Description

Malaria infection triggers pro-inflammatory responses in humans that are detrimental to host health. Parasite-induced enhancement in cytokine levels correlate with malaria-associated pathologies. Here we show that parasite tyrosyl-tRNA synthetase (PfTyrRS), a housekeeping protein translation enzyme, induces pro-inflammatory responses from host immune cells. PfTyrRS exits from the parasite cytoplasm into the infected red blood cell (iRBC) cytoplasm, from where it is released into the...[Show more]
