Association of serum CD14 level and functional polymorphism C-159T in the promoter region of CD14 gene with allergic rhinitis.

Allergic rhinitis (AR) is an inflammatory disease of the upper respiratory tract affecting a significant number of the world's population. It occurs as an IgE-mediated immune response of the nasal mucosa to inhaled allergens. The human Cluster of Differentiation 14 (CD14) is a glycosyl-phosphatidylinositol-anchored molecule expressed on the surface of monocytes and macrophages and functions as a receptor to lipopolysaccharides and inhaled endotoxins that may stimulate interleukins production by antigen-presenting cells.

A national overview of paediatric and adolescent and young adult surgical neuro-oncology in Pakistan.
