About

Plexision develops cellular biomarkers for personalized diagnosis and drug development in solid organ transplantation and immunological disorders. We also pioneer in R&D projects centered on integrating biomarker targets in all phases of drug development, from preclinical to post-marketing. Plexision’s technology can be adapted to

  • Assess disease risk for several immunological disorders.
  • Predict the success of a drug for a specific patient.
  • Develop dosing recommendations for new immunological drugs.

Our state-of-the-art laboratory is CLIA-certified and located in Pittsburgh, PA.

Mitogen stimulation

  • Mitogens are non-specific stimulants of immune cells.
  • Mitogen stimulation leads to immune cell activation and is used as a measure of general immune function. Common mitogens include phytohemagglutinin (PHA), phorbol-myristic-acid-calcium ionophore (PMA), pokeweed mitogen, and others.
  • Some mitogens have more pronounced effects on some immune cells than others. For example, T-cells are strongly activated by PMA, while B-cells are strongly activated by pokeweed mitogens.
  • Mitogen-stimulated immune responses serve as a positive control reaction in tests to measure antiviral immune cell function.
  • Healthy immune cells respond to stimulation with mitogens.
  • However, immune cells that respond to mitogens may not respond to other antigens.
  • Early during viral infections, immune cells fail to respond to the virus but may continue to respond to mitogens.
  • During immune deficiency, immune cells may fail to respond to viral antigens and mitogens.
  • Most individuals are exposed to common viruses during their lifetimes.
  • Cytomegalovirus (CMV) and Epstein-Barr virus (EBV) are two such common viruses.
  • The PlexCMV and PlexEBV assay measure T-cell immune responses to the CMV and EBV viruses.
  • Both tests also measure T-cell immune cell response to mitogens, simultaneously.
  • Selective loss of T-cell response to either virus is more common during infection with the corresponding virus.
  • Global loss of T-cell response to common viruses and mitogens is more often seen with immune deficiency.
