The Short Answer

It seems to be linked to the nervous response. There are a number of different ideas out there. One claims that it's a process of denaturing proteins that would cause the itch. But that explanation wouldn't portray very good proteins. We would have proteins failing every time we take a shower. Another claims that it somehow "cancels" the mosquito saliva. But by that point the anti-coagulants injected by the mosquito are no where near the surface of your skin. The most reasonable hypothesis is that it confuses or overloads your nervous system. Instead of sending a signal for 'itch', your neurons send the signal for 'warmth' or for 'pain'. So it's probably that it messes with your nerves a bit.
