The GPI sidechain of Toxoplasma gondii prevents parasite pathogenesis

J. A. Alvarez, E. Gas-Pascual, S. Malhi, F. N. Njume, J. C. Sanchez-Arcila, H. van der Wel, Y. Zhao, G. Ceron, J. Posada, S. P. Souza, G. S. Yap, C. West, K. D. C. Jensen

This paper identifies and characterizes glycosyltransferases in Toxoplasma gondii that modify GPI sidechains, showing that their absence increases parasite virulence.

IFNγ and acute prenatal infection with Toxoplasma gondii activate fetal hematopoietic stem cells

D. A. Lopez, K. S. Otsuka, A. C. Apostol, J. Posada, J. C. Sanchez-Arcila, K. D. Jensen, A. E. Beaudin

This study shows that maternal IFNγ and T. gondii infection alter fetal HSC proliferation, self-renewal, and lineage output, with IFNγ mimicking some infection effects.
