Alzheimer's disease is a debilitating age-related disorder characterized by distinct pathological hallmarks, such as progressive memory loss and cognitive impairment. During the last few years, several cellular signaling pathways have been associated with the pathogenesis of Alzheimer's disease, such as Notch, mTOR and Wnt. However, the potential factors that modulate these pathways and novel molecular mechanisms that might account for the pathogenesis of Alzheimer's disease or for therapy against this disease are still matters of intense research. Teneurins are members of a unique protein system that has recently been proposed as a novel and highly conserved regulatory signaling system in the vertebrate brain, so far related with neurite outgrowth and neuronal matching. The similitude in structure and function of teneurins with other cellular signaling pathways, suggests that they may play a critical role in Alzheimer's disease, either through the modulation of transcription factors due to the nuclear translocation of the teneurins intracellular domain, or through the activity of the corticotrophin releasing factor (CRF)-like peptide sequence, called teneurin C-terminal associated peptide. Moreover, the presence of Ca2+-binding motifs within teneurins structure and the Zic2-mediated Wnt/β-catenin signaling modulation, allows hypothesize a potential crosslink between teneurins and the Wnt signaling pathway, particularly. Herein, we aim to highlight the main characteristics of teneurins and propose, based on current knowledge of this family of proteins, an interesting review of their potential involvement in Alzheimer's disease.
