Abstract:
OBJECTIVE:To observe expression and distribution of histamine H4 receptor in nasal mucosa in normal people and allergic rhinitis patients,and understand role of histamine H4 receptor in allergic rhinitis.
METHOD:Select normal people and allergic rhinitis patients each 10, take the nasal mucosa, detect expression and distribution of histamine H4 receptor at proteins and transcription level respectively by immunohistochemical method and RT-PCR, and compared.
RESULT:Histamine H4 receptor at proteins and transcription level were found in normal nasal mucosa (25 509 +/- 6 441, 0.42 +/- 0.08), increased significantly in nasal mucosa of allergic rhinitis patients (49 676 +/- 8 541, 0.69 +/- 0.11, P < 0.05), which in structural cells and immune cells.
CONCLUSION:Histamine H4 receptors exist in normal nasal mucosa, its express significantly enhance, flew histamine H4 receptor may be mediated histamine in pathogenesis of allergic rhinitis ,who is one of the ligands of histamine.
