In a previous study, it was reported that infection of fibroblasts with Toxoplasma gondii Nicolle and Manceaux, 1908 triggers the production of exosome-like vesicles containing 4 mRNA species with neurological activities including Rab-13, eukaryotic translation elongation factor 1 alpha 1, thymosin beta 4, and LLP homolog, which are suggested to alter brain chemistry to the point of producing behavioral changes, making the exact location of the cells take a backseat as the effect is spread throughout the brain by EVs secretion from infected cells (Pope and Lässer 2013). This evidence concerns the gene TMSB4X and infection.
