In that moment of biting us, the parasite goes from the mosquito, with a temperature at 21°C to 24°C, to the human, at 37°C, and it gets switched on. It has been lying in wait in the salivary glands, and it suddenly arrives in our skin and gets switched on. We started to think how we could generate a whole parasite that looks like it is switched on. That is one of my active research projects. But the second question, which is related, is what the protein surface coat (the aspect of the parasite that the immune system sees) looks like when the parasite is being switched on. Maybe it looks different to the parasite that we have been researching for decades, which is isolated from the mosquito.
