Abstract

The effect of the nerve growth factor antiserum (NGF-AS) on adult mice has been studied at morphological and biochemical levels. A 5-day treatment of 3-month-old mice results in a marked volume reduction of sympathetic chain ganglia. This decrease in volume appears to be due in part to cell death, but to a major extent to atrophy of residual neurons. A severe impairment of the sympathetic function also obtains, as indicated by a marked decrease of catecholamine uptake and content in peripheral organs. A few weeks after the end of treatment, a gradual and progressive recovery of the sympathetic function ensues, and the nerve cells regain their normal appearance. These results are described in connection with the problem of the site of action of NGF antibodies in immature and in fully differentiated sympathetic neurons.

    The primary test article related effect in these studies was on neuron size. Atrophy of sympathetic ganglion neurons has been reported to occur in association with anti-nerve growth factor states in rodents (Angeletti et al., 1971; Ruit et al., 1990). Increased glial cell density was a secondary effect, as the glial cells were generally more tightly packed due to the reduction in neuron size.

    During late embryonic and early postnatal development both sensory and sympathetic neurons require NGF for survival and maturation (Crowley et al., 1994; Smeyne et al., 1994; Glebova and Ginty, 2004). However, while it appears these neurons become independent of NGF as they mature (Kole et al., 2013), there are a number of reports (Angeletti et al., 1971; Gorin and Johnson, 1980; Johnson et al., 1982; Ruit et al., 1990; Hoffman et al., 2011) that suggest NGF is required for survival of neurons in adult animals. Early studies reported that suppression of NGF by polyclonal antisera in adult animals decreased the volume of sympathetic chain ganglia and/or decreased the size of the associated neurons following both acute (Levi-Montalcini and Booker, 1960; Angeletti et al., 1971; Bjerre et al., 1975; Goedert et al., 1978) and chronic (Otten et al., 1979; Gorin and Johnson, 1980; Johnson et al., 1982; Ruit et al., 1990; Ruberti et al., 2000) treatments.

    Even at exposures well above therapeutic levels for up to 6 months, primates treated with tanezumab did not reveal any significant pharmacologically mediated toxic or adverse effects on any organ systems including the nervous system. Our results contrast with an extensive body of literature describing the adverse effects of NGF anti-serum treatment on sensory and sympathetic ganglia in rodents (Angeletti et al., 1971; Ruit et al., 1990; Schwartz et al., 1982). For example, anti-NGF has been associated with pronounced biochemical and morphological atrophy of the superior cervical ganglion and a reduction in neuronal number in the adult rat (Gorin and Johnson, 1980; Johnson et al., 1989); the disappearance of adrenergic nerve terminals in several peripheral tissues in the adult mouse (Bjerre et al., 1975); and a reduction in the substance P content of sensory ganglia, spinal cord, and hind paw skin in adult rats and guinea pigs (Schwartz et al., 1982).
