Antibodies and Complement Conference

The antibody response and the complement system are major effector arms of the immune system. Both have been involved in a plethora of pathological conditions, including autoimmunity, allergy, infections and cancer. Antibodies and complement components regulate, mainly through their receptors (FcR and CR respectively) cell activation, ADCC, ADCP, CDC, CDCP, migration, survival but also, as recently described, metabolism. As the portfolio of antibody—and complement-effector function grow, high-end technological solutions are developed and novel therapeutic applications are proposed.

This 2nd conference on Antibodies & Complement will focus attention on key advances in both fields with the aim at fostering discussions between antibody experts and complement experts. Some of the critical topics to be covered include:

  • antibody & complement (novel) functions
  • human antibody repertoires
  • complement structure and subcellular localization
  • novel technologies
  • complement and antibody therapies

After the success of the first edition, this second edition of conference on Antibodies & Complement should again be a forum for leaders in the field and new investigators coming from academia, industry and research institutes to discuss where the field is going and what challenges lie ahead.
