1. Path. Tending to attack or affect the nervous system preferentially.
1903Buck's Handbk. Med. Sci. (ed. 2) VI. 270/2 Thus the poisons which have at the same time neurotropic and lipotropic effects..will have a much more marked influence upon the nervous system in an emaciated animal than in one which is very fat. 1922Med. Jrnl. Australia ii. 261/2 Vaccinia is the least neurotropic, while poliomyelitis is the most exclusively neurotropic. 1933Amer. Jrnl. Cancer XIX. 648 Thus the tumor employed is not neurotropic. 1939Lancet 4 Mar. 497/1 (heading) A neurotropic strain of human influenza virus. 1961R. D. Baker Essent. Path. viii. 136 Venoms of snakes are hemolytic or neurotropic. 1973Nature 26 Jan. 247/1 The MV strain of [poliomyelitis] virus..was then shown to be so adapted to monkey brain passage and so neurotropic that it would no longer grow in cells from other organs.
2. Anat. Of or pertaining to the control or regulation of nerves, esp. in relation to their growth and regeneration.
1912Jrnl. Nerv. & Mental Dis. XXXIX. 774 Is the comparative incapacity of the nervous system to regenerate due to some incapacity of the mechanical obstacles, absence of preestablished routes, or to some peculiar defect in the Schwann cells, the chief if not the only elaborators of neurotrophic [sic] material? 1928R. M. May tr. Ramón y Cajal's Degeneration & Regeneration Nervous Syst. I. 374 Several neurotropic currents may act simultaneously on the same cone of growth. Ibid., This fact bears out the view that the neurotropic material is an enzyme segregated by the living cells, instead of a product of the decomposition or disintegration of the nervous tissue. 1968A. F. W. Hughes Aspects Neural Ontogeny i. 33 For Ramon y Cajal the association of a regenerating fibre with the bands of Büngner was an instance of neurotropic attraction. 1968S. Sunderland Nerves & Nerve Injuries xxxii. 405 Whether or not the tissues of the distal stump exert a neurotropic influence on the regenerating process..is still unsettled. |
