Hello! I'm your ImmunoAI Tutor. Ask me anything about immunology — from basic concepts like innate immunity to advanced topics like complement activation or T-cell signaling pathways. What would you like to learn today?

What is the difference between T helper 1 and T helper 2 cells?

Th1 cells produce IFN-γ and IL-2, promoting cell-mediated immunity against intracellular pathogens. Th2 cells produce IL-4, IL-5, and IL-13, driving humoral immunity and IgE production — important in allergies and parasitic infections. The balance between Th1/Th2 determines disease outcome. 🔬

Explain the Classical Complement Pathway

The Classical Pathway is activated by antigen-antibody complexes (IgG/IgM). C1q binds to Fc regions → activates C1r and C1s → cleaves C4 and C2 → forms C3 convertase (C4b2a) → amplifies complement cascade → ultimately forms MAC (C5b-9) causing cell lysis. 💊
