The Human Leukocyte Antigen - Basic Immunological RolesLearn more about the role of the human leukocyte antigen (HLA) system in and beyond transplantation!
Please find the first part of our HLA Educative Series that targets a wide range of knowledge levels. We start with their basic immunology that will be followed by their roles in transplantation, and the genetics of HLA. As to the latter we will also cover how next-generation sequencing (NGS) is delivering accuracy and efficiency to HLA typing!

Omixon at ASHI 2015The ASHI event went smashingly for Omixon yet again, with a full soccer-sized team of 11 making the trip from all corners of the US and across the pond from Europe.
Omixon hosted four software training workshops on the Monday – the advanced workshops were particularly popular and the FAS team received excellent reviews from the attendees.
Tuesday saw the Lunchtime Symposium where Omixon had four guest presenters and CEO Tim Hague and CCO Peter Meintjes announced the results of the Holotype HLA Early Access Program.

T-Cell Receptor with HLA-A and Bound PeptideThe main role of Class-I HLA molecules is to present peptides on the cell surface to T-cell receptors (TCRs).
When a TCR interacts with a HLA protein (HLA-A*24 in the video), both the HLA-A amino acids (AAs), and other aminoacids from the
presented peptide make direct contacts to the TCR.
The presented peptides are usually small (8-10 AA long) fragments derived from proteins of the cell. These proteins are the "normal" ones building up the cells, and the presented small peptides everywhere on the the surface of each of our cells.
Once a pathogen (bacterium/virus) manages to enter to the cell, its peptides will also be presented on the cell surface. These peptides are expected to be different from the host's peptides (as proteins building up viruses and bacteria are different) the pattern on the surface of the HLA protein will be also different - this is what the T-cell receptor will recognize as "foreign".
On this animation the 3VXR crystal structure shows that principal interactions in the HLA-peptide-TCR complex. You can see that the peptide (a piece from the HIV virus) is not completelly buried in the HLA-A protein, there are amino acids dangling into the intercellular space, and these can make direct interactions (H-bonds, pi-pi stackings, van der Waals) with the corresponding amino acids of the T-cell receptor. There are important water molecules as well, these are not visualized to make the picture less cluttered.
These interactions are governed by the density of electrons around different atom types. The electrostatic potential around this ramified structure can be estimated using Poisson-Boltzmann electrostatics, and visualized by PyMOL. Amino acids building up proteins are generally polar molecules (though many has apolar sidechains), therefore when calculating electrostatic potentials, one have to consider the polar water molecules solvating the protein. Electrostatic potential differences in the binding region depict those patterns that are responsible for the binding of the HLA and TCR molecules. Most of the surface shown is gray (water is surrounding the proteins) the colourful patterns in and around the binding cleft are what a T-cell receptor can recognize as an epitopes.

EFI 2015 - Success for AllApril 2015, Omixon had a tremendous experience in the amazingly picturesque city of Geneva Switzerland – the backdrop for EFI 2015, facilitated by Prof. Jean-Marie Tiercy and Dr. Jean Villard and their team of professional event managers.
Our booth was buzzing continuously with technical repartee and multiple software demos, and many participants were very interested in our NGS genotyping solutions for HLA. To further demonstrate Holotype HLA’s performance, Omixon held a series of three 1-hour workshops on Sunday April 26, for several HLA field experts to practice using our HLA Twin software hand-on in a class-room-environment, pampered by our support colleagues, Efi Melista (Field Application Scientist) and Agnes Pasztor (Customer Support Manager).
The activity in our booth and workshops was complemented by the Omixon Symposium on Monday April 27, attended by over 100 professionals from the HLA community. Introductory presentations from Marcello Scala (Sales Manager, EMEA & Asia) and Tim Hague (CEO) were followed by personal reports from some of our evaluators, presented by guest speakers Lydie Brunet (Geneva University Hospital), Mette Christiansen (Aarhus University Hospital, Denmark) and Amalia Dinou (Biomedical Foundation of Academy of Athens, Greece) – thank you again to our special guests for talking at our event!
The fun did not stop there – Omixon continued to entertain attendees with a number of side-shows, such as our wine-tasting event (“Cheers”), scientific posters sessions (3 posters), and a comic-posters lucky draw (winners to be announced soon).
Thank you again to the EFI 2015 organisers, we certainly look forward to seeing you in Kos, Greece for 2016.

Omixon at ASHI 2014Omixon attended ASHI (The American Society for Histocompatibility & Immunogenetics) in Denver, USA, October 20 to October 25, 2014. The event was extremely successful, with both the HLA Twin ‘Novel Allele Discovery’ Workshops and the Holotype HLA Luncheon oversubscribed, with the Omixon booth occupied with interested attendees all day. Omixon was also featured in five posters and three scientific talks from prominent speakers.
The Luncheon event saw the launch of Omixon’s new Holotype HLA combined assay and software product, including three guest speakers from Early Access Program labs – Laurine Bow from Yale, Julio Delgado from ARUP and Medhat Askar from Cleveland Clinic – plus speeches from Dimitri Monos (from The Children’s Hospital of Philadelphia) and Peter Meintjes and Tim Hague (both Omixon).
