We have obtained monoclonal antibodies to Drosophila acetylcholinesterase, glutamate dehydrogenase as well as other unknown macromolecules which may have some relevance in synaptic function. The majority of antibodies against acetylcholinesterase recognised common epitopes on all four subunits--but one (MA2) was specific to a 110 kDa dimer. Antibodies to unknown synaptic macromolecules were identified by their selective staining in immunofluorescence studies. F2A3 stains sensory neurons and their synapses in the visual and olfactory systems.

The metabolic properties of mitochondria from rat cerebral cortex and olfactory bulb were investigated. The pyruvate-supported oxygen uptake rates by olfactory bulb mitochondria were significantly lower than those by cerebrocortical mitochondria. This is consistent with the differences in pyruvate dehydrogenase complex activities between these mitochondrial preparations. Pyruvate dehydrogenase kinase, NAD-linked isocitrate dehydrogenase, and hexokinase activities in olfactory bulb mitochondria were significantly lower than those in cerebrocortical mitochondria. However, NADP-linked isocitrate dehydrogenase, and NAD-linked and NADP-linked glutamate dehydrogenase activities in olfactory bulb mitochondria were significantly higher than those in cerebrocortical mitochondria. The differences between these two mitochondrial preparations in terms of the activities of these energy-metabolizing enzymes reflect the differences detected in the homogenates of these regions.

Olfactory bulb removal and consequential degeneration of the lateral olfactory tract led to a decrease in the levels of glutaminase and malate dehydrogenase in the ipsilateral olfactory cortex. These changes in enzyme activity may account for the well established decrease in the levels of aspartate and glutamate in the olfactory cortex following ipsilateral bulbectomy. The level of glutamine synthetase, a glial marker enzyme, was slightly increased while the activities of glutamate decarboxylase, glutamate dehydrogenase, and glutamate oxaloacetic transaminase were unchanged.

Neuronal nicotinic acetylcholine receptor (nAChR) expression and function are customized in different brain regions through assembling receptors from closely related but genetically distinct subunits. Immunohistochemical analysis of one of these subunits, nAChRbeta4, in the mouse brain suggests an extensive and potentially diverse role for this subunit in both excitatory and inhibitory neurotransmission. Prominent immunostaining included: 1) the medial habenula, efferents composing the fasciculus retroflexus, and the interpeduncular nucleus; 2) nuclei and ascending tracts of the auditory system inclusive of the medial geniculate; 3) the sensory cortex barrel field and cell bodies of the ventral thalamic nucleus; 4) olfactory-associated structures and the piriform cortex; and 5) sensory and motor trigeminal nuclei. In the hippocampus, nAChRbeta4 staining was limited to dendrites and soma of a subset of glutamic acid dehydrogenase-positive neurons. In C57BL/6 mice, but to a lesser extent in C3H/J, CBA/J, or CF1 mice, a subpopulation of astrocytes in the hippocampal CA1 region prominently expressed nAChRbeta4 (and nAChRalpha4). Collectively, these results suggest that the unique functional and pharmacological properties exerted by nAChRbeta4 on nAChR function could modify and specialize the development of strain-specific sensory and hippocampal-related characteristics of nicotine sensitivity including the development of tolerance.
