1.Proteome identification of common immunological proteins of two nematode parasites
Parasites, Hosts and Diseases 2024;62(3):342-350
Although helminth parasites have different life cycles, their hosts share similar immune responses involving Th2 cell-type. Here, we extracted proteins from the larvae of Anisakis simplex complex and Trichinella spiralis to identify common and specific antigens (or allergens) associated with the Th2 immune response. We performed two-dimensional electrophoresis analysis and Matrix-assisted laser desorption ionization–time of flight/time of flight (MALDI-TOF/TOF) experiments. We found 13 potentially immunogenic proteins, which included 5 spots specific to T. spiralis and 8 common to T. spiralis and A. simplex, by tandem mass spectrometry. These molecules were identified structurally as actin, tropomyosin, col cuticle N domain-containing protein, and heat shock proteins. We also identified molecules related to parasite-host immune modulation and interactions. Our results may contribute to reveal potential roles of immunological proteins in parasite-derived immune modulation.

An abnormal dipping pattern in ambulatory blood pressure monitoring (ABPM) is a cardiovascular (CV) risk factor. However, its impact on CV mortality has not been investigated sufficiently in clinical practice to be considered a standard parameter. We assessed the association between abnormal dipping patterns and increased CV mortality in a tertiary hospital in Korea. Our retrospective cohort study included 401 patients who underwent ABPM between 1994 and 1996 in Hanyang University Hospital, Seoul, Korea. The patients were classified as risers (<0% drop in systolic BP; n=107), and others included dippers and non-dippers (> or =0% drop, n=294). The follow-up period was 120 months. The frequency of CV mortality was 14.0% in risers and 5.8% in others. A Cox regression analysis found a significant association between dipping pattern and CV mortality, after adjusting for age, gender, body mass index, hypertension, diabetes mellitus, smoking and hypercholesterolemia. Risers were at greater risk of CV death than others (RR, 3.02, P=0.022), but there was no difference in event rates between dippers and non-dippers. The reverse dipping pattern may be more frequent in clinical settings than in the population at large, and it is strongly associated with increased risk of CV mortality in Korea.

IgA nephropathy is the most common form of primary glomerulonephritis and chronic glomerular disease worldwide including Korea. Familial gathering of IgA nephropathy suggests that genetic factors contribute to the development of this disease. Although there have been many reports on familial IgA nephropathy with genetic analysis and their pedigrees, there has been few reports in Korea. We reported a partial familial IgA nephropathy pedigree with a brief review of the literatures.

BACKGROUND: Several studies have shown that family meals promote a well-balanced and healthier diet and weight status. Metabolic syndrome is related to eating behavior. This study investigated the association between eating family meals and the prevalence of metabolic syndrome. METHODS: This cross-sectional study included 4,529 subjects who participated in the Korea National Health and Nutrition Examination Survey IV and V (2007–2012). A self-reported questionnaire was used to assess dietary status. Metabolic syndrome was defined according to the guidelines of the modified version of the National Cholesterol Education Program Adult Treatment Panel III. We compared the overall quality of dietary intake in family meal. RESULTS: Nutritional adequacy ratios for energy, protein, calcium, vitamin A, vitamin B₁, vitamin B₂, vitamin C, niacin, and potassium, and the mean adequacy ratio were significantly higher in the family meal group (P<0.05). The prevalence of metabolic syndrome was lower in the family meal group (P<0.05). However, we observed no significant association between eating family meals and the prevalence of metabolic syndrome. CONCLUSION: This study demonstrated that eating family meals appeared to be associated with nutrient adequacy. However, we observed no significant differences in prevalence of metabolic syndrome between the 2 groups.

OBJECTIVE: Ectopic pregnancy can still cause maternal death, though we have undergone it frequently. So, we survey 80 cases ectopic pregnancies treated our hospital for early detection and proper management. METHODS: In this study, the authors studied retrospectively 80 cases which had been admitted and treated at the department of Obstetrics and Gynecology, National Police Hospital from Jan. 1, 1991 to Dec. 31, 2000. RESULTS: Incidence of ectopic pregnancy was one in 68 normal deliveries for 10 years, 63.7% of cases occurred in 25~34 years-old age group, and 52.6% of patients had previous abdominal surgery including cesarean section. Average interval of tubal ligation was 6.5 years between the onset of ectopic pregnancy and tubal ligation. Lower abdominal pain was the most common clinical symptom developed in 91.3% of the patients. Average interval between the onset of symptom and LMP was 7.6 weeks. Most ectopic pregnancies were tubal pregnancies and salpingectomy was done in 56.3% of the patients. CONCLUSION: According to our study, ectopic pregnancy occurred most frequently in women in their reproductive age and one of most important prognostic factors is time between onset of symptom and arrival of patient at hospital. We must make our efforts to preserve utero-ovarian function in treatment of patients with ectopic pregnancy.

As most infections by the helminth parasite elicit the recruitment of CD4+CD25+Foxp3+ T (T(reg)) cells, many scientists have suggested that these cells could be used for the treatment of immune-mediated inflammation and associated diseases. In order to investigate the distribution and alteration of activated T(reg) cells, we compared the expression levels of T(reg) cell activation markers in the ileum and gastrocnemius tissues 1, 2, and 4 weeks after infection. The number of T(reg) cells was monitored using GFP-coded Foxp3 transgenic mice. In mice at 1 week after Trichinella spiralis infection, the number of activated T(reg) cells was higher than in the control group. In mice at 2 weeks after infection, there was a significant increase in the number of cells expressing Foxp3 and CTLA-4 when compared to the control group and mice at 1 week after infection. At 4 weeks after infection, T. spiralis was easily identifiable in nurse cells in mouse muscles. In the intestine, the expression of Gzmb and Klrg1 decreased over time and that of Capg remained unchanged for the first and second week, then decreased in the 4th week. However, in the muscles, the expression of most chemokine genes was increased due to T. spiralis infection, in particular the expression levels of Gzmb, OX40, and CTLA-4 increased until week 4. In addition, increased gene expression of all chemokine receptors in muscle, CXCR3, CCR4, CCR5, CCR9, and CCR10, was observed up until the 4th week. In conclusion, various chemokine receptors showed increased expressions combined with recruitment of T(reg) cells in the muscle tissue.

OBJECTIVE: The objectives of this study was to evaluate the correlation between myeloid differentiation protein 88 (MyD88) expression and paclitaxel effects on epithelial ovarian cancer cells and to evaluate whether paclitaxel had anti-apoptotic signals. METHODS: Epithelial ovarian cancer cells isolated from ascites and established cell lines were treated with increasing concentrations of paclitaxel (0.2 to 20 microM) for 24 and 48 hours and cell viability was determined using the CellTiter 96 AQueous One Solution Cell Proliferation Assay. Cytokine profiling was performed from culture supernatants using the Luminex 200 system. Nuclear factor-kappaB (NF-kappaB) activity was determined using a Luciferase reporter system. Levels of phospho-extracellular signal-regulated kinase (p-ERK) were measured by Western blot analysis. RESULTS: A strong signal for MyD88 expression was observed in R182, 01-19b and SKOV3 cells (MyD88-positive). A2780, R454 and 01-28 cells showed low levels of MyD88 (MyD88-negative). Paclitaxel effectively decreased cell viability in MyD88-negative A2780, R454, 01-28 cells after 24 and 48 hours (57%, 49%, 42% and 35%, 28%, 29%, respectively). MyD88-positive cells were resistant to paclitaxel. There was a significant increase in caspase-3/7 activity following paclitaxel treatment in MyD88-negative cells. No significant change in caspase-3/7 activity was detected in MyD88-positive cells. Paclitaxel induced NF-kappaB activation and enhanced the secretion of interleukin-6 (IL-6) and IL-8 in a dose dependent manner and induced ERK phosphorylation on MyD88-positive cells. CONCLUSION: Paclitaxel treatment for MyD88-positive ovarian cancer could have detrimental effects due to the paclitaxel-induced enhancement of NF-kappaB, ERK activities and pro-inflammatory cytokine production, which promote chemoresistance and tumor progression.
