These findings with mice indicate that progesterone may have minimal effects on the responses to specific parasite threat and the expression of pathogen disgust but may influence more general social recognition and preferences.Saxitoxins (STXs) are neurotoxins produced by cyanobacteria and dinoflagellates, and they are primarily known to block voltage-gated sodium channels in neurons. The present study aimed to obtain further information regarding the effects of these toxins on neurodevelopment by investigating the responses of murine subventricular zone (SVZ) neural progenitors to STXs. An in vitro neonatal mouse SVZ explant model was exposed to different concentrations of toxic cyanobacterial extracts to evaluate the migration and differentiation of SVZ-derived progenitor cells. To test the ability of STX to cross the placental barrier, pregnant mice received a single intraperitoneal injection of STXs (7.5 μg/kg body weight) on gestational day fifteen. Immunocytochemistry was performed to detect proliferating and differentiating progenitors, including oligodendrocyte progenitor cells (OPCs). It was found that specific proliferation of OPCs was significantly increased, but there was no corresponding increase in the number of differentiated oligodendrocytes, which may indicate a negative effect on the maturation process of these cells. Additionally, the data showed that STXs crossed the placental barrier. Thus, STXs can be considered a potential risk to fetal neurodevelopment.The OX40 receptor plays a crucial co-stimulatory role in T effector cell survival, expansion, cytokine production, and cytotoxicity to tumor cells; therefore, OX40 agonists are being evaluated as anti-cancer immunotherapies, especially in combinatio
