In EM cells, SLP-76, LAT, PI3K, and c-Cbl expression are coregulated. (A) Correlation of the expression of SLP-76, LAT, PI3K with c-Cbl in 8 to 10 distinct subjects. The significance of their linear correlation is shown (Pearson r and P < .05). (B) Correlation of the expression of TCR/CD3 ϵ and ζ components as described for panel A.
