    Notes: Summary The presence of the CRF-containing neurons in the hypothalamus was investigated in four different species (cats, dogs, pigs, and monkeys) by the peroxidase-antiperoxidase technique using specific anti-serum to CRF. In all animals examined, CRF-containing perikarya were found mainly in the paraventricular and supraoptic nuclei, and a small number of the immunoreactive cells were observed in the accessory supraoptic nucleus and the lateral hypothalamic area. The size of the CRF-containing perikarya ranged from 20–35 μm in diameter. These findings suggest that the magnocellular paraventricular and supraoptic nuclei are the center not only of the classical neurosecretory system for the production of the posterior lobe hormones, but also that of the CRF neuronal system.

    Notes: Abstract. A newly established human lymphoma cell line (OZ) has the t(14;18)(q32;q21) translocation and expresses large amounts of Bcl-2 compared to CCRF-CEM cells. VP-16 (40 μg/mL), a promising agent against lymphoma, caused DNA fragmentation (26.9% of total DNA) typical for apoptosis at 6 h in CCRF-CEM cells, but no significant changes in OZ cells until 24 h after the addition of VP-16. However, coincubation with calphostin C (0.2 μg/mL), a protein kinase C (PKC) inhibitor, induced DNA fragmentation in VP-16-treated OZ cells (13.5% of total DNA) at 6 h after the treatment. Simultaneous immunoblot analysis revealed that this induction of apoptosis coincided with the downregulation of serine-phosphorylated Bcl-2 (13% of control cells). By contrast, apoptosis induced by VP-16 in CCRF-CEM cells was attenuated by the addition of 0.5 μM phorbol 12-myristate 13-acetate, a potent PKC stimulator. These observations suggest that Bcl-2 function is partly regulated by phosphorylation/dephosphorylation mechanisms of the PKC system, and that phosphorylated Bcl-2 in lymphoma cells may play a role in the prevention of apoptosis.

    Notes: Summary By means of the peroxidase-antiperoxidase technique, in conjunction with a specific anti-CRF serum, it was shown that a large number of immunoreactive nerve fibers were demonstrable on the capillary loops of the hypophysial portal vessels in the external layer of the median eminence of the rat and monkey, particularly in its medial part. This result confirms the radioimmunological determination of CRF immunoreactivity in the median eminence.

    Elevation of Anti-cytokeratin 19 Antibody in Sera of the Patients With Idiopathic Pulmonary Fibrosis and Pulmonary Fibrosis Associated With Collagen Vascular Disorders (1999)

    Notes: Abstract. It has been suggested that cytokeratin 19 is expressed in regenerated bronchoepithelial cells in patients with pulmonary fibrosis, and serum cytokeratin 19 fragment is elevated in patients with pulmonary fibrosis. We hypothesized that serum antibodies to cytokeratin 19 may be formed in patients with pulmonary fibrosis. To prove the existence of anti-cytokeratin 19 antibodies in patients' sera, human recombinant cytokeratin 19 was stained with patients' sera by a Western immunoblot. Then, we tried to establish an enzyme-linked immunosorbent assay to quantitate anti-cytokeratin 19 antibody in the sera of patients with idiopathic pulmonary fibrosis (IPF) and pulmonary fibrosis associated with collagen vascular disorders (PF-CVD). We demonstrated the anti-cytokeratin 19 antibody in patient' sera by a Western immunoblot. In patients with IPF and PF-CVD, significantly high anti-cytokeratin 19 antibody was demonstrated compared with normal volunteers, patients with chronic bronchitis, and patients with pneumonia. These results suggest that anti-cytokeratin 19 antibody may have played a role in the process of lung injury in pulmonary fibrosis.

    Elevation of Anti-Cytokeratin 18 Antibody and Circulating Cytokeratin 18: Anti-Cytokeratin 18 Antibody Immune Complexes in Sera of Patients with Idiopathic Pulmonary Fibrosis (2000)

    Notes: Abstract. In this study, we hypothesize that anti-cytokeratin 18 (CK18) antibody and CK18:anti-CK18 immune complex increase in sera in patients with idiopathic pulmonary fibrosis (IPF). To prove the existence of anti-CK18 antibodies in patients' sera, bovine CK18 was stained with patients' sera using a Western blotting. In patients with IPF, anti-CK18 antibodies were clearly demonstrated in sera by Western blotting. Then, we tried to establish an enzyme-linked immunosorbent assay (ELISA) to quantify anti-CK18 antibodies and CK18:anti-CK18 immune complexes in sera of patients with IPF. Levels of anti-human CK18 antibodies in sera of patients with IPF (0.81 ± 0.31, mean ± SD) measured by ELISA were significantly high compared with that of normal volunteers (0.45 ± 0.06, p 〈 0.01). In addition, levels of CK18:anti-CK18 antibody complexes in patients' sera (0.64 ± 0.35, man ± SD) significantly increased compared with those of normal subjects (0.40 ± 0.10, p 〈 0.01). These results suggest that anti-CK18 antibody and its immune complex may have played a role in the process of lung injury in IPF.

    Notes: Summary The occurrence of CRF (corticotropin-releasing factor)-immunoreactive nerve fibers in the circumventricular organs of adult male monkeys, Macaca fuscata, was studied on serially sectioned brains, by means of the peroxidase-antiperoxidase technique in combination with a highly specific and sensitive CRF antiserum. CRF-containing nerve fibers were found in high concentrations in the infundibulum and, in addition, in small numbers in the posterior lobe, organum vasculosum laminae terminalis, subfornical organ, and area postrema; they were missing in the pineal body and the subcommissural organ. The CRF immunoreactive nerve fibers distributed in these organs were located in the proximity of the blood vessels.

    Notes: Summary Conspicuous differences in the distributional pattern of nerve fibers containing corticotropin-releasing factor (CRF) or posterior lobe hormones, respectively, were shown in the median eminence of the adult male rat by means of immunoperoxidase histochemistry, with the use of anti-CRF, anti-oxytocin, and anti-vasopressin sera. In the rostral and central divisions of the median eminence, a high concentration of CRF-immunoreactive nerve fibers was found in the median portion of the external layer; these fibers terminated on the capillary loops of the hypophysial portal system. In the caudal division of the median eminence, the CRF-immunoreactive nerve fibers were located in the median to paramedian portions of the external layer. Numerous oxytocin- and vasopressin-immunoreactive nerve fibers were observed evenly distributed throughout the internal layer of the median eminence. In the external layer, a small number of the oxytocin- and vasopressin-containing nerve fibers was found around the capillary loops, particularly in the median to paramedian portions. The distributional patterns of the CRF and the posterior lobe hormones in the hypothalamo-hypophysial system and their functional interrelationship are discussed.

    Notes: Summary A specific rabbit anti-CRF serum and the immunoperoxidase technique were used to show that CRF-containing neurons are mainly distributed in the paraventricular and supraoptic nuclei of the rat hypothalamus. In addition, immunoreactive neurons are scattered in other hypothalamic regions. These neurons are 20–30 μm in diameter. From the present and previous investigations it may be concluded that the hypothalamic magnocellular nuclei, i.e., paraventricular and supraoptic, and other hypothalamic accessory nuclei, are the producing sites not only for vasopressin and oxytocin, but also for corticotropin-releasing factor.
