The title of this paper is:
CD4+ T-cell immunity in the peripheral blood correlates with response to anti-PD-1 therapy.
In this paper, the authors conducted clinical trials to calculate the frequency of CD62Llow CD4 T cells and regulatory CD4 T cells in the blood of lung cancer patients using the algorithm they have developed and they have discovered that they can well predict the onset of therapy with an immune checkpoint inhibitor of anti-PD-1 antibody before administration (decided to grant a patent). They also studied characterization of CD62Llow CD4 T cells in those patients. Importantly they noticed that the same algorithm can be used for predicting patients with long-term survival of 500 days or more. From these data, Professor Kagamu et al. concluded that it is important to monitor the status of CD4 T cells in the blood to determine treatment strategies for cancer patients.
