synergistic

"But when the two complex together, you only need very small amounts of each to cause damage. There's a synergistic effect with Aβ and fibrinogen."

To overcome this, the Atukorale Lab has engineered a lipid nanoparticle-based "super adjuvant" capable of stably encapsulating and co-delivering two distinct immune adjuvants that activate immunity in a coordinated, synergistic way.

They are entangled with one another in a synergistic relationship.

Such substances have a “synergistic effect,” he said, and therefore when it comes to pinpointing the cause of the overdose, “it’s not that easy of an equation.”

This discovery points to what's known as a secondary, or synergistic, effect.
