    Dear Fellow Complementologists, 

    In the last two years, we have been witnesses to the worst pandemic in more than a century. The loss of life and health, and the economic and social disruptions that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has brought and still brings are devastating across the globe and will resonate through societies for years to come. But the COVID-19 pandemic also showed what we can achieve when we come together: the development of vaccines against SARS-CoV-2 has occurred with unprecedented speed, with several vaccines approved and billions of doses administered worldwide with exceptional speed.

    Although the immunological sciences have, as a consequence, gathered much public interest and support, the last two years have nonetheless been hard on our trainees. Not only have work and travel restrictions negatively impacted their primary research outputs, but they also severely muted another vital part of their training experience, specifically the ability to meet other scientists in person, directly share and discuss their work, and lay the foundations for their future peer group networks.

    Innovation and the “can-do” attitude of members of our field have nevertheless permitted us to weather some of these difficulties. As a result, we had the privilege of still enjoying some outstanding virtual meetings over the last two years. In particular, the organizing committee of the 28th International Complement Workshop in Berlin needs to be congratulated on pioneering the virtual format of our flagship meeting.

    It is, however, safe to say that we all long for a substantial in-person meeting. It therefore gives me great pleasure, in the name of the local organizers Claire Harris and Kevin Marchbank, to invite you to the 29th International Complement Workshop in Newcastle, UK, September 1-5, 2023. The UK has a rich and long history of complement research. Newcastle, in particular, is recognized as powerhouse of innovation because of the pivotal contributions of the complementologists at Newcastle University to our understanding of the mechanisms and treatments of complement-mediated thrombotic microangiopathy (also known as atypical haemolytic uraemic syndrome). The University is excited to host the 29th ICW and has committed substantial funds to support and provide a state-of-the art and ecofriendly conference setting. Paired with the city’s rich history and local hospitability, Newcastle should provide an excellent platform for a vibrant and exciting meeting on complement. Over the last few years, it has become clear that complement serves unexpected roles in cell physiology and immunology – in fact, complement has emerged as an important contributor to the pathology of COVID-19. Thus, there is renewed interest in this ancient system and this meeting will be a stellar opportunity for colleagues and collaborators, as well as newcomers to the field, to learn about and to discuss broad aspects of complement biology.

    I hope to meet you in Newcastle 2023.

    It’s undoubtedly safe to say that we had all hoped for a better start to 2022. Despite all that is going on around us in the world, I’d like to take this opportunity to wish you, your colleagues, your families and friends a healthy, happy and prosperous New Year 2022.

    I greet you as the new president of the International Complement Society. As most of you know, I began my training in complement over 20 years ago. I have had, and continue to have, the privilege of being mentored by, and working with, some outstanding scientists. These individuals formed me as a researcher and individual.

    During the last 20 years I have witnessed how our understanding of the complement system has morphed from that of a sidekick “complementing” the rest of the immune system into that of a primary orchestrator of immunity, cellular physiology and tissue homeostasis.

    My enthusiasm for this old system has not waned over the past decades. Quite the opposite, in fact, since  I could not envisage working in another field. Thus, I thank you for your trust in allowing me to lead the ICS as president for the next two years.

    I am fortunate that I can tap into the experience of an outstanding ICS leadership team. Peter Garred’s contributions as past president have been invaluable. Specifically, his early initiative during the COVID-19 pandemic allowed us to weather some of the difficulties faced by a scientific community living through a pandemic. Over the last two years we have had the privilege of enjoying two outstanding virtual symposia on the roles of complement in COVID-19 and in inflammation spear-headed by the ICS. 2021 ended on a high note, with the highly successful 28th (virtual) International Complement Workshop organized by Peter Zipfel and Christine Skerka and their Local Organizing Committee; this conference created much needed opportunity to make new friends and reminisce with old ones, meet colleagues and collaborators, discuss science and to network.

    I am excited to also have the support of the new president elect, Trent Woodruff, the new ICS secretary, Zoltan Prohaszka, council members Nobutaka Wakamiya, Leendert Trouw, Josh Thurman, and Claire Harris, as well as newly elected members Suzan Rooijakkers, Rafael Bayarri Olmos, Anne Rosbjerg, and Lubka Roumenina. I am delighted that my tenure coincides with the term of Viviana Ferreira as newly elected treasurer. Viviana and I have worked together on several occasions for the ICS mission, and she has been instrumental in increasing the visibility of complement research among the broader immunology community via her engagement with the American Association of Immunologists.  

    We would like to put on record our gratitude to Michael Kirschfink and Dan Ricklin whose tenures ended in 2021 and who left the ICS in good (financial) shape. We will miss their insights and their contributions. Another loss for the ICS leadership is the retirement of our executive director and stalwart, Sheilah Jewart. Sheilah’s expertise, intuition, and diplomatic streak brought important and needed change to the operations of the ICS. Her contributions to keeping our ship afloat were invaluable and will be missed. In her place, we welcome Karen Gottlieb as new ICS executive director. Karen comes with the highest possible endorsement from Sheilah, and I am confident that she will be an excellent successor.

    Thus, the ICS Board and I, with engagement from ECCO, and in dialogue with the complement community, are looking forward to further promoting the complement system as a critical player in immunology and as a therapeutic target – and to ultimately recruit and retain the best and brightest of young researchers to join our exciting field and to become the leaders of tomorrow.

    Claudia Kemper, President

    Dear Colleagues:

    On behalf of the officers and councilors of both ICS and ECN, we want to thank you for your patience and understanding while we worked out responses to the SARS-CoV-2 pandemic, that caused the cancellation of the ICW Berlin 2020. After much discussion of the options available, it was agreed it would be in everyone’s and both societies best interest and to move all three forthcoming complement meetings up a year. We will announce further details once we have the new dates finalized for ICW Berlin 2021 / EMCHD Bern 2022 / ICW Newcastle 2023.

    This also impacts the  ICS Council nominations and elections as we move forward. To comply with the Bylaws of ICS the elections will be postponed and will follow the regular order in 2021. The ECN board has decided to follow the same procedure. 

    In response to the pandemic, ICS/ECN will be holding a series of meetings via Zoom to address the issues around complement and Covid-19 and open a discussion forum on Slack. Information about new articles related to complement and Covid-19 will be posted on and discussed in Focus on Complement. Look for the announcement in the next couple of days and plan to participate in these important knowledge-sharing opportunities and possibilities for collaborations, which will be done in partnership with the early-career complementologists, organized in ECCO (chaired by Dr. Nicole Schäfer).

    ​Best Regards,

    ​Peter Garred, MD, DMSci                 Reinhard Würzner, MD, PhD,

    President of ICS                                 MD, PhD, President of ECN
