The study included 200 healthy age and sex matched controls (120 healthy volunteers and 80 healthy antenatal cases without any bad obstetric history) and 300 cases comprising patients with bad obstetric history (BOH) 80 cases, seizure or encephalitis 50 cases, cervical lymphadenopathy 30 cases, congenital deformity 30 cases, HIV infected 80 cases and patients on long term immunosuppression 30 cases. Anti-toxoplasma IgG & IgM were measured by ELISA and individuals found positive for anti Toxoplasma gondii IgM or with high titre of IgG were subjected to repeat testing after 3 weeks for rise in titre. True sero-prevalence of T gondii infection was found to be 19% and it increased with increasing age in the population. 2.33% patients were found to have acute toxoplasma infection. Statistical significance was seen only in patients with BOH and children born with congenital abnormality.

chitinase-like protein orchestrates cyst wall glycosylation to facilitate effector export and cyst turnover.

bradyzoites reside in tissue cysts that undergo cycles of expansion, rupture, and release to foster chronic infection. The glycosylated cyst wall acts as a protective barrier, although the processes responsible for formation, remodeling, and turnover are not understood. Herein, we identify a noncanonical chitinase-like enzyme TgCLP1 that localizes to micronemes and is targeted to the cyst wall after secretion.

Glycolysis is a conserved metabolic pathway that converts glucose into pyruvate in the cytosol, producing ATP and NADH. In and several other apicomplexan parasites, some glycolytic enzymes have isoforms located in their plastid (called the apicoplast). In this organelle, glycolytic intermediates like glyceraldehyde 3-phosphate (GAP) and dihydroxyacetone phosphate (DHAP) are imported from the cytosol and further metabolized, providing ATP, reducing power, and precursors for anabolic pathways such as isoprenoid synthesis.

The intracellular protozoan Toxoplasma gondii manipulates host cell signaling to avoid targeting by autophagosomes and lysosomal degradation. Epidermal Growth Factor Receptor (EGFR) is a mediator of this survival strategy. However, EGFR expression is limited in the brain and retina, organs affected in toxoplasmosis.
View Article and Find Full Text PDFMany inflammatory stimuli can induce progenitor cells in the bone marrow to produce increased numbers of myeloid cells as part of the process of emergency myelopoiesis. These events are associated with innate training and can have long-term impacts on hematopoietic stem and progenitor cell (HSPC) development but can also compromise their function. While many cytokines support emergency myelopoiesis, less is known about the mechanisms that temper these events.
