I am analysing this picture about acute hepatitis, viral infection of HBV, where are standard antibodies and antigens of HBV:
- HBsAg serum antigen
- HBeAg some antigen in blood
- anti-HBc antibody in blood
- IgM and IgG are immunoglobulins for antibodies HBc as diagnostic tests
The curve Anti-HBc intersects with HBeAg and starts symptoms. I am interested what this intersection mean. Can you think it as analogue to heart's valves and pressure? The amount of Anti-HBc becomes more than HBeAg which exposes the Anti-HBc to some cells. When HBeA then intersects with level of detection (no more HBeAg in blood), so the exposure of Anti-HBc to cells ends and symptoms end. HBeAg seems to be analogously like a key to symptoms.
How do you interpret the intersections of these two curves?
