The research aims to examine the expression of CysLT1 and CysLT2 receptors in asthmatic lungs and their influence on bronchial contractions.
Analyzed airway tissue from asthma and non-asthma subjects using immunohistochemistry.
Evaluated the effects of CysLT2 receptor antagonists on antigen-induced bronchial contraction in vitro.
Compared receptor expression levels between asthma and non-asthma subjects.
CysLT1 and CysLT2 receptors are expressed in bronchi smooth muscle, epithelium, and alveolar leukocytes.
Higher relative expression of CysLT2 receptors is observed in asthmatic lungs compared to non-asthmatic lungs.
CysLT2 antagonism showed varying effects on bronchial contractions in asthma, indicating complexities in receptor interactions.
