GCN5a is a telomeric lysine acetyltransferase whose loss primes Toxoplasma gondii for latency

Vishakha Dey, Michael J. Holmes, Sandeep Srivastava, Emma H. Wilson et autres

ABSTRACT Toxoplasma gondii is a protozoan parasite that causes persistent infection in warm-blooded vertebrates by undergoing differentiation from a replicative stage (tachyzoites) to a latent encysted stage (bradyzoites). Stage differentiation is critical for transmission and pathogenesis and relies on gene regulation driven …

Effects of acute selective cyclooxygenase‐2 inhibition on skeletal muscle microvascular oxygenation and exercise tolerance

Michael D. Belbis, Michael J. Holmes, Joseph D. Yao, Christopher W. Kinnick et autres

Abstract The cyclooxygenase (COX) pathway regulates vascular tone and, therefore, local O 2 delivery‐utilization matching. The two main isoforms, COX‐1 and COX‐2, may promote opposing effects on contracting muscle O 2 transport in health by inducing vasoconstriction and vasodilatation, respectively. Whether COX‐2 …

Cap-independent translation directs stress-induced differentiation of the protozoan parasite Toxoplasma gondii

Vishakha Dey, Michael J. Holmes, Matheus Silva e Bastos, Ronald C. Wek et autres

Translational control mechanisms modulate the microbial latency of eukaryotic pathogens, enabling them to evade immunity and drug treatments. The protozoan parasite Toxoplasma gondii persists in hosts by differentiating from proliferative tachyzoites to latent bradyzoites, which are housed inside tissue cysts. Transcriptional changes …

Translation initiation factor eIF1.2 promotes Toxoplasma stage conversion by regulating levels of key differentiation factors

Feng‐Rong Wang, Michael J. Holmes, Hea Jin Hong, Pariyamon Thaprawat et autres

The parasite Toxoplasma gondii persists in its hosts by converting from replicating tachyzoites to latent bradyzoites housed in tissue cysts. The molecular mechanisms that mediate T. gondii differentiation remain poorly understood. Through a mutagenesis screen, we identified translation initiation factor eIF1.2 as …

mRNA cap-binding protein eIF4E1 is a novel regulator of Toxoplasma gondii latency

Michael J. Holmes, Matheus Silva e Bastos, Vishakha Dey, Vanessa Rossini Severo et autres

ABSTRACT The protozoan parasite Toxoplasma gondii causes serious opportunistic disease due to its ability to persist in patients as latent tissue cysts. The molecular mechanisms coordinating conversion between proliferative parasites (tachyzoites) and latent cysts (bradyzoites) are not fully understood. We previously showed …

Abstract The protozoan parasite Toxoplasma gondii causes serious opportunistic disease due to its ability to persist in patients as latent tissue cysts. The molecular mechanisms coordinating conversion between proliferative parasites (tachyzoites) and dormant cysts (bradyzoites) are not fully understood. We previously showed …

A transcriptional network required for bradyzoite development in Toxoplasma gondii is dispensable for recrudescent disease

Sarah L. Sokol-Borrelli, Sarah M. Reilly, Michael J. Holmes, Stephanie B. Orchanian et autres

Identification of regulators of Toxoplasma gondii bradyzoite development and cyst formation is the most direct way to address the importance of parasite development in long-term persistence and reactivation of this parasite. Here we show that a T. gondii gene (named Regulator of …

Toxoplasma gondii AP2XII-2 Contributes to Transcriptional Repression for Sexual Commitment

Sandeep Srivastava, Michael J. Holmes, Michael W. White, William J. Sullivan

Toxoplasma gondii is a parasite that undergoes its sexual stage exclusively in feline intestines, making cats a major source of transmission. A better understanding of the proteins controlling the parasite's life cycle stage transitions is needed for the development of new therapies …
