Figure 5From: Neurotrophins and neurotrophin receptors in pulmonary sarcoidosis - granulomas as a source of expression Neurotrophin and neurotrophin receptor immunostaining in sarcoid lung tissue. Immunostainings for NGF (A, G), NT-3 (B, H), BDNF (C, I), TrkA (D, J), TrkC (E, K) and TrkB (F, L) on lung biopsy sections from sarcoidosis patients (×20). Ep: epithelium, Sm: smooth muscle, Ic: infiltrating inflammatory cells and AM: alveolar macrophages. Non-specific (NS) immunostainings are shown in (M & N) and were obtained by exposing the sections to the antibodies preabsorbed with the corresponding blocking peptide.Back to article page
