Detailed Immunology Flowchart Creation

I want to turn a complex stretch of immunology concepts into a single, crystal-clear flowchart that undergraduate students can follow without feeling lost. The chart is purely for educational use, so clarity, logical sequencing, and visually distinct pathways are essential. Think of it as the backbone for a lecture slide or study handout: major cells, signaling molecules, and checkpoints laid out step by step, with concise labels that speak the language of students who have had only an introductory course.

I will supply the lecture notes I currently rely on; your task is to distill that content and arrange it visually. Color coding, icons, or any other visual hierarchy that helps learners grasp relationships quickly is welcome, as long as the end result remains clean and printer-friendly.

Deliverables:
• An editable vector file (AI, SVG, or PPT)
• A high-resolution PNG/PDF suitable for print
• A short reference list pinpointing sources for each step

If you have examples of previous scientific infographics, feel free to share them so I can be sure our styles align before we start.
