Overview

This protocol will be used to collect crucial components of the immune system from healthy volunteers for the characterization of immune cells in fresh blood. A pipeline has been set up for comprehensive immune phenotyping of both lymphoid and myeloid cells within 24 hours after blood withdrawal.

Detailed description

In order to properly compare the immunobiology of healthy volunteers to (advanced) cancer patients, the investigators use age-matched controls with no history of cancer and no potentially interfering medication.

Healthy volunteers will be asked to donate 5 tubes of blood

Interventions

  • Other Blood sample
    Blood sample

Primary outcome measures

  • The number of immune cells, both lymphoid and myeloid, present in the blood of healthy individuals, assessed by flow cytometry, as well as cytokine expression and transcriptome profiles of these cells [Time frame: assessed up to 12 months]
Secondary outcome measures (1)
  • Immunophenotyping of both myeloid and lymphoid cells in healthy individuals [Time frame: assessed up to 12 months]

Eligibility criteria

Inclusion criteria

  • Age above 35 years
  • Written informed consent

Exclusion criteria

  • Fever 14 days before blood withdrawal
  • Donated blood for the same program within the last 2 years
  • Pregnancy
