-28th Meeting on Signal Transduction
CellCommSummit 2025
November 3 - 5 - Leonardo Hotel Weimar
Jointly organized by:
As in previous years, the 28th STS Meeting will be organized as a Joint Meeting of the Signal Transduction Society 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). If other organizations are interested in joining future STS Meetings, please contact the STS President Prof. Dr. Katharina Hieke-Kubatzky.
Workshops 2025
Planned Workshops:
A) From Basics to Translation
B) Hot Topics in Signal Transduction
C) Immune Cell Signaling
D) Infection and Inflammation
E) G-Proteins, GPCRs, and Ion Channels
F) Tumor Cell Biology
G) Differentiation, Stress, and Death
H) Growth factors and Neural Signaling
Program
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 1, 2025).
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.

Farewell Snack / End of Meeting
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.
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.
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.
Prizes and Travel Grants
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 2025, 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 2025, the STS will 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 transfer, provided that the prize winners attend the award ceremony in person.
Sponsors of the STS Meeting
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.
