Detailed knowledge of neuronal connectivity patterns is indispensable for studies of various aspects of brain functions. We previously established a genetic strategy for visualization of multisynaptic neural pathways by expressing wheat germ agglutinin (WGA) transgene under the control of neuron type-specific promoter elements in transgenic mice and Drosophila. In this paper, we have developed a WGA-expressing recombinant adenoviral vector system and applied it for analysis of the olfactory system. When the WGA-expressing adenovirus was infused into a mouse nostril, various types of cells throughout the olfactory epithelium were infected and expressed WGA protein robustly. WGA transgene products in the olfactory sensory neurons were anterogradely transported along their axons to the olfactory bulb and transsynaptically transferred in glomeruli to dendrites of the second-order neurons, mitral and tufted cells. WGA protein was further conveyed via the lateral olfactory tract to the olfactory cortical areas including the anterior olfactory nucleus, olfactory tubercle, piriform cortex and lateral entorhinal cortex. In addition, transsynaptic retrograde labeling was observed in cholinergic neurons in the horizontal limb of diagonal band, serotonergic neurons in the median raphe nucleus, and noradrenergic neurons in the locus coeruleus, all of which project centrifugal fibers to the olfactory bulb. Thus, the WGA-expressing adenovirus is a useful and powerful tool for tracing neural pathways and could be used in animals that are not amenable to the transgenic technology.
