1 Long-term pretreatment with PMA greatly reduced the contribution of agonist-induced desensitization to the angiotensin II response; in contrast, the extent of desensitization occurring during incubation of WB cells with epinephrine was unaltered by long-term treatment with PMA suggesting that an additional mechanism may be involved in alpha 1-adrenergic receptor desensitization.
