Model of Pru p 3 induced mast cell (MC) activation in patients with LTP mono-sensitization (left) and patients co-sensitized to unrelated allergens (right), e.g., from birch pollen or the same source (profilin and Bet v 1-like protein). Due to the high density of LTP-specific IgE on the surface of MC in LTP mono-sensitized patients, Pru p 3 efficiently induces mediator release which corresponds with a higher probability of severe reactions
