SC9: Targeting of GPCRs with Monoclonal Antibodies
Monday, September 19, 2016 3:30 - 6:30 pm
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: 1) antibody discovery, including methods to generate antibodies and antigen preparation; 2) assays to measure antibody binding, such as an EC50 using cells expressing the GPCR; 3) in vitro assays to measure functional activity of the antibody, including antagonism (IC50) or agonism using chemotaxis, calcium, cAMP or other cell-based assays; and 4) review of promising GPCR targets and antibodies in the clinic.
The material to be presented in this short course includes:
- Brief review of GPCR’s, 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
