免疫记忆为之前通过感染或疫苗接种遇到的病原体提供快速保护。 CD4 T 细胞在所有适应性免疫反应中发挥着核心作用。因此,疫苗如果要产生保护性免疫力,就必须激活 CD4 T 细胞。对于许多疾病,我们没有有效的疫苗。其中包括人类免疫缺陷病毒(HIV)、结核病和疟疾,这些疾病每年导致全球数百万人死亡。 CD4 T 细胞在免疫反应过程中发挥着许多不同的作用,协调许多其他细胞的行动。为了利用记忆 CD4 T 细胞的多种保护作用,我们需要了解记忆 CD4 T 细胞是如何产生的以及它们如何保护宿主。在这里,我们回顾了关于外周组织(组织驻留记忆 T 细胞)和循环(中枢和效应记忆 T 细胞)中发现的不同记忆 CD4 T 细胞亚群位置的最新发现。我们讨论这些细胞的产生,以及证明它们如何在动物和人类挑战模型中提供免疫保护的证据。
Immunological memory provides rapid protection to pathogens previously encountered through infection or vaccination. CD4 T‐cells play a central role in all adaptive immune responses. Vaccines must, therefore, activate CD4 T‐cells if they are to generate protective immunity. For many diseases, we do not have effective vaccines. These include human immunodeficiency virus (HIV), tuberculosis and malaria, which are responsible for many millions of deaths each year across the globe. CD4 T‐cells play many different roles during the immune response coordinating the actions of many other cells. In order to harness the diverse protective effects of memory CD4 T‐cells, we need to understand how memory CD4 T‐cells are generated and how they protect the host. Here we review recent findings on the location of different subsets of memory CD4 T‐cells that are found in peripheral tissues (tissue resident memory T‐cells) and in the circulation (central and effector memory T‐cells). We discuss the generation of these cells, and the evidence that demonstrates how they provide immune protection in animal and human challenge models.
