Soluble antigen-antibody complexes form in circulation, fail to clear, deposit in vascular walls, and activate complement. This leads to massive neutrophil recruitment and localized tissue destruction.

The complement system consists of a cascade of serum proteins that "complement" the ability of antibodies to clear pathogens. Comprehensive notes map out three distinct pathways that converge on a common terminal pathway:

He wasn't just looking for a file; he was looking for clarity. Dr. Najeeb was the man who could turn a complex intracellular pathway into a campfire story.
