Some cytokines seemed more specific to cognitive aspects of the pathology as they were found deregulated in Alzheimer’s disease (AD) and FTD patients such as IL-11 (Galimberti et al., 2008), IL-15 (Rentzos et al., 2006b), and IL-12 (Rentzos et al., 2006a). The gene discussed is IL15; the disease is Alzheimer disease.
