Lesson activities and questions for using ImmuneGuard critically in class.

Educational use · Not a medical device

Lesson guide · Antibody-deficient Host

Teacher Guide: Antibody Deficiency

Humoral deficiency reduces neutralization and opsonization. The impact varies with the antibody component affected, but recurrent infections with encapsulated bacteria are a classic association of significant antibody deficiencies.

View full lesson plan

Learning goals

  • •Demonstrate the importance of humoral immunity
  • •Relate antibody deficiency with recurrent bacterial infections
  • •Explain agammaglobulinemia

Classroom activity

Ask students to activate B cells in this scenario and compare the relative IgG indicator with the standard bacterial scenario. Also compare control time, remembering that simulator values are not laboratory titers.

Discussion questions

  1. 1.Why are antibodies so important for encapsulated bacteria?
  2. 2.How is agammaglobulinemia treated clinically (immunoglobulin replacement)?
  3. 3.What is the difference between antibody deficiency and T cell deficiency?

Lesson guide · Phagocyte-impaired Host

Teacher Guide: Compromised Phagocytes

Deficient phagocytosis leads to chronic inflammation without resolution. Antibodies tag the pathogen, but without eliminating it, the inflammatory cycle persists.

View full lesson plan

Learning goals

  • •Demonstrate the essential role of phagocytes against fungi
  • •Explain chronic granulomatous disease
  • •Visualize chronic inflammation without resolution

Classroom activity

Compare this scenario with the fungal scenario under broad immunosuppression. Ask students to identify when the tissue-damage indicator continues rising despite a reduction in pathogen load. Discuss the inflammatory dilemma.

Discussion questions

  1. 1.Why doesn't the body simply 'stop' inflammation when it causes damage?
  2. 2.What is a granuloma and why does it form in CGD?
  3. 3.How do antifungals work differently from antibiotics?

Lesson guide · T-cell Impaired Host

Teacher Guide: T-cell Deficiency

T cell deficiency impairs elimination of intracellular pathogens and coordination of the adaptive response, leading to persistent infections.

View full lesson plan

Learning goals

  • •Demonstrate the impact of CD4+ and CD8+ deficiency
  • •Connect T cell failure with vulnerability to intracellular pathogens
  • •Discuss diseases like HIV/AIDS

Classroom activity

Compare this scenario with the standard viral infection. Highlight the persistence of infected cells and limited T memory. Introduce the concept of opportunistic infections.

Discussion questions

  1. 1.Why does an HIV patient become susceptible to fungi and herpes viruses?
  2. 2.What does 'opportunistic infection' mean?
  3. 3.How does CD4 count relate to AIDS progression?

Lesson guide · Bacterial Infection

Teacher Guide: Extracellular Bacterial Infection

Extracellular bacterial infections are fought mainly by phagocytes (neutrophils and macrophages) with IgG antibody opsonization. CD8+ T and NK play minimal roles.

View full lesson plan

Learning goals

  • •Understand the role of phagocytes against bacteria
  • •Demonstrate the importance of antibody opsonization
  • •Relate neutrophils to pus formation

Classroom activity

Have students start the scenario with macrophages only, then add antibodies (by activating B cells). Observe how the rate of bacterial clearance increases with opsonization.

Discussion questions

  1. 1.Why do antibiotics work against bacteria but not viruses?
  2. 2.What happens when a patient has low neutrophils (neutropenia)?
  3. 3.What is the relationship between antibodies and phagocytosis?

Lesson guide · Acute Viral Infection

Teacher Guide: Acute Viral Infection

This scenario represents, in simplified form, overlapping phases of antiviral immunity: innate mechanisms act early while the adaptive response develops and expands control of infected cells and free viral particles.

View full lesson plan

Learning goals

  • •Differentiate free viral particles from infected cells
  • •Explain the contribution of CD8+ T and NK cells to antiviral immunity
  • •Interpret viral load, inflammation and damage only as relative model variables

Classroom activity

Ask students to run the scenario twice: once observing automatic recruitment only and once manually mobilizing CD8+ cells. Compare load peaks and control time in the model and discuss the relative contribution of innate and adaptive responses.

Discussion questions

  1. 1.Why do antibodies mainly neutralize free viral particles while infected cells require cellular mechanisms?
  2. 2.How do NK and CD8+ T cells differ in target-cell recognition?
  3. 3.Why can't viral load in this simulator be directly converted into real clinical severity?

Lesson guide · Vaccinated Host

Teacher Guide: Primary vs Secondary Response (Vaccinated)

In this teaching scenario, prior vaccination is represented by immunological memory and pre-existing antibodies. These parameters illustrate a faster secondary response but do not correspond to real vaccine efficacy or laboratory titers.

View full lesson plan

Learning goals

  • •Understand how prior vaccination is represented in the model
  • •Compare relative load peaks with and without pre-existing memory
  • •Connect immunological memory with a faster secondary response

Classroom activity

Run the standard viral and vaccinated scenarios side by side. Record control time, load peak and the relative IgG indicator. Discuss why these values are useful for teaching comparisons but cannot estimate the clinical efficacy of a real vaccine.

Discussion questions

  1. 1.What is the difference between active and passive immunity?
  2. 2.Why do some vaccines require multiple doses or boosters?
  3. 3.ImmuneGuard does not model population transmission: what would need to be added to study herd immunity?

Lesson guide · Cytokine Storm

Teacher Guide: Cytokine Storm

Hyperinflammation demonstrates that tissue damage can be caused by the immune response. The balance between effective and excessive response is fundamental in immunology.

View full lesson plan

Learning goals

  • •Understand that a disproportionate inflammatory response can contribute to tissue damage
  • •Demonstrate hyperinflammation and its effects in the model
  • •Discuss, in an educational context, why controlling inflammation requires balance

Classroom activity

Have students observe the cytokine graph over time. Identify when cytokines exceed the viral load. Discuss the paradox: strong immune response can be harmful.

Discussion questions

  1. 1.How can inflammation contribute to tissue damage even while helping control the pathogen?
  2. 2.Which laboratory markers can be associated with hyperinflammation and why does no single marker define the condition by itself?
  3. 3.Why can anti-inflammatory or immunomodulatory therapies help in some situations and be harmful in others?

Lesson guide · Vaccination and Reinfection

Teacher Guide: Vaccination and Reinfection

Immunological memory allows secondary responses to begin earlier and often reach greater magnitude than primary responses. Memory duration and degree of protection vary by antigen, vaccine and individual.

View full lesson plan

Learning goals

  • •Differentiate primary from secondary response
  • •Understand the biological mechanism of vaccines
  • •Visualize the temporal advantage of immune memory

Classroom activity

Have students complete the basic viral scenario first and record the clearance time. Then activate reinfection and compare the data. Use RoundHistory to visualize the statistical comparison.

Discussion questions

  1. 1.What is the difference between class switching and affinity maturation in the humoral response?
  2. 2.How long can immunological memory last and what factors influence its duration?
  3. 3.How does the simulator represent, in simplified form, the principle behind booster doses?
