Two Distinct Lineages of T Cells Can Be Identified Based $\alpha$

Multiple Choice

Two distinct lineages of T cells can be identified based on their expression of $\alpha$ : $\beta$ versus $\gamma$ : $\delta$ T-cell receptors. A deficiency in the signaling receptor Notch1 would result in:

A) A loss of $\alpha$ : $\beta$ but not $\gamma$ : $\delta$ T cells
B) A loss of both of $\alpha$ : $\beta$ and $\gamma$ : $\delta$ T cells
C) A loss of $\alpha$ : $\beta$ T cells and a massive expansion of $\gamma$ : $\delta$ T cells
D) An increased number of both of $\alpha$ : $\beta$ and $\gamma$ : $\delta$ T cells
E) A normal number of both of $\alpha$ : $\beta$ and $\gamma$ : $\delta$ T cells
