Project description:Naturally-acquired immunity to blood-stage malaria is associated with several effector CD4 + T subsets including germinal centre (GC) Tfh, Th1 and Tr1 cells. Here, we mapped the locations of effector CD4+ T cell subsets during post-Plasmodium convalescence using Slide-seqV2.
Project description:Blood-stage malaria infection induces differentiation of several effector CD4 + T subsets including Tfh and Th1 cells. The cues and microarchitectural niches required in secondary lymphoid organs for their formation were previously uncharacterised. Here we used spatial transcriptomics to characterise the microarchitecture of mouse spleen before and during malaria infection, and mapping the spatial and molecular requirements of Tfh/Th1 differentiation.
Project description:These data were used in the spatial transcriptomics analysis of the article titled \\"Single-Cell and Spatial Transcriptomics Analysis of Human Adrenal Aging\\".

Project description:To investigate spatial heterogeneities in the axolotl forebrain, a coronal section of it was obtained for spatial transcriptomics using Visium V1.
Project description:During liver infection, the malaria parasite undergoes massive replication whilst remaining clinically silent. Spatial coordination of immune response regulation and metabolic zonation during malaria infection in the true tissue context remains unexplored. We perform spatial transcriptomics combined with snRNA-seq over multiple time points to delineate transcriptional programs of host-pathogen interactions across P. berghei-infected liver tissues. Our data suggest changes in gene expression related to lipid metabolism adjacent to infected hepatocytes, particularly modulation of the expression of genes involved in peroxisome proliferator-activated receptor pathway signaling. The data further indicates the presence of inflammatory hotspots with differential inflammation programs along the lobular axis in infected tissues. Additionally, upregulation of genes involved in inflammation is observed, but considerably delayed, in livers of control mice injected with mosquito salivary gland components. Our study establishes a benchmark for investigating host-parasite interactions, and can easily be implemented to validate de novo malaria drug and vaccine efforts.
