Beta-receptor decrease in bronchial asthma

Sinesterases that intervene in cAMP and oGMP equilibrium in the cytoplasm of mast cells are activated by the adrenergic system through beta-receptors.

A study was made on 96 atopic patients with mono sensitization to Dermatophagoides pteronissinus, in 3 groups. Radioligands were used to quantitate the number of beta receptors. In the control group mean no/cell was 541, bronchial symptomatic patients had 327 and nasal symptomatics 348. Asymptomatic patients were similar to controls.

The results were similar with pollen-sensitive patients. Beta receptor decrease is a consequence of clinical allergy in atopic patients and is secondary to the immunological events that follow antigen-antibody reactions and cell membrane changes.
