Workshops 2023

Planned Workshops:

  1. Immune Cell Signaling

  2. Special Workshop: 25 years of STS

  3. Hot Topics in Signal Transduction

  4. STS / CIBSS joint workshop:
    From Basic Research to Innovation

  5. G-Protein Signaling

  6. Differentiation, Stress, and Death

  7. Tumor Cell Biology

  8. Infection and Inflammation

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.

End of Meeting

Registration and Fees

The STS aims at making the meeting attractive and affordable especially for young scientists.

As in recent years, the regular meeting fees cover lunches, dinners (without beverages) and catering during coffee breaks and poster sessions throughout the meeting. Moreover, the conference book and the traditional personalized STS coffee mug are also included in the registration fees.

Please note that accomodation costs are not included in the meeting fee, so you are free to arrange bookings by yourself.

Register here for the meeting!

We would like to stress that the fees for STS members do not even cover the effective costs for individual participants.

Congress Venue

The 26th 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.

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.

Abstract Submission

The deadline for abstract submission is currently set to September 24. After logging in to the password-protected area of our website (upper right corner of the website or "burger" menu on mobile devices), creating and submitting an abstract is easy: select "My Abstracts" on the left-hand side and add an abstract (3000 characters maximum for main text) by clicking on the "+Add abstract" button. You can revise this abstract as a draft as often as you like. After clicking on "Submit", the abstract is finalized and can no longer be edited. In this case, however, 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").

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 2023

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 2023

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.

Sponsors of the STS Meeting 2023

The industrial exhibition of sponsoring companies will take place in an approximately 400 square meter area together with the poster exhibition in order to concentrate and facilitate interactions between the conference participants and the industry.

We are very grateful to all companies who want to support the STS Meeting.

If you are interested in sponsoring the meeting, please contact Katharina Hieke-Kubatzky.

Sponsors of the meeting as of 19.09.2023 are:


The STS is a non-profit organization that currently represents around 350 scientists. Over the past years, we have developed a fairly efficient and cost-saving routine for the Meeting organization. The Meeting is organized as a Joint Meeting of the STS with signaling study groups of the German Societies for Immunology (DGfI) and Cell Biology (DGZ), the Society for Biochemistry and Molecular Biology (GBM), the German Society for Pharmacology (DGP), and the Collaborative Research Center "Structural Dynamics of GPCR Activation and Signaling" (SFB1423). This year, we are delighted to welcome the Centre for Integrative Biological Signalling Studies (CIBSS) as new co-organizer of the meeting.
