[HTML][HTML] Induction of phosphodiesterases 3B, 4A4, 4D1, 4D2, and 4D3 in Jurkat T-cells and in human peripheral blood T-lymphocytes by 8-bromo-cAMP and Gs …

In this study, a potential mechanism of β 2-adrenoreceptor desensitization has been
explored that is based upon the enhanced degradation of cAMP by phosphodiesterase
(PDE). Pretreatment of Jurkat T-cells with 8-bromo cAMP (8-Br-cAMP) or prostaglandin E 2
increased PDE3 and PDE4 activity in an actinomycin D-and cycloheximide-sensitive
manner. This effect was associated with increased expression of HSPDE3B, HSPDE4A4,
HSPDE4D1, HSPDE4D2, and HSPDE4D3 mRNA transcripts. Western analysis reproducibly …
