Oncogene-induced senescence (OIS) is crucial for tumour suppression. Senescent cells implement a complex pro-inflammatory response termed the senescence-associated secretory phenotype (SASP). The SASP reinforces senescence, activates immune surveillance and paradoxically also has pro-tumorigenic properties. Here, we present evidence that the SASP can also induce paracrine senescence in normal cells both in culture and in human and mouse models of OIS in vivo. Coupling quantitative proteomics with small-molecule screens, we identified multiple SASP components mediating paracrine senescence, including TGF- family ligands, VEGF, CCL2 and CCL20. Amongst them, TGF- ligands play a major role by regulating p15(INK4b) and p21(CIP1). Expression of the SASP is controlled by inflammasome-mediated IL-1 signalling. The inflammasome and IL-1 signalling are activated in senescent cells and IL-1 expression can reproduce SASP activation, resulting in senescence. Our results demonstrate that the SASP can cause paracrine senescence and impact on tumour suppression and senescence in vivo.

Epstein-Barr virus (EBV) is associated with multiple sclerosis (MS), and antibodies to the EBV nuclear antigen-1 (EBNA-1) are consistently increased in MS patients. The hypothesis of this study is that anti-EBNA-1 antibodies cross-react with a self antigen in MS patients. We affinity purified anti-EBNA-1 antibodies from human plasma, used the anti-EBNA-1 to immunoprecipitate antigens from human brain, and identified bound antigens with mass spectrometry. Anti-EBNA-1 consistently bound heterogeneous nuclear ribonucleoprotein L (HNRNPL). We expressed both the long and short isoforms of this protein, and verified with Western blots and ELISA that the long isoform cross-reacts with EBNA-1. Immunohistochemistry demonstrated that anti-EBNA-1 bound to an antigen in the nucleus of cultured rat central nervous system cells. ELISA demonstrated the presence of antibodies to HNRNPL in the plasma of both healthy controls and MS patients, but anti-HNRNPL was not increased in MS patients. We conclude that HNRNPL is an autoantigen which cross-reacts with EBNA-1. The relevance of this autoantigen to MS and other autoimmune diseases remains to be investigated.

Objective: To assess the association of dietary flavonol intake with the subsequent risk of coronary heart disease (CHD) mortality. Design: Meta-analysis of prospective cohort studies published before September 2001. Studies were identified by MEDLINE and EMBASE searches and by scanning relevant reference lists. The following information was extracted from published reports: size of cohort, mean age, mean duration of follow-up, number of fatal CHD events, mean flavonol intake, main sources of flavonol intake, degree of adjustment for potential confounders, and the relation of CHD mortality to dietary flavonol intake measured at baseline. Results: Seven prospective cohorts of men and women were identified including a total of 2087 fatal CHD events. Comparison of individuals in the top third with those in the bottom third of dietary flavonol intake yielded a combined risk ratio of 0.80 (95% CI 0.690.93) after adjustment for known CHD risk factors and other dietary components. Conclusion: This overview of prospective cohort studies indicates that high dietary intake of flavonols from a small number of fruits and vegetables, tea and red wine may be associated with a reduced risk from CHD mortality in free-living populations.
