TGFBR3 and Alzheimer disease: Pathway enrichment analysis of TGFBR3-related genes demonstrated that TGFBR3 was strongly involved in Synaptic vesicle cycle, Calcium signaling pathway and Glutamatergic synapse, which have been well-defined in etiology of AD (Ovsepian et al., 2018; Alzheimer’s Association Calcium Hypothesis Workgroup, 2017; Conway, 2020).
