摘要:
Compositions and methods to promote nerve regeneration or to confer neuroprotection and prevent or inhibit neuronal degeneration within the nervous system, either the central nervous system or the peripheral nervous system, are provided. Treatment involves administering NS-specific activated T cells, or an NS-specific antigen or analog thereof, a peptide derived therefrom or an analog or derivative of said peptide, or a nucleotide sequence encoding such an antigen or peptide, or any combination thereof.
摘要:
Compositions are provided for promoting nerve regeneration or reducing or inhibiting degeneration in the CNS or PNS to ameliorate the effects of injury or disease. The composition includes an active ingredient selected from:(a) a peptide obtained by modification of a self-peptide derived from a CNS-specific antigen, which modification consists in the replacement of one or more amino acid residues of the self-peptide by different amino acid residues, such modified CNS peptide still being capable of recognizing the T-cell receptor recognized by the self-peptide but with less affinity; (b) a nucleotide sequence encoding such a peptide; (c) T cells activated by such peptide; and (d) any combination of (a)-(c). The peptide is preferably obtained by modification of the self-peptide p87-99 of MBP, more preferably, by replacing lysine 91 with glycine (G91) or alanine (A91) or by replacing proline 96 with alanine (A96).
摘要:
Methods and compositions are provided for preventing or inhibiting neuronal degeneration, or for promoting nerve regeneration, in the central nervous system (CNS) or peripheral nervous system (PNS), or for protecting nerves from glutamate toxicity, which comprises administering to an individual in need thereof an effective amount of the copolymer poly-Glu,Tyr.

Methods and compositions are provided for preventing or inhibiting neuronal degeneration, or for promoting nerve regeneration, in the central nervous system (CNS) or peripheral nervous system (PNS), or for protecting CNS cells from glutamate toxicity, comprising an effective amount of an agent selected from the group consisting of (a) poly-Glu,Tyr and (b) T cells which have been activated by poly-Glue,Tyr.
摘要:
Methods are provided for treating injury to or disease of the central or peripheral nervous system. In one embodiment, treatment is effected by administering activated T cells that recognize an antigen of Cop 1 or a Cop 1-related peptide or polypeptide to promote nerve regeneration or to prevent or inhibit neuronal degeneration within the nervous system. In another embodiment, treatment involves administering Cop 1 or a Cop 1-related peptide or polypeptide to promote nerve regeneration or to prevent or inhibit neuronal degeneration in the nervous system, either the central nervous system or the peripheral nervous system. The activated T cells, which have been activated by the presence of Cop 1 or a Cop 1-related peptide or polypeptide, can be administered alone or in combination with Cop 1 or a Cop 1-related peptide or polypeptide.

摘要:
The present invention is directed to peptides of the formulas (i) Xaa-Yaa-Arg, wherein either Xaa is any amino acid residue and Yaa is Glu or Xaa is absent and Yaa is any amino acid residue with the exception of Pro; (ii) Arg-Yaa-Xaa, wherein either Xaa is any amino acid residue and Yaa is Glu or Xaa is absent and Yaa is any amino acid residue with the exception of Asn; (iii) Xaa-Arg-Yaa, wherein Xaa is any amino acid residue and Yaa is Glu; and (iv) Yaa-Arg-Xaa, wherein Xaa is any amino acid residue and Yaa is Glu, and to derivatives thereof, which exert an inhibitory effect on macrophage migration and/or macrophage phagocytic activity. In addition, the peptides and derivatives thereof exert an inhibitory effect on the ability of macrophages and T cells to adhere to extracellular matrix and/or fibronectin. The peptides and derivatives thereof exert an inhibitory effect on a humoral and/or cellular immune response. The invention is also directed to methods for use of the peptides and derivatives thereof and compositions containing them for the inhibition of inflammation, including but not limited to, inflammation at a joint, in the central nervous system generally, at specific lesions in the central nervous system, and other immune privileged sites.
摘要:
A process for the manufacture of human mononuclear phagocytic leukocytes comprises incubating monocytes isolated from a blood sample of an individual and skin segments from the same individual, removing the dermis segments from the incubation mixture and sedimenting the obtained activated mononuclear phagocytic leukocytes by centrifugation, washing and resuspending the activated phagocytic leukocytes in the medium, and evaluating the culture for its suitability for human administration. Cellular therapy products are made from the obtained cultures and are useful for promoting axonal regeneration in the CNS, wound healing and treatment of myocardial infarction.
摘要:
Methods and compositions are provided for treatment of neurodegenerative diseases in which there is accumulation of misfolded and/or aggregated proteins, excluding prion diseases. In particular, the invention relates to treatment of the neurodegenerative diseases Huntington's disease (HD), Alzheimer's disease (AD) or Parkinson's disease (PD), by administration of an agent selected from the group consisting of (i) Copolymer 1, (ii) a Copolymer 1-related peptide, (iii) a Copolymer 1-related polypeptide, and (iv) T cells activated with (i), (ii) or (iii).
摘要:
Peptides derived from CNS-specific antigens, altered peptide ligands (APL) analogues of said peptides, T cells activated by such peptides, poly-YE, and any combination of said agents are useful for prevention, treatment and/or alleviation of anxiety disorders, particularly post-traumatic stress disorder, and for restoring BDNF levels in the brain of an individual after reduction of BDNF expression induced by stress.
