项目摘要
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.
抗体是理想的药物候选药物,因为它们对靶标具有高度的特异性。

从疾病幸存者或接种疫苗的患者身上采集抗药性的多克隆抗体。
东道主为他们提供了一大批新的新药候选人。目前的新药管道正在进行调查。
免疫反应依赖于杂交瘤技术,这是一项耗时的技术,也确实如此。
这离模仿人类有机体中存在的各种抗体的多样性还不是很近。
下一代B细胞测序技术可以深入了解人类的免疫应答。
然而,尽管这项新技术还不能为人们提供对世界上最好的抗体和药物的深入了解。

基于它们的丰度,这是检测感兴趣的主要抗原的特异性的一个重要替代指标。
要对寄主生物体中的所有非记忆B细胞进行测序是不可能的,因此也就不可能了。
