Spring Street, New York, NY 10013, U.S.A Preface It is widely accepted that “evidence-based dentistry” is fundamental to clinical practice and that well-controlled randomized clinical trials followed by systematic reviews and meta-­ analyses provide much of this evidence base However, it is still the basic biological and physical sciences that underpin advances in dentistry and form the basis for subsequent clinical trials It is equally true that the treatment of any disease should be based on an understanding of the etiology and pathogenesis of that disease, and in this context, the future of dentistry lies very much in continued research in the basic biological sciences This second edition of Oral Biology: Molecular Techniques and Applications continues the approach taken in the first edition and has not attempted to cover all aspects of oral biology, but rather to present a selection of cellular and molecular techniques that can be adapted to cover a range of applications and diseases The first part on saliva, for example, has been updated and expanded to include proteomic analyses by mass spectrometry and NMR-based metabolomics that can be used not only in the study of saliva but also in assessing other oral fluids such as gingival fluid Clearly, saliva is unique to the oral cavity but so too is gingival fluid which, in essence, is the fluid medium of the gingiva and gingival sulcus, and thus is the fluid environment where interactions between the plaque biofilm and the host take place Hence, techniques for its collection and analysis have now been included Although it is years since publication of the first edition of this book, many of the techniques described are still in widespread use and so have been retained, albeit updated, in this second edition In the part on molecular biosciences, for example, chapters on profiling of oral microbial communities, quantitative real-time PCR, and adhesion of yeast and bacteria to oral surfaces have all been retained but substantially updated Epigenetics is now a major theme in biology and is providing great insight into how we interact with our environment As DNA methylation features heavily in epigenetic studies, new chapters on tools and strategies that facilitate the analysis of genome-wide or gene-­ specific DNA methylation patterns have been included As in the first edition, the last part of this second edition deals with a range of approaches that enable the behavior of cells and tissues in both health and disease to be analyzed at the molecular level The future of dentistry and of the profession lies in research, and it is anticipated that this second edition of Oral Biology: Molecular Techniques and Applications will continue to be a useful resource for oral biologists at all levels, be they students, early career or experienced veterans, and that it provides a ready reference enabling new techniques and approaches to be used in answering a range of specific scientific questions that will underpin a deeper understanding and treatment of oral diseases Dunedin, New Zealand Dunedin, New Zealand Dunedin, New Zealand Gregory J. Seymour Mary P. Cullinan Nicholas C.K. Heng

Note 34) Notes Collect blood in lithium-heparin anti-coagulated tubes Experiments from our own laboratory reveal greater cell retrieval and less inadvertent cell activation compared with other anticoagulants Isolate cells as soon as possible We typically isolate approximately × 106 cells per mL of blood If possible, prepare gradients immediately prior to neutrophil isolation to minimize chance of gradient disruption; however, gradients may be carefully stored at °C for a day if needed It is more reliable to layer the 1.098 g/mL Percoll underneath the 1.079 g/mL Percoll solution Collect as few erythrocytes as possible to minimize the risk of erythrocyte contamination Erythrocyte lysis is indicated by the increased transparency of the blood/lysis buffer solution Do not incubate neutrophils in erythrocyte lysis buffer for longer than recommended due to the potential for cell activation If erythrocytes are taking time to lyse (solution to go clear) this could be due to the age of the lysis buffer, which should be stored for a maximum of weeks at °C During the lysis buffer/PBS washing stages and removal of supernatant, the operator must take care not to disturb the cell pellet to maximize cell retrieval We recommend duplicate cell counting using a haemocytometer and calculation of the mean We routinely ensure neutrophil viability by trypan blue exclusion and CellTiter-Glo® assays, as well as neutrophil purity by flow cytometry [23] Characterization, Quantification, and Visualization of Neutrophil Extracellular Traps 495 10 Adding % BSA to plasticware prior to the addition of neutrophils coats the surface, which has been found to reduce inadvertent neutrophil activation 11 A 30-min baseline period prior to neutrophil activation allows the cells to settle in the plastic-ware and neutrophils are more responsive to exogenous stimulation 12 HOCl and PMA stimuli are light-sensitive Make up/defrost at room temperature immediately prior to use and protect from light by foil wrapping 13 Following their release, NETs are attached to the neutrophil they are derived from The addition of MNase degrades the NET structures, which following centrifugation and the sedimentation of neutrophils, allows for the fluorometric quantification of NET-DNA in the supernatants 14 NETs are produced in response to HOCl in as little as 30 [9], PMA and bacteria typically induce NET production in and h, respectively 15 Following MNase digestion, neutrophils are centrifuged in a plate spinner If you not have a plate spinner then the well contents can be transferred to 1.5-mL centrifuge tubes for centrifugation 16 Care needs to be taken when transferring NET supernatants to a new plate to ensure the operator is not disturbing the neutrophils at the bottom of the well; tipping the plate toward you helps 17 Bacteria produce DNA [24] that can interfere with NET-DNA assays If quantifying NET production in response to bacteria, control wells containing bacteria in PBS (and no neutrophils) need to be measured and subtracted from the final NET production values We not employ a bacterial NET stimulus during Sytox green fluorescence microscopy as it is very difficult to distinguish between NET-DNA and bacterial DNA; therefore, use PMA or HOCl for NET fluorescence visualization 18 Sytox green does not permeate viable cells; therefore, very high readings (DNA) in control wells are indicative of high numbers of nonviable neutrophils 19 Neutrophils and the attached NET structures settle to the bottom of plastic-ware; however, they are not adherent cells and washing needs to be careful to minimize the disruption of NET structures 20 Washing removes components that are not NET-bound but are concurrently released during neutrophil activation 21 NET-bound components can be quantified immediately, or transferred to cryotubes and stored at °C (for up to week) or at −20 °C (for up to months) for quantification at a later date 496 Phillipa C White et al 22 The addition of DNase to NETs in selected wells produces degraded NET structures to serve as an additional control 23 The duplicate wash steps ensure bacteria not entrapped within NET structures are removed and therefore only the fluorescence of entrapped bacteria is measured 24 The addition of cytochalasin B to selected wells following NET release inhibits neutrophil phagocytosis and the addition of MNase degrades NETs 25 The addition of MNase postincubation disassembles the NETs and frees the bacteria prior to inoculation on agar plates 26 The dilution factor required prior to inoculating agar plates with bacteria needs to be determined in preliminary experiments for each bacterial species 27 Plasma is isolated from whole blood in mL lithium heparin anti-coagulant tubes by centrifuging for 30 at 1000 × g (4 °C) Following centrifugation, plasma is transferred to cryotubes in 500-μL aliquots and stored at −80 °C 28 The treatment of some wells with MNase will serve as a positive control and the MNase treatment is considered 100 % NET degradation 29 It is easier to handle coverslips for SEM use in 6-well plates 30 Wrapping agar plates in clingfilm helps to prevent the desiccation of agar following prolonged incubation 31 Periodontal bacteria typically take at least days to grow planktonically However, growth can be determined at any time point following inoculation of broth by assessing the turbidity, as determined by measuring the optical density at 600 nm 32 Confirm the bacterial species by gram staining and/or PCR 33 Planktonic bacteria are washed in PBS multiple times to remove broth prior to neutrophil assays 34 Killing of bacteria can be confirmed by inoculating a fresh agar plate with the heated bacteria suspension References Borregaard N, Cowland JB (1997) Granules of the human neutrophilic polymorphonuclear leukocyte Blood 89:3503–3521 Brinkmann V, Reichard U, Goosmann C, Fauler B, Uhlemann
