Forward genetics is a powerful approach to identify genes in intracellular pathogens important for resistance to cell autonomous immunity. The current approach uses innate immune cells, specifically macrophages, to identify novel Toxoplasma gondii genes important for immune evasion.
Overview
This study utilizes forward genetics to identify genes in Toxoplasma gondii that are crucial for evading cell autonomous immunity in macrophages. By focusing on innate immune cells, the research aims to uncover novel mechanisms of immune evasion by this intracellular pathogen.
