Modelling CLL cell and T-cell Migration in a Dynamic Circulating Model of CLL
Elisabeth Walsbyl, Paul Brennan', Guy Pratte, Andrea Buggins3, Tanja N Hartmann'', Chris Fegan1 and Chris Pepper'

We have recently developed a novel circulating model of chronic lymphocytic leukaemia (CLL) that mimics the transient interactions that take place between circulating lymphocytes and vascular endothelium. Here we show that both normal and malignant lymphocytes actively underwent transendothelial migration.

Quantification of Natural Killer Cell-Mediated Cytotixicity using Celigo Imaging Cytometry
Leo L. Chan, Srinivas S. Somanchi, Kelsey Rosbach, Dean A. Lee

Time-course tracking of % lysis eliminates multiple controls & the effect of non-uniform cell seeding in the final cytotoxicity calculation. The # of cells used is less than the cells needed for Release assays & Flow Cytometry. Flow cytometry & Release assays require a seeding density of 100K target cells increasing the number of effector cells to the millions. The visual observation of ADCC or CDC on the images can be convincing to conclude the functionality of antibodies or complements.

THE MASTOCYTOSIS SOCIETY SURVEY ON MAST CELL DISORDERS: Part 2-Clinical Experiences, Co-Morbidities, Diet, Families and Opinions
aNancyRussell, DrPH, aSusanJennings, PhD, aBlairJennings, BS, aValerie Slee , RN, BSN, aLisa Sterling, BS, bMariana Castells, MD, PhD, FAAAAI,cPeter Valent, MD, bCem Akin, MD, PhD, FAAAAI

Mast cell diseases such as mastocytosis and mast cell activation syndromes involve abnormal proliferation or activation of these cells leading to many potentially debilitating symptoms. In order to determine the characteristics and experiences of people known or suspected to have a mast cell disorder, The Mastocytosis Society (TMS), a U.S. based patient advocacy, research and education organization, conducted a survey of patients.

Safety Of A Sublingual Tablet of House Dust Mite Allergen Extracts In An Environmental Exposure Chamber Study
Michel Roux, Agnès Viatte, Robert K. Zeldin

In an environmental exposure chamber (EEC) study, treatment with HDM sublingual tablets in patients with HDM-associated allergic rhinitis was generally well tolerated regardless of dose. While asthma and related symptoms were more common during the peri-EEC challenge periods, rates did not differ between active and placebo treatment.

Safety Of The 300 IR and 500 IR Doses Of A House Dust Mite Allergen Extracts Sublingual Tablet In Adults with Allergic Rhinitis
Hélène Nguyen, Michel Roux, Josiane Cognet-Sicé, Robert K. Zeldin

In a randomized, DBPC study in patients with HDM-associated allergic rhinitis, treatment with HDM sublingual tablets at doses of 300IR and 500IR was associated with a favorable safety profile. There was no appreciable difference in tolerability between the tested doses.

Field Performance of a New Technology with the Potential to Identify Allergy and Asthma Triggers
Julian Gordon, PhD, Prasanthi Gandhi, MBA, MPH1, Jack A.Gilbert, Jarrad T. Hampton-Marcell

This work introduces a very simple plug-and-play device that can sample air at a high volume flow rate with no moving parts. Aerosol particles are captured on electrodes and eluted for testing. We show that performance of the device is substantially equivalent to capture by pumping through a filter for immunological and molecular analysis.
