Interplay between the heterotrimeric G-protein subunits G<sub>αq </sub>and G<sub>αi2 </sub>sets the threshold for chemotaxis and TCR activation

<p>Abstract</p> <p>Background</p> <p>TCR and CXCR4-mediated signaling appears to be reciprocally regulated pathways. TCR activation dampens the chemotactic response towards the CXCR4 ligand CXCL12, while T cells exposed to CXCL12 are less prone to subsequent TCR-activat...
