The conference was attended by more than 200 scientists and clinicians from 18 different countries, including persons from Canada, China, the Czech Republic, England, France, Germany, Hungary, Israel, Italy Japan, Mexico, Norway, Poland, Russia, Slovakia, Spain, Sweden, the Ukraine, and the United States.

Outcomes of the Workshop

The provisional list of "new" CD molecules is in the table below.

The validation files for the new CDs can be accessed from the "Cell Surface Molecules" tab.

Validation files for antibodies to intracellular antigens analysed durign the HLDA9 Workshop can be accessed from the "Intracellular Antigens" tab.

Data for other submitted mAbs will be posted during the forthcoming months at the HLDA Workshop webpage.

HLDA9 / Barcelona

The 9^th International Conference on Human Leukocyte Differentiation Antigens (HLDA9) was held at the Fundació Academia de Ciencies Mèdiques i de la Salut de Catalunya i de Balears in Barcelona, 11-13 March 2010. In attendance were more than 200 scientists and clinicians from 18 different countries, including persons from Canada, China, the Czech Republic, England, France, Germany, Hungary, Israel, Italy Japan, Mexico, Norway, Poland, Russia, Slovakia, Spain, Sweden, the Ukraine, and the United States.

I would like to express my sincere thanks to all of you who attended and contributed to HLDA9. I was extremely pleased with the high quality of the work shown at all levels – from posters to special session oral presentations to plenary talks. It was also encouraging to see so many of you at the Gala Dinner.

More importantly, as someone who has attended nearly all of the HLDA Conferences, it was rewarding to see so many young scientists, from many different nations, participating and building upon the work begun nearly 30 years ago.

Validation files for the new CDs and other submitted antibodies

For those of you who are interested, validation files for the new CDs, as well as other submitted mAbs (including those against intracellular molecules) will be posted during the forthcoming months at the HLDA Workshop webpage (www.hlda9.org).

We hope to greatly expand and enhance this site over the next year to make it a very worthwhile destination not only for those working in this field, but also for researchers in other disciplines.

Validating new CDs

As Dr. Boumsell mentioned in her closing plenary talk "Perspective on Future Developments", HCDM-HLDA plans to make the submission of antibodies readily available to researchers year-round, and not just at the international workshops/conferences held every 3 to 5 years.

More information will be forthcoming on this once a submission procedure has been established.

For all of these future developments, we encourage you to bookmark and visit the HLDA Workshop page (www.hlda9.org).

Again, thank you all for participating and contributing to HLDA9. It is you who have made it such a success. I look forward to interacting and working with you again in the near future.
