Medical School MD + DO Mastery

A 4-year, board-aligned study system for medical school and licensing exams.

Walk the full Year 1–4 curriculum — foundational sciences, organ-system blocks, clinical clerkships and advanced practice — each with mastery checklists and linked learning resources, plus a dedicated review system for school exams, Shelf/COMAT, USMLE Step 1–3 and COMLEX-USA Levels 1–3.

IMMUNOLOGY REVIEW MASTERY

YEAR 1 | PAGE 43B - IMMUNE FUNCTION, HYPERSENSITIVITY + IMMUNODEFICIENCY

IMMUNE MODEL: BARRIER / PATTERN RECOGNITION -> INFLAMMATION + COMPLEMENT -> ANTIGEN PRESENTATION -> T/B-CELL ACTIVATION -> EFFECTOR RESPONSE -> MEMORY / TOLERANCE. CLASSIFY BY FUNCTION BEFORE MEMORIZING NAMES. D. IMMUNOLOGY REVIEW MAP

DomainMust retrieve without notesApplication
Innate immunityBarriers; PRRs/TLRs; neutrophils/macrophages; NK cells; complement; inflammatory mediators.Predict the consequence of losing recognition, opsonization, chemotaxis or phagocyte killing.
Adaptive immunityMHC I/II; APCs; CD4/CD8; B-cell activation; antibody isotypes; class switching; memory.Move from antigen location -> presentation pathway -> effector arm -> expected pathogen/tissue consequence.
Hypersensitivity / autoimmunityTypes I-IV; tolerance; receptor antibody vs immune complex vs T-cell injury.Classify by effector + timing + tissue-injury mechanism before naming the disease.
ImmunodeficiencyComplement, phagocyte, B-cell, T-cell and combined defects; age, organisms, labs, syndromic clues.Infer missing immune function from infection pattern rather than recalling eponyms first.
Transplant / immunotherapyHyperacute/acute/chronic rejection; GVHD; biologic targets; immune adverse effects.Use mechanism, timing and target cell/antibody to distinguish rejection and treatment consequences.

Complement Proteins - Ninja Nerd - classical, lectin and alternative pathways; C3/C5 and MAC. Adaptive Immunity - Ninja Nerd - APCs, helper/cytotoxic T cells, B cells and memory. T-Cell Development - Ninja Nerd - positive/negative selection and central tolerance. Approach to Primary Immunodeficiencies - Osmosis - age, organism pattern and immune-compartment framework. Chediak-Higashi vs CGD vs LAD vs Wiskott-Aldrich - Dirty Medicine - board-style discrimination of recurrent immunodeficiency patterns.

CLASSIFY BY FUNCTION BEFORE MEMORIZING NAMES. D. IMMUNOLOGY REVIEW MAP — F. TOP 10 MOST-MISSED CONCEPTS - #4 TO #6 4. Immune molecules are best learned by job, source and consequence Deep explanation

Cells, cytokines, antibodies and complement proteins form a functional network. For each molecule, know who makes it, the trigger, the target and what function is gained or lost.

Why learners miss itLong cytokine and CD-marker lists create recognition but not mechanism-based retrieval.

Immune molecules are best learned by job, source and consequence Deep explanation

Easiest clueWho makes it -> who receives it -> what changes? That triad is more durable than a list.
5. Antigen location determines MHC pathway and T-cell response Deep explanationEndogenous/cytosolic antigen is generally presented on MHC I to CD8 cells; exogenous/phagocytosed antigen is generally presented on MHC II to CD4 cells. This connects infection type to effector response.
Why learners miss it Easiest clueMHC numbers and CD numbers are memorized as pairings without understanding why the pairing exists. Inside the cell -> I -> CD8; outside/phagocytosed -> II -> CD4. Start with antigen location.
6. Immunodeficiency is an infection-pattern localization problem Deep explanationRecurrent organism class, age of onset, absent tissue structures, vaccine reactions and basic blood-cell/immunoglobulin data localize the missing immune arm before the syndrome name.
Why learners miss it Easiest clueClassic eponyms dominate memory and fail when the vignette omits the hallmark association. Organism pattern -> immune function -> syndrome. Localize the missing defense first.
