Definitions

  • the invention refers to a nerve growth factors (NGF) for use in the prevention and treatment of viral 5 infections caused by viruses known as enveloped viruses, for example, alpha type herpes viruses such as, e.g., type 1 herpes simplex virus (HSV-1), type 2 herpes simplex virus (HSV-2) and herpes varicel ⁇ la/zoster; beta or gamma type herpes viruses, e.g., 0 cytomegalovirus; or retroviruses, e.g. a human immu ⁇ nodeficiency virus, which is responsible for the acquired immunodeficiency syndrome and the virus responsible for the Moloney Sarcoma (MSV) .
  • alpha type herpes viruses such as, e.g., type 1 herpes simplex virus (HSV-1), type 2 herpes simplex virus (HSV-2) and herpes varicel ⁇ la/zoster
  • beta or gamma type herpes viruses e.g., 0 cytome
  • NGF nerve growth factors
  • NGF mammalian NGF
  • ⁇ -NGF ⁇ subunit
  • NGF is thought to play a key role in the survival of cholinergic neurons in the central nervous system and this has led to propose its use in the treatment of Alzheimer's disease. It has now been found that nerve growth factors are capable of preventing the growth and the infectiousness of certain viruses.
  • This invention therefore provides use of a nerve growth factor in the preparation of a medicament for use in the prevention or treatment of viral infection caused by an enveloped virus.
  • a NGF can therefore be used in accordance with the invention in the prevention or treatment of viral infections caused by enveloped viruses like alpha type herpes viruses, such as HSV-l,HSV-2 and herpes vari ⁇ cella/zoster; beta or gamma type herpes viruses, e.g., cytomegalovirus; or retroviruses, e.g. a HIV such as HIV-1 or HIV-2, and MSV.
  • enveloped viruses like alpha type herpes viruses, such as HSV-l,HSV-2 and herpes vari ⁇ cella/zoster
  • beta or gamma type herpes viruses e.g., cytomegalovirus
  • retroviruses e.g. a HIV such as HIV-1 or HIV-2, and MSV.
  • viruses towards which a NGF has proved to be effective accor ⁇ ding to the invention are, e.g. HSV-1, HSV-2 and MSV.
  • a (NGF) for use according to the invention can be
  • a subunit of a NGF for use according to the invention may be ⁇ , ⁇ or Vsubunit, preferably the ⁇ -subunit.
  • An analogue of the nerve growth factors according to the invention can also be e.g., a mutein deriving from the aforementioned NGF polypeptides, subunits and analogues, both in amidated and non-amidated form, by replacement and/or deletion of one or more aminoacids, which retains equivalent properties, in particular an equivalent capacity to bind itself to the NGF receptor.
  • a specific example of NGF for use according to the invention is a NGF which is obtained from Vipera lebetina and which is a commercially available product.
  • HSV-1 and HSV-2 were grown on the heteroploid cellular strain of epithelioid carcinoma Hep # 2.
  • MEM Eagle's minimum essential medium
  • CPE virus-induced cytopathogenicity
  • the percentage of reduction of CPE in the treated cultures compared to the infected controls was transferred onto semilogarithmic coordinate paper.
  • the same cultures were then frozen in order to titrate the viral contents (I.V.).
  • the cryolysates were then titrated according to one of the standard techniques for determining plaques on confluent monolayers of Hep # 2 cells grown on lamellas in Leighton tubes, using methylcellulose culture medium.
  • the I.V. titre under the various experimental conditions was given as PFU/ml.
  • the significance of differences between the controls and treated cultures was ⁇ evaluated by means of the Dunnet test (*p ⁇ 0.01).
  • Moloney sarcoma virus prepared from virus- induced tumors in newborn Balb/c mice was tested on murine embryo fibroblasts Balb/3T3 grown on MEM cont ⁇ aining 10% foetal calf serum.

  • the growth medium was replaced by 1 ml of test medium containing fourfold serial dilutions of NGF. After 1 hour incubation, cell cultures were infected with 40 focus-forming units of MSV in 0.2 ml of test medium. After 3 days, the foci of transfor ⁇ mation in cell cultures were counted at 35x magnifi ⁇ cation and the percentage of reduction in the treated cultures conmpared to the infected controls was plotted on a semilogaritmic scale.
  • Figure 1 shows the percentage of inhibition of CPE of vipera lebetina commercial NGF obtained from Serva, on the HSV-1 (HF strain) virus infection obtained in a cell suspension of HEp # 2 cells : percent values of CPE reduction (ordinate) are plotted against NGF conc ⁇ entration values (abscissa).
  • Figure 2 shows the percentage of inhibition of CPE of the same NGF on the HSV-2 (G strain) virus infection obtained in a cell suspension of Hep # 2 cells : percent values of CPE reduction (ordinate) are plotted against NGF concentration values (abscissa).
  • Figure 3 shows the activity of NGF in comparison to control (histogram of the left) estimated as a decrease in the production of HSV-1 (HF strain) infectant virus in Hep # 2 cell cultures : the histograms give, as the ordinate, the viral index in 10 4 PFU/ml in the various experimental groups and, as the abscissa, the NGF concentration values.
  • Figure 4 shows the activity of NGF in comparison to control (histogram on the left) estimated as a decrease in the production of HSV-2 (G strain) infectant virus in Hep # 2 cell cultures : the histograms give, as the ordinate, the viral index in 10 2 PFU/ml in the various experimental groups and, as the abscissa, the NGF concentration values.
  • Figure 5 shows the inhibitory effect of NGF on the MSV induced transformation of Bolb/3T3 cells : percent valus of Foci reduction (ordinate) are plotted against NGF concentration values (abscissa).
