Unravelling the mechanisms of neurological damage during cryptococcal infection of the brain
Project disclaimer
Description
MRC ARL award, This research will fill the existing knowledge gap on how the brain is injured in cryptococcal meningitis. This models and methods would then serve as a platform for studying the mechanisms of other infections of the Central Nervous System that are caused by bacteria, parasites and viruses to inform the development of the much-needed new therapies.
Objectives
AIM 1: Determine the neuroimmune response of microglia and neurons to C. neoformans Objective 1.1: Characterise neuroimmune signalling pathways in microglial cells during C. neoformans infection Objective 1.2: Characterise the mechanisms and effects of neuronal invasion by C. neoformans Objective 1.3: Characterise cell-type specific gene expression during C. neoformans infection in organotypic slices using single-nucleus RNA sequencing AIM 2: Investigate the effect of cryptococcal entry and accumulation in brain compartments on fluid flow and neuroimmune homeostasis Objective 2.1: A spatiotemporal anatomopathological characterisation of cryptococcal infection of the mouse and human brain Objective 2.2: An investigation of the effect of cryptococcal infection on fluid transport in a mouse model of CM Objective 2.3: Characterise spatial gene expression profiles during C. neoformans infection in an in vivo rodent model of CM using spatial transcriptomic sequencing
