Asexual expansion of Toxoplasma gondii merozoites is distinct from tachyzoites and entails expression of non-overlapping gene families to attach, invade, and replicate within feline enterocytes

Abstract: BackgroundThe apicomplexan parasite Toxoplasma gondii is cosmopolitan in nature, largely as a result of its highly flexible life cycle. Felids are its only definitive hosts and a wide range of mammals and birds serve as intermediate hosts. The latent bradyzoite stage is orally infectious in all warm-blooded vertebrates and establishes chronic, transmissible infections. When bradyzoites are ingested by felids, they transform into merozoites in enterocytes and expand asexually as part of their coccidian life cyc… Show more

“…The lack of a tissue culture model for studying the sexual development of T. gondii has caused a dearth in molecular analyses of the parasite. Recently, the application of RNA sequencing technology (RNA-seq) of infected feline tissues has allowed the first transcriptome analyses of the sexual stages (21). Further RNA-seq of infected feline epithelial cells as well as the development of a stable feline intestinal epithelial cell line will be necessary to address the many questions surrounding T. gondii sexual development.…”

“…A partir destes resultados houve a percepção de que a superfície deste Apicomplexa era consideravelmente mais complexa do que se imaginava (JUNG et al, 2004;WASMUTH et al, 2012). A combinação deste estudo com outras pesquisas de sequências expressas em um banco de dados de Toxoplasma gondii (EST) (KISSINGER et al, 2003), revelou não só a presença de ortólogos SRS em outros gêneros coccidianos, incluindo Neospora e Sarcocystis (HOWE et al, 1998(HOWE et al, , 2008REID et al, 2012;WASMUTH et al, 2012), como também níveis de expressão relativa e distribuição dessas proteínas SRSs entre diferentes formas evolutivas de T. gondii HEHL et al, 2015). (HEHL et al, 2015).…”

(HEHL et al, 2015). Embora a função precisa desta superfamília de proteínas de superfície ainda continue desconhecida, sabe-se que as proteínas SRS estão envolvidas na adesão a célula hospedeira, mas que também provocam reações imunes e regulam a virulência do parasita (HEHL et al, 2015).…”
