They concern the increase of the FSC-A marker in the CD4+ T cell population in CVID and other PAD patients, the increase of the CD14 markers for a certain conventional dendritic cell population, the increase in CD8+ effector memory T cells and in CD8+CD45RO-CD31+ T cells and the decrease of certain gamma delta T cells in the other PAD and CVID patients. This evidence concerns the gene CD14 and common variable immunodeficiency.
