Positive selection:

Which of the following receptor genes are the first to be rearranged in a double negative thymocyte?

T-cells go through somatic recombination in the _____________, and T-cells differentiate into effector cells in the ___________.

Which of the following can be found in the thymus?

Effector T cell homing to inflamed tissue is facilitated by _________ expression on the effector T cell surface.

Both B-cells and T-cells have up to 4 potential attempts to productively rearrange their heavy chain and β-chain genes respectively.

Homing of a naive T cell into a lymph node is initially determined by L-selectin binding to a/an:

T-cells go through somatic recombination in the _____________, and T-cells differentiate into effector cells in the ___________.

Central tolerance for T cells takes place after activation in the bone marrow.

The expression of the pre-T-cell receptor is required in order to halt β-,γ-, and δ-chain rearrangements and induce proliferation of the thymocyte.
