Interest Group Invitation

ISSFAL invites Interest Group proposals at the 2018 biennial meeting in Las Vegas.   This is an opportunity to have small group meetings on specialized topics for in-depth discussion, peer formation, particularly for younger generation professionals including students, and first-hand information sharing.  Lipid-related basic and clinical research topics are welcome. 

Once the proposals are accepted, they will be posted on the web-page to attract participants.  Any interest group with minimum 15 participants will be offered a meeting room with podium and desserts/refreshments on Tuesday May 29th starting at 7 pm.   

A one-paragraph proposal describing the background and justification should be submitted to Hee-Yong Kim at hykim@nih.gov


Challenges in lipid trafficking and metabolism

Hosted by: Chuck Chen, United States of America; Blake Hopiavuori, United States of America; and Kevin Lin, United States of America

A major challenge we face as lipid biologists, is the inability to accurately and reproducibly track lipids as they are trafficked intracellularly. Cellular membranes have unique lipid profiles, but for example, how do cells distinguish between a 26:0-containing (dihydro) ceramide and a 22:6n3-containing phosphatidylcholine? Are there unique chaperones for specific lipids? How are lipid molecules recognized by such chaperones? Is it based on the electron cloud signature of a specific lipid or purely structural configurations?

Similar to proteins, the objective of the Lipid Trafficking Interest Group is to target, track, and identify unique lipid molecules to better understand how lipids are involved in various pathological conditions. A better understanding of lipid biochemistry may be the key to understanding the most complicated human diseases. Come share your thoughts and ideas with us as we embark on this complicated yet exciting journey. Refreshments will be served.


Lipidomics Special Interest Group

Hosted by: Juan J. Aristizabal Henao, Canada and Alexander Sorokin, United States of America

Lipidomics requires advanced expertise in lipid metabolism and analytical chemistry. Rapid changes in technology, such as mass spectrometry instruments and software to process the data add to the challenges in the field, particularly for graduate students.  The use of lipidomics can provide unique insights into the various influences on lipid biology such as nutrition and genetics and help elucidate metabolic pathways in the study of health and disease.  This session will provide a place where graduate students, young professionals and researchers can talk frankly about their experiences with lipidomics and some of the challenges they have encountered.  The forum would be open, but could entail discussions on types of analytical approaches, sample preparation, challenges with quantitation, and identification of lipids species in untargeted analyses.  In addition, the forum would be interested in discussions with individuals looking to make the leap from fatty acid composition type analyses to lipidomic analyses that identify the acyl/alkyl species of complex lipids in their naïve form.


Fatty acid balance in food oils and fats

Hosted by: Patricia De Velasco, Universidade Federal do Rio de Janeiro, Brazil; Sally Draycott, University of Adelaide, Australia; and Ella Baker, University of Southampton, United Kingdom

Additional Participation:  
Dr. Xue Bing Xu,  Wilmer Corporation, China
Dr. Tom Brenna, University of Texas, USA

Food oils derived primarily from vegetable sources constitute the majority of visible fats in the diet, and therefore form the base lipids driving human physiology.  High linoleic acid seed oils for instance - soy, rapeseed/canola, sunflower, safflower – became a dominant oil source in the 20th century.  The 21th century has seen transitions to oils modified for fatty acid content, notably high oleics with lower linoleic acid more consistent with common fruit oils such as olive and palm oils, as well as reductions in partially hydrogenated oils.  Oil blending to achieve consumer acceptance and particular fatty acid compositions is widely practiced, especially in China. This new interest group will discuss nutritional issues around food oils aimed at identifying research topics arising with the contemporary and emerging knowledge of fatty acid metabolism, genetics of fatty acids, and at the interface of oil supply and production.
