Identification of transcription start sites and preferential expression of select CB2 transcripts in mouse and human B lymphocytes.

ABSTRACT: Marijuana cannabinoids, the endocannabinoids, and cannabinoid cell receptors have been shown to play important roles in immune regulation particularly as potent modulators of anti-inflammatory cytokines. The predominant cannabinoid receptor involved in this immune regulation is cannabinoid receptor 2 (CB(2)), which is predominantly expressed in B lymphocytes. However, the promoter region and mechanisms of CB(2) gene regulation are unknown in this immune cell type. Utilizing a combination of bioinformatics, 5' rapid amplification of cDNA ends (5' RACE), real-time reverse transcription-polymerase chain reaction, DNA sequencing, and luciferase reporter assays, we show that human B cells express one CB(2) transcript while mouse B cells express three CB(2) transcripts, with specific transcript
