose an increasing threat to global health with their potential to cause severe disease in millions of people. Protective and long-lived immunity is closely linked to the generation of CD4 T cells, which provide B cell help and support high affinity neutralizing antibody responses. Research performed during the last years revealed important new insights into the antigen specificities and diverse effector functions of CD4 T cell responses to flaviviruses. Moreover, the identification of mechanisms involved in the regulation of T cell specificity and function provides significant advances in our understanding of how durable protective immunity is established. Here, we summarize what is known about human CD4 T cell responses to flaviviruses, with a special emphasis on CD4 T cells that provide direct help to B cells producing neutralizing and protective antibodies. We review recent progress in the identification of epitope sites in the context of the atomic structures of flavivirus proteins and highlight specific influences that shape the human CD4 T cell response in the context of infection or vaccination. Finally, we discuss challenges facing vaccine efforts to generate appropriate CD4 T cell responses, as well as recent strategies to enhance T cell-mediated antibody responses.
