Question

Quizplus · Accepted Answer

The first T-cell receptor complex containing the β chain to reach the cell surface during the development of T lymphocytes is the pre-T cell receptor (pre-TCR), which consists of the β chain paired with a surrogate alpha chain called pTα (pre-T alpha), along with the CD3 signaling complex. This configuration is essential for the progression of T cell development in the thymus.
