While GPCRs (G protein-coupled receptors) are important therapeutic targets, it has been challenging to discover therapeutically relevant antibodies against them.  This course will examine different steps along the anti-GPCR antibody discovery pathway and highlight various approaches to accomplishing each step.  The topics to be covered include: antibody discovery, including methods to generate antibodies and antigen preparation; assays to evaluate antibody binding using cells expressing the GPCR of interest; and in vitro assays to measure functional activity of the antibody, including antagonism, agonism, or synergism/allosteric modulation using  chemotaxis, calcium, cAMP or other cell-based assays; and 4) review of promising GPCR targets and therapeutic antibodies currently in  clinical development.


The material to be presented in this short course includes:

  • Brief review of GPCRs, including structure, mechanism and role in diseases such as cancer, inflammation and metabolic disease
  • Methods for antibody discovery
  • in vitro assays for antibody characterization
  • Review of relevant kinetics, including agonism, antagonism and allosteric modulation
  • Review of GPCR-targeting antibodies in the clinic
  • Open discussion
