despite this fact , cholera toxin was able to produce a marked increase in camp content , adenylate cyclase activity and protein kinase activation in h35 cells . binding studies with [ 125 i ] -iodohydroxybenzylpindolol , a specific beta-adrenergic receptor antagonist , revealed that each h35 cell possesses fewer than 10 beta-adrenergic receptors whereas brl cells contain 2-5,000 receptors per cell .
