Expression of HSP47 in Usual Interstitial Pneumonia and Nonspecific Interstitial Pneumonia
BACKGROUND: Heat shock protein (HSP) 47, a collagen-specific molecular chaperone, is involved in the processing and/or secretion of procollagens, and its expression is increased in various fibrotic diseases. The aim of this study was to determine whether quantitative immunohistochemical evaluation of the expression levels of HSP47, type I procollagen and α-smooth muscle actin (SMA) allows the differentiation of idiopathic usual interstitial pneumonia (UIP) from UIP associated with collagen vascular disease (CVD) and idiopathic nonspecific interstitial pneumonia (NSIP). METHODS: We reviewed surgical lung biopsy specimens of 19 patients with idiopathic UIP, 7 with CVD-associated UIP and 16 with idiopathic NSIP and assigned a score for the expression of HSP47, type I procollagen and α-SMA in type II pneumocytes and/or lung fibroblasts (score 0 = no; 1 = weak; 2 = moderate; 3 = strong staining). RESULTS: The expression level of HSP47 in type II pneumocytes of idiopathic UIP was significantly higher than in CVD-associated UIP and idiopathic NSIP. The expression of HSP47 in fibroblasts was significantly higher in idiopathic UIP and idiopathic NSIP than in CVD-associated UIP. The expression of type I procollagen in type II pneumocytes was significantly higher in idiopathic UIP than in idiopathic NSIP. The expression of type I procollagen in fibroblasts was not different in the three groups, while the expression of α-SMA in fibroblasts was significantly higher in idiopathic UIP than in idiopathic NSIP. CONCLUSION: Our results suggest the existence of different fibrotic pathways among these groups involved in the expression of HSP47 and type I procollagen
Generation and Characterization of Conditional Heparin-Binding EGF-Like Growth Factor Knockout Mice
Recently, neurotrophic factors and cytokines have been shown to be associated in psychiatric disorders, such as schizophrenia, bipolar disorder, and depression. Heparin-binding epidermal growth factor-like growth factor (HB-EGF) is a member of the EGF family, serves as a neurotrophic molecular and plays a significant role in the brain. We generated mice in which HB-EGF activity is disrupted specifically in the ventral forebrain. These knockout mice showed (a) behavioral abnormalities similar to those described in psychiatric disorders, which were ameliorated by typical or atypical antipsychotics, (b) altered dopamine and serotonin levels in the brain, (c) decreases in spine density in neurons of the prefrontal cortex, (d) reductions in the protein levels of the NR1 subunit of the N-methyl-D-aspartate (NMDA) receptor and post-synaptic protein-95 (PSD-95), (e) decreases in the EGF receptor, and in the calcium/calmodulin-dependent protein kinase II (CaMK II) signal cascade. These results suggest the alterations affecting HB-EGF signaling could comprise a contributing factor in psychiatric disorder

Epstein-Barr virus infected cells in the aqueous humour originated from nasal NK/T cell lymphoma
Nasal natural killer (NK)/T cell lymphoma is a definitive diagnostic entity in the World Health Organization lymphoma classification.1 In many cases, NK/T cell lymphoma is invariably associated with Epstein-Barr virus (EBV). Although ocular involvement is found in less than 10% of patients with systemic lymphoma,2 because of its anatomical proximity, nasal NK/T lymphoma can sometimes complicate uveitis and orbital infiltration.3 We experienced a case of nasal NK/T lymphoma, and the cells collected from the aqueous humour originated from the lymphoma which was infected by EBV.www.bmj.co
