However, the conventional monitoring techniques are based on laborious, expensive methods. In the present work, it was evaluated the potential of an infrared spectroscopy based-method, in the assessment of lymphocyte T function after mitogen activation. It was possible to discriminate, either by principal component analysis either by hierarchical cluster analysis of second derivative spectra of lymphocytes T, between resting T cells and activated T cells. The infrared spectroscopy-based method presents therefore a high potential for a new diagnostic tool of the T cell alloreactivity.engT cellPhytohemagglutininInfrared spectroscopyconference object10.1109/ENBENG.2019.8692471
