Malaria, caused by infection with Plasmodium parasites, drives multiple regulatory responses across the immune landscape. These regulatory responses help to protect against inflammatory disease but may in some situations hamper the acquisition of adaptive immune responses that clear parasites. In addition, the regulatory responses that occur during Plasmodium infection may negatively affect malaria vaccine efficacy in the most at-risk populations. Here, we discuss the specific cellular mechanisms of immunoregulatory networks that develop during malaria, with a focus on knowledge gained from human studies and studies that involve the main malaria parasite to affect humans, Plasmodium falciparum. Leveraging this knowledge may lead to the development of new therapeutic approaches to increase protective immunity to malaria during infection or after vaccination.
疟疾是由疟原虫感染引起的,它会在整个免疫领域引发多种调节反应。这些调节反应有助于预防炎症性疾病,但在某些情况下,可能会阻碍清除寄生虫的适应性免疫反应的产生。此外,疟疾感染期间发生的调节反应可能会对高危人群的疟疾疫苗效力产生负面影响。在这里,我们讨论了疟疾期间形成的免疫调节网络的特定细胞机制,重点介绍了从人类研究和涉及主要疟原虫(对人类有影响的疟原虫)的研究中获得的知识。利用这些知识可能会开发出新的治疗方法,以在感染期间或接种疫苗后增加对疟疾的保护性免疫。
