Neutrophil extracellular traps (NETs) represent extracellular structures able to bind and kill microorganisms. It is believed that they are generated by neutrophils undergoing cell death, allowing these dying or dead cells to kill microbes. We show that, following priming with granulocyte/macrophage colony-stimulating factor (GM-CSF) and subsequent short-term toll-like receptor 4 (TLR4) or complement factor 5a (C5a) receptor stimulation, viable neutrophils are able to generate NETs. Strikingly, NETs formed by living cells contain mitochondrial, but no nuclear, DNA. Pharmacological or genetic approaches to block reactive oxygen species (ROS) production suggested that NET formation is ROS dependent. Moreover, neutrophil populations stimulated with GM-CSF and C5a showed increased survival compared with resting neutrophils, which did not generate NETs. In conclusion, mitochondrial DNA release by neutrophils and NET formation do not require neutrophil death and do also not limit the lifespan of these cells.

Ex Output:
Viable neutrophils release mitochondrial DNA to form neutrophil extracellular traps

BACKGROUND Several studies have demonstrated that women with nonobstructive coronary disease have a high rate of subsequent investigations, rehospitalizations for recurrent chest pain, and repeat coronary angiography. The sex specificity of this finding is unclear. We therefore undertook an evaluation of sex differences in rehospitalization for acute coronary syndrome (ACS) or chest pain in patients with "angiographically normal" coronaries.
METHODS A retrospective cohort study using prospectively collected angiographic and clinical data on all patients in British Columbia, Canada, presenting for their first cardiac catheterization with suspected ischemic heart disease but angiographically normal coronaries.
RESULTS Among 32,856 patients, 7.1% of men versus 23.3% of women were angiographically normal (P < .001). Among angiographically normal patients, women were older and more likely to present with hypertension, prior stroke, chronic obstructive pulmonary disease, and peripheral vascular disease than men, but Canadian Cardiovascular Society class of angina did not vary by sex. Within 1 year, 1.0% died, (19 women, 18 men, P = .27) and 0.6% had a stroke (13 women, 9 men, P = .91). Readmission to hospital for ACS or chest pain requiring catheterization was significantly higher in women compared to men (adjusted OR 4.06; 95% CI 1.15-14.31).
CONCLUSIONS In a contemporary, population-based cohort presenting for cardiac catheterization for suspected ischemia, women with angiographically normal coronaries were >4 times more likely to be readmitted to hospital for ACS/chest pain within 180 days compared to men. The observed sex difference has important social and economic implications and suggests that traditional diagnostic methods may not be optimal for women.

Interfering with the activity of polo-like kinases can lead to the formation of monopolar spindles. Polo-like kinases also regulate mitotic entry, activation of the anaphase-promoting complex and the necessary preconditions for cytokinesis. Similarities between the phenotypes of the Drosophila mutants asp and polo point towards a common role in spindle pole function. The abnormal spindles of asp mutants are bipolar but have disorganized broad poles at which -tubulin has an abnormal distribution. Moreover, the synergism or of polo1 aspE3 double mutants indicates a possible involvement of these genes in a common process. Asp is a microtubule-associated protein of relative molecular mass 220,000 (Mr 220K) found at the face of the centrosome that contacts spindle microtubules. In partially purified centrosomes, it is required with -tubulin to organize microtubule asters. Here, we show that Asp is the previously identified Mr 220K substrate of Polo kinase. Polo phosphorylates Asp in vitro, converting it into an MPM2 epitope. Polo and Asp proteins immunoprecipitate together and exist as part of a 2538S complex. Extracts of polo-derived embryos are unable to restore the ability of salt-stripped centrosomes to nucleate microtubule asters. This can be rescued by addition of phosphorylated Asp or active Polo kinase.

Ex Output:
Polo kinase and Asp are needed to promote the mitotic organizing activity of centrosomes
