Wellderly Immune Antibodies Study, a Sub-Study of Healthy Elderly Active Longevity (HEAL) Cohort

The aim of this sub-study is to determine whether the Wellderly posess neutralizing antibodies targeting antigens involved in chronic disease. The humoral immune system is well known to produce anti-cancer and other antibodies that can be long lived in vivo. In this study we will evaluate the antibody status of the Wellderly with respect to neutralizing (i) molecules known to induce cholesterol like PCSK9, (ii) antibodies against cancer antigens like PMSA (prostate cancer) or Her2 (Breast cancer), (iii) antibodies against inflammatory molecules like TNFa or IL-6, (iv) antibodies that have broad neutralizing activity against infectious diseases like influenza.
