It's been an interesting group. Most days we start seven or eight freshmen. They've handled situations pretty well, and we also have pretty good leadership from our sophomore class.

What I've tried to tell them is that it's an acknowledgement of their hard work, but not to let it go to their heads. They still have to go out and work hard every single day in order to maintain it.

This team has great team chemistry. We are very young, predominantly freshmen. But our sophomores have good leadership skills and the players respect one another and work together for the same goal.

You bring in freshman and you know they have the talent to do it. On the field, there's not much that distracts them. They have the right focus.

In addition to the physical contact, it surprised us to find that these immune cells also have machinery to take up serotonin and to secrete it in an excitatory manner. The point behind this transmission is not entirely clear, but it appears to be an additional way of stimulating a T cell response.

The novelty is that we reveal a potential communication, involving the transmitter serotonin, between immune cells that is normally only found between neurons.
