No part of this publication may be reproduced, distributed or transmitted without the prior written permission of ECI. Some information may be subject to change. Information on Poster Presentations Posters are numerically the major scientific presentations of the meeting. The majority of congress attendees present a poster showing data and progress with their personal research. Posters offer an excellent opportunity for people interested in a particular topic to meet and exchange ideas and network with other researchers. Posters should NOT be used to advertise a product or service. Like a paper, a poster abstract should detail the focus of the presentation and the way(s) in which it contributes to the body of knowledge in its field. Guided Poster Sessions (Monday, Tuesday and Wednesday from 09:45 to 11:15) will be chaired by ECI faculty members and senior researchers within the respective areas and should be used for communication and interaction with the poster presenters, who are requested to be at their posters at these times. Scientific posters are displayed in the poster area in the Exhibition Hall. Each poster will be displayed for one full day either on Monday, Tuesday or Wednesday. Each day, the posters are organized in thematic groups of approx. 20 posters: POSTER SESSIONS The scientific program is divided into 4 main topic tracks: Track A: Adaptive Immunity Track B: Diseases Track C: Innate Immunity Track D: Disease Intervention Track E: Other Additionally a fifth track (Track E) combining topics which do not fit within the four main tracks was introduced. The 4-track program will streamline keynote lectures, symposia, workshops as well as guided poster walks in a way that will promote easy cross talk between the basic topics and types of sessions planned. Poster presentations will follow this track logic and the according sessions are scheduled as follows: Monday (09:45 – 11:15) Tuesday (09:45 – 11:15) Wednesday (09:45 – 11:15) Track A Adaptive Immunity Track B Diseases Track C Innate Immunity Track D Disease Intervention Track E Other P.A.01 - 10 P.B.01 - 14 P.C.01 - 08 P.D.01 - 10 P.E.01 P.A.11 - 19 P.B.15 - 28 P.C.09 - 16 P.D.11 - 18 P.E.02 - 03 P.A.20 - 28 P.B.29 - 42 P.C.17 - 24 P.D.19 - 27 P.E.04 - 05 During the guided poster sessions (09:45 – 11:15 on Monday, Tuesday and Wednesday) the presenters are required to stand by their posters to deliver a concise poster presentation of not more than 3 minutes and to answer questions from delegates. During this time, one or two chairpersons per thematic group will visit each poster and ask the presenters to briefly present their findings. SCHEDULE FOR POSTER MOUNTING AND POSTER REMOVAL / FLOOR PLAN Poster Mounting Poster Session Poster Removal Monday 07:30 - 08:30 09:45 – 11:15 18:00-19:30 Tuesday 07:30 - 08:30 09:45 – 11:15 18:00-19:30 Wednesday 07:30 - 08:30 09:45 – 11:15 16:00-17:45 All poster boards are marked with three color-coded poster numbers, one number for each day. You can find your individual poster board number in the author index at the end of this publication. The second letter in your poster number indicates the thematic track your poster is being presented in, e.g. P.A.01.01 is being presented in Track A – Adaptive Immunity. The areas of the respective tracks within the poster exhibition are indicated in the floor plan on the next page. This should make it easy for you to locate your poster wall. Please visit the Poster Information Desk located at the entrance of the exhibition area for any questions you might have regarding the poster presentations. Poster Presentations at the 4th European Congress of Immunology - ECI 2015 - Vienna, Austria 1 Information on Poster Presentations Please note that the organizers cannot assume any liability for loss or damage of posters displayed in the poster area. Posters need to be removed on the day of presentation between 18:00 – 19:30 hrs strict (16:00 – 17:45 hrs on Wednesday). Access after 19:30 hrs (17:45 hrs on Wednesday) is not possible! Posters not removed until 19:30 hrs on the day of presentation (17:45 hrs on Wednesday), will be taken down by the staff of the conference center and will not be stored or sent to the authors after the meeting. FORMAT The usable surface on the poster board will be 90 cm width x 130 cm height. Only adhesive tape can be used to mount posters. Material will be provided onsite. Please note that due to new EACCME regulations, authors are requested to disclose possible conflicts of interest on the poster. KEY WORDS If you would like to search for specific posters by individual keywords please use one of the following options: - the Abstract Book PDF on the USB device handed out to you together with your congress bag - the online program planner which is available on our website: www.eci-vienna2015.org - the mobile program app which is available for download in IOS- and Google Play Stores (search for ECI 2015) If you prefer a printed version of the abstract book you can purchase one (EUR 12.-) at the onsite registration desk in the entrance area of the congress venue. EFIS POSTER PRESENTATION AWARDS The EFIS proposes 12 Poster Presentation Awards for the best posters presented during the ECI 2015 in Vienna. The winners will receive a EUR 300,- cash prize. Poster Chairpersons will evaluate all posters presented during the guided poster sessions. Award Candidate Posters will be moved to a designated area (on the left when entering the exhibition / poster area) by the congress staff for further evaluation and will be displayed during all congress days. Final decisions on winners will be made by an award jury on Wednesday. Prizes will be awarded during the Closing and Award Ceremony on Wednesday, September 9, 17:45 – 18:45 hrs (Hall A). 2 Poster Presentations at the 4th European Congress of Immunology - ECI 2015 - Vienna, Austria Abstract Submission Statistics Country Abstracts Germany Austria United Kingdom Spain France Italy United States Brazil Turkey Australia Iran, Islamic Republic of Russian Federation Netherlands Switzerland China Poland Sweden Serbia Czech Republic Belgium Taiwan Hungary Greece India Korea, Republic of Ireland 439 311 229 186 172 148 105 102 79 75 75 73 68 65 63 50 48 44 40 37 37 35 34 34 34 27 Portugal Bulgaria Mexico Finland Algeria Croatia Ukraine Japan Tunisia Canada Singapore Slovakia Norway Denmark South Africa Chile Slovenia Romania Egypt Iceland Saudi Arabia Colombia Israel Thailand Argentina Hong Kong 27 26 24 23 21 20 20 19 18 16 14 14 13 12 12 11 11 10 9 8 8 6 6 6 5 5 Kenya Nigeria Oman Estonia Georgia Kuwait Latvia Lithuania Luxembourg New Zealand Zimbabwe Albania Benin Cameroon Costa Rica Indonesia Iraq Jordan Kazakhstan Libya Malaysia Morocco Pakistan Sri Lanka Uruguay Total 3 3 3 2 2 2 2 2 2 2 2 1 1 1 1 1 1 1 1 1 1 1 1 1 1 3013 500 450 400 350 250 200 150 100 50 0 Germany Austria United Kingdom Spain France Italy United States Brazil Turkey Australia Iran, Islamic Republic of Russian Federation Netherlands Switzerland China Poland Sweden Serbia Czech Republic Belgium Taiwan Hungary Greece India Korea, Republic of Ireland Portugal Bulgaria Mexico Finland Algeria Croatia Ukraine Japan Tunisia Canada Singapore Slovakia Norway Denmark South Africa Chile Slovenia Romania Egypt Iceland Saudi Arabia Colombia Israel Thailand Argentina Hong Kong Kenya Nigeria Oman Estonia Georgia Kuwait Latvia Lithuania Luxembourg New Zealand Zimbabwe Albania Benin Cameroon Costa Rica Indonesia Iraq Jordan Kazakhstan Libya Malaysia Morocco Pakistan Sri Lanka Uruguay Number 300 Country Poster Presentations at the 4th European Congress of Immunology -
