Abstract | The physiological and molecular responses of leukocytes are altered by organophosphate pesticides (OPs). Some reports have shown that diazinon (DZN) causes immunotoxic effects; diazoxon (DZO), the oxon metabolite of DZN, is attributed to influence the immune response by affecting the leukocyte cholinergic system. In this study, the in vitro effects of DZO on molecules involved in cell signaling (cAMP, IP3, DAG, JAK1, and STAT3), which play a crucial role in the activation, differentiation, and survival of leukocytes, were evaluated. Data indicate that DZO leads to a decrease in cAMP concentration and an increase in basal IP3 levels. However, DZO does not affect basal levels of JAK1 and STAT3 phosphorylation. Instead, DZO inhibits leukocyte responsiveness to PMA and ionomycin, substances that, under normal conditions, enhance JAK/STAT signaling. These findings demonstrate that DZO significantly affects key molecular parameters related to cell signaling. |
