All of the following cells are found in lung EXCEPT (AIPG -2008)
1. Langerhans cell (D) the immature dendritic cells present in the skin and lymph nodes, reaching lungs only in abnormal conditions like Histiocytosis.
2. Kulchitsky cells (A) are the neuro-endocrine cells found in the lining epithelium of lung and belong to the APUD system.
3. Clara cells (B) are the non-ciliated cuboidal/columnar cells in the wall of terminal /respiratory bronchioles. They secrete the surfactant lipoproteins like the type-II pneumocytes.
4. Brush cells (C) have microvilli at their surface and are innervated by nerve fibres, and function as receptor cells.
