Division and adaptation to host nutritional environment of apicomplexan parasites depend on apicoplast lipid metabolic plasticity and host organelles remodelling

N. J. Katris, S. Amiar, L. Berry, S. Dass, M. J. Shears, C. Brunet, B. Touquet, M.-A. Hakimi, G. I. McFadden, Y. Yamaryo-Botte, C. Y. Botte

This study shows that apicomplexan parasites adapt to host nutritional changes by shifting lipid acquisition between de novo synthesis and host scavenging, involving apicoplast lipid metabolism and host organelle remodeling.

Calcium negatively regulates secretion from dense granules in Toxoplasma gondii.

N. J. Katris, G. I. McFadden, G. G. van Dooren, R. F. Waller

This study shows that calcium negatively regulates dense granule exocytosis in Toxoplasma gondii, dependent on calcium-dependent protein kinases TgCDPK1 and TgCDPK3.

Protein Kinase A Negatively Regulates Ca2+ signalling in Toxoplasma gondii

A. D. Uboldi, M.-L. Wilde, E. A. McRae, R. J. Stewart, L. F. Dagley, L. Yang, N. J. Katris, S. V. Hapuarachchi, M. J. Coffey, A. M. Lehane, C. Y. Botte, R. F. Waller, A. I. Webb, C. J. Tonkin

This study shows that Protein Kinase A (PKAc1) suppresses Ca2+ signalling in Toxoplasma gondii after host cell invasion, affecting motility and infectivity.
