Figure 4From: Neurotrophins and neurotrophin receptors in pulmonary sarcoidosis - granulomas as a source of expression Neurotrophin and neurotrophin receptor immunostaining in sarcoid lymph node granulomas. Immunostainings for NGF (A), NT-3 (B), BDNF (C), TrkA (D), TrkC (E) and TrkB (F) on sections of a mediastinal lymph node from a patient with sarcoidosis (×20). Positive immunostaining was localized to the granulomas. Non-specific (NS) immunostaining is shown in G) and was obtained by exposing the sections to the antibodies preabsorbed with the corresponding blocking peptide.Back to article page
