IIVS at SOT 2018

February 8, 2018
IIVS will have several events and posters at the upcoming SOT meeting, March 11-15, in San Antonio, TX.  The events and three of our five posters focus on our respiratory toxicology program in support of our new laboratory that opened in 2017.  Other posters examine topics in phototoxicity.  Be sure to visit our booth at the meeting - Booth #533.   View more details on our events and posters at SOT....

In Vitro Exposure Systems and Dosimetry Assessment Tools for Inhaled Tobacco Products: Workshop Proceedings, Conclusions and Paths Forward for In Vitro Model Use

August 17, 2017
In 2009, the passing of the Family Smoking Prevention and Tobacco Control Act facilitated the establishment of the FDA Center for Tobacco Products (CTP), and gave it regulatory authority over the marketing, manufacture and distribution of tobacco products, including those termed ‘modified risk’. On April 4-6, 2016, IIVS convened a workshop conference entitled, In Vitro Exposure Systems and Dosimetry Assessment Tools for Inhaled Tobacco Products, to bring together stakeholders representing regulatory agencies, academia and industry to address the research priorities...

Awards of VITROCELL In Vitro Inhalation Exposure Systems

June 30, 2017
The PETA International Science Consortium (PISC) awarded four VITROCELL in vitro exposure systems to researchers from institutions in the UK, US, and Belgium who are leading the development of non-animal methods to test the toxicity of airborne substances. IIVS is grateful to PISC for donating the VITROCELL System for use in its new respiratory toxicology laboratory. The new lab provides  non-animal testing services for evaluating potential respiratory hazards associated with novel ingredients and chemistries used in fragrances, personal care products, household and institutional cleaning...

Using In Vitro Assays, the Direct Peptide Reactivity Assay (DPRA), KeratinoSens™ Assay (KS), and Human Cell Line Activation Test (h-CLAT) to Assess Skin Sensitization Potential of Electronic Cigarette Liquids

April 4, 2017
Three regulatory accepted in vitro assays were evaluated in a proof-of-concept project to determine skin sensitization potential of electronic cigarette liquids (eliquids). These assays measure molecular initiating events and initial cellular responses prescribed in the OECD Integrated Testing Strategy (ITS) describing key events in the adverse outcome pathway (AOP) leading to skin sensitization....

Assessment of In Vitro COPD Models for Tobacco Regulatory Science: Workshop Proceedings, Conclusions and Paths Forward for In Vitro Model Use

March 30, 2017
On 8-10 December 2014, IIVS organised a workshop conference, entitled Assessment of In Vitro COPD Models for Tobacco Regulatory Science, to bring together stakeholders representing regulatory agencies, academia, industry and animal protection, to address the research priorities articulated by the FDA-CTP. Specific topics were covered to assess the status of current Assessment of In Vitro COPD Models for Tobacco Regulatory Science technologies as they are applied to understanding the adverse pulmonary events resulting from tobacco product exposure, and in particular,...

Precision Digital Dispensing of Patterned Picoliter Quantities of Test Material onto Apical Surfaces of Human 3D-Reconstructed Airway Tissues

March 30, 2017
There is an increasing need for researchers to understand the dynamic aspects of inhaled tobacco product exposure. Available 3D human reconstructed airway tissues (RHuA) provide researchers with a more physiological platform that offers apical and basal compartments for flexibility in modelling relevant exposures. We have tested the Tecan D300 digital dispenser as potential technical solution to deliver precise amounts of very small vehicle droplets to coat the apical surface of an available RHuA....
