This study examines the production of superoxide (O2-) as a response to various concentrations of fMLF and PMA over time. Utilizing a series of experiments, we quantified O2- production in percentage and measured cellular responses under different conditions, including control and PTX treatments. The findings contribute valuable insights into the signaling pathways activated by these agonists, and how they influence reactive oxygen species production in immune cells. Data are presented for time points and concentration variations of stimulants.
