As in previous years, sponsoring companies will have the opportunity to present their innovative products for signal transduction research as a 15 min plenary lecture in a Workshop session. These presentations will conclude the Workshop sessions to allow for further discussions with the companies’ representatives at their booths during the following breaks.


Each Workshop/Session will start with introductory keynote presentations of 30 minutes (including discussion) given by invited speakers who have contributed significantly to the development of specific areas of signal transduction research. Keynote speakers are nominated by STS members and contributing consortia.

All presentations will be given as plenary lectures in the main conference hall. There will be no parallel workshop sessions. Oral presentations will be selected from the submitted abstracts (abstract submission deadline: September 24, 2023).

A limited number of abstracts will be selected for oral presentation of 10 minutes plus 5 minutes of discussion. The oral presentations are thematically related to the Workshop topics. They will be selected by the organizing committee on the basis of scientific quality and consistency with the scientific program.

Congress Venue

The STS Meeting will again take place in the Leonardo Hotel Weimar, located in the world heritage city of Weimar, Germany.

Leonardo Hotel Weimar

Belvederer Alle 25 - 99425 Weimar

Accomodation rates at the congress hotel are usually quite low as compared to other hotels located in the city centre. You can reach the congress venue starting from the central train station by bus (line 1 / direction Ehringsdorf --> get out at "Falkenburg" bus stop) or by taking a stroll (takes you about 40 minutes).

If you travel by car, you may either choose to park at the hotel's own parking lot or parking garage (charges apply) or search free parking space in the adjacent streets.

Abstract Submission

The deadline for abstract submission was September 24. Changes can still be made - please contact the webmaster.

By 13 October 2023 at the latest, you will be informed by e-mail about further details, e.g. date, time and type of presentation (if you have chosen "Talk or Poster").

Poster Sessions

All accepted poster contributions will be on display (poster format: DIN A0, upright, 84,1 cm x 118,9 cm) throughout the Meeting in an assigned poster area together with the sponsors’ exhibition. This comfortable area can be used for vivid discussions at the posters during the coffee breaks. Ample time will be reserved for poster viewing and discussion.

“My Poster in a nutshell" presentations

In addition, all accepted posters can be presented to the plenum in one of the Short Talk Sessions as a concise One-Minute-Short talk. Please prepare one PowerPoint Slide containing key aspects of your scientific contribution to attract participants to your poster. After the short talk presentation it will be possible to meet at the posters for further scientific disussions.

STS Honorary Medal 2023

The STS honorary medal represents the most prestigious award of the STS. The medal is presented every year to an outstanding scientist who inspired scientists all over the world to work on receptors, mediators or genes involved in signal transduction processes. The Medal Ceremonies with informative Laudations and the Medal Award Lectures are meanwhile established highlights of the conference.

A list of Past Recipients of the STS Honorary Medal is available.

Prizes and Travel Grants

Application Deadline

The deadline for all applications (travel grants, GBM-Innovation-Award, STS Science Award) is 17 September 2023!

STS Science Award

This prize is meant to honor outstanding research by a post doc or a junior principal investigator being member of the Signal Transduction Society. In 2023, the STS Science Award will be donated with a sum of 1500,- Euro.

The jury board consisting of the STS council and STS advisory board members will evaluate the applicants’ scientific achievements and background in general and discuss the meeting contributions in detail in order to finally take their decision on the awardee.

GBM-Innovation-Award for Young Scientists

Each year on the occasion of the STS Joint Meeting “Signal Transduction - Receptors, Mediators and Genes”, the Society for Biochemistry and Molecular Biology/Gesellschaft für Biochemie und Molekularbiologie e.V. (GBM) announces the GBM-Innovation-Award for Young Scientists, donated with EUR 500,–.

The prize will be granted to a young scientist (diploma, master, MD or PhD student or post doc within their first years) who is developing or has developed a novel and innovative method, which might be attractive for all of us. The work has to be submitted as an abstract to the STS-Meeting and must be presented also as a poster, even if the abstract is selected for oral presentation. The awardee will be announced at the Award ceremony. Awards can only be received personally.

The award jury consisting of the speakers of the GBM-Study Groups “Biochemical Pharmacology and Toxicology” and “Receptors and Signal Transduction” will select appropriate candidates.

STS travel stipends

In 2023, the STS decided to award ten young scientists travel stipends (300 EUR each).

For more details, please also refer to the Prizes / Travel grants section of our website.

Poster Prizes

Five poster prizes will be awarded during the meeting. The candidates will be selected by the chair people of the different sessions.

The prize money will be paid by bank transer, provided that the prize winners attend the award ceremony in person.

Company Raffle

The participating companies have again generously sponsored prizes. All you have to do to win one of them is go to the company booths and talk to the representatives. For this you get a sticker with the logo of the company, which you put on the entry form enclosed in the booklet. The more stickers collected, the higher the chance of winning one of the coveted prizes. The sheet can then be dropped into the lottery box set up at the registration desk or handed in to the staff there by 9 a.m. on Wednesday, 6 November 2024 the latest.

The prizes will be awarded on Wednesday between the last two workshops of the meeting.
