Abstract:
We have examined the developmental profile of the alpha-1 and alpha-2 adrenergic receptor mRNA expression in the rat iris. The expression of the six mRNAs was studied using reverse transcription-polymerase chain reaction. At 4 weeks, the dominant mRNA transcripts in the rat iris were alpha-1B, alpha-1C and alpha-2A. This pattern of alpha adrenoceptor expression was seen from birth, throughout development, and maintained into old age.

Adrenergic Receptors (Adrenoceptors): Classification
α-Adrenoceptors
α-Adrenoceptors are classified into two main subtypes: α1 and α2. The α1 adrenoceptors, which are found on postsynaptic...
Adrenergic Receptors: ɑ Subtype
Adrenaline ≥ Noradrenaline >> Isoprenaline
α-adrenoceptors are further divided into α1 and α2-adrenoceptors.
α1-Adrenoceptors: These receptors are located postsynaptically on the effector organs and cause constriction of smooth muscle mediated by activation of phospholipase C—inositol-1,4,5-trisphosphate...
Adrenergic Receptors: β Subtype
Isoprenaline > Adrenaline > Noradrenaline
Neurotransmitter binding to these receptors causes activation of adenylyl cyclase resulting in increased concentrations of cAMP and modulation of calcium ion channels within the cell. They are further classified into β1, β2, and β3 subtypes.
β1-adrenoceptors: β1-adrenoceptors have equal affinities for...
