Expression of D₁ and D₂ dopamine receptors in Normal and Jurkat cells. A, semiquantitative reverse transcription-polymerase chain reaction analysis of mRNA shows presence of D₁ and D₂ dopamine receptor expression in normal activated T cells and Jurkat cells. 15 S rRNA expression is the positive control. B, Western blot with specific antibodies against receptors also revealed similar expression pattern of D₁ and D₂ dopamine receptor proteins in normal and Jurkat T lymphocytes. Results are representative of six separate experiments.
