What do StepGenie's immunology images cover?
Each immunology image is a StepGenie infographic drawn for one of its own practice questions. Most place a defect at a specific point in the immune response — a missing cell, a missing enzyme, a misdirected antibody — and then show what that predicts clinically.
Autoimmune disease and vasculitis form the largest group here, then immunodeficiency syndromes, allergic reactions and anaphylaxis, and hypersensitivity responses, with smaller sets on cell-mediated and humoral immunity and on the immune mechanisms behind glomerular and pulmonary disease.
Immunodeficiency is one of the few topics where a mechanism diagram is strictly better than a mnemonic. A panel that places the block on the maturation pathway explains the infections a patient gets without asking you to remember the pairing separately, and the same panel then explains the vaccine that is contraindicated. The hypersensitivity images do similar work: they hold all four types on one axis so a new example can be sorted by its timing and its mediator.
Because immunology overlaps everything, several of these images also appear under infectious disease and rheumatology. That repetition is intentional — the same picture answers questions filed under different systems.
Transplant rejection is a small but distinct group. Those panels sort hyperacute, acute and chronic rejection by the time they appear and by the mechanism behind each, which is what keeps the three apart under exam conditions.
Topics in this set
Labels are the question-bank topics these images are filed under. Step 1 and Step 2 file some of the same material under different names, so a few labels here merge both.
