英文摘要
Antibodies are ideal drug candidates due to their high specificity for target
molecules. Monoclonal antibodies represent one of the fastest growing segments of
the drug market, however, recent attention has focused on polyclonal antibodies
and monoclonal mixtures to reduce the opportunity for a disease to become drug
resistant. Polyclonal antibodies sampled from disease survivors or immunized
hosts offer a wealth of new drug candidates. Current pipelines for investigating the
immune response rely on hybridoma technology, which is time-‐consuming and does
not come close to mimicking the diversity of antibodies present in the organism.
Next generation sequencing of B-‐cells can deeply interrogate the immune response,
however, this technology falls short of providing insight into the best antibody drug
candidates.
We propose the development of Valens-‐Poly, which will integrate mass
spectrometry-‐based proteomics data with next generation sequencing of B-‐cells, an
emerging field called immunoproteogenomics. By interrogating the immune
response at the protein-‐level, Valens-‐Poly will be able to rank antibody sequences
based on their abundance, which is a proxy for specificity to the antigen of interest.
It is impossible to sequence all memory B-‐cells in a host organism, therefore the
antibody sequences reported would only represent a small fraction of the antibodies
that could be present. Using our patented spectral network approach, pioneered in
our monoclonal antibody sequencing tool, Valens, we will be able to recover
complementarity-‐defining regions (CDRs) of antibodies even when the B-‐cell was
not captured for next generation sequencing.
Finally, we will characterize the broad spectrum of antibodies produced as
part of the immune response, called the antibody repertoire. Identifying changes in
germline gene usage and tracking clone abundance and lineage in response to
immunization or across patients is an important component of characterizing
diseases and guiding drug discovery.
