Alteration of the Vγ2 neg γδ TCR repertoire by malaria infection As a result, this may suggest a role of malaria exposure in altering the Vγ2 neg γδ T cell population. Furthermore, the Vγ2 neg γδ TCR repertoire among Malian children had increased clonotype expansion while exhibiting decreased clonotype diversity and shared sequences. Additionally, the Malian children had increased levels of CD27 lo CX 3CR1 + effector cells, while Australian children had more CD27 hiCX 3CR1 neg naïve cells. Malian and Australian children had a similar Vγ2 + population but differed in the Vγ2 neg T cell population. The analysis of the γδ T cell populations was divided into two groups: Vγ9/Vγ2 + (Vγ2 +) and non-Vγ9/Vγ2 (Vγ2 neg) populations. Comparing the γδ TCR repertoires of Malian children versus Australian children This then begs the question of whether episodes of febrile malaria alter individual γδ T cell clonotypes over time. falciparum transmission, it was found that the Vδ1 effector γδ T cell population expanded after episodes of febrile malaria. While investigating Malian children over 3 malaria seasons with high P. Impact of malaria infection γδ T cell profilesĪdults and children living in locations with high malaria transmission have distinct γδ T cell profiles. 1Here we will discuss his lab’s recently published findings. Martin Davey’s team analyzed the T cell receptor (TCR) repertoire, specifically the repertoire of γδ T cells, using iRepertoire’s human TCRδ and TCRγ iR-Profile Kits. To determine the immune response to Plasmodium falciparum malaria, Dr. There is still much to learn and discover about our complicated immune system however, our knowledge has exponentially improved thanks to next-generation sequencing (NGS). The prospect of overcoming deadly diseases, such as malaria, requires a greater understanding of how our immune system responds to the causative agent.
