    Notes: During starvation, counterregulatory responses to loss of food (i.e. responses that lead to an increase in appetite) occur in the central nervous system (CNS). This study was designed to examine whether middle-aged rats show greater or smaller behavioural, peripheral and central hormonal responses during starvation compared to young rats. In experiment 1, refeeding following 4 days of starvation was measured in both middle-aged (72-week-old) and young (9-week-old) rats. The level of refeeding was similar to each prestarved level until 3 days after the end of starvation in both groups. From the 4th day, the level of refeeding in young rats increased and reached beyond the prestarved level, whereas refeeding in middle-aged rats remained similar to the prestarved level. Thus, overall refeeding throughout 7 days was greater in young rats than in middle-aged rats. In experiment 2, middle-aged and young rats were starved for 4 days and were killed in the morning. Middle-aged rats showed a smaller plasma corticosterone response than that of young rats. The magnitude of decreases in plasma glucose, insulin and leptin was similar in both groups. In the arcuate nucleus, the starvation-induced increase in neuropeptide Y (NPY) mRNA and the decrease in proopiomelanocortin (POMC) mRNA were smaller in middle-aged rats than in young rats. In contrast, the starvation-induced decrease in corticotrophin-releasing hormone (CRH) mRNA in the hypothalamic paraventricular nucleus was greater in middle-aged rats than young rats. The magnitude of decrease in type-2 CRH receptor mRNA in the ventromedial hypothalamus was similar in both groups. The results indicate that (a) ageing impaired refeeding response (b), middle-aged rats showed the same directional neuropeptide mRNA responses as seen in young rats during starvation and (c) the magnitude of these counterregulatory responses in the CNS in middle-aged versus young rats was not uniform, but rather was site-specific or neuropeptide-specific. This study suggests the importance of NPY and POMC responsiveness in the arcuate nucleus in the age-related differences resulting from starvation-induced refeeding.

    Notes: In our previous study, apparent reduction of glucocorticoid receptor (GR) mRNA was seen in the hippocampus and the hypothalamic paraventricular nucleus (PVN) during repeated immobilization (IMO) stress, but not following starvation. Our laboratory has also shown that the sp1 activates, whereas tumour suppressor p53 represses the promoter activity of GR gene. In an attempt to reveal the possibility that transcription factors such as sp1 and/or p53 are involved in the regulation of GR mRNA expression in the hippocampus and in the PVN in vivo, we examined the expression of GR mRNA, p53 mRNA, and sp1 mRNA in the hippocampus and in the PVN during repeated IMO and following starvation. In addition, the expression of these mRNAs was examined in the anterior pituitary, another GR-rich area. GR mRNA in all subfields of the hippocampus was robustly decreased, while GR mRNA in the anterior pituitary was increased, 24 h following 4 × IMO (2 h daily, for 4 consecutive days) and immediately after 5 × IMO. GR mRNA in the PVN was significantly decreased immediately after 5 × IMO, but not at 24 h after 4 × IMO. Conversely, p53 mRNA in the PVN and hippocampus was increased, whereas p53 mRNA in the anterior pituitary was decreased, 24 h following 4 × IMO and immediately after 5 × IMO. Sp1 mRNA was unchanged in all areas examined following repeated IMO. Following 4 days of starvation, neither GR mRNA, p53 mRNA nor sp1 mRNA showed any changes in the PVN and the hippocampus, except there was a minor decrease in GR mRNA in CA1-2. In the anterior pituitary, 4 days of starvation induced a minor, but significant increase in GR mRNA, whereas it decreased p53 mRNA. Overall, regression analyses revealed a negative correlation between GR mRNA levels and p53 mRNA levels in CA1-2 and dentate gyrus of the hippocampus and in the anterior pituitary. GR mRNA in the PVN also showed a tendency towards the negative correlation with p53 mRNA levels. The results raise the possibility that p53 negatively regulates GR mRNA expression in the PVN, the hippocampus and the anterior pituitary during repeated immobilization stress.

    Notes: Background There are no reports of respiratory epithelial damage induced by immuiioglobulin-stimulated eosinophils.Objective We tried to induce damage to respiratory epithelium by guinea-pig (GP) eosinophils stimulated with guinea-pig IgG (GP-lgG)-coated Sepharose 4B beads. Methods GP tracheal epithelium was cultured together with GP eosinophils that had been collected from the peritoneal cavity, purified on a Percoll gradient, and stimulated with GP-lgG-coated beads (GP eosinophils:beads = 20:1). Damage to the epithelium was observed with an inverted microscope.Results After 24 h of culture with three 106 eosinophils. irregularity of the surface of the epithelium, desquamation. shedding of cilia, and abnormal beating of cilia were observed. This damage was first observed after 12 h of incubation, and was more severe at 24 h. No damage was found when beads coated with human serum albumin (HSA) were used. GP eosinophils stimulated with GP-IgG released significantly more EPO than those stimulated with HSA. at 6 and 24 h. Heparin and eatalase partially inhibited the epithelial damage. O2-production by eosinophils was also enhanced with GP-IgG-coated beads. Conclusion Both granule basic proteins and reactive oxygen radicals may be responsible for epithelial damage, probably via an EPO + H2O2+ halide system. These results confirmed that stimulated eosinophils can damage respiratory epithelium.

    Notes: Background We have shown that interleukin-5 (IL-5) and granulocyte-macrophage colony-stimulating factor (GM-CSF) are present in sputum from patients experiencing acute asthma attacks, by eosinophil survival assay. The viability of guinea-pig eosinophils was significantly increased in the presence of such sputum extracts after 3 days' culture, and it was inhibited by the addition of anti-IL-5 and anti-GM-CSF antibodies. However, the contribution of IL-5 to the increase in eosinophil viabihty was less than expected from the values of IL-5 measured by enzyme-linked immunosorbent assay (ELISA). Therefore, we speculated that something in sputum inhibited the function of IL-5.Objective Tratnsforming growth factor-β (TGF-β) was the only cytokine we tested that inhibited the prolongation of survival of guinea-pig eosinophils induced by IL-5. The objective of this study is to detect TGF-β in the same sputum. Methods Guinea-pig eosinophils were cultured with or without anti-TGF-β antibody in the presence of sputum extracts, and the eosinophil viability was counted after 3 days. Measurement of TGF-βl in sputum was performed by ELISA. Results Eosinophil viabilities with and without anti-TGF-β antibody were 79.7 ± 2.9% and 69.0 ± 2.7%, respectively, and the difference between them was statistically significant (P 〈 0.05, n = 9). The concentration of TGF-β1 in the sputum was 21.7 ± 3.3 ng/mL (n = 9).Conclusion These observations suggest that TGF-β is present in sputum from patients with bronchial asthma.

    The N-terminal prepeptide is required for the production of spore cortex-lytic enzyme from its inactive precursor during germination of Clostridium perfringens S40 spores (2000)

    Notes: A spore cortex-lytic enzyme of Clostridium perfringens S40 is synthesized during sporulation as a precursor consisting of four domains. After cleavage of an N-terminal preregion and a C-terminal proregion, inactive proenzyme (termed C35) is converted to active enzyme by processing of an N-terminal prosequence with germination-specific protease (GSP) during germination. The present results demonstrated that the cleaved N-terminal prepeptide remained associated with C35. After the isolated complex was denatured and dissociated in 6 M urea solution, removal of urea regenerated a prepeptide–C35 complex which produces active enzyme when incubated with GSP. However, isolated C35 alone could not be activated by GSP. The prepeptide–C35 complex was more heat stable than active enzyme. Thus, non-covalent attachment of the prepeptide to C35 is required to assist correct folding of C35 and to stabilize its conformation, suggesting that the prepeptide functions as an intramolecular chaperone. Recombinant proteins, which have prepeptide covalently bonded to C35, were processed by GSP as well as the in vivo prepeptide–C35 complex, and the full length of the N-terminal presequence was needed to fulfil its role. Although the C-terminal prosequence is present as an independent domain which is not involved in the activation process of the enzyme, it appears that the N-terminal prosequence contributes to the regulation of enzyme activity as an inhibitor of the enzyme.
