    Nanowell approaches to measuring mucosal immune responses

  • Sample Size! Cost/Sample!


    1,000,000! 1,000 -! 100,000!

  • Integrated single-cell analysis for clinical monitoring

  • Software tools for data extraction and analysis


    J. Proteome Res, 2014

    Microarray data extraction


    Image cytometry data extraction

    •  # cells/well •  MFI per channel •  X-Y coordinates •  Well address


    Data integration & analysis

  • Some questions: •  What are homing signals? •  Survival signals in tissue? •  Critical effector functions?

    T cell biology in female genital tract – many aspects still require further characterization

  • Nanowell-based process to analyze cervical leukocytes

    Advantages •  Minimal sample handling (single centrifugation step) •  Iterative analysis for deep phenotyping

    Isolate sample

    Label and deplete RBC &


    Directly load sample Label cells

    Image Activate & Microengrave


  • Deep phenotypic analysis of cervical CD45+ cells using MuSIC

    T. Gierahn, unpublished

  • Cervical CD4 T cells express CD69, but few are CD103+

    T Resident Memory Central/Effector Memory



  • Lessons learned for analysis of mucosal samples using nanowell-based technologies

    •  Less is more –  Minimal sample handling –  Direct processing in microtechnology –  1,000 cells – no problem

    •  More is better –  Fresh preferable (viability) –  Rare cells are still rare—sampling from finite numbers –  Multiple hypotheses for rare states limiting with few cells

    •  Better is better –  Open the spotlight – integrated measures of molecular profiles –  Embrace multidimensional analyses to generate hypotheses –  Minimize numbers of samples required from patient
