Cysteine-S-nitrosylation inhibits Rop5-mediated immune evasion in Toxoplasma gondii

Samantha L. Lempke, P. DiMare, B. Nichols, L. F. Fitzsimmons, A. Chaudhry, V. C. Grebe, Michael L. Reese, Sarah E. Ewald

This study shows that RNS inhibit ROP5-mediated immune evasion in Toxoplasma gondii by modifying ROP5 through S-nitrosylation, reducing its association with the parasitophorous vacuole membrane.
